Lead

The WJWW’s initial sampling and monitoring program in 1992 demonstrated that samples for lead were above the action level established by the Lead and Copper Rule.  The WJWW subsequently created a program to optimize corrosion control for the piping within the distribution system and the piping within your home or business.  This program consists of raising the pH of the water to about 7.5 to make it less corrosive to pipe materials, and of adding a blend of poly-orthophosphate to the water.  The poly-orthophosphate blend used at the Larchmont and Rye Lake Stations inhibits corrosion by creating a coating on pipe walls and helping to prevent lead and copper from entering the water.  The WJWW activated this treatment process in 1999. 

Therefore, we must include the following statement in this report; “Infants and children who drink water containing lead in excess of the action level could experience delays in their physical or mental development.  Children could show slight deficits in attention span and learning disabilities.  Adults who drink this water over many years could develop kidney problems or high blood pressure.”
