Abandoned wells, not plugged, within ___ mile of a proposed well site must be reported to TCEQ.

The requirement to report abandoned wells that are not plugged within a specified distance of a proposed well site is crucial for ensuring environmental safety and protecting groundwater resources. The correct distance is indeed 1/4 mile, as this distance is established to mitigate risks associated with groundwater contamination and to ensure proper management of water resources.

Abandoned wells, if not properly sealed, can serve as conduits for contaminants to enter the aquifer systems, thereby compromising water quality. By reporting these wells within this specified distance, the TCEQ can assess potential risks and enforce necessary measures to protect both public health and the environment.

The other distances provided, such as 1/2 mile, 1 mile, and 1/8 mile, do not align with specific regulatory requirements outlined by TCEQ for abandoned well reporting. Each of those options may reflect different considerations or contexts in water management but do not fit the established regulation concerning this particular requirement. Thus, understanding the 1/4 mile threshold is essential for compliance with TCEQ regulations and for the safeguarding of water resources.
