July Water Quality Results

On July 26th and 27th we collected water quality samples from seven of our nine sample sites. Two of the samples came back above the state standard for E.coli of 349/100mL.

Smith Branch and 12 Mile Creek had E. coli results above the state standard for contact recreation. High bacteria levels in these urban streams are usually associated with pollution from stormwater runoff, but there was no recorded rainfall in the days leading up to our sampling, which suggests there may be other sources of pollution in those watersheds that need to be investigated.

It is also important to note that these samples only represent a snapshot of the water quality conditions at a single point in time at a single location, and those conditions can change rapidly. It is likely that after the recent rains (and associated sewer spills) there are currently elevated bacteria levels in most local rivers and streams.

We were unable to sample the Congaree River and Broad River sites this cycle because of boat and access issues. We expect to be able to pick them up again next cycle.
