Case Study: Arsenic Treatment System's Novel Design Increases Media Life Up To 40%
The Garber-Wellington aquifer, a 280-million-year-old geologic formation in central Oklahoma, supplies municipal, industrial, commercial, agricultural and domestic water for that part of the state. All the major communities in the region, except Oklahoma City, rely either solely or partly on groundwater from this water source.
When the USEPA lowered the maximum contaminant level for arsenic in drinking water to 10 µg/L in 2006, all noncompliant wells in the region were removed from service. The shutdown included 11 wells serving Norman, Okla. – one third of the city's total well capacity. This reduced the average well production in Norman from nearly 5 million gallons per day (mgd) to just over 2 mgd.
