A recent report from Iowa State University argues that removing nutrient pollution from Iowa’s water would provide economic benefits for the state.
Economists with ISU’s Center for Agricultural and Rural Development (CARD) first summarize the cost of nutrient pollution in Iowa’s waterways. They write that forty-nine public water systems treat water for nitrate pollution either by using nitrate removal equipment or blending the water; these systems serve more than 10 percent of Iowa citizens. The report estimates that Iowa’s public water systems have paid $1.8 million to treat nitrate in the water since 2000.
Smaller communities and rural areas are disproportionately affected by the economic consequences of polluted water. Many small town public water systems do not have the resources to purchase costly nitrate removal equipment and as a result, may not be able to meet the U.S. Environmental Protection Agency’s water quality regulations. Private wells go largely unregulated, so consumers are responsible for picking up the water treatment costs. Findings suggest that as many as a quarter of Iowa’s wells have unsafe nitrate levels in them.
The report also comments on the lost revenue from water recreation income for the state. The number of beaches and waterways under advisory or closed each summer because of harmful algae blooms, which are fed by nitrate, continues to grow. Economists estimate that improving water quality in Iowa’s lakes by meeting Nutrient Reduction Strategy goals would increase recreational benefits for all Iowans by $30 million per year.
Iowa Legislators recently passed a bill that will allocate $282 million to water quality improvement projects in the state over the next 12 years. Critics recognize, however, that scientists with the Nutrient Reduction Strategy have estimated that it will cost billions of dollars to adequately remove nutrient runoff from waterways in Iowa.
