Further comments

Looks like AZ has a capacity to produce almost 1 million acre feet of treated water. Only 56% is Class A+, which means the rest is lower quality. According to a pie chart, 35% of treated wastewater is disposed into watercourses, 2% disposal to percolation ponds, and 9% goes into recharge facilities, 7% to tribes, and the rest is either reused or sent to Mexico.
Class A+ standards are based on the 1972 Clean Water Act, and do not account for CECs.
ADEQ has not updated their water standards since 2001.
