Overview: Pennsylvania Well Water Rules
Pennsylvania does not mandate well water testing at point of sale by state law. Testing is required by federal loan programs (FHA/VA/USDA) and is increasingly standard for conventional loans. The PA DEP administers the accreditation of testing laboratories, and many counties offer cost-assistance programs for private well testing.
What Must Be Tested in Pennsylvania
| Parameter | Standard | Requirement |
|---|---|---|
| Coliform bacteria | Absent | Loan-required |
| Nitrate | ≤10 mg/L | Loan-required |
| Lead | ≤0.015 mg/L | Loan-required |
| pH | 6.5–8.5 | Loan-required |
| Comprehensive baseline | Full panel | Recommended for new owners |
Finding a State-Certified Lab in Pennsylvania
Pennsylvania requires testing through a state-certified laboratory. To find a lab:
- Contact your county health department — many maintain a local lab referral list
- Search the PA DEP Safe Drinking Water Program website for a list of certified labs
- Use our national certified lab finder guide for resources
Do not use a DIY kit or an uncertified online mail-in service for loan transactions or state-required testing. Results must come from a PA DEP-accredited laboratory (NELAP certified).

I’m buying with cash in Pennsylvania — do I need a well water test?
For a cash purchase in Pennsylvania, there is no legal requirement in most situations. However, conducting your own water quality test is strongly recommended. A basic certified lab test costs $100–$200 and is far less expensive than discovering contamination after closing.
How much does well water testing cost in Pennsylvania?
A basic certified lab panel in Pennsylvania (coliform + nitrates + pH) typically costs $75–$150. A comprehensive panel meeting loan requirements runs $150–$350. Some county health departments offer subsidized testing programs — call your county health office to check. See our full cost guide for more detail.
