Request Tap Water Test Results - Boston City Guidance

Utilities and Infrastructure Massachusetts 3 Minutes Read ยท published February 07, 2026 Flag of Massachusetts

Residents of Boston, Massachusetts who want official tap water quality test results can obtain information from the regional supplier and state regulators and request targeted sampling through local channels. This guide explains where the official water quality reports live online, who enforces drinking-water rules, how to request results or a follow-up sample, and what to expect from enforcement or appeals.

Where official test results are published

Boston receives its treated drinking water from the Massachusetts Water Resources Authority (MWRA). MWRA publishes water quality reports and monitoring data online; for local compliance and enforcement, the Massachusetts Department of Environmental Protection (MassDEP) oversees public water systems and enforcement of drinking-water standards. For specific sampling or system-level test results, contact the water supplier listed on your bill or the MWRA page below. MWRA Water Quality[1] and the state's drinking-water pages contain program and enforcement information. MassDEP Drinking Water[2]

Requesting your tap water test results online or by request

Typical paths to obtain results:

  • Check the MWRA Consumer Confidence Report and online water-quality pages for system-wide results and sample schedules.
  • Contact your local water utility or the MWRA customer service to request system- or address-specific sampling records; ask whether the utility posts laboratory reports or will provide them on request.
  • If you need a private tap sample, hire a state-certified laboratory and request a chain-of-custody form and a copy of the final lab report.
Start with the MWRA system reports to see routine monitoring before requesting a targeted sample.

Penalties & Enforcement

Enforcement for drinking-water violations affecting Boston residents is handled by MassDEP for public water systems and by the MWRA for system operations, with federal oversight by the U.S. EPA for federal Safe Drinking Water Act violations. Specific monetary fines, escalation schedules, and administrative penalties vary by violation and are set out in state and federal enforcement policies.

  • Fine amounts: not specified on the cited page.
  • Escalation for repeat or continuing offences: not specified on the cited page.
  • Non-monetary sanctions: orders to correct, mandatory sampling, system operations restrictions, and referral to state or federal enforcement are used; specific remedies depend on the finding on the cited pages.
  • Enforcer and inspection pathways: MassDEP enforces drinking-water regulations; MWRA operates and monitors the regional supply. To file a complaint or request inspection, contact MassDEP or MWRA through their official pages listed below.
  • Appeals/review: procedures and time limits for appeals of enforcement actions are governed by MassDEP administrative rules; specific time limits are not specified on the cited page.
If you receive an enforcement order, follow the corrective schedule and ask the issuing agency about appeal deadlines immediately.

Applications & Forms

Public-system routine reports (Consumer Confidence Reports) are published by MWRA; specific forms to request official utility sampling results are not consistently published on a single municipal page and may require a direct request to the water supplier or MassDEP. If you seek an independent sample, use a state-certified laboratory and its chain-of-custody form. For system-level enforcement or formal information requests, check MassDEP guidance and MWRA contact pages for submission instructions.[1]

  1. Locate the MWRA water quality and Consumer Confidence Report online to review system monitoring results.
  2. Contact MWRA or your local water utility to ask for lab reports tied to recent samples at your address or neighborhood.
  3. If a specific contaminant concern exists, arrange for certified-laboratory sampling and request the chain-of-custody and final report.
