Which of these are the two major sources of nitrate pollution in rivers?
- the burning of fossil fuels by factories and cars
- animal wastes and fertilizers
- fertilizer runoff and the burning of fossil fuels by factories
Answer
According to an EPA study, animal wastes and fertilizer runoff are the two major sources of nitrate pollution.
Animal waste can pollute our waterways when manure is not managed properly. There are various ways that homes, yards, and streets can contribute to nitrogen pollution, but there are also solutions to address this pollution at its source.
What is Nitrate Pollution in Rivers?
Nitrate pollution in rivers is a growing problem in the United States. High levels of nitrates in water can cause serious health problems for people and animals. Nitrates can come from agricultural and urban runoff. When these sources of pollution mix with groundwater or surface water, it can create problems for drinking water, recreation, and aquatic life.
What Are The Health Effects of Nitrate Pollution?
Exposure to high levels of nitrates in drinking water can cause serious health problems, including cancer. Infants and young children are especially vulnerable to nitrate poisoning, which can lead to death. Nitrates can also cause problems for people with diabetes, heart disease, and other health conditions.
What Can I Do To Reduce Nitrate Pollution?
There are various ways that homes, yards and streets can contribute to nitrogen pollution. Here are some things you can do to reduce your impact:
- Use less fertilizer on your lawn and garden.
- Sweep up leaves and grass clippings from the street.
- Pick up after your pet.
- Dispose of household hazardous wastes properly.
- Use phosphate-free detergents.
These are just a few things you can do to reduce nitrate pollution. For more information, contact your local water utility or EPA office.
