You might have recently heard stories in the media about Chromium levels in Phoenix water. The AZ Water Association membership is responsible for treating and distributing drinking water, and takes seriously the requirements to ensure that public health and safety expectation of our customers is met. In collaboration with the American Water Works Association and the Water Environment Federation (WEF), we work to promote appropriate regulatory standards, and work with decision-makers on how to best treat for contaminants.
The current drinking water standard or Maximum Contaminant Level (MCL) for Total Chromium is 100 parts per billion (ppb). Almost all of the water utilities in Arizona monitor Chromium-6 under the current Unregulated Contaminant Rule (UCMR); the most recent results ranged between 1.2 ppb and 11 ppb, after a quick check of water quality reports from the Phoenix Metropolitan Area, meaning that according to national standards, we are still well below dangerous levels.
