The Des Moines Water Works is now considering drilling wells to find clean water. After years of lawsuits and legislative lobbying, the utility has been unable to keep farmers upstream in order to reduce runoff. These efforts have cost Water Works $18 million to treat the polluted river water over the last two decades. Resulting in the utility now planning to spend $30 million in order to drill wells which will mix in pure water when the nitrate levels rise seasonally. 

Major cities are often discouraged from taking such a dramatic measure, as reliance on wells for large populations would quickly deplete the groundwater. Comparatively, small communities may often use wells but surface sources such as rivers and lakes, supply 70% of the freshwater used in the U.S. 

Nitrate levels in central Iowa have become so bad that Des Moines Water Works’ CEO Ted Corrigan said to Iowa Public Radio “for 110 days last year [Water Works] could not use the Des Moines River as a water source…That is shocking.” 

Since many Iowa farmers are unable to privately invest in ways to filter out chemicals and public funding through the Iowa Nutrient Reduction Strategy is limited, the utility has few alternative options. 

Water Works has paid the U.S. Geological Service $770,000 to analyze drilling sites north of the city, according to The Gazette. Thereafter, the utility will have to work with state and federal agencies to get the permits to build the wells.
