...WATER QUALITY AND CONTAMINATIONS PG. 1 Water Quality and Contamination Nalissa Johnson SCI207: Dependence of Man on the Environment Otishna Jacobs 16 August 2015 WATER QUALITY AND CONTAMINATIONS PG. 2 Introduction Ground water is the biggest source of drinking water available to human population around the world and is rapidly being polluted because of industrialization and increasing demands of agriculture around the world. “Ground waters frequently contain iron, manganese and ammonium above the allowed concentration levels for drinking water”(Strembal, 2004)There are a lot of dangers associated with drinking or cooking with contaminated water. Diseases, poisons, and toxins can be found in contaminated water. There is also a possible correlation between an increased cancer risk and consuming contaminated water. “Being out of sight, it is not always apparent that damage has been, or is being, done to the groundwater resources. The need to prevent groundwater pollution is important because of the very high proportion of groundwater resources that are used for potable supply.” (Helmer, 1997) The objective of the first experiment we conducted was to test the ability of soil to remove oil, vinegar, and laundry detergent from the environment before it reaches ground water. We want to know this because often we...

The sewage treatment plant adds back into the ground water table at that spot. The filtration pumps ensure your water will not get polluted from the ground pollution that occurs. When using this trick, you can pick one of the four clustered cities in your tradable region to keep using the trick repeatedly. This will provide a massive amount of water that can be purchased. You can then buy from that massive source while building the other three cities. This will save you the need to place a water source and sewage treatment plant.

The Chesapeake Bay is approximately 200 miles in length and it has a width which ranges from 3.4miles to 35miles. The Chesapeake Bay watershed has so much research done on it in order to figure out strategies to revive it. 2. The Chesapeake Bay Program is a regional partnership that leads and directs protection and restoration of the Chesapeake Bay. Although the Chesapeake program partners have mutual restorative objective, they tend to implement restorative actions based on their resources. Their restorative objective include but not limited to * Reducing Pollution * Restoring Habitats * Managing Fishery * Protecting Watershed * Fostering Stewardship 3. Point source nutrient loading is a form of pollution which can be easily regulated because the nutrients are known to originate from a specific location. However in a non-point source nutrient loading the nutrient’s origin is not easily identified, which makes this kind of nutrient loading difficult to contain. 4. The greatest contributor of nutrient loading in the bay is agricultural run-offs. 5. Eutrophication is the enrichment of the ecosystem with chemical substances such as nitrogen and/or phosphorous. It can also be said to be the ecosystem’s reaction to the introduction of natural and artificial substances into aquatic habitats. An excess amount of nutrient loading fuels...

...WATER POLLUTION Effects of water pollution Contaminated Drinking Water. The risks of your health being negatively impacted by polluted drinking water in a developed country is small in comparison with developing countries. However, it is possible to become ill from contaminated water. When you are out hiking, you can acquire giardiasis that can lead to the presentation of acute symptoms like vomiting and intense nausea. This infection is caused by drinking water that has been fouled by animal wastes in untreated waterways. In anthropogenic environments like cities and towns, the potential toxins are far more numerous. Mercury Level Risks . Health risks from pollution vary from area to area. One of the most pervasive non-localized water pollution issues facing the world today is the level of mercury in the oceans. Inorganic mercury is a common byproduct of a number of industrial processes. The level of mercury in fish is mostly dangerous for small children and women who might become pregnant, are pregnant or are nursing. Mercury has been found to interfere with the development of the central nervous system in fetuses and young children, which could potentially lead to a large amount of long-term side effects. Health Effects of Toxic Runoff . In Louisiana, water quality can be so bad in many waterways that fish advisories are often posted to warn people against eating fish out of contaminated waterways. This is largely due to industrial runoff from localized sources and the...

...Hypothesis I will investigate whether the concentration of oxygen in pond water will affect the abundance of Phantom Midge Larvae (Genus Chaoborus) by comparing a pond that has a higher oxygen concentration with a pond that has a lower oxygen concentration. Alternative Hypothesis: The lower the oxygen concentration, the higher the abundance of Phantom Midge Larvae. Null Hypothesis: There will be no significant difference between the oxygen concentration and the abundance of Phantom Midge Larvae. Any difference is due to chance. Research The Phantom Midge Larvae (Genus Chaoborus) A phantom Midge Larvae (Genus Chaoborus) otherwise known as a ‘glassworm’ due to its transparent appearance is a form of Midge Larva which are very abundant in static water such as ponds and lakes. The body is in distinct segments with small hairs and the last segment has a number of stiff hairs which acts as a rudder. They breathe through the end of their abdomen and have two small eyes on the front of their body. They can survive is polluted waters with little oxygen. Unlike other air filled invertebrates, the Phantom Midge Larvae has two visible black air sacs either side of their body which allows them to migrate up and down in static water. They can be found in waters as deep as 70m where there is little oxygen and they are able to avoid predators which are found in shallower waters. Phantom Midge Larvae are consumed by other aquatic predators such as puffers, young cichlids and bumblebee...

...Water Quality and Contamination Lab Report Kathryn Thomas SCI207: Dependence of Man on the Environment Instructor Joseph Fiedor October 6, 2014 Water Quality and Contamination Lab Report Abstract The water filtration process was examined using oil, vinegar, and detergent to show how well the process works. The watercolor, consistency, and smell would change allowing the difference to be seen. Different kinds of water were tested using test chemical strips to evaluate the chemicals within them. The reason was to show that bottled water was not better for human consumption than tap water. Contaminants can be carried from one point to another and can affect human health. Water quality is very important and knowledge gained in our communities can make a difference. Introduction Water quality research is important because it helps to protect and restore the quality of the Nation’s water. Certain standards help to identify problems caused by incorrectly treating wastewater, sediment, fertilizers, and chemical from agricultural areas. Standards are put in place to achieve and preserve protective water quality conditions. (EPA, 2012). Water quality affects ecological processes such as good river health, vegetation, wetlands, and birdlife. Our water resources have major environmental, social, and economic values. If the water quality is not maintained, it will affect more than the environment; it will affect commercial and recreational values as well. (NSW, 2012). The main...

...Final Lab Report Water Quality and Contamination Rachel Hewitt SCI207: Dependence of Man on the Environment Professor Andrea Van Gunst May 16, 2016 ABSTRACT All lab experiments were conducted in Windham, New York. The first experiment regarding water quality and contamination, used vinegar, liquid detergent and vegetable oil to contaminate tap water. The results of this experiment showed that when the water was contaminated and filtered through dirt some of the contaminates remained trapped in the soil and didn’t contaminate the groundwater but some did. This experiment could help in finding safer ways to purify and filter water. The results of this experiment were that the oil separated in the water and was trapped in the soil not the groundwater. The vinegar changed the smell of the water and contaminated the soil but without any major effect on the groundwater. The liquid detergent also changed the smell of the water as well as the color but also contaminated the soil and groundwater. The next experiment that was conducted was to use products like sand, charcoal and gravel to filter contaminated water that had been treated with alum. The products were used as an aquifer. The results of this experiment were basically if you used coagulants combined with alkalinity you would be able to remove contaminants from the groundwater. The last experiment bottle water and tap water were compared and tested for levels of iron, phosphate, chloride and ammonia to figure...
