PFAS Testing Leadership

The Pre-Eminent Laboratory for Advanced PFAS Analyses and Detection

In October 2018, York opened the first and only PFAS laboratory in New York City to perform analysis on soil, groundwater and drinking water. The new Emerging Contaminants laboratory was built in York Analytical’s existing Queens NYC facility, which was certified by the NYS DOH and approved in January 2019.

In 2020, in response to new approaches by environmental professionals to identify PFAS in groundwater, York became the first analytical laboratory in the Greater New York region to conduct PFAS Analysis by TOP Assay.

York has continually invested in capital resources, top talent and technical know-how so clients get advanced PFAS testing and analyses faster and more efficiently than other labs deliver.

Clients have access to our senior technical team for in-depth expertise on any issues that arise, plus local facilities and the best courier service in the industry. Make York Analytical Laboratories your lab of choice for PFAS analyses and all your air, soil and water testing.
