Well Water in Northampton County: What to Test and Why

Your well draws water from old limestone and dolostone rock buried deep underground. This rock is cracked and broken into many pieces, with water flowing through the cracks and empty spaces. The county sits on this same carbonate rock type that stretches across much of northeastern Pennsylvania.

Manganese, radon, and iron come straight from the rock itself. As groundwater sits in contact with these minerals over time, they dissolve into the water. Radon is a radioactive gas that forms naturally inside the rock and seeps into the water moving through the cracks. The rock here provides little protection from these natural contaminants.

Your water is extremely hard because of all the minerals dissolved from the limestone. You will see thick white crusty buildup on faucets, shower heads, and inside pipes and appliances. The high sodium and sulfate levels mean your water tastes salty or bitter, and these minerals will corrode pipes and damage water heaters over time.

Your well water in Northampton County has three contaminants that exceed EPA health standards: iron, manganese, and radon. Radon is a radioactive gas that comes from the bedrock beneath your area. Manganese and iron dissolve into your water as it moves through the ground. This is a serious situation that needs your attention.

Long-term exposure to radon in water increases your risk of lung cancer. Manganese can affect your brain and nervous system over many years. Iron won't hurt your health at these levels, but it stains your sinks, tubs, and laundry orange-brown and leaves rust-colored buildup. Your water is also extremely hard, which means white scale will coat your pipes and appliances. The sulfate and sodium levels are very high and give your water a salty taste.

Get your well tested by a state-certified lab right away. A basic bacteria and nitrate screen costs $50–100. A comprehensive metals panel costs $200–400 and should include radon, iron, and manganese. An aeration system can remove radon from your water, and a softener can help with hardness and some iron.
