Groundwater

Results: In Tully Valley, the mudboils are where pressurized groundwater flows up through a restricting layer of silt, clay and fine sand. Mudboils usually take place in subduction zones of the Earth. The mudboil causes the land surface to slowly decline and the erosion of suspended sediment which creates a sequence of concentric ring fractures around the discharging mudboil. Mudboils are driven by pressurized groundwater, geothermic heat, and gases. As a consequence, the mudboils…

of Vashon Groundwater Modeling Report Date: June 7, 2016 Introduction This analysis is being written in order to evaluate the “Vashon-Maury Island Hydrologic Modeling: Technical Report” and determine whether or not the results of the report are adequate enough to be used for future regional groundwater planning (“ESS 454,” n.d.). I will make this determination by taking note of how well the technical report provides answers to the “needs” that a proper technical report for a groundwater system…

exposed to the atmosphere is originated from it’s natural source which is the earth itself. Inorganic arsenic is found in groundwater in several parts of the world. Arsenic levels in natural water are usually low, however in these several parts of our world, which includes, Argentina, Bangladesh, Chile, China, India, Mexico, and the United states, arsenic contact with groundwater is significant. Humans are exposed to high level of arsenic contaminated water through drinking water, consuming food…

California is the one of the major states where businesses, agriculture, and tourism are booming. The government has been intervening to attempt to conserve water, but the current policies are not enough to ensure the safety of the economy. Relying on groundwater will also not be an option very soon since deep aquifers are not rechargeable. We need to start viewing the California Drought much more seriously and contribute in any way we can in order to fully defeat this natural…

Hydrologic cycle refers to the movement and storage of water between the land, oceans and atmosphere (Kuchment 2004). It involves several main processes, which include evaporation of water from the oceans, condensation of the atmospheric moisture to form clouds, precipitation, transpiration and so on (Hubbart 2011). There are mainly three types of human activities that affect the hydrological cycle, namely surface water regulation related to lakes and rivers, water release and abstraction, and…

Monterey County has many aquifers to provide fresh, clean water, 80% of this is groundwater (Public Services, 2010). More groundwater pumping leads to localized over-drafting which in turn causes saltwater intrusion into any of its six water basins: Parajo Valley, Prunedale, Salinas Valley, Marina Fort Ord, Carmel, or El Toro (Public Services, 2010). Arguably the most important basin is the Salinas Valley because it is home to the Salinas River which not only supplies water for the surrounding…

While tap water is available to many people, it is superior to bottled water in many ways. Some bottled water companies get their water from sparkling springs, but more than 25% of it comes from a municipal source (Jemmat). Price is another factor, compared to the price of gas today it costs more for a liter of bottled water than the same amount of gas. Tap water also creates a much more dependable source of water. With the use of tap water also takes away from the 81.7% of plastic bottles found…

most direct and most severe impact is the lack of improved sanitation, and related to it is the lack of safe drinking water” (Schwarzenbach, R et.al, 2010). SCALE. Water pollution can occur in many sources of water especially in rivers, lakes, groundwater and oceans. Communities and villages drink and use these contaminated and polluted waters, as they may have no other option. Many villages do not have any way of gathering clean water, for example wells. Clean water is a huge aspect of…

Fracking has been a controversial topic for many years now and continues to be questioned. There are debates about the definition of fracking and whether the term refers to the entire industrial process or just the underground water blast that fractures the rock after the drilling is finished. One of the concerns about fracking are the flow back water containing a cocktail of chemicals used for many beneficial purposes but often contains radioactive materials and salts from the underground…

Salt solution near Onondaga Lake formed as a result of the dissolution of halite from the Tully Valley. The salty groundwater naturally flowed from the high elevation at the southern end to the low elevation at the northern end. According to Kappel, the artesian pressure in Tully Valley is exacerbated by dissolution of a halite bed below confining beds of shale, till and…
