Abstract: The role of bromide in the formation and speciation of disinfection by-products
(DBPs) during chlorination was investigated. The molal ratio of applied chlorine to
bromide is an important factor in the formation and speciation of trihalomethanes (THMs)
and halogenacetic acids (HAAs). A good relationship exists between the molar fractions of
THMs and the bromide incorporation factor. The halogen substitution ability of HOBr and
HOCl during the formation of THMs and HAAs can be determined based on probability
theory. The formation of HAAs, and their respective concentrations. can also be
estimated through use of the developed model. (C) 2001 Elsevier Science Ltd. All rights

Abstract: Biogeochemical processes mediated by microorganisms in river sediments
(hyporheic sediments) play a key role in river metabolism. Because biogeochemical
reactions in the hyporheic zone are often limited to the top few decimetres of sediments
below the water-sediment interface, slow filtration columns were used in the present
study to quantify biogeochemical processes (uptakes of O-2, DOC, and nitrate) and the
associated microbial compartment (biomass, respiratory activity, and hydrolytic activity)
at a centimetre scale in heterogeneous (gravel and sand) sediments. The results
indicated that slow filtration columns recreated properly the aerobic-anaerobic gradient
classically observed in the hyporheic zone. O-2 and NO3- consumptions (256 +/- 13 mu
g of O-2 per hour and 14.6 +/- 6.1 mu g of N-NO3- per hour) measured in columns were
in the range of values measured in different river sediments. Slow filtration columns also
reproduced the high heterogeneity of the hyporheic zone with the presence of anaerobic
pockets in sediments where denitrification and fermentation processes occurred. The
respiratory and hydrolytic activities of bacteria were strongly linked with the O-2
consumption in the experimental system, highlighting the dominance of aerobic
processes in our river sediments. In comparison with these activities, the bacterial
biomass (protein content) integrated both aerobic and anaerobic processes and could be
used as a global microbial indicator in our system. Finally, slow filtration columns are an
appropriate tool to quantify in situ rates of biogeochemical processes and to determine
the relationship between the microbial compartment and the physico-chemical
environment in coarse river sediments. (c) 2005 Elsevier Ltd. All rights reserved.

Abstract: The release of colloids to groundwater was investigated in situ in an ironoxyhydroxide-rich, sandy aquifer. Groundwater amended with various solutes was
injected into and immediately withdrawn from the shallow aquifer. Turbidity and colloid
composition were monitored in the retrieved injectate. The response of the aquifer
material to the amendments generally mimicked that observed in an earlier study using
packed columns containing the sediment, demonstrating the viability of the single-well
method for testing colloid mobilization in situ. The decline of turbidity in the retrieved
injectates with increasing withdrawal volume was analyzed to determine a "reaction
order" n, describing the redeposition of mobilized colloids to the immobile matrix,
Differences in the reaction order for the amendments tested presumably indicated the
effectiveness of these amendments to generate repulsive colloid-immobile matrix
interactions.

Abstract: A kinetic expression for oxygen, nitrate, nitrite and nitrous oxide reduction in
soil was developed. The formulation was based on competitive Michaelis-Menten kinetics
for a steady microbial population whose respiratory activity was assumed to be constant
so that the number of electrons produced per unit of time was constant. Competition
among the electron accepters was characterized by their affinity toward the electron and
by their concentration. Several different Values for the affinity coefficients were used to
simulate the concentration of O-2, NO3-, NO2-, N2O and N-2 at various times. When
relative magnitudes of affinity coefficients were chosen to be 100 000, 1, 100 and 0.1, for
O-2, NO3-, NO2- and N2O, respectively, the temporal plot of concentration showed that
the disappearance of O-2 and NO3- was zero order. The accumulation of NO2- was very
small and it was rapidly reduced to N2O. The production rate of N2O was nearly zero
order but the magnitude of the rate was rather small as opposed to the rate of
disappearance of NO3-. The reduction of N2O to N-2 took place only after NO3- had
almost disappeared. With these competition parameters NO3- was stable in the presence
of O-2. The reduction of N2O was also very much retarded in the presence of NO3-. NO2was relatively unstable, even in the presence of O-2, and it was further reduced to N2O.
With the relative magnitude of the chosen affinity coefficients, the kinetic formulation
effectively simulated the ''inhibitory'' effect of O-2 upon the denitrification process, and
the ''inhibitory'' effect of NO3- and NO2- upon the reduction of N2O to N-2.

