Join our summer pathogen-testing project!
Most people know it can be unsafe to drink unfiltered water out of a stream or lake, even if the water is visibly clear. This is true almost anywhere, including Adams County. Places where public swimming is encouraged are required to test the water to make sure it isn’t overly contaminated. But in Pennsylvania we have many waterways—more than 1,000 miles in Adams County alone—and most of them are not tested regularly.
The Watershed Alliance is launching a water-testing program aimed at this issue. We piloted the program in 2021, testing five sites. Thanks to a grant from the South Mountain Partnership, we’ll be expanding this testing program to 20–30 sites in 2022. Our plan is to inform the public about where our local waters may be contaminated, and we hope that our findings will inform future water-quality improvement efforts.
Here’s the background: Many common animal pathogens are invisible to the eye, but can cause sickness in humans, sometimes even death. Generally, these pathogens come from inside the guts of animals like humans, cows, deer, etc. They get into the water mainly through feces, or from dead animals.
The usual way people become infected with pathogens is by ingesting contaminated water. However, some pathogens can enter your bloodstream through cuts or sores on your skin. People often get infected swimming in a polluted river or lake, especially during warm months.
In September 2021, we tested five locations, five times each. At two of them we found average pathogen levels that fell within the state’s acceptable range for recreational use. These were at the Conewago Creek at the Conewago Creek Campground just northwest of Arendtsville, and Swamp Creek at the first trail crossing from Strawberry Hill Nature Center.
At the other three sites we tested, we found average pathogen levels that were unsafe for human recreation. These sites were at Toms Creek in Carroll Valley Park, the Conewago Creek fly fishing area along Narrows Road, and Middle Creek at Gordon Road.
Here’s how you can help: First of all, we need to identify 20–30 sites in Adams County where folks like to fish, wade, swim, or otherwise play in the water. And then we need to find and train volunteers who can help with sampling the water at these sites. We’ll be collecting five samples at each site within a 30-day period in summer. The samples will need to be labeled, kept cool, and promptly delivered to the Adams County Ag Center for transport to the testing lab.
Would you like to help measure the cleanliness of our waters? If you can suggest sampling sites and/or would like to help gather water samples for testing, please drop us a line.
If you’d like to provide funding so that we can test more than 20-30 sites, please visit our hompage to make a contribution. (Scroll down to the Donate button at the bottom of the page!)
We’d like to acknowledge our partners and funders for this project: We’re working with Adams County Trout Unlimited, Friends of Toms Creek, and the Adams County Conservation District.
This project was financed in part by a grant from the Community Conservation Partnerships Program, Environmental Stewardship Fund, under the administration of the Department of Conservation and Natural Resources, Bureau of Recreation and Conservation. The grant was awarded through the South Mountain Partnership, with management oversight by the Appalachian Trail Conservancy.
