Charles F. Richter, Father Term Paper

… Since tremors range in magnitude, Richter recorded information based upon a logarithmic scale that was calibrated to the tremors produced in Southern California (Park). While modern seismographic machines record data electronically, the first seismic activities recorded utilized a pen attached to a string hung above a cylindrical drum. Seismic activity was then calculated by measuring the pen's swing in millimeters, taking its logarithm, and applying a correction for the distance between station and earthquake (Park).

With help from Gutenberg, Richter was able to extend his scaling logarithm to include seismic activity worldwide. The findings conducted by the utilization of the Richter Magnitude Scale were published in 1935 and quickly became the standard measurement for seismic activity ("Richter, Charles F. (1900-1985)"). Along with Gutenberg, Richter published Seismicity of the Earth and helped to locate epicenters around the world and classify them according to geographical region. Richter spent most of his career at Cal Tech, except for a year where he lectured at the University of Tokyo as a Fulbright scholar. Additionally, he advised government officials in Los Angeles about the imminent dangers posed by hazardous architectural ornaments; Los Angeles officials heeded his advice that would later prove to be beneficial when a major earthquake hit the city ("Richter, Charles F. (1900-1985)"). In 1958, Richter published Elementary Seismology; the textbook was based upon his lecture notes and years of data and research ("Richter, Charles F. (1900-1985)").

Richter spent his entire life studying seismic activity. His contributions to the field have helped people around the world understand how earthquakes occur and the consequences thereof. Furthermore, Richter's contributions to the field of seismology have helped in the development and construction of safer buildings in earthquake-prone areas.

Ucsd Application as a Resident Essay

… There is still much more to be done, however. I would very much like to attend the summer program "Earthquakes in Action" at the University of California at San Diego's Jacobs School of Engineering. I hope to learn more about earthquakes and explore various academic and career options in which they are a focus.

I have a strong background in mathematics and I believe that prepares me for the rigors of the summer course. I am particularly interested in the ways that bridges and buildings respond to earthquakes and I look forward to the opportunity to use computer-generated models to study the methods of design and construction that are meant to address these problems. I would appreciate the opportunity to study with experts in seismology and structural engineering and learn as much as I can. The summer program sounds like a great cooperative learning experience. I am really looking forward to the possibility of working with professionals and other students in… [read more]

Comparison of the 2011 Japan Earthquake and Tsunami With the 1960 Chilean Essay

… ¶ … Chilean earthquake of 1960 and the recent Japanese earthquake, the Valdivia quake that ruptured the Chilean coastline more than five decades ago is considered by many to be the most powerful earthquake in modern times. It was the largest seismic rupture ever recorded, achieving a 9.5 rating on the Richter scale. The resulting tsunami affected nearly the entire Pacific rim, causing substantial damage across Chile, Hawaii, Japan, New Zealand and Australia. The primary tsunami wave sped to Hawaii, where it devastated the town of Hilo. Waves higher than 30 feet were recorded in the Philippines and Japan in mere hours following the initial shock.

Most accounts placed the death toll at roughly 6,000, while economic losses related to the quake range from U.S.$500 to U.S.$600 million (Seismo-Watch, 2011). Nearly 40 per cent of the town of Valdivia was wiped out, leaving more than 20,000 citizens homeless. Entire cities were flooded, new wetlands were created, and electrical and water facilities were crippled in the quake's aftermath. Local rivers and pipelines were stifled with debris that included entire houses and portions of neighborhoods (Extreme Science, 2011). However, the death toll remained below that of many quakes (including the Japanese quake of 2011). This is likely due to the sparse population in the surrounding region and the propensity of civil engineers to developing municipal centers on higher elevations. Additionally, most towns consisted of wooden structures, as opposed to more deadly brick-and-mortar edifices that could potential pose more threat to life when thrown about by tidal waves.

Like the Japanese quake, the Valdivia rupture was a megathrust quake. It occurred far below the earth's surface and was caused by the subduction of one tectonic plate beneath another. Subduction quakes tend to cause the largest seismic activity due to their capacity to release more built-up stress in one powerful fissure. Among the catastrophic results were a flood that nearly destroyed the entire San Pedro River Valley and a massive volcanic eruption at Cordon Caulle (Extreme Science, 2011).

