What My Water Data Means
Water data isn't always easy to interpret, but by following the links on this page you should be able to have most of your questions answered. By clicking the name of a water contaminant or secondary substance you can learn about that specific substance. Ultimately this page should give you some insight towards learning if your water is safe , what water filter you should buy (if any), and how well your local water compares against other sources.
Sources
The origin of MyTapWater.org's water data is explained on our Data Sources page.
Why Is My Water Data Not More Recent?
The recency of the data for your ZIP code depends on the last your water source was tested, by a federal, state, or local agency. 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.
