The Comal Trinity Groundwater Conservation District (CTGCD) was created to help Comal County residents conserve, preserve, recharge, protect, and prevent waste of groundwater from the Trinity Aquifer which underlies all of Comal County.
The Comal Trinity GCD was created during the 2015 84th Texas Legislature with the enrollment of House Bill 2407 and became effective 17 June 2015. The bill provides the GCD the authority to issue bonds; and impose assessments, fees, or surcharges.
‘Well Educated’ Day Session is a free, one-day educational training for Texas residents who depend on household wells for their water needs. Well Educated is for private well owners who want to become familiar with groundwater resources, septic system maintenance, well maintenance, water conservation, water quality and water treatment.
Participants can bring their well water samples to be screened for common contaminants including fecal coliform bacteria, nitrates, arsenic and high salinity.
