Abstract San Francisco Bay Area water pollution is a serious problem. The sources of pollution include mercury contamination, pesticide pollution, and storm drain runoff. Water runoff is causing oil, trash, pesticides, and murcury to travel from urban and industrial areas into the bay. Mercury is a harmful neurotoxin that is harmful for developing fetuses and young children. Pesticides are used to kill unwanted pests, but are polluting the water with toxic chemicals that can have large halflifes, which means they stay in the water many years causing harm to plants and animals who depend on fresh water to survive.
In South Africa water is used out to its limit, the pollution comes from traffic associated with crude oil transport from the Arabian Gulf which is contaminated from tanks that spill oil. Some ways we pollute the Everglades, is because of some of the stuff that goes down the drains. Most of the stuff goes into a lake, pond, or canal, most these are connected to the ocean and Everglades. We have to watch what we let go down the drains, such as chemicals, and trash. I think if we make a way where trash that goes down a drain can be separated from the water and goes into another drain leading to a dump.
Water Quality and Contamination Report 1 Schrita Scott Water Quality and Contamination SCI207: Dependence of Man on the Environment Instructor Carrie Myers February 25, 2014 Water Quality and Contamination Report 2 Water Quality and Contamination Introduction: When it comes to water quality and contamination, first and foremost ground water is present below the surface in porous rocks and is prone to contamination by natural and human activities. Large amounts of chemicals like soap, detergents, fertilizers, pesticides, and pharmaceutical are often times discharged into fresh water aquifers almost daily. These contaminants leak into the soil in which it then dissolves into ground water. Different contaminants have different rates of solubility and degradation once they reach the underground water table, either by simple flow or by the downward movement of rain water. The ground water may become contaminated with both organic and inorganic substances which may include heavy metals like Cadmium, Chromium and Nickel, etc.
Explain why oil exploration in the areas shown could lead to high economic and environmental costs. (10) The environmental effects of oil exploitation in these areas can vary depending upon the type, position and severity, however most pose the threat of being potentially severe. The explorations are taking place in deep water areas such as the Gulf of Mexico, the North Sea or the Arctic. Just one of the many potential risks and dangers of deep sea drilling is highlighted by the horizon oil rig spill of oil extracted from the sea floor. A spill in any of the deep sea areas would reduce the biodiversity of that area through reductions of bird populations, fish-stocks and populations of marine mammals.
These runoffs have contributed to the beach closures, and the unsustainable condition of biological life in the lake. Human health is at great risk due to the untreated waste that is dumped in Lake Huron each year. The untreated sewage contains many viruses, two being Giardia (an intestinal parasite), cryptosporidium, which causes intestinal illnesses and even death. E. coli a more familiar virus has elevated its concentrations in Lake Huron, found in either animal or human feces, which causes diarrhea, nausea, and stomach cramps. ("Testing the waters,"
A site can only go through fracking 18 times. That means for each site 72 trillion gallons of water are used and 360 billion gallons of chemical. A majority of the water used during fracking we will never be able to use again. As of how fracking is done now, I see it as a more negative things then positive. Maybe in years to come we can find a new and less harmful way to get natural
The procedure consists of injecting a special fluid made up of chemicals and sand into the ground at high pressures to squeeze the natural gas back up through the rocks. By injecting this certain fluid we are leaving mercury, lead, hydrochloric acid, methane, and other poisonous chemicals left to rest in our earth’s crust. Studies show that more than 90% of fracking fluids are left underground. Because we are permanently polluting our land we are putting our environment at high risks of becoming destroyed and it is effecting human health. One resource that is at high risk of being contaminated due to fracking is water.
It was literally a dumping ground and it even caught on fire a few times due to the toxic wastes. The phosphorus levels in Lake Erie are increasing due to the pollution causing harm to the fishes that reside in it. In 2014, Lake Erie had so much algae from pollution that it caused the City of Toledo to be left without fresh water. This algae was caused by the excessive amount of phosphorus in the lake. This excessive amount of Phosphorus is caused when the fertilizer is dumped into the lake by farmers.
As a result, many trucks have to travel to and fro the mining site to supply the water and other amenities causing dust pollution and soil erosion on the dirt roads. Chemicals used in the fracking process are able to sip through cracks in the rocks and the soil and contaminate any water sources they meet. This water finds its way into the community or cities. When consumed, these chemicals can lead to cancer, defects in newly-born babies and disorders in the nervous system. Large amounts of methane and other poisonous gases released into the air from the gas wells contribute to heavy air pollution and global warming.
For many decades, water pollution has been a major environmental issue. "Water pollution is the contamination of water bodies and occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds" (Wales). Lake Huron, which is known as the third largest of the lakes by volume of Great Lakes, (Lakes Huron) water quality has been of major concern. Few major sources identified were faulty septic systems and agriculture. Some of the effects caused by the pollution included: disruption of aquatic life, elevated levels of nitrates and phosphates from polluted underground water, swimming prevention, and numerous outbreaks of Avian Botulism.
