"This milestone represents the last stage before the AEC begins serving the Lake Stockholm community, and everyone is excited to work through to completion the provisioning phase" said Tonya Chandler. "We're proud to see our work recognized by Chemical Engineering, and we're equally proud to as we help deliver affordable, PFAS free water to the world. The State of New Jersey is a leader in PFAS clean-up efforts.
