...SC4730 Unit 6 Lab 1. The DC Water and Sewer Authority (DCWASA), collects waste and storm water. Once it collects the waste and storm water it puts it through a nitrification/de-nitrification, effluent filtration, chlorination/de-chlorination and post aeration process. For solid wastes, the treatment includes thickening and dewatering processes and other processes such as screen and de-gritting processes, gravity thickeners, dissolved air flotation thickeners, sludge blending centrifuge dewatering. 2. DC WASA provides training for its employees depending on the expertise in the area they work in. 3. Raw water, waste water and storm water is separated at collection to avoid contamination and overflowing 4. All primary sludge and all of the nitrification and de-nitrification waste active sludge is demolished and also lime stabilized. All waste collected by the District of Columbia sewer system, Virginia and Maryland is delivered to the Blue Plains Advance Wastewater Treatment Plant. 5. Some nontoxic sludge can be used as soil conditioner and also as fuel, since it produces methane gas. 6. Yes, the plant uses a combined sewer overflow system to collect both the waste water and storm water in parts where it’s necessary. 7. One of the challenges of treating waste water is controlling toxic chemicals through special treatments and trying to minimize the amount of nutrients such as phosphorus and nitrogen from leaking into rivers. 8...

...Emadeldin Abdalla SC4730 Environmental Science 24 April 2014 Unit#6 Lab#1 Virtual Field Trip: Sewage Treatment Plant Questions 1-15; Page 78-79: 1. How does the plant work? How does it remove solids, reduce organic matter, and restore oxygen to the water? a. It utilizes the bacteria to emulate and accelerate the natural process of human waste degradation. The wastewater flows by gravity and bar screens let water pass but not most of the trash. Two primary settling basins allow smaller particles to settle. The primary wastewater flows out to the next step. The scrapers collect the solid matter that remains. A surface skimmer collects scum or grease floating on top of the basins. 2. What training do the operators and technicians have? b. Other than a high school diploma most are trained on site and may depend on which plant they are operating in. 3. What types of parameters or conditions are monitored by the plant operators while the wastewater is being processed? c. Operating and maintaining of the plant is covered in many NPDES permit requirements and limitations. Overseeing a pretreatment program to prevent industrial discharges interference or pass through, sludge contamination, or the plant to violate its permits. Sampling and analyzing wastewater and sludge prior to discharge or disposal to meet NPDES monitoring requirements. 4. Where does the plant’s treatment sludge (bio solids) go? Who monitors the management of sludge...

...Research 5.1 Positive Impacts of Human Activities on the Environment SC4730 Environmental Science Captive Breeding and Release of Endangered Animals Nearly extinct animals are bred in protected environs. When the numbers are sufficient, they are reintroduced in to the wild. One example is the Arabian Oryx. “These animals were captive bred in the Phoenix, San Diego and Los Angeles zoos and later released in the Middle East”(Patterson). “California condors, Mauritius kestrels, and black-footed ferrets are some of the other species that have been captive bred and released.”(Rogers) Selective Removal Invasive Species Some plants and animals deliberately or accidentally introduced into new areas often thrive there. They wind up replacing indigenous plants and the ecosystems that have been supported by them for thousands of years. “One example is Australian gum trees, which have become invasive in California. Efforts are being made to replace them with indigenous trees like the coast live oak.”(Patterson) Replacing Industrial Food Systems with Permaculture According to the Permaculture Institute, "Permaculture is an ecological design system for sustainability in all aspects of human endeavor. It teaches us how to build natural homes, grow our own food, restore diminished landscapes and ecosystems, catch rainwater, and build communities."(Rogers) More and more people are embracing aspects of permaculture, and both the environment and human health are benefiting.

...Markela Sharnae Hardy SC4730: Environmental Science Week 3: Analysis 1 7/21/2014 A keystone species is a species that has an unreasonably large effect on its environment relative to its large quantity. Man species play critical role in maintaining the structure of an ecological community, affecting many other organisms in an ecosystem and helping to determine the types and numbers of various other species in the community. There are different examples of keystone species which there could be predators, mutualists, and engineers. Since the prey numbers are low, the keystone predator numbers can be even lower and still be effective. Keystone mutualists are organisms that participate in mutually beneficial interactions, the loss of which would have a profound impact upon the ecosystem as a whole. Although the terms 'keystone' and 'engineer' are used interchangeably, which is better understood as a subcategory of keystone species. Out of all the keystone species in the world the one that I am most fascinated with is the jaguar. The jaguar is largely a solitary and opportunistic predator at the top of the food chain. It is a keystone species, playing an important role in stabilizing ecosystems and regulating the populations of the animals it hunts. The jaguar has been numbered as the near threatened in Central and South America. The jaguar acts as a keystone predator because of its widely varied diet, and they also help balance the mammalian jungle ecosystem with its...