Abstract: Riverbank filtration relies on the stream bed and aquifer matrixes to reduce
pathogens under varying conditions of induced infiltration resulting from changes in river
stage and flow velocity. The Greater Cincinnati (Ohio) Water Works monitored hydrologic
parameters and water quality at its Charles M. Bolton Well field during a comprehensive
flowpath study. The study determined the frequency of occurrence of high river-stage
events from historical data and monitored hydrologic parameters to estimate the
potential unit infiltration rate. Giardia, Cryptosporidium, algae, spores, particle counts,
and turbidity were also monitored. The project investigated potential pathogen/surrogate
breakthrough during several high river-stage and infiltration events. High-stage events
occurred less than 4% of the time. Giardia and Cryptosporidium were not detected in any
groundwater samples. Increases in surrogate concentrations were minimal and
maintained > 3.5-log reduction. The streambed and aquifer have the ability to buffer
water quality effects from major increases in the infiltration rate.

filtrated water is an important component of the drinking water production, In this case,
most of the water pumped from the alluvial aquifers originates from the adjacent river.
Bank filtration is generally considered beneficial both quantitatively and qualitatively.
However, in some cases bank filtration ran cause deleterious effects to groundwater
quality. This paper describes such a case, focusing on ammonium (NH4) concentrations.
The data were gathered at an experimental bank-filtration site which is part of a large
well field along the Seine River (France). At this site, groundwater was sampled along a
how line path and pore water of river bed sediments was collected with peepers or by
centrifuging core samples. The pore waters of the superficial river bed sediments have
high ammonium concentrations (>30 mg NH4 L-1) whereas, in the groundwater, these
concentrations are lower (less than or equal to 20 mg NH4 L-1), with higher
concentrations near the bank. The high NH4 concentration in the sediment is related to
the heavy organic load in the river and the mineralization of this organic matter by
benthic microflora. Among the different mechanisms that influence NH4 transport and
retention in the porous medium, it emerges that sorption by the alluvial sediments (K-d
approximate to 1 - 10 x 10(-3) m(3) kg(-1)), or even the chalk (K-d approximate to 48 x
10(-3) m(3) kg(-1)) seems to be effective in retaining NH4, This is illustrated by a model
of NH4 transfer with retardation adapted to the conditions of

Abstract: River-recharged aquifers are developed for drinking water supplies in many
parts of the world. Often. however. dissolved organic carbon (DOC) present in the
infiltrating river water causes biogeochemical reactions to occur in the adjacent aquifer
that create elevated Mn and Fe. Mn concentrations in groundwater from some of the
production wells installed in the aquifer at Fredericton, New Brunswick exceed the
Canadian Drinking Water Guideline of 9.1 x 10(-4) mmol/l by up to 5.5 x 10(-2) mmol/l
has previously been hypothesized that the influx of DOC from the Saint John River is
causing bacterially mediated reductive dissolution of Mn oxides in the aquifer system,
leading to elevated aqueous Mn concentrations. Previous work was limited to the
collection of water samples from production wells and several observation wells installed
in the glacial ourwash aquifer. The objective of this study was to investigate the
biogeochemical controls on Mn concentrations using sand-filled columns. One column was
inoculated with bacteria while a second column was treated with ethanol in order to
decrease the microbial population initially present in the system. Both columns received
the same influent solution that contained acetate as a source of DOC. The results of the
experiments suggested that the two main controls on Mn concentrations in the columns
were microbially mediated reductive dissolution of Mn oxides and cation exchange. The
conceptual model that was developed based on the experimental data was supported by
the results obtained using a one-dimensional reactive-transport model. The reductive
dissolution of Mn oxides in the aquifer sands could be adequately simulated using dualMonod kinetics. Similar trends are observed in the experimental data and field data
collected from Production Well 5. located in the Fredericton Aquifer. From the
experiments. it is evident that cation-exchange reactions may be an important
geochemical control on Mn concentrations during the initial stages of pumping: however.
the reductive dissolution of Mn oxides may represent a long-term source of Mn in the
drinking water supply. (C) 2004 Elsevier B.V. All rights reserved.

