The Chemistry And Physic Of Either River Or Lake

Hydrologic studies has always been the subdiscipline of environmental science that has most intrigued me; probably because the eco- and geological systems that comprise surface and shallow groundwater systems are so inexorably entwined and very delicate. Both of the virtual labs were interesting, and paint a clear picture of how we affect our hydrosphere and how that, in turn, affects us. Spotsylvania County and the city of Fredericksburg share four water treatment facilities that pull water from the Mott's Run Reservoir, the Ni River, and the Rappahannock River, which is the largest river in the local area, the other two being smaller tributaries that feed into it. The Rappahannock River is a significant body of water, providing the potable water for roughly a quarter-million people. Toward the coast the river sees mostly recreational and some light industrial use, and further upstream it is affected by many small to midsized agricultural operations that take place on the land adjacent to the river.

Water is an important resource and weather agent in our world, and the Great Lakes Region has an intimate relationship with water. The region was shaped by glaciers long ago and continues to be shaped by flowing surface water today. Groundwater is very pure in the area, which allows for plants, animals, and humans to thrive there. Migration into the area can be related to the groundwater found there. Human use of the water results in man-made structures, water flow alteration, and changes in water quality. Water is very influential in the Great Lakes Region.

Water: a necessary facet to all living things. For animals, water can be a home or a drink. As for humans, the uses of water are endless. Not only do we use water as a beverage or washing clothes or dishes, but we also use water for toilets, various kinds of plumbing and other things that aren’t as easily identifiable. As of 2005, this 70% of our Earth has been manipulated and used for thermoelectric power (41.5%), irrigation (37%), domestic affairs (8.5%), public supply (5.4%), industry (5%) and aquaculture (2.6%).1 The importance of water is infinite, not only to our way of life, but also our lives. We need to drink water to ensure the health of individual cells of the body, lubricate joints, moisten mucous membranes of the organs and many other vital bodily functions.2 Not only do we expect the availability of water, but it is highly important to humans and all living things. Although it is such an integral part of our Earth, one may ask about some of its properties and characteristics.

The community issue that I have chosen is our lake here in Edinboro, PA. The problem with the

Water is essential for life as we know it on earth. It is used by plants

Overall the objective of this lab exercise was to introduce students to watershed ecology and the ecological factors that affect water quality. Students used biotic (macroinvertebrates ) and abiotic indicators to asses the quality of water in a freshwater body. Specifically students collected water chemistry data (hardness, nitrate/phosphate concentrations, dissolved O2 and pH) to asses the quality of water. Additionally macroinvertebrates from the benthic environment of a respective field site were collected, analyzed as well as catalogued. Collectively the results indicated that a greater species diversity was indicative of greater water quality(Lenat). Likewise within a freshwater ecosystems a negative correlation was found to exist between fluctuating abiotic factors,species diversity and water quality. It can be concluded that amongst the three field sites the ranking of water quality from highest to lowest is as follows; Great Brook Farm, Russell Mill pond, Lawrence Street Stream.

The river taught me that I, along with a great majority of humanity, need to readjust the way in which we view our world and our position in the world. Humans have been predisposed to think of themselves as rulers of nature, separate from the plants, animals, water, etc. This has allowed us to exploit nature, and specifically in this case water. The Little Miami River used to sustain all form of life thousands of years ago, but now humans have made its waters undrinkable. We have degraded the river water in order to perform functions, such as disposal of waste, for our convenience. Humans can no longer view the river, or nature in general, as means to accomplish a goal or else we will only increase the destruction of Earth. Nor can humans

Water was collected using a Wan Dorn Bottle (Lab Manual). There were approximately 20 students that collected samples from the deepest part of the lake, and 20 students that collected samples from the shallowest part of the lake. The shallower portion of the lake was closest to a golf course and floating vegetation (Lab Manual). Five water collections were made at each location. From the deep part of the lake, each of the five samples was taken at 1m; from the shallower part of the lake, each of the five samples was taken at a 0.5m depth (Lab Manual). These water samples were collected into 5 separate bottles, each labeled one through five. Bottle one had water nearest the surface, whereas bottle five had water collected deeper in the lake. Bottles two through four were intermediate levels of one and five. We used the water in the bottles labeled 1, 2, 3, 4, and 5, to detect the temperature and test the pH of the water samples from the various depths of both locations. Water from the labeled bottles 1, 3, and 5 were put into bottles labeled N1, N3, and N5, and were brought back to the lab to analyze their nutrient content (Lab

