Private wells – Test for a silent killer 
By Mike Ekberg, Manager for Water Resources Monitoring and Analysis

There may a silent killer lurking in private wells used for drinking water.

Recent groundwater studies in our region show that drinking water in up to 20 percent of private wells contains high levels of arsenic.

Long-term exposure to arsenic through drinking water is associated with multiple serious health problems. Arsenic is a known human carcinogen, linked to cancers of the bladder, lungs, skin, kidney, nasal passages, liver, and prostate gland.  

In addition, exposure to arsenic interferes with the immune system, impacts cardiovascular, pulmonary, neurological, and hormonal processes, and may be a contributor to the development of type 2 diabetes.

Elevated arsenic not uncommon in regional groundwater
Arsenic is an element and a minor component of the rock and soil present in local aquifers. Under the right conditions groundwater dissolves arsenic in the aquifer and carries it into wells. Public water systems must test for arsenic. If arsenic levels are high, they are required to remove it.

Unlike public water supplies, private wells usually are not routinely tested. 

Drinking water comes from a private well? Get your water tested. 
How can you tell if your well water has high arsenic levels in it? You can’t, not without a laboratory test. That’s why I urge well owners who use their wells for drinking water to get their water tested. A laboratory test will typically cost anywhere from $20 to $25. If you use a private well for drinking water, it’s important to test your water for arsenic. If you don’t, you run the risk of consuming drinking water with elevated levels of arsenic.

Removing arsenic
Removing arsenic from drinking water can be complex. In general, there are two major categories of removal systems, point of use (POU) and whole-house. POU arsenic removal systems remove arsenic at a single tap where the water is consumed. POU arsenic removal systems do not remove arsenic throughout the entire house. Whole-house arsenic removal systems remove arsenic at the point where water enters the house, distributing treated water throughout the entire house.

A recent study by the U.S. Geological Survey and MCD found the effectiveness of treatment systems in removing arsenic is largely dependent upon the arsenic level in the untreated water. The higher the arsenic level in the well, the less effective arsenic removal systems tended to be. Fortunately, studies of our regional aquifers show that most water has arsenic levels that can be removed with arsenic removal systems that are available on the market.

Currently, there are two labs in our area that will test your water. Call them for fees and more information: 
 
Montgomery County Environmental Laboratory

Other resources to help you understand how to test your well water
The Ohio Environmental Protection Agency has a website with contact information about state-certified labs that can help with testing. Heidelberg University also offers testing services.
 
The Ohio State University (OSU) also offers an on-line tool to help you understand the test results. The OSU site offers a lot of information for well owners.
