Lead and Copper Data


Lead and copper are recorded separately from other contaminants because of the Lead and Copper Rule. As with all other results, these are the findings at the water supply level. Lead and copper can be — and often are — deposited in drinking water in between the water facility and your tap.

Why Is My Water Data Not More Recent?

More information about the timing can be determined by learning about the dataset in question and seeing how often the EPA (other another governing body) mandated testing.
