At our January 14, 2019 evening meeting at the Commack Public library , CCA hosted speakers from the Suffolk County water Authority.   One of the speakers was a 2009 graduate of Commack High school: Seth Wallach ! 

 The water authority always offers an outstanding presentation on our drinking water.  This was their second visit to a CCA meeting !  Take a field trip on a Thursday afternoon tour of the water authority  educational showcase in Hauppauge. Call the water authority for details..
We learned that ::
  • Seventy percent of the SCWA wells do not require treatment. Of the wells that require treatment, 119 GAC tank carbon filter have been installed and are maintained by Calgon water technicians remove the charcoal filters to Pennsylvania for  cleaning and reuse.
  • The charcoal carbon filters are being replaced with coconut shells which remove even more pollutants.  
  • There are also 29 Iron/manganese removal systems to clear these elements which can clog pipes.
  • There is a new material being used for water pipes It is called Ductile iron concrete lined pipe. It should last much longer than current materials.
  • A test system to remove 1-4 dioxane is working well enough to be approved by the Dept of Health.
  • Lime is added to the water to maintain a neutral (7) ph factor .
  • Check out WATER TROQ on the SCWA website for details about your local water quality
  • Much of Long island is over an aquifer. 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.A heat pump is supposed to be installed with a well in the yard. If not you will draw water from Suffolk County Water authority. One estate in the Hamptons drew  25 million  gallons  in one year for their heat pump and  other uses.
  • The Upper glacial aquifer is too polluted in most areas to draw drinking  water.
  • In 1986 the state halted the drilling of new wells in to the Lloyd to preserve it for the future.
  • Storage of town highway winter salt and sand is now inside of a covered  drinking building in Islip Terrace, because the rain was washing it into the nearby SCWA well. Salinity increased causing  issues.
  • New water piping was installed along Indian Head rd. and on Leah court in Commack. Wider four inch  water piping was installed on Leah Court replacing  old two (2) inch pipes.
