About the entity

Middlesex Water Company
Incorporated as a water utility in 1897, Middlesex Water Company provides a full range of regulated and non-regulated water, wastewater utility and related services in parts of New Jersey, Delaware and Pennsylvania.

Middlesex Water Company has completed Phase 1 construction of an advanced treatment facility at its Park Avenue wellfield that is effectively treating ground water to ensure compliance with all state and federal drinking water standards. Working in coordination with the New Jersey Department of Environmental Protection (NJDEP), Middlesex Water has begun a phased, start-up of its Park Avenue wellfield and is successfully introducing treated water into the distribution system. Water being delivered to customers is in compliance with all U.S. Environmental Protection Agency (USEPA) and NJDEP drinking water standards, including the newly established water quality standard for Perfluorooctanoic Acid, otherwise known as PFOA. The wells had been turned off since November 2021 when the Company had begun providing water from its surface water treatment plant and other sources. This plan to turn on, and treat, certain wells to support normal heightened seasonal demand was met with full approval from state regulatory agencies.

“As the summer months approach, our team has been focused on meeting consumption demands and constantly evaluating operational alternatives to continue to ensure a safe and reliable source of drinking water. Establishing an advance treatment solution while the larger portion of the new plant is being constructed allows us to utilize an existing source of supply and produce water from our wellfield that complies with state and federal guidelines while also supporting seasonal demands,” said Dennis Doll, Chairman, President and CEO. “We are grateful to our engineering and contractor partners for their roles in helping to identify and implement this effective solution,” added Doll.

As groundwater is slowly introduced back into the distribution system, customers may notice changes in the hardness of the water. As initial changes in the flow and direction of water stabilize, customers may also observe temporary, harmless discoloration. Customers who may experience temporary discoloration may choose to let their faucet run for 2-3 minutes until the discoloration subsides prior to consuming or using the water for cooking. The Company continues to monitor the water treatment process and perform water quality tests to ensure the continued safety of its water for consumption, bathing and other domestic needs.