Abstract: Around 70% of Berlin's drinking water derives from bank filtration or artificial
recharge. A major advantage of bank filtration is the capability of the subsurface to
remove contaminants and save natural groundwater resources. Because the surface
water contains elevated amounts of treated sewage, Berlin's system is a semi-closed
water cycle relying partly on indirect wastewater reuse. A number of wastewater residues
can be traced in the groundwater and serve as a tool to characterise the bank filtration
systems. Conservative tracers such as some wastewater indicators and stable isotopes
are used to estimate flow velocities and proportions of bank filtrate in the abstraction
wells prior to reactive transport evaluations. Examples of tracer applications in the Berlin
system are presented in this paper. In addition, an overview is given of results of various
studies conducted on contaminant transport and their removal during underground
passage of the bank filtrate in Berlin.

Abstract: Biogeochemical processes occurring during infiltration of surface water from
the Lot River into an alluvial aquifer are described using chloride as a natural tracer of
water mixing in a well field where a Cl- rich aquifer water is recharged with a Cl--poor
river water. Near the river bank a slightly reduced zone (depleted in O2, DOC, NO3, Na,
and K and enriched in Mn, Ca, Mg, bicarbonate, and silica) is observed. Sulfate behaves
conservatively. Nearest to the infiltration zone some of the pH-regulating processes are
not at equilibrium. These phenomena can all be explained by bacterial degradation of
organic matter in the river bank sediments and weathering of minerals along the
infiltration path. In some cases (degradation of DOC and dissolution of calcium and
magnesium carbonates) a semiquantitative confirmation of the stoichiometry of the
reactions is given. Zinc is efficiently filtered after the first 10-15 m of the bank sedimentalluvion system. Some chemical changes occurring in the reduced zones are reversible
(depletion of dissolved oxygen, dissolution of Mn). Others are not.

Abstract: Ecological constraints in subsurface environments relate directly to
groundwater flow, hydraulic conductivity, interstitial biogeochemistry, pore size, and
hydrological linkages to adjacent aquifers and surface ecosystems. Groundwater ecology
has evolved from a science describing the unique subterranean biota to its current form
emphasising multidisciplinary studies that integrate hydrogeology and ecology. This
multidisciplinary approach seeks to elucidate the function of groundwater ecosystems and
their roles in maintaining subterranean and surface water quality. In aquifer-surface
water ecotones, geochemical gradients and microbial biofilms mediate transformations of
water chemistry. Subsurface fauna (stygofauna) graze biofilms, alter interstitial pore size
through their movement, and physically transport material through the groundwater
environment. Further, changes in their populations provide signals of declining water
quality. Better integrating groundwater ecology, biogeochemistry, and hydrogeology will
significantly advance our understanding of subterranean ecosystems, especially in terms
of bioremediation of contaminated groundwaters, maintenance or improvement of
surface water quality in groundwater-dependent ecosystems, and improved protection of
groundwater habitats during the extraction of natural resources. Overall, this will lead to
a better understanding of the implications of groundwater hydrology and aquifer geology
to distributions of subsurface fauna and microbiota, ecological processes such as carbon
cycling, and sustainable groundwater management.

