Why Did Lake Erie Become Polluted? Lake Erie’s algae blooms are caused by runoff pollution. This type of pollution occurs when rainfall washes fertilizer and manure spread on large farm fields into streams that flow into Lake Erie. This fuels a bumper crop of algae each year that can make water toxic to fish, wildlife,
How Does Runoff Affect The Rate Of Erosion? As storm water runoff water moves down a slope, it increases in velocity and increases the potential for erosion. The volume of sediment also increases because the transported particles scour and dislodge more soil particles. Rill erosion is another form of overland erosion. Does the runoff cause
What Factor Affects The Amount Of Runoff That Occurs In An Area? The principal climatic factors that affect the amount of runoff for a given watershed are rainfall duration and intensity, the season of the year, and the meteorologic and frozen soil conditions before the storm. Total runoff for a storm is related to the
How Do You Control Fertilizer Runoff? When you apply fertilizer to your lawn, use a slow-release fertilizer. Slow-release fertilizers supply a steady amount of nutrients across the growing season and help reduce fertilizer runoff. Apply a slow-release fertilizer in spring, so it can release nutrients while the grass is actively growing and absorbing them. How
How Does Fertilizer Runoff Affect Water? When manure or commercial fertilizers enter surface water, the nutrients they release stimulate microorganism growth. The growth and reproduction of microorganisms reduce the dissolved oxygen content of the water body. Without sufficient dissolved oxygen in surface water, fish and other aquatic species suffocate. How does runoff fertilizer affect oceans?
Why Runoff Is Harmful To Streams And Watersheds? Stormwater runoff can push excess nutrients from fertilizers, pet waste and other sources into rivers and streams. Nutrients can fuel the growth of algae blooms that create low-oxygen dead zones that suffocate marine life. Stormwater runoff can push excess sediment into rivers and streams. How does runoff
Are All The Great Lakes Polluted? Are all the great lakes polluted? water. Pollutants Which Great Lake is least polluted? Lake Superior has the largest volume of all the Great Lakes. It is the coldest and deepest and because it has a cooler climate and poor soil conditions it is the least polluted. Which Great
How Can Stormwater Cause Health Risks? Impervious surfaces also lead to pooling of stormwater, increasing potential breeding areas for mosquitoes, the disease vectors for dengue hemorrhagic fever, West Nile virus, and other infectious diseases. Why is stormwater harmful? Stormwater runoff can cause a number of environmental problems: Fast-moving stormwater runoff can erode stream banks, damaging
