LONG BRANCH: Long Branch School District Superintendent Michael Salvatore said the schools' water sources have been re-tested and are now lead-free.
Testing was conducted on March 4 and some sinks and water fountains had elevated lead levels.
"We tested more than 450 points when we came across 9 specific points, it was revealed that they were fountains that were turned off or sinks that were not used for more than 48 hours," Salvatore said in a message on Facebook. "But we tested them anyway and those nine points ended up failing and showed elevated lead levels."
These nine water sources in six of the district's schools were found to have more than 15 parts per billion of lead, which is the lead action level set by the US Environmental Protection Agency. Signs stating "Do Not Drink, Safe For Handwashing Only" were placed on the water sources following the testing results.
Salvatore said the district realized it hadn't flushed them properly, so they were tested again and the results came back "perfect."
"So now all 450 points have been reviewed and are clean and clear and are certainly safe," Salvatore said.
Lead enters drinking water primarily as the result of the corrosion or wearing away of materials containing lead in the water distribution system and in building plumbing such as the lead-based solder used to join copper pipe, brass and chrome-plated brass faucets.
Lead is most dangerous for pregnant women, infants and children under the age of six because it can cause damage to brain and kidneys and can interfere with the production of red blood cells.