Abstract: River infiltration into a sand and gravel aquifer was investigated to assess the
importance of dentrification in maintaining low-NO3- groundwater supplies. Samples from
the River Elbe and groundwater sampling points along a section of the aquifer were
analysed for dissolved organic carbon, major ions and the N-15/N-14 isotopic ratio of
dissolved NO3-. Input of NO3- to the aquifer is influenced by seasonal, temperaturedependent denitrification in the river bed sediments. Along an upper flowpath in the
aquifer from the River Elbe to a sampling point at a distance of 55 m, the median NO3concentration decreased by 4.8 mg litre(-1) and the delta(15)N composition increased by
+ 9.0%, consistent with denitrification. Similar isotopic enrichment was demonstrated in
a laboratory column experiment with a reduction in NO3- of 10.5 mg litre(-1) for an
increase in delta(15)N of + 9.8%, yielding an isotopic enrichment factor of -14.6%. A
mass balance for denitrification shows that oxidizable organic carbon required for
denitrification is derived from both the infiltrating river water and solid organic matter
fixed in the river bed sediments and aquifer material. (C) 1998 Elsevier Science Ltd. All

Abstract: Artificial recharge of urban aquifers with stormwater has been used
extensively in urban areas to dispose of stormwater and compensate for reduced
groundwater recharge. However, stormwater-derived sediments accumulating in
infiltration beds may act as a source of dissolved contaminants for groundwater.
Concentrations of hydrocarbons, heavy metals, nutrients and dissolved oxygen (DO) were
monitored at multiple depths in shallow groundwater below a stormwater infiltration
basin retaining large amounts of contaminated organic sediments. Multilevel wells and
multiparameter loggers were used to examine changes in groundwater chemistry
occurring over small spatial and temporal scales. Rainfall events produced a plume of
low-salinity stormwater in the first 2 m below the groundwater table, thereby generating
steep vertical physico-chemical gradients that resorbed during dry weather. Heavy metals
and hydrocarbons were below reference concentrations in groundwater and aquifer
sediments, indicating that they remained adsorbed onto the bed sediments. However,
mineralization of organic sediments was the most probable cause of elevated
concentrations of phosphate and DOC in groundwater. DO supply in groundwater was
severely limited by bed respiration which increased with temperature. Cold winter
stormwater slightly re-oxygenated groundwater, whereas warm summer stormwater
lowered DO concentrations in groundwater. Among several results provided by this study,
it is recommended for management purposes that infiltration practices should minimize
the contact between inflow stormwater and organic sediments retained in infiltration
basins. (C) 2004 Elsevier B.V. All rights reserved.

Abstract: The migration of zinc through river bank sediments is studied in column
experiments. Even when the initial dissolved zinc is low enough to prevent precipitation
of zinc minerals in the column, adsorption processes strongly retard the transport of the
metal with respect to water. Organic matter, when dissolved, can significantly increase
the mobility of Zn. Small pH variations are as important as organic matter in the control
of the solubility and transport of zinc. The adsorption of zinc seems to control, at least
partially, the solubility of organic matter (most likely as ternary surface complexes of the
form solid-Zn-organics). Dissolved organic matter and pH are therefore master variables
for the understanding of zinc transport through river bank sediments.

