This table contains records where there was a problem with analysis of compounds found in the
CHEM and TRACE tables. Usually the values are below detection limits of the equipment. In the
table are two fields for each compound: the value (if any) and a text ‘alpha’ field showing the flag
associated with each record (“<”, “>”, “below detection”, etc). The table has these pairs for Ag, Al,

Thus, bibliographic references can be concatenated for any record in the CHEM table.
i
Based on assumption that some springs or wells will have temperature sampled without any chem. data
that would be contained in the chem table. Makes for duplicate location of temperature data
ii
Original latitude and longitude of a record is maintained because we moved some locations around in the
SITE table which we think are better, but we leave the original location here in case we were mistaken.
iii
Many fields in the CHEM table contain multiple ways a measurement was sampled. For example, pH
was potentially sampled both in the field and/or in the lab. The table thus can include multiple fields ‘pH
Field’, ‘pH Lab’, or ‘pH Unknown’ if the method was not specified. This data can also be found in the
CHEMMORE table keyed to the CHEM table in a one-to-many relationship, with two fields per
measurement: “Type” (such as ‘field’, ‘lab’, ‘unknown’, etc.) and “Item” (such as pH, eH, etc.). Yes, this
is in violation of database normalization rules, but the data were put in two ways to determine which
worked best, with the idea that one way would eventually be removed.
iv
Yes, this could have been a calculated field
