Addition of Experienced Teams at Precision Testing Laboratories and Precision Analytical Services Significantly Strengthens York’s NJ Presence

On January 23, York Analytical completed the largest acquisition in the company’s history with the addition of two well-respected “sister” laboratories in Toms River, New Jersey.

  • Precision Testing Labs is expert at ground water and soil analyses with robust licensing by the New Jersey Department of Environmental Protection (NJDEP).
  • Precision Analytical Services is the largest New Jersey laboratory specializing exclusively in drinking water analyses and sampling services.

Both laboratories will continue to operate from the existing central New Jersey facility, where York Analytical has already begun construction of additional space for new PFAS and soil characterization laboratories.

“Mark Feitelson and Vini Bandeira have built first-rate laboratories steeped in client-service that culturally and strategically align with our focus. I am thrilled they will both be active members of York’s senior team,” said Michael J. Beckerich, CEO and president of York Analytical.

“This significant investment advances several important areas for York, and immediately provides a meaningful physical presence in New Jersey,” said Michael J. Beckerich, CEO and president of York Analytical.  “We are building around a great team in Toms River for the long-term and quickly expanding services to meet growing client needs.”

According to Mark Feitelson, founder and Laboratory Director of Precision Analytical Services, and co-founder of Precision Testing Laboratories: “The energy and focus of York’s senior leadership is a perfect match for our teams. We are very excited to incorporate our operation with York Analytical and take advantage of the resources they bring to grow our business to the next level.”

In addition to becoming York’s first full-service New Jersey laboratory, the acquisition advances three important areas for York that have quickly evolved in the last two years:

  1. York has now doubled the size of its drinking water operations, starting with the acquisition of Aqua Environmental (Newtown, CT) last January.  The addition of Precision Analytical Services accelerates this growth with its robust client-base, adds meaningful capacity to service new clients, and connects service areas in the tri-state region with York’s Connecticut and Hudson Valley (NY) operations.
  2. Strategically located within 90 miles of York’s NYC-based flagship PFAS laboratory, Precision Testing Labs, led by co-founder and Laboratory Director Vini Bandeira, has the expertise and physical space needed to expand York’s PFAS leadership in the heart of New Jersey.
  3. York will have the opportunity to recruit a new talent pool of chemists in central New Jersey to augment the strong team already in place at the Toms River location. The facility has comprehensive licensing already in place and room to build out new laboratory space to accommodate new hires looking to further their career in the environmental analytical field.
