Our latest E. coli testing from July 23 reveals a mixed picture across the Shenandoah River and its tributaries. While most sites were within EPA guidelines for recreation, a few locations—like Castleman’s Ferry (E. coli MPN: 365.4) and Hawksbill Creek (E. coli MPN: 579.4)—still show elevated bacteria levels that exceed EPA guidelines and call for caution. Before you swim, fish, or paddle, check the data.

Why It Matters.
E. coli levels can spike quickly due to rain, runoff, or other environmental factors, posing health risks—especially for children and vulnerable individuals. That’s why Friends of the Shenandoah River conducts routine monitoring at public access points and shares timely results. With your support, we can continue testing, informing, and protecting our waterways all summer long.
