Water well screenings set for Plum Creek watershed Aug. 4-5
Residents in Caldwell and Hays counties are invited to participate in screenings and results meeting
The Texas Well Owner Network, TWON, is hosting private water well screenings for residents in Caldwell and Hays counties on Aug. 4 and a results and education program on Aug. 5.

The cost of the screenings is $15 per sample. Water samples will be screened for contaminants, including total coliform bacteria, E. coli, nitrate-nitrogen, arsenic 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,” he said. “It allows them to learn more about how to improve and protect their community water resources.”
Well owners are encouraged to bring water samples from all wells on their property, as well as before-and-after samples from water treatment systems attached to the wells.

Water samples can be dropped off at the following locations on Aug. 4 from 8:30-11 a.m.:
