For the past year the KHOU 11 News I-Team has been investigating the quality of the tap water in Texas. What they found was surprising: That many of the state's communities have a real problem with radioactive contamination in their local drinking water. However, the team also discovered that many of those consuming it didn't know they were also being exposed to a health risk. State scientists found some of Texas' water could pose a 1 in 400 cancer risk. Neighborhoods across the state have been getting illegal amounts of a particularly damaging form of radiation, an exposure that some say was covered-up" by Texas officials. Water with under-the-legal-limit amounts of radiation still might not be "safe". Concentrated "bursts" of radiation could be released into your home ... from water pipes that become "a hidden risk" themselves.
