Problems We Found In Omaha, Nebraska's Drinking Water

Ernesto Esquivel | Water Nerd   

For Hydroviv’s assessment of Omaha, Nebraska'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 Omaha'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 Omaha's drinking water.

Where Does Omaha Source Its Drinking Water? 

Omaha draws its tap and drinking water from the Missouri River, Platte River, and the Dakota Sandstone aquifer.

Lead in Omaha’s Drinking Water

Based on the 2017 water quality report, lead levels in Omaha ranged from less than 0.5 to 14.9 parts per billion. 10% of taps had levels over 6.4 parts per billion, which is in compliance with the loose EPA standard of 15 parts per billion. However, if you were to ask toxicologists, pediatricians, or the CDC they would all tell you that there is no safe minimum level of lead. Lead is a neurotoxin that can have serious developmental effects on children.

Arsenic in Omaha’s Drinking Water

Arsenic is a heavy metal that typically leaches into groundwater as surrounding bedrock naturally weathers overtime. According to the most recent data, Arsenic concentrations ranged from 2 to 5.07 parts per billion in Omaha's tap and drinking water. EPA set a Maximum Contaminant Level of 10 parts per billion for Arsenic, but several health and regulatory agencies believe 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.

Disinfection By-Products in Omaha’s Drinking Water

When water treatment facilities sanitize the water with chemicals such as chlorine, different contaminants can be created. These types of contaminants are called Disinfectant by products or DBPs. They are split into two categories: Total Trihalomethanes (TTHMs) and Haloacetic Acids-5 (HAA5). Concentrations of TTHMs averaged 43 parts per billion but were detected as high as 86.3 parts per billion. HAA5 concentrations averaged 19.3 parts per billion but were detected as high as 40.4 parts per billion.  For a bit of perspective, EPA set a Maximum Contamination Level of 80 parts per billion for TTHMs and 60 parts per billion for HAA5.  

Chromium 6 In Omaha’s Drinking Water

Chromium 6 is an unregulated toxic metal that's associated with metal processing, tannery facilities, chromate production, stainless steel welding, and pigment production. Concentrations of Chromium 6 were found to be ranging from 0.13 parts per billion to 1.4 parts per billion. These levels are nearly 70 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.

Synthetic Organic Contaminants in Omaha's Drinking Water

Di(2-ethylhexyl)phthalate was also detected in Omaha's drinking water. This chemical is known for its ability to make plastic flexible. A toxicology report has shown that this chemical is known to cause reproductive problems in young males, stomach pains, and is labeled as a probable carcinogen. EPA set a Maximum Contaminant Level of 6 parts per billion for this contaminant. The Omaha water quality problem report detected concentrations of these chemicals ranging from less than 2 parts per billion to 3.11 parts per billion.
