What to test for in Pendleton County
Private wells are not regulated like public water: EPA advises owners to test their well every year for total coliform bacteria, nitrates, total dissolved solids and pH. Your state's own schedule:
- West Virginia's Office of Laboratory Services (OLS) advises testing at least once a year for coliform bacteria, nitrate and sodium, best in spring and summer after rainy periods, and again after repairing or replacing parts of the well. As an initial set of tests to check common issues, it lists total coliform, regulated metals, secondary metals and combined nitrate + nitrite. source
- The WV Department of Environmental Protection's well fact sheet says to test your water annually for total coliform bacteria, nitrates, pH, total dissolved solids and lead, and to test for fertilizer and pesticide contamination based on surrounding land uses. source
Arsenic. USGS estimates that about 231 people using private wells in Pendleton County had arsenic above 10 µg/L, EPA's limit for public water (2010 base year; 95% range 108 to 451). USGS describes this kind of estimate as useful "for broad screening of the population at risk", so it says nothing certain about any one well. Arsenic has no taste or smell: test for it by name.
Radon. EPA puts Pendleton County in Zone 1: highest potential (average indoor radon may be greater than 4 pCi/L). That map is about radon in indoor air, and EPA says it should not be used to decide whether an individual home needs testing. If radon is found in your air and you have a well, EPA suggests testing the water too: see radon in well water.
For anything specific to your home (farms nearby, old plumbing, a new baby, a smell or stain), use the which-tests checklist. When the results arrive, check your numbers against EPA's limits.
