Where does your water quality data come from?
Our data comes from the EPA's Safe Drinking Water Information System (SDWIS) and other official government sources. We update our database regularly to ensure accuracy.
How often is the data updated?
We sync with EPA databases monthly and update city reports as new data becomes available. Water utilities are required to report to the EPA quarterly.
Can I use your data for research or publications?
Yes! Our data is compiled from public EPA sources. Please contact us at data@uswatergrade.com for details on attribution and proper usage.
My city isn't listed. Why?
We're continuously adding cities. Some smaller municipalities or those with limited EPA reporting may not be included yet. Contact us and we'll prioritize adding your city.
