E. coli Testing Results for September 02, 2026

Cheers to river floats, hot dogs, and well-earned days off!

⚠️KNOW BEFORE YOU GO! This Week’s E. coli Testing Results Are Now Available

First and foremost: Thank you to those who donated to support this program. Your generosity keeps this program flowing, and we’re deeply grateful for every contribution.

Unfortunately we did not receive enough donations to continue testing every site over the next few weeks. However, we made it a priority to get you the data you need to make informed decisions about the river activities you want to enjoy this holiday weekend — so this week, we tested all 14 sitesAt the time and date tested, 2 sites exceeded the recommend E. coli level threshold of 235 CFU for primary recreational freshwater activities.

📍Main-stem Shenandoah River at Castleman’s Ferry, Route 7 bridge, public boat landing (Clarke County, VA)  – E. coli Level: 1119.9 CFU/100 mL 📈

📍Hawksbill Creek at the Luray-Hawksbill Greenway Town of Luray Pocket Park 🌳 Page County VA – E. coli Level: 344.8 CFU/100 mL 📈

💡 Why this matters: Bacteria spikes can happen quickly and unpredictably, especially during hot summer weather or following localized rainfall. 🌦️ Regularly checking site-specific data allows you to make informed decisions before you and your loved ones dive in, splash around, float down the river in your tubes, or paddle down our beautiful rivers and streams.

💙 🙏 Thanks to the Clarke County Board of Supervisors, Shenandoah Valley Electric Cooperative, CoBank, The Downstream Project, and our supporters, we can still test 6 sites on the Main Stem and South Fork. Donate to help us test all 14.
