The E. coli levels at all the River sites and Manassas Run (FW36, Warren County VA) tested were below the EPA’s recommended “do not exceed” threshold of 235 CFU of E. coli bacteria per 100mL of water sample.
However, Hawksbill Creek showed a significant increase, with a measurement of 1119.9 MPN E. coli CFU/100mL. This is approximately five times higher than both last week’s result and the EPA’s threshold for issuing early alerts to freshwater recreators.
These results provide a snapshot of the E. coli bacteria concentrations at the designated sites on the date, time, and under the conditions that the water samples were collected.