The Tohoko quake that recently occurred in Japan was slightly less powerful but caused significantly more damage, mostly due to the high concentration of population and the powerful tsunami waves that rushed ashore in the subsequent hours. The magnitude of the Tohoko quake was 8.9, among the largest ever to hit the Pacific Rim. It occurred at a depth of roughly 20 miles beneath the ocean's surface. The destructive tsunami waves that resulted measured nearly 100 feet high and destroyed several towns in spite of the warnings and evacuation measures issued by local governments. While the death toll is still being tallied, current numbers confirm more than 11,300 deaths, with 16,290 people still reported missing. In… [read more]

Glaciers Come in All Shapes and Sizes Essay

… Glaciers come in all shapes and sizes, offering the viewer to describe the form in ones opinion. Each observer may describe the same glacier in a plethora of ways. The valleys and streams, curves and bends are ever changing. The supporting points in the article written by Ehrlich (2004) contain facts as well as opinions that support the idea of one's own perception and the factual characteristics of the Perito Moreno Glacier.

The facts stated in the article include information that about the size of Perito being 257 square kilometers across. In the center there is a two meter advance daily. There are warm and cold glaciers this depends on the altitude and latitude. Cold glaciers do not slide as easily, these glaciers are affixed to rocks. Warm glaciers have internal melt-streams at every level and torrents of water flow out from under the ice at the glaciers foot.

Further into the article Ehrlich (2004) describes the glacier in a personal manner. She compares it to the human body describing cheek bones, teeth etc. In conjunction with the descriptions of the forms that can be taken by the glacier she also explains the fluctuations in mass and form that take place every day. Throughout the writing comparisons are made to everyday encounters of the average man or woman. She expresses that the glacier balances its gains and losses like a banker. A glacier can give away more than it takes in. A glacier is an archivist and historian. It registers every fluctuation in weather. It saves everything no matter how small or big, including pollen, dust, heavy metals, bugs, and minerals. As snow becomes firm and then ice, oxygen bubbles are trapped in the glacier, providing samples of ancient atmosphere: carbon dioxide and methane. Records of temperatures and levels of atmospheric gases from before industrialization can be compared with those after a mere 150 years. A glacier is time incarnate.

The article gives clarity not only into the difference that… [read more]

Hydrological Hazard Essay

… ¶ … forest conversion to pasture affecting the hydrological response of Amazon catchments? Signals in the Ji-Parana basin" by Rodriguez, Tomasella, and Linchares published on the 26th January 2010 in Wiley Interscience. It goes ahead to discuss in depth runoff. It is apparent to majority of us that the land use and vegetation cover over the land does not remain constant but constantly changes typically because of human activities and deforestation respectively. Deforestation on its own has the potential of affecting not only the forest/vegetation cover, but also hydrological response (Rodriguez, "is forest conversion to pasture affecting hydrological response"). Despite that many of vegetation changes are detectable in majority of small-catchment researches; it can however be difficult in large-scale studies. For this reason, at Ji-Parana basin in southwest Amazon, land use, land-cover changes, and stream flow fluctuations are examined combined with remotely sensed deforestation information to obtain viable results. Despite the Ji-Parana basin being large (<30,000 km2), it has been greatly affected by human activities modifying the land cover. From the statistical analysis, where daily stream flows were correlated with land cover data on smaller areas (sub-basins), the results indicated that the effect of land use and land cover changes on the response of hydrological process in large scales is time lagged (Rodriguez, "is forest conversion to pasture affecting hydrological response"), that is flow patterns are significantly affected by land cover and topography of the location resulting to high peak flows in streams hence storm flows. From the study, it proved easy to detect signals of the impact of land use and land cover changes on hydrological processes on smaller basins compared to large-scale considerations. This revelation thus challenges the existing mathematical models that are designed for faster hydrological response (Rodriguez, "is forest conversion to pasture affecting hydrological response"). Land activities and vegetation cover affects the speed and duration surface water from rainfall/storms takes before reaching streams significantly affecting stream flow hence flooding potential.

Rain falling on land has the potential of flowing either rapidly or slowly depending on the land cover as runoff and finally to streams. In addition depending on the soil characteristics of the area under consideration, infiltration varies where some of the water can percolate through the soil to greater depths… [read more]

Geosynclines and Accretionary Prisms Term Paper

… Geosynclines v. Accretionary Prisms

Structure and formation of geosynclines

Geosynclines such as the Neoproterozoic Wonoka canyons now located on the southern portions of the Australian continental land mass form as sediments deposit in submarine basins, eventually leading to the compressions and fracture of these deposits and the emergence of canyons or linear troughs -- the geosyncline proper (Giddings et al., 2010). The formation process of these submarine geological features is largely dependent on the destruction of continental crust, especially along its margins, as it is broken down into the sediment that then collects in the submarine basins to form geosynclines, which can either be subjected to further oceanization, moving away from the continental crust, or drawn up out of its submarine birthplace as in the Neoproterozoic Wonoka canyons system (Giddings et al., 2010; Marakushev & Marakushev, 2008). This has led to some measure of debate regarding the origins of certain specific geographic features.

