75 Years of NEIWPCC

Advancing clean water in the Northeast since 1947.

NEIWPCC was formed to tackle water quality issues that couldn’t be solved by any one state on its own – whether it was developing water quality standards, creating the first wastewater operator training program in the region, or facilitating interstate collaboration around key topics.

NEIWPCC has been instrumental in engaging and convening water quality professionals from New England and New York to collaborate on water, wastewater, and environmental science challenges.

Our roots stretch back to the post-World War II era, when pollutants often flowed unchecked into lakes, rivers, and bays. To address the bleak state of our waterways through a united approach, Congress established interstate water pollution control commissions, such as NEIWPCC (originally known as the New England Interstate Water Pollution Control Commission) in 1947.

A watershed year

In 2022 we are celebrating two “watershed” moments in one year. In addition to NEIWPCC’s 75th anniversary, this year also marks the 50th anniversary of the passage of the federal Clean Water Act of 1972. This landmark environmental legislation has defined how we protect and restore our water resources to this day.
