Arsenic contamination of groundwater

sometimes fail to realize the how far agricultural ideology has come in the last 50 years. Rachel Carson highlights throughout her 1962 book “Silent Spring”. Although it may have not been intentional, Carson’s book sparked a revolution in the world that still continues to improve the way things are produced, disposed, and regulated throughout the United States. Rachel Carson enlightens us of how harmful these industrial chemicals are to not only human health but also the health of the environment. Entire ecosystem contaminations of topsoil’s and ground water are evident another problem comes in sleuth of the first. Pest’s resilience to the toxic chemicals and amounts of DDT along with nonchalant government officials and crooked factories are to blame for contribution for the evolution of ecosystem resilience as well as the Arsenic contamination in out groundwater. Rachel Carson's excellent piece of work gave a voice to people’s who’s lives where most affected by the contamination of their ecosystem as humans. Throughout the first paragraph of the chapter titled Elixirs of Death, Rachel Carson fills us in on the development and discovery of DDT for agricultural use as pesticide as a result of chemical testing for warfare testing purposes. At the time of its discovery DDT was presumed safe to apply for an array of uses. At the end of that very same paragraph we learn in 1947 synthetic pesticide use in the United States soared from 124,259,000 pounds to 637,666,000 pounds in…

We focused on arsenic exposure health risk analysis through oral ingestion and dermal absorption pathways of groundwater in the present study. The local residents in the study area were interviewed for basic information such as age, sex, body weight, health status, socio-economic status, food habits and drinking water sources. It was mentioned that the residents were using mainly groundwater for drinking and other purposes. The poverty, lack of awareness and having no effective alternatives were…

Arsenic contamination and possible remediation Victoria Reyes Texas A&M International University Abstract Arsenic can be found in many places on Earth. This includes from natural sources and as a by-product from different anthropogenic activities. The fact that arsenic can be found so commonly on Earth has lead to the contamination of several countries’ drinking water. This has put many people at risk for arsenic poisoning. There are many complications that come from the continuous ingestion…

The hydrological cycle is the natural cycle in which water evaporates from the ocean and other bodies of water, accumulates as water vapor in clouds, and returns to the ocean and other bodies of water as precipitation (AWWA, 2009). Water that is not recharged by the hydrological cycle, such as groundwater, or sources that require a significant amount of time to recharge is characterized as non-renewable water (AWWA, 2009). Therefore, substantial withdrawal of non-renewable water can ultimately…

naturally. It can be dangerous when released from rocks, volcanoes and forest fires. It is then released naturally throughout the atmosphere. However, airborne mercury contamination results mainly from human activities. The main activities include: Burning of coal, oil, wood that contain mercury, if not burning mercury itself. Many power plants and companies do so and make up for most of the toxic activity. According to the EDF(Environmental Defense Fund) “A large amount of toxic mercury…

Fracking is the process of drilling deep into the earth’s crust and injecting water, sand and chemicals under immense pressure in order to obtain natural gas. With this process there are benefits and also disadvantages. There are many risks to groundwater from surface spills that are associated with shale energy development, they can be managed or mitigated by following certain precautions and steps. Groundwater is present throughout the atmosphere. There is surface water, atmospheric water and…

Analysis: Public Health Implications Arsenic in drinking water is a world wide environmental public health threat. Anyone who drinks water contaminated with high amounts of arsenic can be effected by it, but developing countries are the ones who seem to suffer the most from arsenic poisoning. The united states and the World Health Organization (WHO) applied a strict standard for arsenic in drinking water to be at or below 0.01 mg/1 or 10 parts per billion, but unfortunately not all countries…

in your essay. Your name Professor 23 April 2016 Water is a vital element in the life of every human being. Not only is it essential to our health, but also for use in numerous household tasks. Everyday water is used for cooking, bathing, cleaning, and drinking. It is therefore necessary to consider the safety of the source of the water we use daily. Where does our water come from? How is it treated? How do we know it is safe to drink? In USA there are two main sources of water: surface…

often saw as transient and undesirable. The discriminatory expansion of cities left unincorporated communities under-resourced, and as a result, their infrastructure suffered, including infrastructure that would have provided access to potable water, leaving them ill-suited to combat both drought and pollution from various industries. Due to discrimination and exclusionary housing practices, unincorporated communities grew around agricultural land or industrial areas. Additionally, industries…

understand what Arsenic is and why this element is in our drinking water. To begin with our introduction to Arsenic, we should all understand that it is a semi-metal element from the periodic table that we are mostly familiar with. It is odorless and has no type of specific taste to the human tongue. It is mostly sourced from natural deposits in the Earth, however, it’s also known to be sourced from agricultural and industrial practices all over the world. It is simply found in nature and in…