The Neoproterozoic Wonoka canyons, for instance, were hypothesized to be of non-marine origin due to a lack of defining marine features such as wave patterns and an abundance of crustal material (Giddings et al., 2010). The material is now, however, hypothesized to have collected as sediment from runoff and erosions of the continental crust, and the lack of wave patterns and other shallow-water formations is believed to be due to the deep-water nature of the Neoproterozoic Wonoka canyon's origins (Giddings et al., 2010). The depth of the canyons and the degree of fracture is indicative of the scale and mechanisms of a geosyncline's formation.

These mechanisms can also be determined at least in part by the specific substances found in certain geosynclines. South Australia again provides an excellent real-world example; the types of material found in the Wokona Formations and in neighboring canyons are definitely of continental curst origin, yet there exists no explanation for this material's appearance in these formations other than a transference from some other crust via erosion and oceanic currents (Von der Borch 1985). The specific carbonate sediments that comprise layers of the rock in these formations, that is, did not originate on the continental crust where they are now found, but rather from some other area that was eroded away during the Proterozoic era. The sediment that resulted from this erosion was deposited in a submarine basin and eventually coalesced through compression, faulted, and fractured into the formations seen today (Von der Borsch 1985).

As diagram one in the Appendix clearly shows, plate movement from divergence occurring in oceanic plates puts lateral pressure on the basins where geosynclines form, resulting in a pattern of sediment build up… [read more]

Newsrx Science. "Earthquakes Actually Aftershocks of 19th Thesis

… ¶ … NewsRx Science. "Earthquakes actually aftershocks of 19th century quakes."

According to a collaborative study recently conducted at Northwestern University and the University of Missouri-Columbia, small earthquakes that occur in the Central region of North America are actually not contemporary earthquakes; they are actually aftershocks of much stronger earthquakes that occurred nearly two centuries ago. In principle, that is a result of the different rates of relative tectonic motion between the respective tectonic plates involved in active fault lines after large earthquakes of magnitude 7 and above.

Whereas fault lines closer to the coastal periphery (such as the San Andreas Fault in California) continue moving past one another at a rate of approximately an inch and a half per year after a major earthquake, those located closer to the central mass of tectonic plates (such as the New Madrid Faults) move 100 times slower. As a result, the aftershocks of earthquakes involving peripheral fault lines tend to subside after approximately one decade while those caused by large central plate faults can continue for centuries.

In principle, the researchers compared recorded patterns of large recent earthquakes to the known patterns associated with the gradual decrease in the magnitude of successive aftershocks. The results confirmed that the small earthquakes recorded in this decade are indeed part of the series of aftershocks from much earlier large earthquakes such as the 7.2 magnitude Hebgen Lake earthquake in Montana, Idaho, and Wyoming a half century ago.

Scientific Concepts

After large tectonic shifts that cause significant earthquakes, the tectonic plates involved continue their relative motion with respect to one another for many years afterwards. This is a function of the tectonic settling that scientists refer to as "swamping" their changes in position. In effect, the… [read more]

Soufriere Hills Volcano Eruption Thesis

… ¶ …

Recently the Soufriere Hills Volcano began erupting ash, magma, and hot gasses on the island of Montserrat in the Caribbean. The ash plume is estimated to extend nearly 40,000 feet into the Earth's atmosphere. The volcano had not erupted since 1995, but shifts in the local tectonics have given rise to some serious instability in the region's volcanoes. Many flights and travel plans had to be rescheduled due to the volcanic activity. The area around the volcano has been an exclusion zone since 1995, where people were discouraged from visiting unless they were part of a guided tour or scientific expedition. The volcano's exclusion zone is similar to the one constructed around the vicinity of Pompeii in Italy, and the 1995 eruption was compared to the Italian eruption 200 years ago in that it buried an entire city and killed many people with its pyroclastic flows and associated tremors. The former capital of the island nation, Plymouth, was nearly completely buried by the 1995 eruption, and most of the population fled following the 1995 eruption. The Soufriere Hills Volcano had been dormant throughout recorded history until the 1995 eruption and now has been awakened once again. Since the islands surrounding the volcano are a popular tourist destination, the local economy will likely be impacted just as much as the local travel industry has been.

