What are 2 different types of water pollution?
The main types of water pollution include groundwater pollution, surface water pollution, suspended matter, oil spillages, microbiological pollution, chemical water pollution, thermal pollution, and oxygen-depletion pollution. All of these can cause pollutants and contaminants to enter our waterways.

What are the four main causes of pollution in the United States and Canada?
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.
What is the most polluted water in the US?
The Mississippi River
The Mississippi River
This once pristine waterway is perhaps the most polluted in the United States. Part of the problem stems from agriculture. The Mississippi River traverses much of America’s heartland, drawing no end of runoff from factory farms. Animal waste isn’t the only problem.
What is the biggest cause of pollution in Canada?
Key drivers of air pollution
The growth in Canada’s population and economy increases the demand for the production and delivery of goods and services, transportation and housing. Most of the energy used to meet this demand still comes from fossil fuels, which impacts the quality of the air we breathe.
What are the 3 major pollution issues in Canada?

Where is the most polluted water in Canada?
Two regions – Eastern Lake Huron and the Lake Ontario and Niagara Peninsula subwatershed – share the dubious distinction of being the most disturbed in Canada because of a combination of seven threat factors, including high pollution levels, water use and fragmentation, among others shown in the accompanying maps.
What are the 3 main types of water pollution?
Water pollutants can be divided into three major categories: (1) substances that harm humans or animals by causing disease or physical damage; (2) substances or situations that decrease the oxygen content of water, leading to anaerobic decay and the death of aquatic life; and (3) substances that are indirectly harmful,
What are the top 3 causes of pollution?
What are the top 10 causes of Pollution?
- Burning of Fossil Fuels – such as coal, oil, gasoline to produce energy for electricity or transportation.
- Automobiles – gases emitted from vehicles.
- Agricultural Activities – the insecticides, pesticides and fertilizers emit harmful chemicals.
What is the number 1 cause of pollution?
Household combustion devices, motor vehicles, industrial facilities and forest fires are common sources of air pollution. Pollutants of major public health concern include particulate matter, carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide.
What is the main pollution in the US?

How does water pollution affect the United States?
If drinking water contains unsafe levels of contaminants, it can cause health effects, such as gastrointestinal illnesses, nervous system or reproductive effects, and chronic diseases such as cancer.
What is the largest contributor to pollution in the US rivers?
Agricultural Runoff is one of the leading causes of water pollution in the United States. Current agricultural practices lead to nutrient loading and in turn to eutrophication. One of the main problems in attempts to regulate this type of pollution is that it is non-point source.
