The Suffolk County Impact

400

The Lab tests for 400 compounds, which is 251 more than required by our regulators.

32,000

SCWA's Laboratory instruments can test down to Parts Per Trillion. To get an idea, one ppt would be represented by a single drop of food coloring in 18 million gallons of water. Another way to view it as representing a single second out of 32,000 years.

6,000

SCWA has just under 6,000 miles of water main in the ground throughout our service territory. Laid out end to end, that's enough main to stretch from Suffolk to Siberia.

Our mission is to provide the customers of the Suffolk County Water Authority the highest quality water at the lowest possible cost with excellent customer service.
