Since 1944, the Westchester County Environmental Laboratory has been a certified Public Health Laboratory and has contributed to protecting the health of citizens in Westchester County and the Lower Hudson Valley. In those 66 years, our scope has expanded from testing milk products for a handful of parameters, to testing water, soil, and air samples for a wide variety of EPA and New York State mandated tests. 

We provide testing services to a number of government agencies, health officials, engineers, hospitals and medical facilities, schools, businesses, lawyers, realtors, homeowners and citizens. 

Our state-of-the-art facility and a highly trained staff enable us to provide the best in bacteriological, inorganic, organic and radiological testing.  Our QA/QC department ensures that all reported results meet or exceed all standards for precision and accuracy.
