Environmental Protection Commission Visits Des Moines Water Works

photo 2On August 20, the Iowa Environmental Protection Commission (EPC) held their regularly scheduled monthly meeting at Des Moines Water Works (DMWW). Prior to the business meeting, Commissioners Couser, Rastetter, Sinclair, Smith, and Ver Steeg, Iowa Department of Natural Resources (IDNR) staff, and representatives from environmental and agricultural organizations toured Des Moines Water Works’ Fleur Drive Treatment Plant to gain a better understanding of the treatment process. DMWW staff provided the Commissioners an insight into the condition and challenges of source waters used for drinking water for the more than 500,000 people in central Iowa.

Challenges expressed by DMWW included everything from high nitrates to flood events. However, most questions and comments stemmed from the exceptionally high nitrate levels this year. DMWW staff emphasized that even if nitrate levels are currently low, the combination of nitrates and phosphorus in the rivers and increasing temperatures will again challenge DMWW due to algae blooms. Algae can cause taste and odor problems and require additional filter maintenance, which slows the treatment process and reduces production capacity.

The EPC is a panel of nine citizens who provide policy oversight over Iowa’s environmental protection efforts. EPC members are appointed by the Governor and confirmed by vote of the Senate for four year terms.
