As stormwater runoff collects debris and pollutants from the surrounding area, it travels toward many animals' natural habitats such as a lake or ocean. These substances are often toxic to wildlife and can lead to their death. Even minute amounts of substances can affect wildlife.

How does runoff affect aquatic life?
Urban runoff has a detrimental effect on aquatic animals and organisms. Many contaminants can sicken and kill off fish, coral and other aquatic animals. Other contaminants can lead to algae blooms which can also reduce the populations of necessary organisms.
What are the effects on animals in the waters affected by the farm runoff?
It can also clog the gills of fish or smother fish larvae. In addition, other pollutants like fertilizers, pesticides, and heavy metals are often attached to the soil particles and wash into the water bodies, causing algal blooms and depleted oxygen, which is deadly to most aquatic life.
What can runoff affect?
Runoff picks up fertilizer, oil, pesticides, dirt, bacteria and other pollutants as it makes its way through storm drains and ditches - untreated - to our streams, rivers, lakes and the ocean. ... Reduce flooding - When heavy rain falls, the runoff that flows into the street can back up and cause street flooding.
How does runoff affect salmon?
In a controlled experiment, the coho salmon nearly died within hours of exposure to stormwater runoff, the study finds. The heavy metals and toxins in the stormwater poison the fish, making it difficult for them to breathe.
Why is runoff bad for the ocean?
Runoff is a major source of water pollution. As the water runs along a surface, it picks up litter, petroleum, chemicals, fertilizers, and other toxic substances. From California to New Jersey, beaches in the U.S. are regularly closed after heavy rainfall because of runoff that includes sewage and medical waste.
How does pollution runoff impact the world's oceans?
Our ocean is being flooded with two main types of pollution: chemicals and trash. ... The increased concentration of chemicals, such as nitrogen and phosphorus, in the coastal ocean promotes the growth of algal blooms, which can be toxic to wildlife and harmful to humans.
How do animals pollute water?
Grazing animals and pasture production can negatively affect water quality through erosion and sediment transport into surface waters, through nutrients from urine and feces dropped by the animals and fertility practices associated with production of high-quality pasture, and through pathogens from the wastes.
How does stormwater runoff affect water quality?
Stormwater runoff can push excess nutrients from fertilizers, pet waste and other sources into rivers and streams. ... Stormwater runoff can push pesticides, leaking fuel or motor oil and other chemical contaminants into rivers and streams. Chemical contaminants can harm the health of humans and wildlife.
How does erosion affect water quality?
The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
What are the negative impacts of runoff on the environment?
Uncontrolled stormwater runoff has many cumulative impacts on humans and the environment including: Flooding - Damage to public and private property. Eroded Streambanks - Sediment clogs waterways, fills lakes, reservoirs, kills fish and aquatic animals. Widened Stream Channels - Loss of valuable property.
What does pollution do to salmon?
Pollution from car tires that washes into waterways is helping cause a mass die-off of salmon on the US west coast, researchers have found. In recent years, scientists have realized half or more of the coho salmon, also known as silver salmon, returning to streams in Washington state were dying before spawning.
How does pollution affect salmon?
Pollution comes in many forms. Erosion from logging and development washes into streams, covering salmon eggs and suffocating them. ... Rivers may become slow and warm when water is withdrawn for farming and other uses, making them unhealthy for salmon.
How are humans harming salmon?
pollution. using artificial means to help salmon reproduce and grow. taking salmon out of the water to transport them on a boat or truck. releasing salmon into the sea after raising them in hatcheries.
What is runoff and factors affecting runoff?
Runoff depends on the intensity of rainfall. More the rainfall, more will be runoff. If the rainfall intensity is very less and it rains as light showers then much of the water will be lost in infiltration & evaporation resulting less runoff. If precipitation is in case of snow then less runoff.
Who pollutes the ocean the most?
China, Indonesia top the trash tally.
More plastic in the ocean comes from China and Indonesia than anywhere else — together, they account for one-third of plastic pollution. In fact, 80 percent of plastic pollution comes from just 20 countries, including the United States.
How does agricultural runoff affect the ocean?
When large tracts of land are plowed, the exposed soil can erode during rainstorms. Much of this runoff flows to the sea, carrying with it agricultural fertilizers and pesticides. ... Much of this, too, makes its way to the sea. Some water pollution actually starts as air pollution, which settles into waterways and oceans.
