The E. coli results are in for the water samples that I collected and tested yesterday for the FOSR’s summer E. coli testing program. It was more than sediment that was being carried downstream in Manassas Run. The E. coli level in Manassas Run above the confluence with the Shenandoah River at the bridge on Morgan Ford Road was 1,732.9 MPN of E. coli CFU per 100mL of water sample (FW-36). The E. coli level in the Shenandoah River along the banks downstream of the confluence with Manassas Run was 920.8 (FW-35). I also collected a water sample by wading out into the river away from the disturbance. The E. coli level in this sample was 35.9, Shenandoah River mid-stream (FW-35 Mid).
