Part of any healthy diet is getting plenty of water each day. The group behind Iowa Source Water Protection Week is the Iowa Source Water Ag Collaborative, a group that highlights efforts for successful drinking water protection and supports locally-led work to protect sources of drinking water for Iowans.
According to the Iowa Department of Natural Resources, the term source water is used to define drinking water in its original environment, either as surface water rivers, streams, reservoirs, lakes or as groundwater aquifersbefore being withdrawn, treated, and distributed by a water system. Source Water Protection SWP is the act of preventing contaminants from entering public drinking water sources. Iowa communities are creating SWP plans to help guard the source of their drinking water, whether an aquifer, lake or river.
Communities work with a regional SWP coordinator and Iowa Source Water Ag Collaborative partners to learn about resources that can help protect their drinking water sources. The EPS team has written watershed plans that recommend ways to improve water quality within a priority watershed, which in turn, may improve the quality of source water for communities. Using cover crops and reduced tillage, installing bioreactors, saturated buffers and wetlands, each help to improve water quality within a watershed.
The Iowa Source Water Ag Collaborative offers a few examples why clean source water is important to Iowa communities and what some are doing to improve the water quality of their source. In Griswold, a local effort resulted in an SWP plan and grant dollars to add cover crops on 75 percent of the area surrounding the municipal wells. Wetlands reduce the risk of nitrate entering in the groundwater, provide wildlife habitat, and create an outdoor classroom for a nearby elementary school.
To address aging infrastructure and scarce resources, many Iowa communities are developing SWP plans that when implemented will reduce treatment costs for their drinking water.
Other communities that are developing or implementing their plans include: The Iowa Source Water Ag Collaborative is ready to partner with these communities to coordinate and develop resources. For more information on source water protection in Iowa, visit www.
