Data was collected as part of basin wide synoptic grab sample events in May, July and September. All three events includes the following parameters: Temperature, pH, dissolved oxygen, conductivity, and pathogens. Pathogen anaylsis at all locations included results for e. coli as well as total coliform and fecal coliform at varying sites. Field observations were generally made for stream flow, turbidity, and rainfall. In addition, there were additional parameter selected based on seasonal priority. These are detailed below.

The spring event occurred on April 29th and May 1st with a total of 104 sites reporting.  Of these sites 41 were found to be exceeding the Kentucky surface water standard of 240 CFU/100ml for e. coli. Additionally, all sites were analyzed for triazine herbicide and estradiol 17B. A total of 21 sites indicated the presence of triazine.  A total of 37 sites indicated the presence of estradiol 17B.

The summer event occured on July 20th and 22th with a total of 110 sites reporting. Of these sites 51 were found to be exceeding the Kentucky surface water standard of 240 CFU/100ml for e. coli.  Additionally,42 sites were analyzed for the presence of  estradiol 17B. A total of 27 sites tested positive for the presence of this compound. The complete data set for this event can be viewed at this link.

The fall event occured on September 14th and 16th with a total of 84 sites reporting. Of these sites 31 were found to be exceeding the Kentucky surface water standard of 240 CFU/100ml for e. coli. Also, 24 sites were resampled for estradiol 17B, with a total of 12 testing positive for this compound. Additionally, all sites were analyzed as part of a low flow sample suite that included: alkalinity, chlorides, nitrate(NO3), nitrate-N(NO3-N), sulfate, total nitrogen, total recoverable phosporus, and total suspended solids.
