First, make sure to check the searchable database of the state’s radiation test results for every water system in Texas.
You can find that searchable database by clicking here.
Information in this database is limited only to types of radiation that the EPA regulates and mandates testing for.
Next, if you want to check for radon, an unregulated form of radiation your water company does not have to test for, various consumer home test kits can be purchased online and should not cost more than about $40, including lab work. Make sure the lab you use is certified by the EPA.
Then, if you decide you want to remove the radiation from your water, consider installing a reverse osmosis water filter in your home. Most normal filters will not get radiation out of drinking water.

For an in-depth look at what it takes to install a reverse osmosis kit yourself, click here and here for part two.
If you choose to hire a professional to do the installation, make sure you check them out first with Better Business Bureau before agreeing to hire them.