Abstract: The wetland soils of the Mulde river in the industrial district of BitterfeldWolfen (Germany) are highly contaminated with heavy metals and arsenic. We studied
the mobility of accumulated heavy metals and arsenic and the influence of dissolved
organic matter (DOM) on element mobility. Undisturbed soil cores were taken from five
different sites to represent a wide range of heavy-metal contamination, soil properties
and dissolved organic carbon (DOG) concentrations. The acid-soluble concentrations
(mostly equal to the total content) were up to 1100 mg kg(-1) for Zn, 800 mg kg(-1) for
Cr, 364 mg kg(-1) for Cu, 265 mg kg(-1) for As and 37 mg kg(-1) for Hg, depending on
the sampling site. Percolation experiments using small lysimeters with undisturbed topsoil
cores illustrated a considerable mobilization of Zn, Cd, Cu, Cr and Hg, depending on soil
properties. Up to 80 mu g 1(-1) Cd, 8 mg 1(-1) Zn, 130 mu g 1(-1) Cr, 160 mu g 1(-1)
Cu and 7 mu g 1(-1) Hg were detected in the soil percolates. Arsenic mobilization was
low. The concentration of Cr, Hg, Cu and As in the soil percolates was positively
correlated with DOM. Besides the element content (mobile or acid-soluble), soil pH and
soil characteristics describing the soil potential for heavy-metal adsorption (clay, oxides,
cation exchange capacity), the DOC concentration in the soil solution should be known to
access the potential mobilization of Hg, Cr, Cu and As. In contrast, Cd and Zn
mobilization depends on soil pH and mobile element content, but not on DOM. Additional
studies on two soil profiles (down to 1.5 m) confirmed the translocation of heavy metals
from the highly contaminated topsoil into deeper soil horizons and into the groundwater
and the influence of DOM as revealed with the percolation experiment. Our results also
showed that DOM is of minor importance on the mobilization of heavy metals in soils with
a low soil pH (< 4.5). (C) 1998 Elsevier Science B.V.

Abstract: We have separated two groups of copper-complexing ligands (the weak and
strong ligands) from streamwaters in the Lake Biwa watershed by modified immobilized
metal ion affinity chromatography (IMAC). The weak ligands were about 0.54-1.21% of
the total dissolved organic matter (DOM), as determined by UV absorbance, and the
strong ligands were about 0.06-0.21%. The results show that the stronger ligands were
retained longer on the IMAC column, eluted later, and were accompanied by shorter
wavelength UV absorbers, fluorescence maxima patterns with shorter wavelength
excitation, and relatively "fresher" organic matter. The weak ligands with logK ' (CuL)
values of 6.6-7.7 had predominant humic-like fluorescence and may have been
considerably degraded, while stronger ligands with logK ' (CuL)values of 8.9-9.3 had only
protein-like fluorescence and were relatively newly produced, labile material, as indicated
from their amino acid composition. The protein-like fluorescence was mainly due to
aromatic tryptophan probably bound to proteins or peptides. The results presented here
have significant implications regarding the possible sources and biogeochemical role of
organic ligands in aquatic environments.

Abstract: Overbank sediments occur along rivers and streams with variable water
discharge. They are deposited on floodplains and levees from water suspension during
floods, when the discharge exceeds the amounts that can be contained within the normal
channel. Overbank sediments were introduced as a sampling medium in geochemical
mapping in 1989, and a number of studies have later been published on this subject.
These papers indicate:
1. Depth integrated samples of overbank sediments reflect the composition of many
current and past sediment sources upstream of the sampling point, contrary to active
stream sediments, which originate in a more restricted number of presently active
sediment sources from which they move regularly along the stream channel. In many
regions overbank sediments are more representative of drainage basins than active
stream sediments and can, therefore, be used to determine main regional to continental
geochemical distribution patterns with widely scattered sample sites at low cost per unit
area.
2. Samples of overbank sediments can be collected in floodplains or old terraces along
laterally stable or slowly migrating channels. In some locations the surface sediments
may be polluted, however, natural, pre-industrial sediments may, nevertheless, occur at
depth. Mapping of the composition of recent and pre-industrial overbank sediments can,
therefore, be used (i) in a characterization of the present state of pollution, and (ii) as a
regional prospecting tool in natural as well as polluted environments.
3. Vertical movements of elements in strata of overbank sediments may occur, especially
in cases where the distribution of relatively mobile elements in non-calcareous areas are
heavily influenced by acid rain. However, the overall impression is that vertical migration
of chemical elements is not a major problem in the use of overbank sediments in
geochemical mapping.
4. The composition of overbank sediment is of great interest to society in general, since
flood plains are very important for agriculture, urbanisation, and as sources for drinking
water.
Several of the above points indicate that overbank sediments represent a natural
analogue to the products of bed-blending. This aspect is mentioned here in light of the
Theory of Sampling (TOS). (C) 2004 Elsevier B.V. All rights reserved.

