Who We Are

A brief history of EDM Water Treatment

Ernie D. Mansfield founded the company in 1995. Based in Rancho Cucamonga, California, EDM Water Treatment concentrated its efforts in helping the coil coating and metal plating industries with their wastewater treatment issues. Recognizing that the larger water treatment companies could not give the badly needed attention to local environmental regulations and issues, EDM Water Treatment maintained a local customer base.

Through word of mouth and corporate influences, EDM Water Treatment began consulting with companies outside the local radius and in other states. EDM Water Treatment, Inc. is the consultant you can rely on in matters concerning waste, process and general compliance issues. EDM always contacts the local regulatory agencies to stay on top of regional differences in environmental laws. Although some customers are more than 1000 miles away, a local company atmosphere is still created.