The River simulation created a hypothetical circumstance in history involving a drought, competition for resources, alliances, and betrayal. The task was to acquire enough water for your village to survive. As the village or group with the most manpower would conquer the wars, the object was to ally with as many trusted villages as possible. Throughout history, the world has exhibited many similar situations between different countries. The North American Free Trade Agreement (NAFTA) is a trading alliance between the United States, Mexico, and Canada. Similarly, Titan created a military alliance with Callisto and Io. In NAFTA, each country benefits by not paying tariffs when trading between each other. As in the river simulation, the three

The results for DO include 12/3/12: 3.2 Mg/L, 13/3/13 29 Mg/L, 14/3/14 66.73 Mg/L or % saturation? 15/3/15 92% saturation, 15/9/15 85% saturation. I think 66.73 result was % saturation so that is the result I am using. Recordings of Freshwater Creek on the 22nd of February 2016 show results of DO in both Mg/L and % saturation, these results are 6.32 Mg/L and 80% saturation and for air temp 27.13 Degrees Celsius. Resource 4 shows that water and air temperature coincide with the amount of average/normal Mg/L of DO and Degrees Celsius. For 27.13 Degrees Celsius the Mg/L should be around 8, since the result is 6.32 Mg/L this is under normal amount, however it is not at 0 so the water isn’t completely contaminated/polluted. The year 2012 DO was at an extremely low 3.2 Mg/L this could have been a migration of fish such as tilapia which may have caused many fish to die off, however the next year the Mg/L was at 29 which may have been a direct result of either migrant fish killing off other fish or flooding which killed fish. A significant trend to result was the temperature were the temperature only fluctuated by less than 1.5 degree (resource 5) however that trend is broken due to 2016 results of 27.13 Degrees which is an unusual result due to the

EDTA titration, as well as AA (atomic absorption spectrophotometry) are two main ways in which water hardness is measured. EDTA is performed by adjusting the pH of the water with the use of a buffer, then adding an indicator to the solution, which will turn red if calcium ions are present. If only magnesium is present in the solution, it will remain blue. Then an EDTA solution is added to the solution. The complete reaction of all calcium and magnesium ions with the EDTA solution is represented by the change in color of the solution from red to blue. (Thomson, 2014)AA, or atomic absorption spectrophotometry, is performed by turning the water into an aerosol, which is then burned, and the internal computer system of the machine uses the absorbance of light to provide a number which corresponds to the concentration of ions in the water sample. (The Royal Society of Chemistry Fine Chemicals and Medicinals Group). It is important to use more than one method to measure water hardness, especially a method which relies mainly on the use of technology, to lower the possibilities for human error, as well as to provide multiple values of hardness for comparison.

Question: Does the depth of the river affect its overall pH from mid december 2015- to early january 2016?

On Wednesday April 12, the 8th grade class of Stanley Clark went to Smith Residence Thornacres Drive Niles, Michigan to observe and take multiple tests on the river. The latitude and longitude is 41°49’47.1684 “N 86°15’15.0372 “W. On this day the students observed that the water of the river was cold at 13°C and appeared to be dirty and had slight bit of muckiness. The flow of the water seemed to be flowing rapidly. The velocity of the water was 42.12 seconds per 100 meters. The weather conditions on this day appeared to be cloudless with a radiant sunshine and a cool breeze. With a temperature of 11°C. The temperature ranges from 4°C-22°C, the worst weather appears in rain showers. On the other side of the banks there is a farm with

In recent years, land use practices have increased tremendously, affecting river biodiversity and causing negative effects on ecosystems (Fierro, 2017). Different studies have shown that the health of ecosystems correlate to location and the amount of land usage near those locations. The objective of my study was to find how land usage has affected the biodiversity of streams in my own community by studying two different streams, Orange Trail Stream and Lily Branch. The study of the health of streams is important because it allows the population to understand how different land usage practices negatively affect the ecosystem and water quality. To test the health of stream ecosystems, one would conduct a bioassessment. A bioassessment is a
