May Water Quality Results

The main story for this round of sampling... RAIN.

On Monday, May 22nd and Thursday, May 25th we collected water quality samples at our 10 river and stream sites. The results for 7 of those samples were above the state standard for E.coli of 349/100mL, meaning the water may not be safe for contact recreation.

Between May 21st and May 25th the Midlands received between 2 to 5 inches of rain. The resulting stormwater runoff is the likely cause of the high bacteria levels in the six urban streams we sample as well as the Broad River. Once again, it is important to remember that bacteria levels usually spike in the 24-48 hours after a rain event and river users should consider past weather when making river recreation decisions. The Saluda and Congaree River samples were all below the state standard. On Thursday SCE&G was releasing around 10,000 cfs into the Lower Saluda, which likely had a significant dilution effect on pollution in the river.
