Who We Are

Garden State Laboratories, Inc. is a certified independent water, food and environmental testing laboratory. We analyze drinking water, wastewater, sludges, biosolids, soils, solid wastes, hazardous wastes, monitoring wells, food and dairy products for chemical, bacteriological and other microbiological contaminants. In addition we test recreational bathing waters such as swimming pools, whirlpools, hot tubs, lakes, and beaches for bacteria and chemicals. We also help develop and implement HACCP plans for the food industry.

With more than seven decades of involvement in these fields, Garden State Labs would like to share our experience, expertise and valuable insight in these branches of environmental science, food science and public health. This site will continue to expand as a resource for those interested in finding up-to-date and hard-to-find information relating to methodologies, regulations and testing capabilities in these fields.

Along with our laboratory facility in Hillside, New Jersey, we have a Jersey Shore Office in Barnegat, Ocean County, a West Jersey Office in Glen Gardner, Hunterdon County and a North Jersey Office in Sparta, Sussex County. Our offices are video-linked back to our main lab for your convenience. We also have sample drop off locations throughout New Jersey. We maintain a fleet of field samplers to provide you with unparalleled sample pick up service.

We value your feedback and input. If you have suggestions, please feel free to drop us a line and let us know how we can improve this site or help you with your testing needs.

Garden State Labs earned NELAC Accreditation in January 2001. This is the highest level of laboratory accreditation in the United States. Garden State Labs is Certified in the States of New Jersey, New York and Pennsylvania. Please see our Certifications page for detailed information.
