Frequently Asked Questions

What should I test my well water for in Pennsylvania?

PA DEP recommends annual testing for coliform bacteria, nitrates, and pH at minimum. Additional recommended tests include lead, iron, manganese, hardness, and total dissolved solids. If near gas drilling or mining, test for methane and heavy metals. Radon testing is recommended in some PA counties.

How often should well water be tested?

Test annually for bacteria and nitrates. Test every 3-5 years for a broader panel. Test immediately if you notice changes in taste, color, or odor, after flooding, after well work, or if anyone in the household has unexplained illness. Baseline testing is recommended when you move into a home.

Where can I get my well water tested in Pennsylvania?

Pennsylvania has PA DEP-accredited laboratories throughout the state. Your county Penn State Extension office can provide sampling kits and recommend local labs. Some well service companies also offer water testing as part of their services.

How much does well water testing cost in Pennsylvania?

Basic bacterial and nitrate testing costs $50-$100. A standard panel (bacteria, nitrates, pH, iron, manganese, hardness) costs $100-$200. Comprehensive testing including metals, VOCs, and radon costs $300-$500. Penn State Extension often offers discounted testing programs.
