Public Water System: Nasa Johnson Space Center

MyTapWater.org's tap water quality report is the compilation of data collected from federal, state, and local government agencies, most prominently the EPA. We strive to populate the report with the latest data concerning water contaminants, lead and copper levels, and water quality violations. We only collect drinking water data from public water systems.

Summary Results


A summary view of the the times a water contaminant was tested and found to exceed the level set by the EPA (the MCL).

Maximum Contaminant Levels Exceeded (by year):

2013   (0) 2014   (1) 2015   (0)
chlorate

Contaminant Detailed Results


This a view of violations of maximum contaminant levels. In the expanded view you can see each know test date for a given contaminant, the result of the test, the minimum level that can be recognized in a test (MRL), and upper limit that is considered healthy (HRL).

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. Lead and copper can be — and often are — added to drinking water in between the water facility and a tap.

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.
