At our January 14, 2019 evening meeting at the Commack Public library , CCA hosted speakers from the Suffolk County water Authority. The water authority always offers an outstanding presentation regarding our drinking water. We learned that much of Long island is over an aquifer. The surface Upper glacial aquifer is too polluted in most areas to draw drinking water. . The deepest purest aquifer is the Lloyd aquifer. Only Long Beach and Atlantic Beach draw pure water from the Lloyd due to salt water intrusion into their wells in the Magothy aquifer. As more water is pumped from the Magothy water aquifer, which supplies our water, more salt water intrusion occurs.

Seventy percent of the SCWA wells do not require treatment. Of the wells
that require treatment, 119 GAC tank carbon filters have been installed and are maintained by
Calgon water technicians The charcoal carbon filters are
being replaced with coconut shells which remove even more pollutants. A test system to remove 1-4 dioxane is working well enough to be approved by the Dept of Health. There are also 29 Iron/manganese removal systems to clear these elements which can clog pipes.If the water tastes different from time to time it is because Lime is added to the water to maintain a neutral (7) ph factor There is a new material being used for water pipes It is called Ductile iron concrete lined pipe.
- A heat pump is supposed to be installed with a well in the customer yard. If not, you will draw water from Suffolk County Water authority as did one estate in the Hamptons ,which drew 25 million gallons in one year for their heat pump and other uses.
- Storage of town highway winter salt and sand
is now inside of a covered building in
Islip Terrace, because the rain was washing it into the nearby SCWA well. Salinity increased causing issues.
