Our Story

CWM Environmental was originally founded in 1985 in Kittanning Pa, with the purpose of handling the water analysis requirements of the mining industry. David Kohl the current owner and president of CWM, was part of the small group from W.D. Mohney & Associates who founded and worked in the lab. In 1987 Dave left CWM to join Abbott Labs, but returned in 1994 and purchased the 3 person lab. CWM functioned as small lab focusing on the mining industry until 1999.

In 1999, Dave took an active role in managing the lab, and in the spring of 1999 he repositioned the focus from mining to municipal water & wastewater. With its commitment to improving water quality CWM steadily grew. In 2002, to handle the growing environmental needs of municipal & industrial clients CWM moved into a new and larger building outside of Kittanning. In the first decade of the 2000s, CWM made a series of small acquisitions, including Aquatech, Duquesne Power, and Staley Water.

By 2010 CWM had grown into a regional footprint, and in October of that year, purchased D-Squared, an acquisition that allowed it expand its operational services. In 2014 CWM completed the acquisition of Precision Analytical (Now CWM Cleveland), increasing its presence in Ohio. In 2016 CWM continued to expand and moved into a new laboratory & headquarters in West Hills, Pa, later that year it acquired Clarion based Stewart Labs.

In the fall of 2017 CWM entered into a multi-year laboratory operational agreement with the Pittsburgh Water & Sewer Authority, growing its status as a leading water and wastewater company. Currently, CWM has close to 100 employees and works with over 200 municipalities, conducting testing on over 50,000 water samples annually.