Abstract: Reproducibility of overbank sediment sampling was tested in twenty-nine
floodplains in Europe, ten in Greece and nineteen in Norway, by the collection of duplicate
pairs of samples. Distances between duplicate sites in Greece were 60 to 100 m, and in
Norway 100 to 200 m. In Norway the same nineteen floodplains were sampled by a
second team for the purpose of investigating differences in sampling variability and
technique. Total element contents were determined in all samples. Paired samples were
compared by calculating Spearman's rank correlation coefficient on the raw analytical
data, and one-way analysis of variance on the log-transformed data. Pairs of overbank
sediment samples collected from different floodplains by the Hellenic team and the first
Norwegian team showed high rank correlations and low within-basin variability (sampling
and analytical variance). Statistical results of the second Norwegian team were
comparatively poorer; both Spearman's rank correlation coefficient and one-way analysis
of variance, showed very low positive to negative correlations and high within-basin
variation, suggesting a non-uniform distribution of elements in the Norwegian overbank
sediment sequences and differences in the sampling technique of the two teams.
Nevertheless, careful location of sample sites, as has been done by the Hellenic and the
first Norwegian teams, reduces considerably the sampling variability, and the overall
sampling reproducibility for most elements is very good for distances up to 100 m in
Greece and 200 m in Norway, provided correlated overbank sediment sequences are
sampled. The implication of this study for multinational regional geochemical mapping is
that overbank sediment sampling must be carried out by well-trained professional teams
of exploration geochemists, and where possible by one sampling team for the whole
country. (C) 1997 Elsevier Science B.V.

Title: Small-scale spatial and temporal variance in the concentration of heavy
metals in aquatic sediments: a review and some new concepts

Abstract: Uncertainty associated with data derived by the analyses of heavy metals in
aquatic sediment is due to variance produced in the laboratory (precision), plus 'natural',
small-scale spatial variance, (or field variance) at the sampling site. Precision is easily
determined and is usually reported in contaminant studies, but field variance is poorly
understood and seldom documented. It is important to have an understanding of the field
variance because if small-scale spatial variance in the concentration of heavy metals is
excessive, regional trends may be of limited value. Similarly, if temporal change is large,
the results of single synoptic surveys may be questionable and the ability to demonstrate
anthropogenic contributions over time will be difficult. However, it is evident from the
literature that the information needed to address problems of spatial and temporal
variance in the field is beyond the resources of most researchers. Analytical precision of
about 5% relative standard deviation (RSD) for heavy metal analysis is typical of a wellmanaged laboratory. Many studies of small-scale spatial variability made during the
current investigation indicate that field variance is related to ambient energy and to the
type of sedimentological environment. Total variance (analytical plus field variance) is
approximately 10% RSD (mean for a suite of nine trace elements) fur depositional parts
of estuaries and the marine environment, but increases to about 20-35% RSD for the
more dynamic parts of the estuarine environment and the fluvial system. Repeated
sampling over periods of up to 7 years undertaken during the present study, indicate a
similar order of magnitude for temporal variability in these sedimentological
environments. A proposed scheme to provide information on field variance is to
undertake small-scale spatial and temporal studies in discrete sedimentological
environments in the study area after sediment sampling and characterisation has been
completed. The comparatively large proportion of total variance associated with smallscale spatial and temporal variability in the field questions the often excessive cost and
effort made in attempting minor reductions in analytical precision in contaminant
investigations. (C) 2001 Elsevier Science Ltd. All rights reserved.

