Why is runoff a health concern?
Stormwater carries disease-causing bacteria and viruses. Swimming in polluted waters can make you sick. ... Illnesses generally associated with swimming in water contaminated with urban runoff include earaches, sinus problems, diarrhea, fever and rashes. Polluted stormwater can also hurt aquatic life.
Why is stormwater runoff bad?
Stormwater runoff can cause a number of environmental problems: Fast-moving stormwater runoff can erode stream banks, damaging hundreds of miles of aquatic habitat. ... Stormwater runoff can push excess sediment into rivers and streams. Sediment can block sunlight from reaching underwater grasses and suffocate shellfish.
Where does stormwater runoff go?
Most Stormwater Runoff flows either: directly into streams, rivers, ponds, lakes and wetlands or down the nearest Storm Drain and then into the nearest waterway without any treatment.
Is stormwater treated before entering US waters?
Storm sewer flows are not treated. Water that flows down driveways, streets, and outside areas into a storm sewer or ditch flows directly to nearby creeks, fish and wildlife habitats, downstream recreational areas, and drinking water supplies.
What is the difference between runoff and groundwater?
The main difference between groundwater and runoff is runoff refers to water that stays on the Earth's surface, while groundwater is located...
What is toxic runoff?
Toxic runoff can pollute surface waters, like rivers and lakes, as well as seep into underground groundwater supplies. Photograph by James P. Blair. Stormwater Runoff. Stormwater runoff is the runoff drained into creeks, bays, and other water sources after a storm.
Is storm drain water treated?
Stormwater is Not Treated? That's right! The storm drainage system carries rainwater directly to creeks, streams, ponds and reservoirs. That is why it's important to keep trash, motor oil, pesticides, and other chemicals from entering the storm drain – everything that goes in comes out in our waterways.
Where does most stormwater runoff eventually end up?
Where does most stormwater runoff eventually end up? Most stormwater runs into small bodies of water, like creeks and streams, although it will likely head to whatever water source is close by. Eventually, that water will travel to other larger bodies of water, like river, lakes, or oceans.
How does stormwater pollute drinking water?
When rainwater can't soak into the ground, it runs along streets and parking lots and picks up pollutants. This polluted runoff can flow into our rivers and streams, or overwhelm local infrastructure to cause sewage overflows. ... Sewage carries pathogens that can end up in our drinking water supplies and swimming areas.
Why does LA have storm drains?
When it rains up high in the mountains that ring the Los Angeles Basin, the water flows downhill, first in tiny rivulets, and then making its way into larger and larger creeks. ... This water is typically cleaner than water that flows into the river from city streets and storm drains (more on this later).
What problems do you think can occur when there is too much runoff on the ground?
Some other effects from stormwater runoff include:
Property damage. Flooding has increased in some areas because water can't soak slowly into the ground. Instead it runs off hard surfaces and, in a heavy rain, can lead to flooding, erosion and property damage. Water pollution.
Where does water from home drains end up?
Water leaving our homes generally goes either into a septic tank in the back yard where it seeps back into the ground, or is sent to a wastewater-treatment plant through a sewer system.
How many storm drains are in the US?
About 860 communities in the US have combined sewer systems, serving about 40 million people.
