Atrazine in Home Drinking Water


If you are on a well or even if you are serviced by a municipal water supply which relies even partially on surface and ground water sources, then atrazine may be among the potential contaminants with which you must be concerned when looking at your home drinking water.

What is Atrazine?
Atrazine is a chemical which is commonly used as an herbicide. It is most often used to prevent the growth of grassy and broadleaf weeds and is frequently employed by farmers who are growing row crops, like wheat, corn, and soybeans, to name a few.

How does Atrazine Get into Home Water Supplies?
Run off from fields where atrazine is used as an herbicide is how this chemical gets into the surface water and ground water supplies. Both of these water sources feed personal wells and can be sources for municipal water supplies too. This makes atrazine a potential concern for any home water supply, though people who depend on wells and those who live in close proximity to farming communities may see a higher incidence of atrazine contamination.  Ground water contamination has a far reach though, which means that even if you don’t live near any farms at which atrazine may be used, it could still potentially make its way into your home water through the complex ground water systems on which we all depend.

What are the Dangers with Atrazine?
Prolonged consumption of atrazine contaminated water can lead to problems with the cardiovascular system and reproductive problems as well. Risks increase with highly elevated levels of atrazine contamination and with the length of exposure.

How to Determine if Atrazine is a Problem
The most conclusive method for determining if atrazine is present in your home water supply is to have a comprehensive water quality analysis performed. This will not only show the presence and level of atrazine in your water, but will also tell you any other quality concerns which should be addressed as well.

What Levels of Atrazine are Unsafe?
The Environmental Protection Agency (EPA) asserts that certain, limited levels of atrazine in drinking water are expected and safe. Specifically, the EPA’s regulations indicate that levels measuring 0.003 milligrams per liter or 3 parts per billion and lower pose no significant health risks. Some individual consumers prefer not to take the risk of having any atrazine present in their home drinking water however, and as a result, decide to implement water filtration systems in their homes to fully eliminate this chemical from the drinking water supply.

Which Water Filter is Best for Removing Atrazine?
The most effective water filters for removing atrazine from drinking water are those that utilize granular activated carbon. There are water filters which are specifically designed for addressing concerns with chemicals like atrazine and filters that address multiple concerns. Multi-stage filtration systems which include carbon filters can capture and remove a range of contaminants from water. A knowledgeable representative with a reputable water filtration company can help you determine which filters will work best for your specific needs, including which will eliminate the health risks associated with atrazine contamination.
