coliform are indicator organisms which are used to indicate the
presence of pathogens.

The water quality parameters for Lemon Reservoir and the

Florida mainstem fall into five categories: physical and biolog-

ical, inorganic, metals, organic, and uranium, and are ill us-

trated in Table 5.3.

The Environmental Protection Agency I s data base "STORET"
provided water quality data for the "Florida River Below Lemon
Reservoir" sampling station, but no data was available for the
reservoir itself. The data included historic and recent results
of both grab and composite samples. The data were presented in
two STORET files: (al PGM-INVENT and (bl PGM=ALL PARM. The
PFM=INVENT file is a summary of all of the statistics for all of
the parameters and provides a composite average of all of the
data. The PGM=PARM file describes the actual sample values for
each of the parameters and contains the majority of the data upon
which the PGM=INVENT file was based.

When applicable, the majority of the water quality standards
were met (e.g. chlorine residual and sulfur as hydrogen sulfide
did not apply) However, for three of the parameters--lead,
mercury and silver--the summary data appears to exceed the water
quali ty standards for Class 2 Recreation. After examining the
actual sample values (these values are the basis for the summary
datal, it became evident that many of the values which were
presented as being "less than" a certain value, were actually
integrated into the summary table as that value. (Those values
which were less than 5 were carried over to the summary table as
5). Table 5.4 presents an overview of the STORET data for these
three parameters in question and is organized according to
numeric standard, the summary data and the actual sample values.
