Whether you are buying, selling, refinancing, or simply want confidence in your family’s drinking water, ProVerde Environmental provides reliable private-well testing with clear, easy-to-understand results.

Private wells are not monitored like public water systems. Many contaminants have no taste, odor, or color, so testing is the best way to understand what is in your water.

Selling or Buying a Home With a Private Well?

For a Massachusetts real-estate transaction, contact the local Board of Health first. Private-well requirements are established locally, so required testing, sample-collection procedures, approved laboratories, and the age of acceptable results can vary by city or town.

MassDEP does not currently regulate private wells; local Boards of Health or health departments do. However, many communities use or adapt MassDEP’s model private-well regulation and water-testing recommendations.

Testing early can help you:

Avoid last-minute surprises and potential closing delays
Meet buyer, lender, and local Board of Health requirements
Give buyers clear documentation about the home’s water supply
Allow time to evaluate treatment options if results identify a concern
Keep your sale moving with fast, reliable testing and reporting

Before ordering a real-estate well-water test: Confirm the required test panel, sampling instructions, approved laboratory requirements, and acceptable test-result timeframe with the property’s local Board of Health.

Plan Ahead for Future Sales

Massachusetts is considering legislation that could authorize MassDEP to establish statewide private-well water-quality standards and testing requirements. These proposals have not become law, and the final requirements—if legislation passes—would be developed by MassDEP through a future regulatory process.

For homeowners in towns with limited current testing requirements, a more complete test can be a smart way to prepare for future expectations. Testing beyond today’s minimum local requirement can help document water quality, identify concerns early, and provide useful records when it is time to sell.

For the most complete picture of your water quality, consider testing that follows MassDEP’s current recommended private-well test categories, even when every item is not required locally.

What May Be Tested?

Your local Board of Health, lender, buyer, or real-estate professional may request one or more of the following tests:

Bacteria: Including total coliform and E. coli, which may indicate contamination from surface water, septic systems, or other sources
Nitrate and nitrite: Often associated with septic systems, fertilizers, and runoff
Metals and general chemistry: Such as arsenic, lead, copper, iron, manganese, sodium, pH, hardness, chloride, and fluoride
PFAS6: A group of “forever chemicals” included in MassDEP’s model Board of Health regulation and recommended private-well testing guidance
VOCs: Chemicals associated with gasoline, solvents, fuel spills, and industrial activity
Pesticides:
Radon: Particularly important for bedrock wells because naturally occurring radioactive materials can be present in groundwater
Naturally occurring radioactive materials: Gross alpha, Uranium and radium: Added when appropriate based on initial results from Radon, or from local previous house results, well type, or property history.

MassDEP recommends initial testing for these common private-well concerns and, for many parameters, repeat testing at least every 10 years. Bacteria and nitrate/nitrite should generally be checked annually. Local requirements may be different.

Why Test for Peace of Mind?

Well-water quality can change over time. Contamination can come from natural bedrock conditions, septic systems, nearby fuel tanks or spills, agricultural or industrial chemicals, flooding, and other nearby land uses.

Regular testing can help you:

Protect children, older adults, and other vulnerable household members
Detect invisible concerns before they create a larger health or treatment issue
Make informed decisions about filtration, treatment, or follow-up testing
Maintain useful records for future buyers, lenders, or property transactions
