The filter first approach is more cost effective than a “test and tell” policy that has previously been proposed. The “test and tell” approach would require school districts to test all drinking water fixtures and then replace those that test positive for lead above a set action level. Our cost analysis shows that the filter first approach is both the most cost effective and health protective option.
The graph to the right shows that both the first year and the 10-year costs of the filter first approach are significantly lower than the test and tell costs. The 10-year cost savings may be as much as $331 million.
As long as the filters are properly maintained, the filter first method assures a reliable, lead-free source of water in schools.
