Hurricane Harvey Flooding Information: If you own a private water well and the well was under floodwaters, we recommend you have the well tested or disinfected. Information about GCHD drinking waster sample testing is available below. Click here for more information on testing/disinfecting from the Environmental Protection Agency.

The Drinking Water Sample Drop-Off Center at the Galveston County Health District (Health District) provides a safe and secure drop-off option for those requesting analytical testing of drinking water samples. Samples are transported from the drop-off center and analyzed by an outside NELAP certified laboratory not associated with the Health District.

The Water Sample Drop-Off Center accepts samples of water intended for human consumption and use. Water is tested for the presence of Total Coliform and E.coli. The analysis takes 24 hours to complete. Samples must be submitted in sterile bottles available at the Water Sample Drop-Off Center.
