United States Environmental Protection Agency (U.S. EPA) policies require all U.S. EPA supported monitoring projects to develop and implement a Quality Assurance Project Plan (QAPP) to describe measures taken within the project tasks to ensure validity and defensibility of all environmental data generated for their use. This document is intended to fulfill that purpose.
The overall objective for this QAPP is to determine the lead concentration at water outlets used for drinking and food preparation within schools and child care facilities so potential corrective action(s) may be identified for those outlets sampled and found to exceed the U.S. EPA drinking water lead action level of 15 micrograms per liter (μg/L). To accomplish the objective, pre-schools, elementary schools and child care facilities voluntarily participating in this project are prioritized by most at risk to lead in drinking water.
The lead sampling will consist of the collection of a first draw sample at those outlets according to this QAPP. If the initial sample from an outlet is found to contain lead at a concentration greater than 15 μg/L, local health department staff will work with the school or day care facility to identify corrective actions to minimize exposure to lead in drinking water. Activities conducted by this project are in accordance with the U.S. EPA's 3Ts for Reducing Lead in Drinking Water in Schools and Child Care Facilities, which is included as Attachment A to this document.
