Environmental Testing and Research Laboratories is a water testing laboratory in Leominster, and the first thing to know is a state action: in 2021, wbjournal.com reported that the Massachusetts Department of Environmental Protection had revoked its license. A 2024 Reddit poster wrote that they had read the lab lost its Massachusetts state license for providing false or inaccurate results back in 2021. A 2023 customer also noted that the lab was not certified by the state of Massachusetts as of 2021. The company says it has been in business 31 years. A recent customer who had been sent in circles by two separate filtration companies said that after testing and speaking with Nick, they got answers that helped them fix the problems they were having. A recent customer thanked Nick and Joshua for the time they spent going over their well water issues. A 2026 customer from New Hampshire said the lab director suspected their well cap was buried and told them to extend the well above ground level, replace the cap and have the well shocked. About 5 weeks later, that customer wrote, the water had no foul smell. A 2025 customer said they had used ETR for both water and air tests and that staff reviewed the results with them on the phone. A 2023 customer said yearly arsenic testing showed their arsenic filter was still good, after a filter company had said it was due to be replaced. A 2022 customer said they picked up sample bottles, dropped the sample back off and had results in 3 days at a reasonable cost.
“They recommended ETR labs for testing but I was googling reviews and saw that they lost their Massachusetts state license for providing false or inaccurate results back in 2021.”
“Environmental Testing and Research Laboratories, Inc., a water testing laboratory in Leominster, has had its license revoked by the Massachusetts Department of Environmental Protection, according to a Monday announcement from MassDEP.”
“The Massachusetts Department of Environmental Protection (“MDEP”) issued a November 29th news release stating that it had revoked the license of Environmental Testing and Research Laboratories, Inc. (“ETR”) of Leominster, Massachusetts.”
“The Massachusetts Department of Environmental Protection (MassDEP) has revoked the license of a water-testing laboratory after a state investigation determined that the company, Environmental Testing and Research Laboratories, Inc. (ETR) of Leominster, repeatedly failed to properly analyze private drinking water samples and report the test results in accordance with its certification and state regulations.”
Staff is amazing to deal with. Can’t say enough about this lab. We were finally able to get some good help and answers on our well water issues we were having. Big thank you to Nick and Joshua for the time they spent going over my situation.
Excellent experience with ETR Labs. The staff was professional, knowledgeable, and incredibly helpful throughout the entire process. They provided clear instructions, quick turnaround times, and detailed results that were easy to understand. It's obvious they take pride in their work and genuinely care about providing accurate, reliable testing. Will use them again for any testing needed.
This lab is incredible. I was being sent in circles by two separate filtration companies. After testing and speaking with Nick I finally got answers that not only made sense as he explained everything but helped me finally fix the problems we were having.
Great customer service. Extremely helpful!
Working with ETR Labs has been a complete upgrade from my past experiences with other laboratories. From day one, their team has been professional, responsive, and genuinely easy to work with. They consistently go out of their way to accommodate requests without the friction or delays I’ve dealt with elsewhere. The quality of their work is excellent. Reports are clear, well-organized, and easy to interpret without unnecessary complexity, which makes a real difference when you’re relying on accurate, timely information. Turnaround times have been consistently fast, allowing me to keep projects moving without delays. What stands out most is their customer service. The staff is friendly, knowledgeable, and always willing to take the time to answer questions or provide clarification when needed. It’s clear they value their clients and take pride in what they do. ETR Labs has become my go-to for all water testing needs, and I would confidently recommend them to anyone looking for reliable results and a smooth, professional experience.
