How Well Do Hydroviv Water Filters Remove Arsenic and Uranium?

Maine Well Water Case Study: 

A prospective customer reached out to us about a year ago with concerns about his well water. After sending the well water test results from an EPA accredited lab to our science team, we were able to determine that his well water water was well above EPA regulatory standards for both arsenic and uranium. This meant that the levels in his well water were above what EPA considers to be safe for human consumption. Private well owners are on their own for determining the safety of their well water.

How Well Did Hydroviv Remove Arsenic and Uranium?

Hydroviv’s Undersink Water Filter brought his arsenic levels down from 23.9 parts per billion to undetectable. For a bit of perspective, his pre-filtered levels were over twice as high as the EPA federal standard for arsenic. Hydroviv filters also brought his uranium levels down from 235 parts per billion to undetectable. His pre-filtered levels were over 7 times higher than the EPA federal standard for uranium. The graph below shows the uranium and arsenic levels, before and after installing a Hydroviv Undersink Water Filter.

Arsenic in Drinking Water:

Arsenic is a naturally occurring heavy metal found in bedrock throughout the United States. Arsenic leaches from bedrock into well water overtime through a process known as natural weathering. The presence of arsenic is entirely dependent on your area’s geology. This means that arsenic may be present in seemingly pristine well water located far away from factories and other sources of pollution. Arsenic can cause various types of cancers, including bladder, lung, liver, and prostate. Some states with the highest rates of bladder cancer also have the highest levels of arsenic in groundwater.

Uranium in Drinking Water:

Uranium is a naturally occurring radionuclide typically found in groundwater. Similar to arsenic, the presence of uranium in well water is dependent on your area’s geology. Long term exposure to uranium in drinking water increases the risk of kidney cancer in humans. The current EPA federal standard for uranium in drinking water is 30 parts per billion. Most standard pitcher and refrigerator pitchers do not include the necessary filtration media to remove uranium from drinking water.

How Do I Know if Arsenic and Uranium are in My Well Water?

Our team of Water Nerds analyzes every order based on the zip code provided at check out. If you live on a private well, we use publicly available USGS data, State Source Water Assessment Program (SWAP) data, municipal Consumer Confidence Reports (CCR), and other internal well water test results. Using these data, we are able to determine the contaminants that are likely present in your well water.
