Concerned About Water Chlorination Or Trihalomethanes (THMs) In Your Water?
What are Trihalomethanes?
They are a group of disinfection byproducts that form from a chemical reaction between water and the chlorine used to disinfect it. Chlorine is the commonly used disinfectant to treat municipal water in New York State. Triahalmethanes were discovered in 1974 during the water disinfection process and let the EPA to change the National Interim Primary Drinking Water Regulations and include a maximum contaminant level to 80 parts per billion, or 80 micrograms per liter.
The primary trihalomethanes of concern in drinking water are chloroform, bromodichloromethane, dibromochloromethane, and bromoform. In human and animal studies these have been linked to bladder and colon cancer at relatively low exposure; at high exposure there is a link between trihalomethanes and birth defects, other reproductive issues, and damage to the kidneys, liver, and nervous system.
Can I Remove Trihalomethanes in My Water?
You bet! The first thing you need to do is to test your water to determine the THM level, as well as other impurities. Test your water if you are on a regulated water source and you notice a high level of chlorine in your drinking water or if the system reports an issue with managing trihalomethanes. You are not likely to be as concerned if you have a groundwater source, unless this source has been disinfected or directly connected to a surface water body that is impacted by a landfill or waste discharge that contains trihalomethane.
Upon your water test results, along with the inspection of your plumbing and discussing your family’s wants and needs, a water treatment specialist will be able to provide the right application to appropriately treat your water!
