water quality; testing; on-site
SB 1445 modifies Arizona's water quality regulations to allow small municipalities (with populations between 1,000 and 10,000) to use EPA-approved on-site equipment for bacteriological testing of wastewater. It updates permit requirements for facilities discharging pollutants, including specifying that small towns may conduct this testing on-site instead of sending samples to external labs. The bill directly affects local governments and wastewater facilities in smaller communities by streamlining testing procedures while maintaining EPA standards. It also clarifies permit processes for aquifer protection and aligns with federal Clean Water Act requirements.