...SC4730 Environmental Science Analysis 2 Nitrogen cycle Nitrogen exists in nature in many different forms, from molecular nitrogen in gaseous to the complex organic compounds in the body of plants, animals and humans. In an organism, Nitrogen exists in the form of organic compounds such as proteins, amino acids. When the microorganisms die, the amount of nitrogen exists in soil. Under the action of the group saprophytic microorganisms, proteins are degraded to amino acids. The amino acid to be a group of other microorganisms into NH3 or NH4+ called ammonium group of bacteria. This process called mineralization of organic matter such as through organic nitrogen is converted into nitrogen mineralization types. NH4 + form will be converted into the form of NO3- by nitrifying bacteria. (Wikipedia, Nitrogen cycle) Of the nitrate compounds are converted into nitrogen molecules, this process is called nitrification reaction was carried out by reaction of nitrate bacteria. N2 gas will be fixed in bacterial cells and plant cells are then transformed into organic forms of nitrogen by microorganisms group of fixed nitrogen. (Wikipedia, Nitrogen cycle) Thus nitrogen cycle is closed in most phases of the cycle metabolism and involvement of different groups of microorganisms. If the activities of a group are stopped the whole metabolism of the cycle will be seriously affected. The process of ammonium The organic forms of nitrogen converted to NH3 or NH4 +. a / The chemical urea ammonium:...

...SC4730/1125 ENVIRONMENTAL SCIENCE SHIVAJI PRASAD UNIT1 WATER CYCLE Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor. Studies have shown that the oceans, seas, lakes, and rivers provide nearly 90 percent of the moisture in the atmosphere via evaporation, with the remaining 10 percent being contributed by plant transpiration. A very small amount of water vapor enters the atmosphere through sublimation, the process by which water changes from a solid (ice or snow) to a gas, bypassing the liquid phase. This often happens in the Rocky Mountains as dry and warm Chinook winds blow in from the Pacific in late winter and early spring. When a Chinook takes effect local temperatures rise dramatically in a matter of hours. When the dry air hits the snow, it changes the snow directly into water vapor, bypassing the liquid phase. Sublimation is a common way for snow to disappear quickly in arid climates. (Source: Mount Washington Observatory) Why evaporation occurs Heat (energy) is necessary for evaporation to occur. Energy is used to break the bonds that hold water molecules together, which is why water easily evaporates at the boiling point (212° F, 100° C) but evaporates much more slowly at the freezing point. Net evaporation occurs when the rate of evaporation exceeds the rate of condensation. A state of saturation exists...

...Monarch Butterfly’s Reign By Mario Lopez ITT Technical Institute SC4730 Environmental Science Mr. Ramirez 1/15/2015 According to National Geographic monarch butterflies travel up to 3,000 miles each fall to their wintering site in central Mexico. In 2004, an estimated 550 million completed the winter migration, while in 2003 only 33 million arrived. Further, between 2012 and 2013, there was a 43.7 percent decrease in the area occupied by the butterflies in the winter sanctuaries, the decline has numerous reasons: climate change, deforestation, and habitat loss, agricultural use of pesticides and herbicides Monarch butterflies are known for the incredible mass migration that brings millions of them to California and Mexico each winter. North American monarchs are the only butterflies that make such a massive journey, the insects must begin this journey each fall ahead of cold weather, which will kill them if they tarry too long. Monarch butterflies reflect ecosystem health and biodiversity, they are pollinators which make them very important for plan reproduction, and ecosystem sustainability. During the journey north, monarchs produce four generations, and share habitat with small birds and animals which feed larger birds and animals. Monarch butterflies begin life as eggs and hatch as larvae that eat their eggshells and, subsequently, the milkweed plants on which they were placed, short after that the larvae become juicy, colorful caterpillars, then create a hard...