Title: CHARACTERIZING THE INFLUENCE OF SURFACE-WATER ON WATER

Abstract: Waterborne particulates, turbidity, and temperature were used to characterize
the influence of surface water on collector wells constructed in alluvial river valleys. No
insects, other macroorganisms, Giardia, or other large-diameter pathogens were found in,
water from the collector wells, although Giardia were detected in adjacent rivers. The
turbidity of the water produced by the collector wells remained virtually constant
throughout the year and did not fluctuate with changes in river turbidity. These results
support the conclusion that the influence of surface water on collector wells should not be
characterized as "direct." Temperature data, however, show that the collector wells are
influenced by the surface water, but these data alone are insufficient for deciding whether
this influence is direct.

Abstract: Biogeochemical processes within riverbed hyporheic zones (HZ) can potentially
impact the fate and transport of contaminants. We evaluated a modified freeze core
technique for the collection of intact cobble-bed samples from the Columbia River HZ
along a stretch of the Hanford Reach in Washington State and investigated
microbiological and geochemical parameters of corresponding frozen and unfrozen
samples. During three sampling periods (March, May, and November 2000), relatively
high numbers of viable aerobic heterotrophic bacteria were recovered from both unfrozen
(10(6)-10(7) cfu/g) and frozen samples (10(5)-10(6) cfu/g). Relatively large populations
of sulfate-, nitrate-, and iron-reducing bacteria were present, and significant
concentrations of acid-volatile sulfide were measured in some samples, indicating that
anoxic regions exist within this zone. Cr(VI), a priority groundwater pollutant on adjacent
U.S. Department of Energy lands, was probably removed from solution in HZ samples by
a combination of microbial activity and chemical reduction, presumably via products of
anaerobic microbial metabolism. These results suggest that biogeochemical processes in
the Columbia River HZ may contribute to the natural attenuation of Cr(VI). Although
freezing modestly diminished recovery of viable bacteria, freeze core techniques proved
reliable for the collection of intact hyporheic sediments.

Abstract: Water quality transformations during soil aquifer treatment at the Mesa
Northwest Water Reclamation Plant (NWWRP) were evaluated by sampling a network of
groundwater monitoring wells located within the reclaimed water plume. The Mesa
Northwest Water Reclamation Plant has used soil aquifer treatment (SAT) since it began
operation in 1990 and the recovery of reclaimed water from the impacted groundwater
has been minimal. Groundwater samples obtained represent travel times from several
days to greater than five years. Samples were analyzed for a wide range of organic and
inorganic constituents. Sulfate was used as a tracer to estimate travel times and define
reclaimed water plume movement. Dissolved organic carbon concentrations were reduced
to approximately 1 mg/L after 12 to 24 months of soil aquifer treatment with an applied
DOC concentration from the NWWRP of 5 to 7 mg/L. The specific ultraviolet absorbance
(SUVA) increased during initial soil aquifer treatment on a time-scale of days and then
decreased as longer term soil aquifer treatment removed UV absorbing compounds. The
trihalomethane formation potential (THMFP) was a function of the dissolved organic
carbon concentration and ranged from 50 to 65 mu gTHMFP/mgDOC. Analysis of trace
organics revealed that the majority of trace organics were removed as DOC was removed
with the exception of organic iodine. The majority of nitrogen was applied as nitratenitrogen and the reclaimed water plume had lower nitrate-nitrogen concentrations as
compared to the background groundwater. The average dissolved organic carbon
concentrations in the reclaimed water plume were less than 50% of the drinking water
dissolved organic concentrations from which the reclaimed water originated.

Abstract: A high-resolution sediment core (sedimentation rate similar to2 mm/year)
from the German Bight was analysed for its foraminiferal stable oxygen isotope
(delta(18)O) composition. These data were correlated with instrumental summer seasurface temperature and salinity data from the nearby island of Helgoland, reaching back
100 years. Comparing the isotope data with the instrumental records reveals a distinct
delta(18)O-salinity relationship (delta(18)O=0.34xS-9.36; r=0.86) for the German Bight,
where salinity is mainly driven by freshwater input from the Elbe River. Thus, these
findings provide the possibility for future regional paleosalinity and paleodischarge
reconstructions for times far beyond the instrumental timescale.

