Welcome to ETR Laboratories

ETR Labs has been in the environmental testing business since 1995. We are a Central Massachusetts based, full service laboratory, specializing in the analysis of private drinking water. Our facility has serviced thousands of clients across North America and beyond.

There are essentially three market segments we serve. These include industrial companies large and small analyzing everything from process water to plastics, air samples to unknown analysis, dairy to particle analysis.  The second market segment is those individuals and businesses that own private water wells.  The third market segment is those businesses (Home Inspectors, Real Estate Agencies, mortgage lenders, Filtration Companies, well drillers and pump installers) which serve the private well owner.

Outstanding service and quality has made ETR Laboratories nationally recognized . We combine professional staff with state of the art equipment to provide our clients with fast results using the most up to date testing methods. We offer a wide range of testing options at reasonable prices that will address any concern or environmental issue that could affect your water.

Confidentiality is one of the most important elements of our business.  We will never share results of any work we do for a client, business, academic or individual unless our client specifically directs us to do so.  Our work on your behalf is for your benefit and yours alone.

We can provide you with a free sample collection kit. If that is not practical in your situation, call the lab for ideas on how to provide a suitable sample using other options.  You just send us back a water sample in the enclosed container. Results for most tests are completed within two business days. Reports can be emailed, faxed or mailed to you. Our goal is to provide you and your family the assurance and peace of mind that your water is safe, clean and healthy.

Sound analytic protocols are at the heart of what we do everyday. We thrive on a spirit of innovation and leadership, which are the essential elements of our laboratory’s continued success in meeting the needs of those who place their trust in us. We realize the importance of our test results and the impact they have on our client’s well being. Our philosophy is:

“Quality Water and Good Health go hand in hand”.
