Measured E. coli concentrations in final effluent from the discharge pipe of the Limestone Branch Tributary Wastewater Treatment Facility starting June 2021. The Virginia DEQ facility discharge permit limit of 126 CFU is exceeded in 15 out of 28 sampling events, with two of these events having values 192 times the permit limit.
Loudoun Wildlife is grateful to Friends of the Shenandoah River for providing the baseline E. coli data from 2021 and February 2022 for this project.
