The Derry School District can expect to pay for more frequent water testing for its East Derry Memorial School, at least for the foreseeable future.
Superintendent Dr. Laura Nelson gave an update on the water situation in the June 21 School Board meeting.
The district accelerated its water testing after higher than standard concentrations of lead were detected during routine lead and copper water screening this past November. Lead levels were found to be elevated above 15 parts per billion, the level where action must be taken to reduce lead in drinking water. The concentrations were found in several faucets, while these were replaced, some continued to test higher than normal. A phosphate water treatment system was installed during February vacation. In addition, faucets in Rooms 101, 103, 105, 108 and 110 and the cafeteria hand sink were replaced. Faucets in rooms 101 and 108 continued to test above 15 ppb.
After “compliance testing” in January, a new baseline was established, Nelson said. Before, the district’s testing schedule was every three years. “Because we did show higher rates, our testing schedule is now every six months,” she said. “We have to be back on an appropriate level before we graduate to once-a-year testing.”
The next round of testing is in July, Nelson said.
At that time, the Buildings and Grounds Committee will review the results and decide how to move forward, she said.
“This will impact our budget,” Nelson said. “We will have to have a new contract for water testing.”
