I hypothesized that the Conodoguinet Creek is polluted. Through my research I have found that the Conodoguinet Creek is not polluted. One reason it is not polluted is because most of the macroinvertebrates and crustaceans we found in the creek are pollution sensitive creatures. Another reason the creek is not polluted is the level of acidity and alkalinity is 7 which is a healthy number on the pH scale. If the acidity or alkalinity levels were high scientists would have to find a way to neutralize the acid and alkaline.
There are two types of pollution common in our area, eutrophication and acid rain. Eutrophication is nutrient pollution from things like fertilizer. Fertilizers are used to aid the growth of plants, but are very harmful to water quality. Rain can wash away this fertilizer, draining it into nearby streams. The fertilizer accelerates algae growth, blocking light to good plants on the bottom.
SVN 3M The Nitrogen Cycle Name: Isabelle Rowe Go to the following website: http://nortonbooks.com/college/biology/animations/ch38a02.htm 1. What are the 2 forms of usable nitrogen? The two forms of usable of nitrogen are ammonium and nitrates. 2.
“Carried by snow melt, rain water, and groundwater, NPS pollution contributes sediments, nutrients (nitrogen and phosphorus), toxic substances, and pathogens to water bodies” (Maine Rivers 2005, ijc 2008). The Non Point Pollution generally due to stormwater in the downstream portion of the river; which are the most populated areas situated near the estuary;With the stormwater large amounts of pollutants are washed off to the river because of the impenetrable surfaces of that area which does not allow water to seep into the ground. Other sources of Nonpoint pollution are seepage from broken sewage and septic tanks, runoff from construction sites ,nutrients,sediments and chemicals from agricultural farms and roads. According to the report of International Joint Commission in 2008; “This untreated runoff may contain litter, dust, soil, oil and grease from roads, garden waste, chemicals, and nutrients and pathogens from animal feces and fertilizers” (IJC
Wastewater contributes about the third most nitrogen and phosphorus that pollutes the Chesapeake Bay. Wastewater comes from sewage treatment plants, which are point sources. Several factories and power plants also release pollutants into the water. They also release chemicals into the air, where they can fall down onto the bay and affect the organisms. Non-point source pollution harms many organisms from the substances the runoff picks up.
This policy brief examines the Water Works v. Drainage Districts legal battle from earlier this year. The Iowa Supreme Court declared that the drainage districts were not responsible for the $80 million that Water Works paid to remove excess nitrates from agricultural runoff in the Raccoon River, which supplies drinking water to half a million Iowans 2. Water Works claims that nitrate pollution from agricultural runoff in Sac, Calhoun and Buena Vista counties violated the U.S. Clean Water Act (CWA) 1. The 1972 CWA exempts runoff from farms, which are not considered as “point sources” of pollution 1. Water Works would like to see runoff from tile drainage considered as a point source, due to the pollution of groundwater which is protected
Combining the Rhetorical Modes Pollution occurs in the world naturally as well by the hand of humans. Pollution is the introduction of contaminants into the natural environment that cause adverse change. For example, when a cow passes gas a large amount of methane gas is released into the atmosphere. Methane is twenty one times more harmful to the environment than carbon dioxide, this results in the global temperature increasing. Humans contribute to pollution as well, for example, a person drives to work everyday in a car that runs on gas, the gas burning in his engine causes carbon monoxide to be released, increasing the global temperature.
A nonpoint source pollution is when the source of the pollution is discrete such as the smoke cars produce which is very harmful to the environment. As a response to this, the United States Environmental Protection Agency (EPA) has created the Clean Air Act of 1990 which strengthens the regulations pertaining air quality standards. They have set a criteria of pollutants. Carbon monoxide, sulfur dioxide, nitrogen dioxide, tropospheric ozone, particulate matter, and lead pose especially great threats to human health. For these, the EPA has established National Ambient Air Quality Standards(NAAQS) which are the maximum allowed concentrations of these pollutants in ambient outdoors.
Pollution and human impact has been wrongfully hurting West Indian Manatees The manatee is a big sea mammal that is also known as the sea cow. The manatees weigh about 650 lbs and are nearly 8.5 ft. long on average. The West Indian manatee lives in the warm waters off the coast of Florida. The West Indian manatee was placed on the endangered species list in 2016, the manatee has recently been moved to the threatened list due to the many people gathering together and to help and save the manatees.
Water contamination and pollution has been a major problem throughout the nation due to the fact that it’s being done all over. Especially of the most recent contamination in Colorado all in the Animas River from the EPA spilling. Within the last couple of month there has been a mere excessive amount of water being polluted and having toxic waste carelessly dumped. The Animas River of Colorado and flowing through Utah, New Mexico, and high Northern Part of Arizona.
A Case Study on Polluter’s Dilemma I. Background/Point of View On a small plastic manufacturing, Jonica Gunson works as an environmental compliance manager. The company where she is working with is now facing a serious situation that needs to have a fast and decisive decision, decision whether to invest or not to invest money on new technology that will help decrease or as possible eliminate the level of toxic in the water which is flowing from the back of the factory up to lake. Though the company is compliant with the levels of emissions set by the Environmental Management board, the manager sees that environmental procedures for this specific toxic are sheathing behind logical evidence, particularly that there is a protest from a certain scientist that is publish in the newspaper.
The Moon's origin is undecided due to many conflicting variables that we have discovered over the last half century. This includes a better understanding of planetary physics and the geological stages that are needed for a planet or moon to form. During Apollo 11, Neil Armstrong and Buzz Aldrin placed a large mirror on the surface. The Lunar Laser Ranging experiment involved sending a laser to the mirror and timing how long it took to receive a laser signal back. Using this time scientists could then calculate exactly how far away the moon was from the earth.
Aquatic littering can be further categorized into two main sources, namely, land-based sources and marine-based sources. Land-based sources that pollute the marine environment include local drainage systems, fleeting streams and sewage drainage. Industrial, agricultural and domestic activities also play a vital role in causing marine pollution.
• Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicles exhaust are the number one pollutants. Heavy Metals, nitrates and plastic are toxins for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins
This form of pollution has increased as the population of this town has increased. There are two different ways in which water pollution can occur: • If pollution occurs from a single location such as a discharge pipe attached to a factory it is known as point-source pollution. • A great deal of pollution happens not from one source but from many different scattered sources. This is known as nonpoint-source pollution. (Adapted from: www.explainthatstuff.com)
