The Missouri Department of Natural Resources invites Missourians to celebrate Drinking Water Week by taking a moment to reflect on the importance of a clean abundant supply of quality tap water.
DNR says whether you need it to cool off after a workout or warm up in a hot bath, your tap water is there when you need it.
Drinking Water Week, May 3-9, recognizes the essential role drinking water plays in our daily lives, with the theme “There when you need it.”
Water, one of our most precious natural resources, is too often taken for granted, as most of us turn on our faucets and expect a plentiful supply of clean, safe water to come out.
Public water systems in Missouri face increasingly complex challenges, and overall have an extraordinary compliance record. Each water system is responsible for monitoring conditions at individual water plants and is required to employ trained certified operators. Water systems in Missouri are required to regularly sample water for many different contaminants following federal and state limits. A state-approved laboratory must analyze these samples and the results must be reported to the department. The majority of testing is done at the Department of Natural Resources’ and the Department of Health and Senior Services’ labs, at no cost to the systems, saving the consumers money.
