Oklahoma City (OK) Water Quality

Oklahoma City is a large public water system in EPA region 6 that provides tap water for the 73003, 73009, 73013, 73014, 73034, 73049, 73062, 73065, 73069 - 73071, 73079, 73084, 73093, 73099, 73102 - 73112, 73115 - 73122, 73127 - 73132, 73135 - 73137, 73141 - 73145, 73149 - 73151, 73157, 73160, 73164, 73165, 73169, 73170, 73173, 73189 zip codes. It has 7 facilities where the water supply was tested for 85 chemical contaminants that impact tap water quality and human health.

The maximum reported level of HAA5 (five regulated haloacetic acids) was 64.615 µg/L. Some (1 of 80 or 1%) of the latest water samples showed levels of HAA5 (five regulated haloacetic acids) that were at or above unsafe concentration levels. The maximum reported level of Manganese was 4.32 µg/L. There were 2 contamintants found in the Oklahoma City water supply at levels that were above the minimum reporting level. 1 of the contaminants were above the reference level, which means they may pose a risk to human health.
