What is the meaning of nonpoint source pollution?

NPS pollution is caused by rainfall or snowmelt moving over and through the ground. Nonpoint source pollution can include: Excess fertilizers, herbicides and insecticides from agricultural lands and residential areas. Oil, grease and toxic chemicals from urban runoff and energy production.

What is agricultural water pollution?

The most prevalent source of agricultural water pollution is soil that is washed off fields. Rain water carries soil particles (sediment) and dumps them into nearby lakes or streams. Too much sediment can cloud the water, reducing the amount of sunlight that reaches aquatic plants.

What is point source pollution examples?

Examples include smokestacks, discharge pipes, and drainage ditches. Factories and power plants can be a source of point-source pollution, affecting both air and water. Smokestacks may spew carbon monoxide, heavy metal, sulfur dioxide, nitrogen dioxide, or “particulate matter” (small particles) into the air.

How does agrochemicals affect the environment?

Usually, make water unfit for humans and animals consumption. Diffusion of Agrochemicals in larger water bodies promotes the growth of algae which is again hazardous. Excess chemicals may lead to Eutrophication. Lead12 to water pollution thereby affecting aquatic habitats.

How does agrochemical affects the soil health?

Most of the agrochemicals negatively affect soil microbial functions and biochemical processes. The alteration in diversity and composition of the beneficial microbial community can be unfavorable to plant growth and development either by reducing nutrient availability or by increasing disease incidence.

What are the different sources of pollution?

mobile sources – such as cars, buses, planes, trucks, and trains. stationary sources – such as power plants, oil refineries, industrial facilities, and factories. area sources – such as agricultural areas, cities, and wood burning fireplaces. natural sources – such as wind-blown dust, wildfires, and volcanoes.

How can we prevent point source pollution?

What You Can Do to Prevent Nonpoint Source Pollution

1. Keep litter, pet wastes, leaves and debris out of street gutters and storm drains—these outlets drain directly to lake, streams, rivers and wetlands.
2. Apply lawn and garden chemicals sparingly and according to directions.

What are the negative effects of water pollution in agriculture?

The EPA has these pollutants classified as the six principal pollutants (or “criteria pollutants” – as they are also known). These pollutants are monitored by the EPA, as well as national, state and local organizations.