The Soufriere Hills Volcano is part of a larger group of stratovolcanoes, which are made up of many layers of ash, lava, and mud flows. These volcanoes are subject to earthquake… [read more]

Kant's Transcendental Aesthetic Essay

… Kant's Transcendental Aesthetic

The Transcendental Aesthetic is the manner by which we attain our sense-originated knowledge of the physical world. Knowledge is attained through the immediacy of our relation to objects and it is through that relationship that all our thoughts are directed thus our understanding of our world is shaped by our capacity for relating to the objects in the world around us. In essence, my understanding of a rock is built upon the depth of my capacity to experience the rock in any manner (physical, emotional, intellectual, etc.) that I have the capability of reaching. Thus, as I experience the rock through an immediate relationship to it and the context in which I encounter the rock, my understanding, my total definition of that which is "rock" also shapes how I understand, categorize, experience, relate to and function within the context of other objects just as the same is true in reverse for the rock. Our ability to function within the world is entirely dependent upon our understanding of the world. That understanding is wholly dependent upon our ability to perceive the world through depth of our relationships with the objects within it. These relationships are built both in space and in time and the appearance of an object, our "sense" of it, is thus shaped both by context in which we find the object and the time relative to our prior experiences (or lack) with that object.

Understanding the transcendental aesthetic is based upon the dual non-empirical entities of space and time. Space, itself, does not exist - there is no space, there are only things. The objects that are there in the world around us are labeled as being in "space" to allow for a mental framework with which to understand how an object can be related to. As we experience objects (people, buildings, situations, places, etc.) we form immediate understandings of them. First, there is the sense of the thing, sight, hearing, taste, touch, smell, and then there is the categorization of perception that is formed immediately within the famework of our existing understanding of objects. Our brain immediately asks, is this similar to other things I already am aware of or is this a new object never before encountered? As we do not function well with objects we cannot categorize with others, we immediately seek to understand and "explain" the unique and new in relationhip to other things. If we know that objects hanging from trees are generally edible such as apples, avocadoes, and walnuts, then when we encounter a pinecone for the first time hanging from a tree branch, our understanding of fruit-trees allows us to make a comparison. but, visually, as the pine cone does not resemble other familiar fruit, we cannot understand it as fruit yet.

As we experience objects, the space in which we encounter them (or the context) is not an object itself - our concept of space, then,… [read more]

Limestone Sedimentary Rocks Term Paper

… Limestone

Sedimentary rocks that are made from the mineral calcite are called limestone. Calcite is found in the beds of evaporated seas and lakes. It also comes from sea animal shells such as clams, brachiopods, bryoza, crinoids and corals. Some limestone's can be nearly pure calcite, there is often a large amount or sand or silt that is included in the shelly debris.

Pure limestone is more or less white in color. The impurities that limestone contains such as clay, organic remains, sand, and few other materials make it white in color. Many novel limestones come in various colors especially on weathered surfaces. Limestone might be crystalline, clastic, granular, or huge; all in fact depends on the system of formation.

Limestone is most common in North America where it is used for architectural structures. Many landmarks across the world are made of limestone. This even includes the pyramids in Egypt. In Ontario, Canada so many buildings are constructed from it that is has been nicknamed the Limestone City. Limestone was most popular in the 19th and 20th centuries in the construction of banks and train stations.

Indiana is most notable for what is called Indiana limestone. This limestone comes from the Bloomington area and has been a source of high quality quarried limestone. Limestone is easy to cut into blocks or to make elaborate carvings. Limestone is very long lasting and stands up well to exposure. Limestone as well as marble… [read more]

Why Do I Want to Study Earthquake? Term Paper

… ¶ … Earthquakes

As a resident of California, few things have the ability to terrify me as the thought of a major Pacific coast earthquake. Earthquakes are terrifying for a variety of reasons. First, they are sudden and occur without any immediate warning. In addition, they are very violent; when major earthquakes strike densely populated areas, death and destruction is inevitable. Furthermore, while earthquake activity is heavily focused in areas that lie along major fault lines, earthquakes can theoretically impact almost anywhere, and their major damage can occur miles away from their epicenters. There are approximately half-a-million detectable earthquakes each year, about 100,000 of those can be felt by humans, and only about 100 of them cause any type of damage or death.

