Foster development of new drinking water technologies to address health risks posed by a broad array of contaminants. Use the authority of multiple statutes to help protect drinking water. Partner with states to share more complete data from monitoring at public water systems (PWS). “ http://water.epa.gov/lawsregs/rulesregs/sdwa/dwstrategy/upload/Drinking_Water_Strategyfs.pdf Distinguish between water quality criteria pollutants and maximum contaminant levels. There are several types of contaminants like: Microorganisms, Disinfectants, Disinfection Byproducts, Inorganic Chemicals, Organic Chemicals and Radionuclide’s.
Our geography fieldtrip involved looking at the features of a drainage basin. This was done by going to different areas around our local river. To conduct the fieldwork investigation, we first had to prepare to make sure we knew what we were doing in detail. First, we produced a hypothesis that we were going to test. Hypothesis: As valley gradient increases, velocity of the river also increases.
Compare and Contrast of Risk Hydroelectric Development verses an Irrigation Scheme Keller Graduate School of Management PM595 Project Risk Management Professor Rich Hiles PM595 - Project Risk Management SEP11 Sec A 2011 Contents Identifying Risk ............................................................................................................................................................. 3 Quantifying Risk ........................................................................................................................................................... 4 Risk Assessment ............................................................................................................................................................ 4 Differences and Similarities .......................................................................................................................................... 5 References ..................................................................................................................................................................... 6 2|Page Identifying Risk Quantitative risk analysis defined by the PMBOK as “the process of numerically analyzing the effect of identified risks on overall project objectives” (PMBOK, 2008). The first project involves hydroelectricity, while the second project involves an Irrigation System that will be built in two separate stages. Risk is involved with every project along with a great deal of uncertainty. It is the job of the Project Manager (PM) to determine and understand the uncertainties surrounding a project and how much risk they are willing to take on with each new project as well as how the PM will analyze and mitigate certain risk factors. This paper will compare and contrast two case studies that involve a hydroelectric development project and an
This illustrates the affects of water velocity on movement and deposition of sediment. In addition, water velocity has been directly correlated to the distribution of organisms throughout a running body of water (Davis, 1989). In a shallow stream located in France, an abundance of both sediment and aquatic life was observed in the pool areas of the streams (Mermillod-Blondin, 2000). Marine biologists often use the mean velocity of water flow to compare the flow of nutrients and sediments. This same method can be used in our study.
Write a 1500 word report that addresses the following: For an endangered species/closely related group of species of your choice describe the National, European and International legislation available to conserve it/them. YOU MUST USE A DIFFERENT SPECIES TO THE ONE USED IN YOUR PRESENTATION. You should also provide some background context for the species and consideration of the future survival of your selected species. Your report should include relevant maps, diagrams and/or figures CONSERVATION LEGISLATION FOR ENDANGERED MUSTELIDS Mustela lutreola, European mink Species background, ecology, range, why endangered: The European mink, (mustela lutreola), is listed as endangered by the IUCN red list and the population trend is declining. Though the species is threatened, estimates put the current population decline in the last 15 years at a minimum of 50%.
Water is a powerful source. It causes erosion or more specifically runoff. The source of a river may come from a mountain. When it rains on the mountains it may create a stream, then later into a river. It turns into a river because of all the water the mountains have and then creates a path.
Wetlands especially lakes and ponds perform many vital functions which includes treatment of waste water (Kadlec, 1978), downstream flood control (Novitzki, 1979), recharge of ground water (Carter et al., 1979) retention of sediments and nutrients (Dean, 1979) and regulation of water quality (Larson, 1982), irrigation, energy production, recreation, tourism and provide habitat to wild life. They are one of the most productive ecosystems and constitute rich natural resources. In Assam, comprising both Brahmaputra and Barak Valleys, there are innumerable fresh water lakes, ox-bow lake (Anua), marshy tracts and seasonally flooded plains and hundreds of revering sand-bars, islands, temporary pools, beels and other small aquatic
The analogy of a river to describe illness was developed by McKinlay (Earle, 2007. P52). These factors are considered to be downstream on the river and are a consequence of the effect of the factors upstream, which he argued that doctors should focus upstream where the problems, and solutions, lie. The upstream factors of housing, living and working conditions and access to healthcare are the focus of the next layer while the outer layer suggests broader socio economic, cultural and environmental issues. These factors are beyond the influence of the individual; however, any change in these factors will have a direct influence on communities and individuals.
This act was established to protect all aspects of the nation’s bodies of water (PBS, 2002). Before this law was passed, pollution was dumped directly into lakes, rivers, streams, and even the ocean, making it unsafe to swim in these bodies of water (PBS, 2002). The pollution also disrupted the biological aspects of these bodies of water as well (PBS, 2002). Once it became apparent that this was becoming a safety hazard the nation’s leaders stepped in to do something about it. In 1969 the bacteria in the Hudson River was 170 times the safe limit (PBS, 2002).
In 1992, the WWF commenced work in the Danube region, with its main concern being the protection and conservation of the Danube River. They expanded the operation in 1994 and once again in 2000, to include the European Union (EU) Water Framework Directive. In 2000, the fund secured agreements with the heads of state of Bulgaria, Romania, Moldova and Ukraine, to restore 2,236 km2 of floodplain to form a 9,000 km2 “Lower Danube Green Corridor.” This corridor has reduced the effects of floods by approximately 40%, restored biodiversity, improved water quality, and has since enhanced the living conditions of local communities