Abstract: The identification of denitrification in the Torgau sand and gravel aquifer,
Germany, was carried out by a dual isotope method of measuring both the delta(15)N
and delta(18)O in NO3-. Samples were prepared by an anion exchange resin method
(Silva et al., J. Hydrol. 228 (2000) 22) with a modification to the AgNO3-drying process
from a freeze-drying to an oven-drying method. The occurrence of denitrification in the
aquifer was confirmed by comparing the reduction of dissolved oxygen, dissolved organic
carbon and NO3- concentrations with the dual isotope signatures. High nitrate
concentrations were associated with low delta(15)N and delta(18)O values, and vice
versa. The denitrification accords with a Rayleigh equation with calculated enrichment
factors of epsilon = -13.62parts per thousand for delta(15)N and epsilon = -9.80parts per
thousand for delta(18)O. The slope of the straight-line relationship between the
delta(15)N and delta(18)O data demonstrated that the enrichment of the heavy nitrogen
isotope was higher by a factor of 1.3 compared with the heavy oxygen isotope. It is
concluded that the identification of this factor is a useful means for confirming
denitrification in future groundwater studies. (C) 2003 Elsevier Science Ltd. All rights

Abstract: Elevated sulfate concentrations and their heterogeneous distribution in the
drinking water catchment area Torgau-Mockritz (Germany) were investigated by means
of multiple isotope signatures such as delta(34)S, delta(18)O-H2O, deltaD, tritium, and
Kr-85. delta(34)S values of the groundwater sulfate vary between -19...+ 37parts per
thousand CDT. No simple correlation exists between sulfate concentrations and
delta(34)S. Superimposition of different sulfur sources and mobilization processes
combined with a complicated groundwater movement create a complex distribution
pattern. The oxidation of reduced sedimentary sulfur has to be regarded as a main source
of dissolved sulfate at least regionally. Tritium and C-14 data revealed that old
groundwater can be excluded as source for high sulfate contents. Correlated temporal
variations in the concentrations of tritium and sulfate are observed in deeper sampling
positions. Highly variable delta(18)O and deltaD, as detected in parts of the catchment
area, indicate local influences of surface water infiltration into the aquifer. The spatial
distribution of isotope signatures enables the identification of zones with descending
younger water or hindered groundwater movement and hence provides useful hints for
flow modeling.

Abstract: Wells placed next to surface-water bodies to induce infiltration have come
under scrutiny because of the presence of the potential pathogens in surface water.
Removal of pathogens and other contaminants by bank filtration is assumed, but
regulatory agencies question the effectiveness of this process. To investigate transport
processes of biological constituents, advective groundwater traveltimes to production
wells under the influence of surface water need to be established first to determine
appropriate water-quality sampling schedules.
This paper presents the results of a study of bank filtration at a well field in southwestern
Ohio. Field parameters such as water level, specific conductance, and water temperature
were measured at least hourly at a streamflow gaging station and at five monitoring wells
each at two separate sites, corresponding to two nearby production wells. Water-quality
samples also were collected in all wells and the streamflow gaging station.
Specific conductance is directly related to concentration of chloride, a chemically
conservative constituent. Cross-correlation methods were used to determine the average
traveltime from the river to the monitoring wells. Traveltimes based on specific
conductance ranged from approximately 20 h to 10 days at one site and 5 days to 3
months at the other site. Calculated groundwater flow velocities ranged from 2.1 x 10(-3)
to 6.0 x 10(-3) cm/s and 3.5 x 10(-4) to 7.1 x 10(-4) cm/s at the two sites. Data
collected when a production well is continuously pumping reveal shorter and more
consistent traveltimes than when the same well is pumped intermittently. (C) 2002
