Solving NPS Pollution Problems Note: Clicking on a word will take you to its definition. Hit the back button to return here. Because nonpoint source pollution is wide-spread across the state, there is no quick fix to the problem. Improving our streams and lakes requires the help of all Iowans, both urban and rural.
The main solution is prevention. That means keeping excess sediment, nutrients, bacteria and other pollutants out of our water. Because the largest problems come from agricultural areas, an important solution is using conservation practices. Common conservation practices include wetlands, ponds, terraces and buffers. These practices reduce the amount of pollutants reaching a lake or stream. While agriculture is the largest source of nonpoint pollution in Iowa, urban areas can also work to improve our water. Some urban solutions include managing lawn fertilizers, keeping pollutants out of storm drains and keeping excess soil from construction sites out of streams and lakes.
