Mineral County, NV
These figures come from wells tested in Mineral County, NV, not from any one well.
- Manganese is common in wells in Mineral County, NV (8 of 22 tested wells were over that level), so it's worth testing for.
- Sulfate is common in wells in Mineral County, NV (28 of 48 tested wells were over that level), so it's worth testing for.
- Iron is not common in wells in Mineral County, NV (2 of 22 tested wells were over). Only a test tells you about your own well.
- Wells in Mineral County, NV are typically moderately hard (38 wells tested).
- Only a test of your own well tells you about your water.
What to test for
Start with the four this site covers:
- manganese (common in wells here)
- sulfate (common in wells here)
- iron
- hardness
Most well owners also test for these. We point to the source and don't interpret the results.
- arsenic: occurs naturally in groundwater in many regions. USGS: arsenic and drinking water
- nitrate: common near farmland and septic systems. EPA: private drinking water wells
- total coliform bacteria: the standard yearly well check. EPA: private drinking water wells
- lead and copper: from household plumbing, especially when pH is below 6.5. EPA: lead in drinking water
- PFAS: several states run private-well sampling programs. EPA: PFAS
- a certified lab: states certify labs and some run their own private-well programs. Nevada's certified-lab list (from your state drinking-water program)
