A pond filled with plant overgrowth surrounded by treesWater is essential to all forms of life, and maintaining its quality is crucial for health, ecological balance, agriculture productivity, recreational use, industrial processes, and environmental sustainability. However, if you have been hiking or biking around Dubuque recently, you probably have noticed that much of our water has been overtaken by algae blooms, plant overgrowth, and other pollutants. Dubuque is not alone. Water quality is an issue throughout Iowa, the rest of the country, and the world.  

One of the primary goals of National Water Quality Month, observed every August, is to raise awareness about the sources and impacts of water pollution. Water pollution has two categories, point-source and nonpoint-source pollution. Point-source pollution originates from a single, direct source, such as a factory or wastewater treatment plant. Nonpoint-source pollution occurs when precipitation or irrigation water runs over land and picks up pollutants, depositing them into streams, lakes, or groundwater. This latter type, especially runoff of soil, fertilizer, and manure from agricultural land, is the most common in Iowa and is largely unregulated. This pollution reduces water clarity, fills lakes, and carries nutrients like nitrogen and phosphorus, causing harmful algae blooms that threaten drinking water, wildlife habitats, and outdoor recreation. It also includes chemicals or nitrates that leach into waterways and groundwater.

Prevention is key, focusing on keeping excess sediment, nutrients, bacteria, and other pollutants out of water. In agricultural areas, conservation practices like wetlands, ponds, terraces, and buffers are essential to reduce pollutants. Urban areas can contribute by managing lawn fertilizers, preventing pollutants from entering storm drains, and controlling soil runoff from construction sites. These efforts require not just changes in individual practices but a collective effort that addresses issues of regulation, policy, and funding.

National Water Quality Month is an ideal time to advocate for these solutions, raise awareness about the importance of water quality, and encourage practices that protect our water resources. To learn more about water quality, please visit our book display on the main floor of the Library.
