MountainTrue, a leading local environmental group, is encouraging the public to use the Swim Guide app before heading out onto the water to ensure healthy and happy summer weekends. MountainTrue is the home of the Green Riverkeeper, Broad Riverkeeper, French Broad Riverkeeper, Watauga Riverkeeper, and a Western Clean Water Team based in Murphy, North Carolina, who are dedicated to protecting the waters of the Southern Blue Ridge Mountains. 

Each week between Memorial and Labor Day weekends, MountainTrue’s staff and volunteers collect and analyze water samples from 96 popular recreation spots across western North Carolina and Towns and Union Counties in northern Georgia. These samples are processed and analyzed, and the results are posted on the Swim Guide website (theswimguide.org) and the smartphone app in time for the weekend. This resource-intensive program is made possible by donations from MountainTrue’s members and the generosity of local businesses and organizations that sponsor one or more Swim Guide recreation sites.  

In the Broad and Green River Basins, our Swim Guide Sponsors include Green River Cove Tubing, H2O Dreams, Green River Adventures, Shelby Women for Progress, Rutherford Outdoor Coalition, and Robin Brackett State Farm Insurance. 

1. coli bacteria makes its way into our rivers and streams from sewer and septic leaks and in stormwater runoff — especially runoff from poorly managed animal agricultural operations. E. coli is an indicator of the presence of more harmful microbes, such as Cryptosporidium, Giardia, Shigella, and Norovirus. Contact or consumption of contaminated water can lead to gastrointestinal illness, skin infections, respiratory issues, and other health problems.

“We do testing mid-week, analyze the results, and get them to the public in time for the weekend,” explains Green Riverkeeper Erica Shanks. “These tests are a snapshot in time. If we test on a Wednesday after a dry spell, our results usually look pretty good, but conditions can change rapidly following heavy rains when stormwater runoff brings pollution into our waterways. Take extra precautions after hard rains and do not ingest or expose any open cuts or abrasions to water.”

The Swim Guide lists each testing site as either passing or failing based on the U.S. Environmental Protection Agency’s 2012 Recreational Water Quality Criteria for primary contact of 126 CFU/100 mL. Waterways located in remote areas or near protected public lands with minimal agricultural and industrial pollution sources tend to be the cleanest and less impacted by stormwater runoff. Areas closer to development and polluting agricultural practices face greater risks, especially after heavy rainstorms that result in increased water runoff. 

While the primary purpose of the Swim Guide is to inform the public about where it’s safe to swim, MountainTrue also uses the data collected to solve water quality problems, inform its advocacy, and push for science-based policy solutions aimed at protecting the health of local communities and supporting the river recreation economy.

“Our rivers are a really important cultural, recreational, and economic resource for our region,” says Broad Riverkeeper David Caldwell. “If we want to clean up the dirtiest rivers and protect the cleanest ones, we need policymakers to act to increase riparian buffers, encourage better building and farming practices and invest in upgrading aging sewer infrastructure to meet current and future needs.”
