Schools with lead

Of 319 suburban schools that were tested for lead in drinking water, 69 had at least one sample at or above the federal threshold of 15 parts per billion. Absence from this list does not mean a school's water is lead free; 325 schools have done no testing.

The list below is interactive: Sort the list by clicking on the column headings, or look for your school district using the search box. You can also choose to view more districts at a time with the "Show entries" box.
