2026-02-18 · 5 min read · Guide
Average Testing Costs
Basic bacteria and nitrate test: $25-$50. Standard panel (bacteria, nitrate, pH, hardness, iron, manganese): $75-$150. Comprehensive panel (adding arsenic, lead, radon, VOCs): $200-$400. PFAS testing: $200-$350 standalone. Full water quality survey: $500-$800.
State Programs
Many states offer subsidized or free testing: Maine: CDC offers comprehensive testing packages. Connecticut: Requires testing at property transfer. New Jersey: Mandatory testing for multiple contaminants at sale. Virginia: Free bacteria testing through health departments. Minnesota: Free arsenic testing through MDH.
Where to Test
State-certified labs provide the most reliable results. University extension programs (Penn State, UMass, Rutgers) often offer affordable testing. Private labs may be faster but verify certification. Avoid relying solely on home test kits for decision-making.
How to Save
Group testing with neighbors can reduce per-sample costs. Some labs offer package discounts. Check if your state or county offers free or reduced-cost testing programs, especially for new well owners or in areas with known contamination.
