A Brief History of Garden State Labs...

Garden State Labs was founded in 1943 by Mathew Klein, M.S. in Newark, NJ. In the late 40's the lab moved to Irvington, NJ and in 1988 it moved to its current facility in Hillside, NJ. Dairy, food and water bacteriology were the initial areas of analysis. Over the years chemical analyses including minerals, heavy metals, pesticides, herbicides, toxic organics and volatile organic compounds were instituted.

In the 60's, and 70's environmental analysis become an important facet of laboratory testing and Garden State Labs led the field in bringing these techniques to New Jersey. During this period Garden State Labs became very involved with swimming pool and other recreational bathing water testing. In the mid 70's Harvey Klein, M.S. joined his father in the lab and is currently laboratory director.

In the 80's and 90's our analytical instrumentation section grew with the acquisition of graphite furnace atomic absorption spectrophotometry (GF-AA), gas chromatography mass spectrometry (GC-MS)and inductively coupled argon plasma atomic emission spectrophotometry (ICAP). This allowed for extensive analysis of drinking water, wastewater, sludges, soils, solid and hazardous wastes.

Our microbiology section kept up to date with advancements in the field, especially with rapid detection methods for pathogens, including salmonella and E. coli O157:H7, and food safety including Hazard Analysis and Critical Control Point System (HACCP) information.
