Carpenter School Lead Test Results

July 17th, 2024 

Dear Parents and Guardians,  

We are writing to let you know that Carpenter School recently completed testing for lead in drinking  water. This is part of an ongoing effort related to New Hampshire’s House Bill 1421, which requires school and child care facilities to test for lead in drinking water and to act when lead is found at levels at  or above 5 parts per billion (ppb).  

Lead is a toxic heavy metal that has a range of adverse health effects if inhaled or swallowed. Lead  typically enters drinking water due to the wearing away of piping, faucets, fixtures and other plumbing  materials. Lead rarely occurs naturally in New Hampshire’s drinking water sources (groundwater or  surface water).  

Because lead is tasteless, odorless and colorless in drinking water, testing is a way to learn whether lead  is present. It is important to sample each faucet or water fountain that is used for drinking or food prep  because test results can vary between locations.  

During recent testing, we collected samples from 6 drinking water outlets (e.g., drinking fountains,  classroom faucets, kitchen sinks), with 4 samples testing at or above 5 ppb, the level where action must  be taken.  

We have removed access to these outlets until the problem can be corrected. The table below shows a  list of all of the tested outlets, their locations, sample results and our planned remediation.  

All sample results and additional resources from the New Hampshire Department of Environmental  Services (NHDES) can be viewed at gettheleadoutnh.org.
