Lead Testing in Schools and Child Care Facilities Drinking Water (LWSC) Program

Lead was a common component of faucets and plumbing until 1986 when it was banned due to its detrimental effects on public health and child development. While most new pluming is considered lead-free, it is still possible for homes, businesses, and schools to have lead-containing plumbing components. Fortunately, there are ever evolving programs being implemented at the state and federal level to reduce and remove lead contamination in public drinking water.

DEQ’s Lead Testing in Schools and Child Care Facilities Drinking Water (LWSC) Program is leading the way in an effort to eliminate lead from public drinking water, especially for one of the most at risk populations, our children. Public schools and public or private childcare facilities who participate in the program receive free sampling and laboratory testing to identify problem areas, and guidance on steps to eliminate lead from their facility’s drinking water. Read more below to learn about the program and the efforts being taken to keep our children safe.
