We’ve been providing testing services for homeowners, real estate agents, home inspectors, hospitals, mortgage lenders, well drillers and other professionals since 1995. We maintain a state-of-the-art laboratory in Leominster, Massachusetts. Our lab is better equipped than most state or local water authorities, just so we can provide accurate test results you can trust.

Our extensive investment in laboratory equipment means that we can provide an extremely wide range of tests. The list of equipment in our lab includes two scanning electron microscopes and one nuclear magnetic resonance machine. Very few labs in our state are equipped with these devices, and fewer still provide testing for private clients. With this equipment, we can detect and identify bacteria, fungi and even protozoa in our clients’ water supplies.
Every device in our lab is calibrated in compliance with the manufacturer’s instructions at the beginning of the testing day and is recalibrated as needed during the day. We continually upgrade and invest in new equipment to keep our lab at the highest level of accuracy.
Excellent Customer Satisfaction
We are honored to have more than 370 reviews by verified customers on Angi (formerly Angie’s List) who gave us our rating of 4.8 out of 5.0. This is a typical response received from our customers:
As a first-time homebuyer, I am learning a lot of things for the first time and have many questions. When I had some results I didn’t understand, Nick spent a long time walking me through the results and was patient with my questions. After I had the seller shock the well, I had more questions after a second test was done with a different lab. Nick spent a long time explaining results, potential problems and if needed, possible remediations for problems. I cannot recommend Nick enough!
Our job is only done when you know exactly what steps to take to ensure healthy water for your family!