The element that makes earthquakes so terrifying is the fact that they are relatively unpredictable and sudden. Of course, it is incorrect to state that earthquakes are unpredictable. There are certain… [read more]

Spirituality Involves a Deeper Understanding Term Paper

… Spirituality involves a deeper understanding of what is happening around me. Being a more spiritual person means looking at what certain things mean beneath the surface. I believe that there is always more going on that what we can know and we should be open to that. Being spiritual also includes connecting with others. One thing that can be like a spiritual experience is riding the light rail. When I ride it to work, I always consider myself lucky because I can see the sun rising on the way to work and the sun setting coming home. The contrast of nature and man-made mechanisms is striking. My eyes are looking at the sky and yet I am hearing the noise of the light rail along with the strange smell I associate with it. Most of the time, there is a slight draft on the light rail, even when it is warm. In addition, I always grab a Sprite when I leave work so I associate drinking a Sprite with the experience of riding the light rail. The experience would not be the same if I could not see the sky. Because I love nature, the experience comes to mean more to me. I look at it and I am rejuvenated and the ride home becomes a ritual that I love.

The things that happen on the light rail can be spiritual. I am always looking for opportunities that can turn into positive experiences. These do not have to be life-saving experiences. Most of the time, they are not. For example, once I was on the light rail and I was running late for work. I was rushed and my bag was overstuffed. I could not remember if I had my badge for work with me and as I was looking for it in my bag, half of my bag spilled out on the floor. An elderly woman got up and helped me gather my things. She was handing items to me one at a time so I could put them in my bag. She did not say a word but she did smile as she bent down, picked up items with… [read more]

Earth Science: The Sculpting Term Paper


The objective of this work is to review the article entitled: "Magma P.I. 'Unearths Clues to How Earth's Crust Was Sculpted" published December 14, 2007 online the website 'Science Daily'.

The article entitled: "Magma P.I. 'Unearths Clues to How Earth's Crust Was Sculpted" published online the Science Daily website December 14, 2007 relates the work of John Hopkins University geologist Bruce Marsh who is stated to have "challenged the century-old concept that the Earth's outer layer formed when crystal-free molten rock called magma oozed to the surface from giant subterranean chambers hidden beneath volcanoes." (Science Daily, 2007)


Bruce Marsh has posited that the "deep-seated plumbing underneath volcanoes" is actually comprised of a system that is extensive in nature of "smaller sheet-like chambers vertically connected with each other and transporting a crystal laden 'magnetic mush' to the surface" and is a theory that is becoming accepted widely among scientists. This type of system has been termed a "magmatic mush column" and said to exist "beneath all of the world's major volcanic centers. It is held by Marsh that these channels, instead of simply transporting the magma and crystals needed in formation of the surface of the Earth involves a process in which the magma is pushed up through the earth and in doing so the earth's crust became fractured creating a type of "template" which guides erosion and sculpting that occurs in formation of "a series of valleys and mountain ranges..." (Science Daily, 2007)


Marsh holds that the functions he describes, at least in the region of Antarctica, "date back at least 180 million years to the time… [read more]

Earthquakes Charles Richter Determined That the Seismic Term Paper

… Earthquakes

Charles Richter determined that the seismic waves emitted from an earthquake could be used to estimate its magnitude, and he developed a calibrated system for measuring these waves commonly known as the Richter Scale (Earthquakes). The Richter Scale formula is based on the discovery that the larger the earthquake, the larger the amplitude of ground motion at a given distance from the quake. The Richter Scale equation is:

R (x) =.67 • log (.37x) + 1.46

R (x) equals the magnitude of that earthquake on the Richter scale and x equals the energy of an earthquake in kilowatt-hours (Earthquakes). The small numeric differences in values of R (x) can be misleading if one does not understand that the scale is logarithmic, which means that each whole number of the scale actually increases by 10. Thus, a magnitude 7.0 earthquake is ten times stronger than a 6.0; a 7.0 is 100 times greater than a 5.0; and a 7.0 is 1000 times greater than… [read more]

Regulatory Structure Policies and Process in Water Law Term Paper

… Regulatory Structure, Policies and Process in Water Law

The public trust doctrine, which keeps the state responsible for keeping certain natural resources exclusively available for public use, has influenced the way California implements its water rights system. The history of the doctrine's application dates back to December 19, 1914, when the California Water Commission Act was passed. This act made it mandatory for the state to determine who could exercise appropriative rights to California's waterways.

