What chemicals are in stormwater?

Nutrients, heavy metals, bacteria, chlorophenols, and polycyclic aromatic hydrocarbons (PAHs) are commonly reported in stormwater runoff.

What are 8 examples of runoff pollutants?

Stormwater runoff collects an often-toxic mix of pollutants including:

  • Trash.
  • Soil and sediment.
  • Fecal bacteria.
  • Nitrogen and phosphorus.
  • Oil and other petroleum products.
  • Pesticides and herbicides.
  • Road salt.
  • Toxic metals including copper, lead, and zinc.

What causes stormwater pollution?

When it rains, stormwater picks up whatever is in the street: trash, oil, waste, fertilizers, pesticides, chemicals, pet waste, and sediment.

What are the four sources of stormwater?

The major sources include contaminants from residential and commercial areas, industrial activities, construction, streets and parking lots, and atmospheric deposition.

What is stormwater runoff pollution?

Anything dumped or dropped on the ground or in the gutter can end up in the nearest body of water. Stormwater pollution results from materials and chemicals washed into the storm drains from streets, gutters, neighborhoods, industrial sites, parking lots and construction sites.

What are the source of pollutants?

Types of Sources 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.

What are 5 ways humans pollute groundwater?

Industrial discharges, urban activities, agriculture, groundwater pumpage, and disposal of waste all can affect groundwater quality. Contaminants can be human-induced, as from leaking fuel tanks or toxic chemical spills.

What are the types of water pollution?

Here’s a quick rundown of the different types of water pollution currently compromising the quality of H0 all over the globe.

  • Chemical pollution.
  • Groundwater pollution.
  • Microbiological pollution.
  • Nutrient pollution.
  • Oxygen-depletion pollution.
  • Surface water pollution.

What pollutants are carried with the rainwater running off from urban surfaces give some examples?

The stormwater runoff carries pollutants such as oil, dirt, chemicals, and lawn fertilizers directly to streams and rivers, where they seriously harm water quality.

What are 5 ways humans pollute runoff?

Stormwater runoff pollution and how to reduce it

  • Oil, grease, metals and coolants from vehicles;
  • Fertilizers, pesticides and other chemicals from gardens and homes;
  • Bacteria from pet wastes and failing septic systems;
  • Soil from construction sites and other bare ground;
  • Soaps from car or equipment washing; and.

What are the five pollutants?

The common air pollutants are:

  • Particulate matter (PM10 and PM2.
  • Ozone (O3)
  • Nitrogen dioxide (NO2)
  • Carbon monoxide (CO)
  • Sulphur dioxide (SO2)

What are the major pollutants of water?

The main water pollutants include bacteria, viruses, parasites, fertilisers, pesticides, pharmaceutical products, nitrates, phosphates, plastics, faecal waste and even radioactive substances. These substances do not always change the colour of the water, meaning that they are often invisible pollutants.
