In November 2014, our guests were Suffolk County Water authority representatives explaining Suffolk County water systems.
The Suffolk CountyWater Authority was established in 1951. It operates 614 wells and 237 pump stations in Suffolk County. SCWA has installed generators so that pumps are always functional during a power failure. Thus no one lost water flow during Hurricane Sandy.
In the winter only 200 of the 614 pumps are used to provide for the county's water demands. During the summer SCWA must turn on 414 additional wells to supply water for pools and lawns. Lime is added to the water to make it less acidic. Carbon is added to the water to remove iron . Giant ion filters are used to remove nitrates from the water.
There are 3 aquifers on Long island. Water from the Upper Glacial aquifer has filtered down over a 10 year period and is too polluted to use for drinking water. Commack's 5 wells draw water form the Maghothy Aquifer which holds cleaner filtered water that is about 100-500 years old. . The Lloyd Aquifer is the deepest aquifer and the water is thousands of years old thus supplying the purest filtered rainwater. Only communities with salt water intrusion into other aquifers, such as Long Beach, are eligible for water from these deepest wells. The Lloyd aquifer is being held in reserve for Long Islands future needs.
How much local expansion will one day create a water crisis?
