Effects “Pollutants are harmful to both humans and animals “Pollutants are harmful to both humans and animals May not effect us instantly, though if exposed to them over a long period of time they will cause major harm to our health May not effect us instantly, though if exposed to them over a long period of time they will cause major harm to our health Heavy metals from industrial processes can accumulate in nearby lakes and rivers. These are toxic to marine life such as fish and shellfish, and subsequently to the humans who eat them. Heavy metals can slow development; result in birth defects and some are carcinogenic. Heavy metals from industrial processes can accumulate in nearby lakes and rivers. These are toxic to marine life such as fish and shellfish, and subsequently to the humans who eat them. Heavy metals can slow development; result in birth defects and some are carcinogenic. Industrial waste often contains many toxic compounds that damage the health of aquatic animals and those who eat them. Some of the toxins in industrial waste may only have a mild effect whereas other can be fatal. They can cause immune suppression, reproductive failure or acute poisoning.

Microbial pollutants from sewage often result in infectious diseases that infect aquatic life and terrestrial life through drinking water. Microbial water pollution is a major problem in the developing world, with diseases such as cholera and typhoid fever being the primary cause of infant mortality.” Microbial pollutants from sewage often result in infectious diseases that infect aquatic life and terrestrial life through drinking water.

Effects continued… “Organic matter and nutrients causes an increase in aerobic algae and depletes oxygen from the water column. This causes the suffocation of fish and other aquatic organisms. “Organic matter and nutrients causes an increase in aerobic algae and depletes oxygen from the water column. This causes the suffocation of fish and other aquatic organisms. Sulfate particles from acid rain can cause harm the health of marine life in the rivers and lakes it contaminates, and can result in mortality. Sulfate particles from acid rain can cause harm the health of marine life in the rivers and lakes it contaminates, and can result in mortality. Suspended particles in freshwater reduces the quality of drinking water for humans and the aquatic environment for marine life. Suspended particles can often reduce the amount of sunlight penetrating the water, disrupting the growth of photosynthetic plants and micro-organisms.

Methods and technologies used to control land and water pollution there are three stages which raw sewage goes through in a water treatment plant. Industrial Treatment: there are three stages which raw sewage goes through in a water treatment plant. 1. Primary stage where solids and inorganic materials are removed through filters. 1. Primary stage where solids and inorganic materials are removed through filters. 2. Secondary stage where organic material is reduced through biological filters. 2. Secondary stage where organic material is reduced through biological filters. 3. Tertiary stage where chemicals are added which help to get rid of other impurities. 3. Tertiary stage where chemicals are added which help to get rid of other impurities.

Solid particles sink to the bottom and soap and lighter particles rise to the top. Biological processes filter the wastewater Biological processes filter the wastewater The liquid then flows out and the solids break down further The liquid then flows out and the solids break down further

Methods and technologies used to control land and water pollution continued… Denitrification is an ecological approach that can be used to prevent the leaching of nitrates in soil, this in turn stops any ground water from being contaminated with nutrients. Denitrification is an ecological approach that can be used to prevent the leaching of nitrates in soil, this in turn stops any ground water from being contaminated with nutrients. Fertilizers contain nitrogen, and are often applied to crops by farmers to help plant growth and increase the yield. Fertilizers contain nitrogen, and are often applied to crops by farmers to help plant growth and increase the yield. Bacteria in the soil convert the nitrogen in the fertilizer to nitrates, making it easier for the plants to absorb. Bacteria in the soil convert the nitrogen in the fertilizer to nitrates, making it easier for the plants to absorb. Immobilization is a process where the nitrates become part of the soil organic matter. Immobilization is a process where the nitrates become part of the soil organic matter. When oxygen levels are low, another form of bacteria then turns the nitrates into gases such as nitrogen, nitrous oxide and nitrogen dioxide. When oxygen levels are low, another form of bacteria then turns the nitrates into gases such as nitrogen, nitrous oxide and nitrogen dioxide. The conversion of these nitrates into gas is called denitrification. This prevents nitrates from leaching into the soil and contaminating groundwater.

Environmental Protection Agency Clean Water Act, 1972 Clean Water Act, 1972 Regulates both pollution discharges and quality standards for surface waters Regulates both pollution discharges and quality standards for surface waters The basis of CWA was the 1948 Federal Water Pollution Control Act The basis of CWA was the 1948 Federal Water Pollution Control Act Wastewater standards for industries and water quality standards for all contaminants in surface waters Wastewater standards for industries and water quality standards for all contaminants in surface waters National Pollutant Discharge Elimination System (NPDES) permit program controls discharges National Pollutant Discharge Elimination System (NPDES) permit program controls discharges Industrial, municipal, animal feeding operations and other facilities must obtain permits if their discharges go directly to surface waters Industrial, municipal, animal feeding operations and other facilities must obtain permits if their discharges go directly to surface waters The Total Maximum Daily Load provisions of the Clean Water Act help protect the quality of the surface-water resources.

“The Nonpoint Source Program (Section 319) requires States to develop nonpoint-source management programs. Nonpoint-source control plans can include State regulatory measures, but usually emphasize voluntary actions like those used in USDA conservation programs. Implementation grants to States and tribes ($200 million in FY2008) fund projects like installation of best management practices (BMPs) for animal waste; design and implementation of BMP systems for stream, lake, and estuary watersheds; and basinwide landowner education programs.” http://www.ers.usda.gov/Briefing/AgAndEnvironment/federallaws.htm

Article 19: How Much is Clean Water Worth? From when this article was written to now, how much do you think peoples viewpoints have changed in regards to ecosystem services, if at all? From when this article was written to now, how much do you think peoples viewpoints have changed in regards to ecosystem services, if at all? “Although ecosystem services have been with us for millennia the scale of human activity is now sufficiently great that we can no longer take their continuation for granted (Heal, How Much is Clean Water Worth?).” “Although ecosystem services have been with us for millennia the scale of human activity is now sufficiently great that we can no longer take their continuation for granted (Heal, How Much is Clean Water Worth?).” http://funnytogo.com/pictures/pollution/water/fish.gif
