When reading material about the uses of asbestos and mesothelioma-linked materials, you will mostly encounter facts about asbestos in the environment that can become airborne and lead to mesothelioma. However, largely because of the decay of cement water mains and the erosion of natural deposits, asbestos can also contaminate drinking water. Water suppliers are required by law to conduct routine monitoring to make sure that water levels are below the maximum contaminant level (MCL). According to the EPA, the MCL for asbestos in drinking water is 7 MFL. While MFL is not defined in the Basic Information about Asbestos in Drinking Water on the EPA website, the National Primary Drinking Water Regulations, as printed in the EPA publication, “Water On Tap: What You Need to Know,” define MFL as millions of fibers per liter. This document, updated in 2003, identifies the risk of developing benign intestinal polyps.
In Asbestos in Drinking-water, the Background document for development of WHO Guidelines for Drinking-water Quality the World Health Organization reports that most of the US population consumes drinking water with a concentration lower than 1 MFL. Research studying the effects of ingesting asbestos have yet to show a significant risk of cancer from ingesting asbestos. At the same time, the scientific community is concerned about possible risks and continues to research the area.
The EPA recommends finding out about your local source for drinking water. Numbers to call will appear on your water bill or telephone book’s government listings. If you contact your water utility company, they can provide you with a copy of the required annual consumer confidence report or water quality report that will give you information about the quality of water in your area. If your water supply is private, the EPA recommends that you contact the nearest community water system. For more information about asbestos and mesothelioma, please complete our online form.
