ConVal High School recently completed testing for lead in drinking water as part of an ongoing effort under NH House Bill 1421 requiring schools to test for lead and to act when lead is at or above 5 parts per billion (ppb).
Samples were collected from 157 potential drinking water outlets (e.g., classroom or bathroom faucets, kitchen sinks, and drinking fountains); 19 samples tested at or above the level where action must be taken.
Please see this letter from Facilities Director Tim Grossi for further details.
