Source of lead in San Marcos water still unknown
By Eleanor Beck, http://www.kvue.com
After spending more than $113,000 in taxpayer money to investigate the source of lead contamination in portions of San Marcos and Hays County water, neither government has found the origin of the problem.
Water to the Hays County Government Center was shut off to the public after tests revealed lead. The discovery prompted city-wide testing, which showed unacceptably high levels of lead at several other sites.
“We’ve tried everything,” said Clint Garza, county development services director. “Since last summer, we’ve tested every piece of pipe that we can pull from the building.”
That includes samples from all four manufacturers the county purchased pipe from to build the government center, which was completed in 2011. Garza said the samples were subjected to rigorous tests in highly corrosive environments, designed to break them down and make them release any lead contained in the pipe lining. The tests were repeatedly unsuccessful.
