A private well report should be read as evidence about a particular sample and set of tests. It is not a permanent guarantee of water quality or a complete assessment of the well's equipment and performance. Before buying, establish the actual supply and gather the records needed to ask precise questions.
What should the water-quality review include?
MassDEP recommends that prospective buyers test private well water before purchase. Confirm the address, sample point, date, laboratory and substances included in the test. A report for water after treatment answers a different question from a sample taken before treatment. Ask the local board of health and qualified professionals about the testing appropriate to the property and current requirements. Clear appearance or a seller's long experience with the well does not replace laboratory evidence.
Which equipment questions remain outside the lab report?
Identify the well, pump, pressure equipment, storage and treatment system, along with available installation and service records. Ask about documented performance, maintenance tasks and recurring consumables. A water-quality result does not establish the condition of every component or the reliability of supply under the household's intended use. Seek professional evaluation where those questions are unresolved. Keep equipment and treatment costs visible separately from the purchase price and from any general allowance for household utilities.
How should town-level water records be used?
The community-water entries below describe systems recorded within selected municipalities. They do not establish service at every address or prove that a property with a private well can connect later. Confirm actual serviceability with the provider if connection is part of the plan. Wastewater disposal also needs its own investigation. A complete review distinguishes source, quality, equipment, treatment and maintenance so a positive answer in one category is not mistaken for a complete answer about the property's water.

What These Columns Mean
- Town
- Municipality; follow its record below for the full data and address check.
- Community Water Recorded
- Whether a community water system is recorded for the municipality. A yes does not show that a particular parcel is connected or eligible for connection; confirm with the provider.
- Sewer Recorded
- Whether a sewer system is recorded for the municipality. Town-level presence does not establish street coverage, a private connection, available capacity or connection cost.
- Median Lot Acres
- Median recorded single-family parcel acreage. Lot area is not a measure of buildable, dry or accessible land and does not establish a surveyed boundary.

What should you check next?
- Match the report to the actual property, sample location, laboratory, date and tested substances.
- Obtain equipment and treatment records and investigate performance and maintenance questions separately.
- Confirm any proposed public connection directly and review wastewater arrangements as a separate property system.
Keep the address, document date and source alongside each answer. If records disagree, identify which period and property each describes before treating the difference as a change. A missing result leaves a question open; it does not establish that a property has no problem or no cost.
