What to test for in Stafford 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:
- The Kansas Department of Health and Environment (KDHE) and K-State Research and Extension recommend annual water tests for coliform bacteria and nitrate. Testing for common impurities and nuisance contaminants is recommended every one to three years, with possible extra testing after chemical spills or flooding. source
- K-State lists situations that suggest special or more frequent bacteria tests: flooding near the well, a well near confined livestock pens, a change in water color, turbidity, odor or taste, recurring digestive illness in people or animals, and after repair of the well or plumbing. source
- K-State's well maintenance guide recommends testing private wells annually at a minimum; annual maintenance should include testing for coliform bacteria, nitrate, pH and total dissolved solids. source
Arsenic. USGS estimates that about 111 people using private wells in Stafford County had arsenic above 10 µg/L, EPA's limit for public water (2010 base year; 95% range 88 to 141). 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 Stafford County in Zone 2: moderate potential (average indoor radon may be between 2 and 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.
