Water well screenings set for March 23-24 in Callahan, Shackelford counties
Residents are invited to have private well water tested, attend results meeting in Baird
The Texas Well Owner Network, TWON, will host private water well screenings in Callahan and Shackelford counties on March 23 and follow with a results meeting on March 24.
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.”
Water sampling and meeting information
Water samples can be dropped off on March 23 from 8:30-11 a.m. at the following locations:
- AgriLife Extension office for Callahan County, 1257 Farm-to-Market Road 2047, Baird.
- AgriLife Extension office for Shackelford County, 225 S. Main St., Albany.
The results and interpretation meeting will be held from 9-10:30 a.m. on March 24 at the Temporary Operations Building, 1257 Farm-to-Market Road 2047, Baird.

Pigg said it is essential for those submitting samples to attend the follow-up meeting to receive results, learn corrective measures for identified problems and improve their understanding of private well management.
