8. Clark’s Run 2


Measured E. coli concentrations in Clark’s Run 2 starting in February 2022. Between May and September 2022, the Virginia DEQ single sample recreational use threshold of 235 CFU is continuously exceeded at values up to 8 times the threshold.
Loudoun Wildlife is grateful to Friends of the Shenandoah River for providing the baseline E. coli data from February 2022 for this project.
