Well Water in Shenandoah County: What to Test and Why

Groundwater in Shenandoah County contains radon, manganese, and arsenic that well owners should know about. These contaminants are present at levels high enough to exceed EPA health standards, which means they need attention.

The limestone and carbonate rock underneath this county naturally contains manganese and arsenic. Radon comes from the decay of uranium in the bedrock. Nitrite and sulfate can enter groundwater from agricultural land and septic systems on the surface, which seep down into the aquifer below.

Groundwater in this county is moderately hard, driven by calcium and magnesium released from the limestone bedrock as water moves through it. This hardness is typical of wells throughout Shenandoah County because the carbonate rock dissolves slowly and steadily into the water passing through it.

Several contaminants show up above EPA health standards in wells around Shenandoah County. Arsenic, radon, nitrite, and manganese can cause serious health problems with long-term exposure. Arsenic increases cancer risk and can damage organs. Radon is a radioactive gas that raises lung cancer risk. Nitrite and manganese affect how your blood carries oxygen and can harm children and people with certain health conditions.

The moderately hard water in county wells creates some annoying household issues. You might see white buildup on faucets and shower heads, or notice your soap doesn't work as well as it should. Hard water can make your skin feel dry and your hair feel sticky. Over time, mineral buildup in water heaters and dishwashers can shorten how long these appliances last.

We recommend testing your well water, since every well is different and yours could have much higher or lower levels than what is common here. Testing is the only way to know what is actually in your water so you can treat it properly. A comprehensive test for metals and minerals runs between two hundred and four hundred dollars. Treatment options like reverse osmosis systems or activated carbon filters can address multiple concerns depending on what your water contains.
