Problems We Found In Tucson's Drinking Water

Analies Dyjak | Policy Nerd   

For Hydroviv’s assessment of Tucson, Arizona’s drinking water, we collected water quality test data from the city’s Consumer Confidence Report and the U.S. Environmental Protection Agency. We cross referenced Tucson's water quality data with toxicity studies in scientific and medical literature. The water filters that we sell at Hydroviv are optimized to filter out contaminants that are found in Tucson’s drinking water.

Where Does Tucson Source Its Drinking Water?

Tucson sources its drinking water from 200 groundwater wells and the Colorado River.

Chromium 6 In Tucson's Drinking Water

Chromium 6 is a highly toxic metal that is currently unregulated by the EPA. In recent years, Tucson has had a major problem with this dangerous contaminant. Chromium 6 pollution is associated with metal processing, tannery facilities, chromate production, stainless steel welding, and pigment production. The city of Tucson detected levels of Chromium 6 as high as 94 parts per billion and averaged 4.72 parts per billion. These levels are nearly 4700 times higher than the concentration determined to have a negligible impact on cancer risk. EPA has acknowledged that Chromium 6 is a known human carcinogen through inhalation, but is still determining its cancer potential through ingestion of drinking water. Lung, nasal and sinus cancers are associated with Chromium 6 exposure. Ingestion of extremely high doses of chromium 6 compounds can cause acute respiratory disease, cardiovascular, gastrointestinal, hematological, hepatic, renal, and neurological distress which may result in death.

Perfluorinated Compounds In Tucson’s Drinking Water

This years water quality report for Tucson, Arizona included test data from two Perfluorinated Compounds: Perfluorooctane-sulfonic acid (PFOS) and Perfluoro-1-hexanesulfonic Acid (PFHxS). Concentrations of PFOS were detected as high as 56 parts per trillion, and averaged 28 parts per trillion. Concentrations of PFHxS were detected as high as 420 parts per trillion and averaged 210 parts per trillion. The Agency for Toxic Substances and Disease Registry (ATSDR) recently recommended setting a Minimum Risk Level of 20 parts per trillion for PFOS, but is still researching the toxicity profile of PFHxS. These data from the ATSDR are preliminary and the effects to human health are still unknown. This category of chemicals are “emerging contaminants” which means they are thought to pose a potential threat to human health and the environment, but haven't yet been regulated. Perfluorinated Substances contribute to environmental contamination largely due to the fact that they are highly resistant to the degradation processes, and thus persist for many years in water, air and can enter the food chain via bioaccumulation in certain animal species.

Arsenic In Tucson’s Drinking Water

Arsenic is a heavy metal that typically leaches into groundwater as surrounding bedrock naturally weathers overtime. The concentrations of Arsenic in Tucson’s water were detected as high as 7 parts per billion. The federal Maximum Contaminant Level for Arsenic in drinking water is 10 parts per billion, but regulatory agencies acknowledge that this level should be reduced to 1 or even 0 parts per billion. Arsenic is a toxic substance that is linked to a long list of health problems in humans. For example, arsenic can cause a number of different cancers (e.g. skin, bladder, lung, liver, prostate), as well as create non-cancerous problems with cardiovascular (heart/blood vessels), pulmonary (lungs), immune, neurological (brain), and endocrine (e.g. diabetes) systems. Hydroviv recommends purchasing a filter that is optimized to remove Arsenic from your drinking water, especially if you’re serviced by a private well.

It’s important to note that only a handful of contaminants are required to be included in annual Consumer Confidence Reports, and that there are hundreds of potentially harmful unregulated contaminants that aren’t accounted for.
