Frequently Asked Questions

Common questions about SB1662

Q

What does Texas SB1662 do?

SB1662 fundamentally alters the inspection dynamic for public drinking water systems utilizing groundwater by statutorily capping the notification period for complaint-based water quality testing at 24 hours. This eliminates the "preparation window" previously used by operators to flush lines or adjust treatment prior to TCEQ arrival, effectively mandating a state of perpetual audit-readiness for all groundwater utilities.