On February 17, 1983, a landmark decision for the case National Audubon Society v. Superior Court of Alpine County was made when the California Supreme Court decided to explicitly enforce the public trust doctrine within its water rights system. This meant that California's State Water Resources Control Board would have to now take public trust values into account whenever it reviewed any applications pertaining to water rights. Initially, the doctrine was used to only protect navigation, commerce, and fisheries. As time passed, its role was expanded to include the rights of fishing, hunting, swimming, boating,… [read more]

The GIS will be most accommodating and useful if it will change based on who is using it and who they are working with.

Formed to What Their Value Term Paper

… The melting point of cubic zirconia is an astoundingly high 2750 Degrees Centigrade! Colored cubic zirconia can withstand temperatures that are just as high as the ones that can be tolerated by the white colorless counterparts and does not experience color fading. In experiments involving very high temperatures using liquid oxygen, moissanite survived the temperatures where diamonds have been vaporized! [Anderson, B.W.: Gem Testing]

Diamonds come in all shapes, qualities and sizes and can be bought according to one's specifications and budget. The factors involved in purchasing a diamond, include clarity, color, cut and carat size. The diamonds have naturally occurring internal characteristics that are called inclusions. The diamond's clarity is largely determined by the size, nature, location and amount of inclusions the diamond possesses. A diamond's clarity grade affects its value and determines the price of that stone. Many diamonds appear colorless, but in reality they have light tones of yellow or brown in them. As the intensity of the tones become more pronounced, the rarity and the value of the stone directly decrease. [Schumann, Walter, Gemstones of the World]

Light entering the diamond reflects it

When a diamond is cut, most of the light entering the stone from any direction is reflected from the top and forming a display of sparkling flashes and rainbow colors. This is called dispersion. This creates a brilliant affect of colors and beauty.

Diamonds have the most unique characteristics any stone can possibly have. They have come to find uses in many different spheres of life. But their most significant use is in making beautiful jewelry, when a man wants to win a woman's heart he knows diamonds will do the trick!

Anthropological Analysis the Water Resources Term Paper

… Dissolved iron concentrations in ground water, particularly in wells, are the highest in ground-water discharge zones, especially near the south shore on Long Island. Another of the more serious disadvantages of natural ground water contamination is that the bacteria that accompanies and promotes iron bio-fouling also contributes immensely to iron encrustation and corrosion of wells, pumps, distribution lines, and treatment systems, subsequently raising the degree of expense another notch (Cartwright & Brown, 2003).

Supply problems & possible solutions

In spite of the marginal relevance of natural contamination, however, human activities associated with urban and agricultural land use continue to constitute the primary factors affecting the quality of streams as well as the health of aquatic life throughout Long Island and New Jersey. It is quite apparent that the water supply of New York is primarily affected as a result of the primary source of most public supply wells being contaminated, more often than not, as a result of natural contamination.

The degree of blame put upon human induced factors, however, is once again highlighted when acknowledging that although concentrations of most chemical constituents detected in stream samples generally meet Federal and State water-quality guidelines; current guidelines do not address many chemicals resultant to the combinations of pesticides, fertilizers, and industrial and fuel-related compounds (Ayers, Kennen & Stackelberg, 2001).

Taking into consideration the fact that the large population, extensive urban and industrial development, and, in some areas, agricultural activities, are the main causes of water-quality problems within New York as well as a number of other states; it becomes quite evident that there is no immediately effectual countermeasure that can be conveniently implemented. Natural contamination tends to affect the ground water resources, which are quite widely spread across New York, subsequently compromising most of the root sources for public supply wells, while human induced contamination is widely responsible for the contamination of other water resources. Taking into consideration the fact that the decontamination of ground water resources is rather inappropriately costly, it is apparent that focusing upon neutralizing and minimizing the degree of contamination to other bodies of water would be more suitable.

The proper, ecologically oriented regulating of power generators which release most of the acid-rain causing emissions that reach New York and the northeastern U.S. American acid rain emissions would be an effective initiative. Surprisingly, these emissions, as a result of the significant scope to which they travel, are also causing serious water quality problems in the Great Lakes and Canada.


Thus speaking and taking into consideration all that has been said in regard to the water supply problem within the State of New York, it is quite apparent that dealing with the human induced predicaments prior to the natural ones would be the more sound strategy to opt for; regardless of that, however, it is quite apparent that the degree of problematic issues related to the water supply within New York will be significantly dwarfed in the case of suitably effectual and appropriate measures not being taken… [read more]
