Groundwater contamination is nearly always the result of human activity. In areas where population density is high and human use of the land is intensive,groundwater is especiallyvulnerable. Where chemicals or wastes may be released to the environment, either intentionally or accidentally has the potential to pollute ground water. When groundwater becomes contaminated, it is difficult and expensive to cleanup. Ground water can be contaminated by human activities and also natural causes when the effluent from the industries, residential areas and commercial purpose are stored the contaminants can reach the groundwater through activities like spills, discharge or landfills and leakage of the underground storage such as septic tanks. Some substances
Water is a major resource human’s need for survival. As an important part of Earth’s water, groundwater is an indispensable resource for the development of the global social economy and people’s lives (He-rong, et. al., 2015). Groundwater is an easy way for humans to be exposed to heavy metals. Heavy metal contamination is a significant problem in several community and agricultural areas (Chotpantart, et. al., 2013). Agrochemicals, including plant nutrients and fertilizer, can cause increases in the concentration of heavy metals in the water and soil, and these heavy metal can potentially reach levels in the ground than in the surface and eventually groundwater (Chotpantart, et. al., 2013).
Since I live in the Texoma area the majority of our drinking water comes from Lake Texoma. I think the three sources of groundwater contamination that might affect groundwater in my area would be human-made materials that are littered into the lake, agricultural activities, and human/animal wastes. There are a lot of people in the area who like to go fishing near the lake and drinking alcoholic beverages. These people throw their beer cans and all of their trash into the lake. They also urinate and defecate into the lake as well. There are many nearby farms and ranches to the lake and with all of the flooding water has run-off from these areas back into the lake.
We hope our project does not encounter any delay. If it is the case, we will have to create a plan to solve that matter. We want to be ready for the upcoming Medical States University September class 2015, to integrate fully simulation education in the curriculum.
The simulation is a model with no right or wrong answers, and has rational expectations of both the person using the simulation and the person reading the analysis of the data from the analysis. This is in the category of macroeconomics because it deals with the “big picture” of the analysis’ expectations.
From my point of view, our world needs to use the groundwater for something useful for citizens in the world. However, a very beneficial way to use the groundwater would be allowing the citizens to pull up as much groundwater they desire to cook food, and for their hygiene. Without the proper hygiene, such as brushing your teeth, or showering can result in horrible health issues.
Groundwater pollution is a major problem that is growing in all over the world. Of course the united states America also facing this problem. People of Mississippi State are worried about groundwater pollution due to the several human activities. Groundwater is a main source of their water supply. Disposal of solid waste in landfills is an economic option for many municipalities in developing countries where alternatives like incineration and composting are costly. However, groundwater pollution from the leachate generated within the landfill and migrating through the bottom liner material into the underlying groundwater aquifers remains a major public health concern I studied chemical parameters of groundwater in Alcorn State University as a part of my project.
A surge in the global population in the past century has brought about an immense strain on the commons. It is estimated that 35% of the global population suffers from “severe water stress” (Wada et al., 2010). Only 3% of the world’s supply of water is freshwater, with 68.7% being locked away in the glaciers, 30.1% in ground water, and 0.9% in surface water bodies (Shiklomanov, 1993). This makes groundwater the most abundant fresh water source readily available for human consumption. Estimates for global groundwater withdrawal are between 750 and 800 cubic kilometers per year (Konikow et al., 2005). Severe land subsidence and depletion of the groundwater table is occurring in both developing and developed nations. This has made
Groundwater is water which is located beneath the surface in soil pore spaces and in permeable geological formations. Groundwater is a very important source of freshwater it makes up a large percent of the world’s accessible freshwater resources. Including, billions of urban and rural people depend on groundwater for their everyday needs. We depend on it for our own safety and the safely of certain groups which include the children, the elderly, and the poor who are more vulnerable to diseases. Waterborne illness is a public health issue in North American and around the world. In an article called Estimating Waterborne Disease Risks in the United States it states that, “That significant data and method-based uncertainties remain in the improved
Safeguarding groundwater is the main concern in Western Australia as groundwater provides 70% of Perth 's fresh water requirement(Appleyard et al., 2004)and it is used for domestic, agricultural, industrial and municipal purposes. Perth, the capital city of Western Australia is a rapidly developing and expanding city which is located over a shallow aquifer (Appleyard, 1993). Currently, Perth is encountering substantial water scarcity as a result of increasing population (i.e. 2.3% population growth rate) and effects of climate change and escalating groundwater demand. Therefore, the need for Perth’s groundwater system to be monitored and protected is of greater importance(Sarukkalige, 2011). Acording to recent investigations, elevated quantities of disseminated pollutants, as well as a remarkable number of restricted contamination plumes, were
“The defining attributes of a concept are the characteristics shared with other instances of its use in the literature” (Failla, 2014, p. 576). Simulation occurs when there is experimental learning in a safe environment. Simulations should be accessible to all learners, have a team leader, where roles are clearly defined, closed-loop communication is established and maintained, the sole purpose for gaining educational knowledge, and a post performance evaluation tool utilized not only to identify areas needing improvement, but to praise good teamwork, performance and skill set. Closed-loop communication is essential, as team members confirm the team leader is being heard, tasks are communicated effectively and correctly, and team members confirm
Simulation is a computer process that gives a probable NPV or IRR for a project. All factors that affect the project’s returns are input. The computer then randomly selects one observation from each category. All of the observations are combined and the NPV or IRR is calculated from those figures. Simulation gives a range of outcomes as well as the probability of the outcomes. It provides the total risk level of a project.
The air we breathe, the water we drink, the ground where we grow our food, is polluted with harmful things. Pollution is the introduction of harmful or poisonous effects of a substance into the environment. It disrupts the balance of people’s lifestyle when they are contaminate. Pollution balance in the environment and ecosystem. The environment is in the process of becoming unsafe or unsuitable to use. Pollution can come in many different form, such as air, water, soil can have pollutant that can wreak havoc on the environment. Pollution can be a form of anything and cause so much harm. It can take the form of chemical substances or energy. When chemicals are released by spill or underground leakage, the soil can become contaminated, which is soil pollution. The release of chemicals and particulates into the atmosphere, is the product of air pollution. The industrial wastes dumped into the rivers and other cause an imbalance in the water leading to its severe contamination and death of aquatic species.
Interactions between groundwater and surface water are complex. Consequently, groundwater pollution, sometimes referred to as groundwater contamination, is not as easily classified as surface water pollution. By its very nature, groundwater aquifers are susceptible to contamination from sources that may not directly affect surface water bodies, and the distinction of point vs. non-point source may be irrelevant. A spill or ongoing releases of chemical or radionuclide contaminants into soil (located away from a surface water body) may not create point source or non-point source pollution, but can contaminate the aquifer below, defined as a toxin plume. The movement of the plume, a plume front, can be part of a Hydrological transport model or Groundwater model. Analysis of groundwater contamination may focus on the soil characteristics and site geology, hydrogeology, hydrology, and the nature of the contaminants.
Environmental pollution is a major problem in the world, posing many health risks to both humans and the environment when exposed to the pollutants for long periods of time. Environmental pollution can simply be defined as “the presence in the environment of an agent which is potentially damaging to either the environment or human health (Briggs, 2003, 2).” There are many different types of pollution, such as air pollution, water pollution, and soil pollution. Environmental pollution needs to start subsiding before it becomes an even more serious problem.
