Knowledge of the quality of North Alabama’s rivers and streams is important because of the impact that it has on human and aquatic health.
Integrated use of in-stream water quality data and modeling will likely improve the assessment and management of streams at the watershed scale.
Cont’d
•Historically, North Alabama has been plagued with environmental problems.
•According to the EPA Toxics Release Inventory,
Alabama is the sixth most polluted state in the nation.
•Four of Alabama’s river systems are rated in the top ten most threatened rivers in the country.
A large number of water bodies in North Alabama fail to attain water quality standards due to the presence of one or more pollutants.
Currently, there is a lack of water quality data to adequately address the status of water quality in North Alabama.
Even though significant progress has been achieved in stemming pollution from point sources, major challenges remain from non-point sources.
These challenges call for a focused effort to identify polluted waters for the purpose of developing TMDLs (Total Maximum Daily Loads) and implementing more effective BMPs (best management practices).
Cont’d
According to the Alabama Department of Environmental Management
(ADEM) agriculture causes about 40% of the non-point source pollution (NPS) problems in Alabama.
Major type of agriculture = row crop
-cotton
-corn
-soybean
Two major sources of agricultural pollution
-eroded sediment
-animal wastes
Streams and Rivers in Northern Alabama
• In 2002, the USGS found that concentrations of nitrogen and phosphorus in water samples obtained from Flint
River generally exceeded thresholds indicating eutropic potential.
• Input of dissolved and suspended chemicals from the
Flint River during storms influences water quality in the reach of the Tennessee River from which the City of Huntsville,
Alabama, withdraws about 40% of its drinking water .

µ-Trac 4200 Microbiological Analyzer
This compact impedance analyzer is user friendly and easy to operate, even by non-experts. The concept of 21 measuring places each one separately programmable in a dry block thermostat and administrated by a laptop computer is unchallenged in performance and possibilities. The µ-Trac reveals its strengths wherever microbiology is being performed on an absolutely minimum budget. The availability of pre-filled measurement cells eliminates the whole media preparation process. All hygiene-relevant microbiological parameters of production plants can be covered by this tiny genius in the simplest possible way.

Simulation model that links pollutants to aquatic life
Integrates fate & ecological effects
• fate & bioaccumulation of organics
•
• food web & ecotoxicological effects
• nutrient & eutrophication effects
• Predicts effects of multiple stressors
• nutrients, organic toxicants temperature, suspended sediment, flow etc…
Managers need to know:
• Which of several stressors is causing the impairment?
Will proposed pollution control strategy lead to restoration of desirable aquatic community, as well as to improved chemical water quality?
Will there be any unintended consequences?
How long will recovery take?

•
It is primarily agricultural and forested land in northern Alabama and south-central Tennessee (U.S.
Geological Survey, 2002).
•
Urban and residential land represent a small (less than 1%), but growing part of land use in the watershed, as residential growth from the City of
Huntsville continues to spread.
• The Flint River is an important recreational and scenic resource.
• Local agencies are conducting riparian restoration projects to protect and enhance habitat for the diverse aquatic life along the Flint River.
• Among the several threatened species of fish and aquatic invertebrates found in the basin are the slackwater darter , Tuscumbia darter , and southern cave fish .

AQUATOX can be used as tools for assessment of nutrient and sediment pollution. However, the
AQUATOX model has large number of parameters that need to be adjusted for model.
Measured data on discharge and other water quality parameters including NH3-N, TP, and TSS at multiple points in the watershed is critical for AQUATOX calibrations.
Dynamics of fish, types, and population varies over time due to change temperature, stream flow and availability of food.
The accuracy of the input parameters is critical for accurate model predictions.
It has great potential to estimate recovery time for fish or invertebrates after reducing pollutant loads.
