Since The Environmental Working Group recently released a report about the prevalance of radium in US water supplies, our email and support line have been filled with questions about the toxic, radioactive heavy metal. The purpose of this article is to address a lot of these FAQs, and to discuss how to remove radium from drinking water. We'll be updating the article as more questions come into our Water Nerds!

What Is Radium & Where Does It Come From?

Radium is the product of the radioactive decay of uranium and thorium decay in rocks and soils. It's naturally occurring, and Radium levels tend to be higher in groundwater (wells, aquifers) than surface water (rivers).

Are The Recent News Articles The Result Of A Recent Spike In Radium Concentrations?

No. The reports examined radium concentrations that were logged in publicly-available databases the same databases that Hydroviv has been been using for years when we optimize water filters for our customers.

Should I Be Treating My Drinking Water Like Radioactive Waste?

Absolutely not. The concentrations of radium in drinking water are nowehere near the levels found in radioactive waste. There is absolutely no need to avoid being near your tap water.

What Can I Do To Remove Radium From My Drinking Water?

Unlike lead, which leaches into water from pipes, radium comes from the source water itself, so flushing your pipes does not reduce radium concentrations in water.Hydroviv Undersink filters are NSF/ANSI 53 certified to remove lead from drinking water. Boiling water also does not reduce or removing radium from drinking water.

  1. Ion exchange media. Cationic ion exchange media do a nice job selectively removing radium and uranium from drinking water, without removing minerals like calcium or magnesium. This is the approach we take in our water filters. 
  2. Reverse osmosis. Reverse osmosis is also a viable way to remove chromium 6 from water for people who are willing to accept the drawbacks, including low flow rate and complexity of installation. 

If you have any questions about filtering or removing radium from your drinking water, we encourage you to take advantage of Hydroviv’s “Help No Matter What” approach to technical support, where we will help you select an effective water filter system, even if it’s not one that we sell.

What You Need To Know About Groundwater

What Is Groundwater?

Groundwater is submerged water located among soils, cracks and pores, beneath the surface of the earth. Groundwater travels down gradient through geological formations and is stored in aquifers. Aquifers act as holding tanks for readily available drinking water. Rain patterns, hydrology, and ice/snow melt are the primary factors that affect how quickly a groundwater supply is replenished, also known as recharge. The recharge rate is how quickly aquifers are able to replenish the groundwater level after an influx of water.

Why Is Groundwater So Important?

It’s simple: It supplies drinking water to millions of Americans whose municipalities draw from groundwater sources (e.g. NYC, Tucson, Lincoln), as well as the 15% of people living in the U.S that use private wells as their drinking water source. Groundwater is also a major supplier of surface water in oceans, lakes, streams, ponds and wetlands. Crucial habitats and ecosystems are dependent on an influx of healthy groundwater, as well as surface water for public drinking water usage.

How Can Groundwater Become Polluted?

There are really two ways that groundwater can accumulate toxic chemicals:

  1. Natural-occurring chemicals: In some regions of the country, things like arsenic, radium, and uranium are naturally found in the rocks that come in contact with groundwater. 
  2. Man-made Pollution: Groundwater can also become contaminated by human activities including: agriculture, industry, landfills, localized pollution, and anything that involves discharging effluent into a surrounding waterway. Polluted water seeps through soil until it reaches the water table, where it can travel freely depending on the hydrology and permeability of an aquifer. Polluted groundwater then slowly travels through aquifers until reaching nearby surface water or being pumped through a well and consumed as drinking water.

Are There Federal Regulations That Protect Groundwater?

The Ground Water Rule was created in 2006 by the U.S Environmental Protection Agency to improve and inspect drinking water sources that may be potentially polluted by fecal contamination. This rule does not address human-made toxic and carcinogenic groundwater contamination. Additionally, the Ground Water Rule is specific to public water systems and excludes private wells.

The Federal Government does not oversee or have anything to do with regulating private wells. In fact, private wells aren’t even regulated by the Safe Drinking Water Act. This means that it’s at the discretion of the homeowner to determine if their private well water is safe for consumption. Testing private well water is extremely expensive and at times ineffective if the contamination type and concentration is continuously changing. Additionally, The Federal Government doesn’t regulate many of the contaminants in questions today.

How Can I Learn More About My Water?

If you have any questions about groundwater and regional water table information, we encourage you to take advantage of Hydroviv’s “Help No Matter What” approach to technical support, where we will help you, even if you have no desire to purchase one of our water filters. Truth be told, we have access to a much larger pool of water quality data than easily accessible to the general public. You can reach our water nerds by emailing hello@hydroviv.com or opening a Live Chat window in the bottom-left corner of this screen (we don’t use chat bots).
