Boston, MA water experts

Yes, Boston tap water is considered safe to drink and consistently ranks among the cleanest urban water supplies in the U.S. The Massachusetts Water Resources Authority (MWRA) conducts rigorous daily testing and complies with all EPA and Massachusetts Department of Environmental Protection standards.

For commercial properties, however, internal plumbing systems—especially in older buildings—can affect water quality by introducing contaminants like lead. Many Boston offices choose to install point-of-use filtration systems or provide bottled water to ensure the highest quality and taste for employees and guests.

Regular water testing and filtration can improve workplace health, reduce complaints, and help protect break room equipment like coffee machines and ice makers.

No, Boston’s water is naturally soft. Sourced from protected reservoirs in central Massachusetts, it contains low levels of calcium and magnesium, which are the primary minerals responsible for hard water.

Soft water offers several benefits to commercial properties:

• Less scale buildup in pipes, boilers, and HVAC systems
• Better performance from commercial dishwashers and water heaters
• Improved taste and clarity in beverages like coffee and tea

For Boston-area businesses, soft water translates to lower maintenance costs and longer appliance life.

As of the most recent reports, Boston tap water has *non-detectable or very low levels of PFAS (per- and polyfluoroalkyl substances), well below state and federal limits. The MWRA tests regularly for PFAS and publishes results to ensure transparency.

That said, PFAS are an emerging concern nationwide, and proactive businesses in industries like healthcare, education, and tech are beginning to install certified PFAS filters to reduce any potential long-term exposure for employees and visitors.

If you’re managing a commercial property and want to be proactive, consider a NSF-certified filter for PFAS reduction at water stations or break room sinks.

Boston tap water itself is free from lead because it is sourced from protected reservoirs and thoroughly treated to meet rigorous water quality standards. 

However, lead can sometimes be found in older plumbing systems, particularly in buildings constructed before 1986 when lead pipes were still common. 

Businesses, especially in older office buildings or historic properties, are encouraged to test their water regularly and consider installing point-of-use water filters to ensure that their water remains safe for employees and visitors.
