Private water well screenings set for March 4-5 in Hays County
Residents are invited to get well water tested, attend results meeting in Wimberley
The Texas Well Owner Network, TWON, will host private water well screening in Hays County on March 4-5.

The cost of the screening is $15 per sample, and residents may submit as many samples as they would like. Water samples will be screened for contaminants, including total coliform bacteria, E. coli, nitrate-nitrogen and salinity.
The TWON program serves residents who depend on household wells for their water needs, said Joel Pigg, Texas A&M AgriLife Extension Service program specialist and TWON coordinator, Texas A&M Department of Soil and Crop Sciences, Bryan-College Station.
“The TWON program was established to help well owners become familiar with Texas groundwater resources, septic system maintenance, well maintenance and construction, and water quality and treatment,” Pigg said. “It allows them to learn more about how to improve and protect their community water resources.”
