Groundwater

The article, “Is contaminated groundwater an important cause of viral gastroenteritis in the United States?”, by Floyd Frost, Twila Kunde, and Gunther Craun, published in the Journal of Environmental Health, October 2002, describes how due to the contamination of groundwater, from sources such as runoff and sewage treatment plant effluents, many studies have been conducted regarding human health risks from potential viruses in groundwater. Waterborne outbreaks often occur, and are probably…

The Fruit Avenue Plume (FAP) Superfund site (Site) is identified on the National Priorities List (NPL) as a chlorinated solvent groundwater plume, located in the downtown area of Albuquerque, New Mexico (Figure 1). The site originally consisted of a groundwater-contaminant plume, spanning multiple aquifer zones up to 544 feet deep; it was approximately 3,500 feet long and ranged in width from 550 to 1,300 feet. The U.S. Environmental Protection Agency (EPA) issued a record of decision (ROD) in…

Water resource depletion: Resource depletion means the lack of that particular resource that is consumed faster than it is replenished. Thus, water resource depletion can be described as lack of water due to its excessive use or it can be said that water resource depletion occurs when water is wasted and over used. As water is most essential for all life forms, deficiency can be resulted into many issues regarding health and social life of people.…

water levels” (WICCI), due to climate change. Wisconsin will also have warmer winters leading to increase winter precipitation causing river flooding of lakes, rivers and groundwater. Managing water resources in Wisconsin is critical to adapt to the impacts of climate change. Climate change will produce more rainfall and groundwater…

phase liquids, also known as DNAPLs are chemicals denser than water, which do not typically dissolve into water. These toxic chemicals seep through the soil and find ways into groundwater depending on the physical chemistry of the substance(s). When the dense non-aqueous phase liquids (DNAPLs) have entered the groundwater they will continue to flow with it as a result of the hydrological cycle. There is no absolute way of knowing where the source of the DNAPLs is located, or if any bodies of…

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…

This transition could potentially increase the life expectancy because their groundwater is potable. According to Jon Hamilton’s article, “the country has dug deep wells that reach the aquifers because they are protected from the surface pollution” (Hamilton). This shows that El Salvador has taken into account the amount of Salvadorians…

sulfate (nH2O) (Carlo Erba), hydrogen peroxide (H2O2) (Carlo Erba), acetonitrile (Sigma-Aldrich) and Milli-Q water were used to perform all the experiments . All the reagents were used without further purification. Natural groundwater samples Samples were taken from groundwater wells localized in a small rural community (coordinates: 3º21’03.38” N, 76º26’24.51”) near to the municipality of Candelaria (southwest of Colombia). The sample was stored at -4 ºC in plastic bottles and then it was…

Increased groundwater use is reflected in declining groundwater levels; in groundwater basins not experiencing overdraft, a pattern of water level drawdown during dry conditions and recovery during wet conditions is typically seen. groundwater level decline in overdrafted basins is typically exacerbated by drought.( Drought and Groundwater). It is great to see that California’s weather finally decided to help with the dryness from drought; the increase of rain and surprisingly incline of snow…

California Groundwater California has been in a really bad drought. Wells in East Porterville, Los Angeles have gone dry. At least 1,300 people have lost their water. If people keep taking to much groundwater all of the water will be gone and then nobody will have water to use. That's why there should be regulations on groundwater. If there are no regulations on groundwater then people are still going to go overboard and take more than they should.…
