Pulaski County River Testing Results

This information is given to the public by Pulaski County Health Center (PCHC) for public health information purposes. PCHC is conducting sampling in order to inform citizens of recreational water conditions. The information given will allow citizens to make informed decisions on when they feel water conditions are favorable for bodily contact and recreational activity. PCHC will be sampling from eight (8) different locations within Pulaski County to gain a good perspective of overall water quality. Public notification of sewage lagoon outfall has now been posted at the point source location to make waterway users aware and recommended not to swim near posted signs. Although the outfall and it's treatment center have been updated and reconstructed.

Environmental Protection Agency's (EPA) established water quality criteria for monitoring bacteria, which states no single water sample should have an E. coli count that exceeds 235 CFU's (colony forming units) per 100 mL of water. (To determine the weeks testing numbers look in the column labelled MPN/100ml and compare to EPA number)


If river waters are rising after a rain it is best not to swim in that body of water due to the higher prevalence of bacteria and greater chance of accidental drowning.  Please be very careful around all bodies of water when flooding is occurring.


Be safe and enjoy Pulaski County and it's beautiful waterways!
