Water well screenings in Brewster, Jeff Davis, Presidio counties set for July 20-21
Residents can receive low-cost well water screenings, results and rainwater harvesting education
The Texas Well Owner Network, TWON, is hosting private water well screenings and a rainwater harvesting presentation for residents in Brewster, Jeff Davis and Presidio counties July 20-21.

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.”
