Parameters Of Measuring Water Quality Essay

In the article “Conducting Solutions” I learned an electrical current is just a flow of electric charge. When a metal conducts electricity its carried by electrons moving through metal. Did you know pure water only contains

We did 3 different test to help conclude the water quality. The first testing/station i did was to see what kind of critters were living in the water. Then, my next group was to take a test to see if eutrophication was in the water. We also took

Water quality is based upon a set of standards that describe the kinds and amounts of minerals and other substances that may be present in the water.

Dissolved Oxygen, pH levels, Temperature Change, Fecal Coliform, BOD, Nitrate, Phosphates, Turbidity, and Total Solids were each tested in the stream at least one time. If more time and enough supplies were given, then certain tests should be done more than once. Temperature Changes should be tested every other month because it is quick and a change in temperature can affect the health of the organisms living in the stream and therefore the quality of the stream. Temperatures can also drastically change in a short amount of time and there is a large difference in water temperatures in summer and winter. Another test that should be done every other month is dissolved oxygen because it is related to the temperature of the water. Cooler waters have a greater capacity for dissolved oxygen than warmer waters. This test is important because due to human activity and industrial processes, can increase water temperature and therefore decrease the dissolved oxygen levels. Certain organisms living in the stream need a sufficient amount of dissolved oxygen to survive. Another test that should be done more often is the

This makes sense because distilled water has most of its impurities removed. The conductivity of river water in the United States is anywhere between 50 S/cm to 1500 S/cm and industrial waters can be as high as 10,000 S/cm (EPA 2012). When we tested Sample 1, it had an average conductivity of 1223 S/cm which is on the higher end of the conductivity of river water in the United States. Sample 2 had an average conductivity of 222 S/cm which is on the lower end of the conductivity of river water. Sample 3 had an average conductivity of 1 S/cm, which is on the lower end of the conductivity for distilled water. Sample 3 was an outlier in this set of data. Sample 4 had an average conductivity of 215 S/cm which, like Sample 2, is on the lower end of the conductivity of river water. The well water had the highest conductivity and the city water from Bowling Green tested to have a conductivity of distilled water which was an outlier in our data. The other two samples, which were both from the University of Toledo campus, were about the

Unforeseen weather that reduces soil moisture levels and increases water temperatures would affect all of the four organisms I picked. In the algae population, this species would not be able to intake enough oxygen to grow, therefore, this population would suffer. Moreover, warmer water temperature would affect the feeding behavior of the ghost shrimp, starfish, and shark population. For example, the ghost shrimp would not have enough algae plants to feed upon, therefore, they would starve, which would lead to domino effect throughout the ecosystem. In addition, all of the three species reproduction schedule would change, thus, they would not be able to reproduce as many offspring as they would in a normal environment. This would lead to less

Measuring the water quality is important because water quality is absolutely vital for the river to be a healthy environment for the organisms around it. Water quality, if good, will support native fish, various microorganisms, various species of plants, and bird populations. The quality of a river’s water is commonly decided by its physical, chemical, biological and aesthetic traits. A healthy environment is one in which the water quality supports a healthy ecosystem; many of our own personal uses depend on the quality of the water that will be used drinking, fishing, recreation, and many other important uses.

The abiotic factors present in this ecosystem consist of temperature, light, water, minerals, and air. Majority of organisms living in this aquatic environment require specific temperatures to survive, although temperatures can vary according to the species. Obviously, water is a part of the aquatic environment, and is actually essential to all parts of life. Light plays a major part in the photosynthesis process for many organisms

Sediments are the main source of water pollution, contributing to turbidity issues as well as irregular or harmful nitrite/nitrate, phosphorus, and pH levels. This contributes to the death of marine organisms and can also change which organisms can survive in the body of water as its conditions change due to runoff. Anthropogenic runoff is also a contributor of adverse water effects, such as cultural eutrophication from fertilizer runoff, and also results in the death of aquatic animals and shifts in which organisms are more prominent in the ecosystem. This lab will address the effects soil will have on variables concerning water quality. There is also the option of including fish and/or aquatic plants in the water column, which are independent variables as well as the soil. The pH, ammonia levels, nitrite levels, temperature, D.O., and physical attributes are the dependent variables that will be measured during the lab. The qualitative physical tests (turbidity and odor) will portray the physical state and cleanliness of the water, as well as the level of runoff from the soil.

Abstract--Water quality is sometimes ignored by lake management until it affects fish production and aesthetic values and is significant to test the quality of lakes frequently, sometimes as many as multiple times a day since the water in the lake could be used as a drinking source for both humans and animals. Protecting the present quality of the lake is significant when it comes to avoiding future problems. Duckers Lake’s water quality was sampled in spring 2014. Variables that could measure the water quality of lakes include: dissolved oxygen (DO) levels, temperature, pH, turbidity, and phosphate and nitrates levels. Mean turbidity levels increased overall throughout the sampling dates, while pH seemed to decrease overall throughout

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.

In " Conducting Solutions" it tells you about energy moving through things. Pure water contains very few ions, so it does not conduct electricity very well. When table salt is dissolved in water, the solution conducts very well, because the solution contains ions. The ions come from table salt, whose chemical name is sodium chloride. Sodium chloride contains sodium ions, which have a positive charge, and chloride ions, which is have a negative charge.

All around the world, countries are fighting to keep their drinking water clean. Whether it’s streams, rivers, or lakes, countries have taken great measures to maintain high quality drinking water for both human consumption and animal consumption. Countries must first understand the sources of the polltion, then determine the best methods to eliminate the pollution. Clean drinking water is a valuable resource and a the key to human survival. Plants and animals also depend on water for their growth, so all water must be kept clean. The major contributors to water pollution can be classified in three categories, industrial, agricultural and municipal.

The question that was investigated for this lab was, “What is the water quality of the U-High creek based on microinvertebrates found in the creek?” The purpose of this lab was to determine the water quality of the U-High creek. To determine water quality 3 samples were taken from the creek, a water, soil, and algae sample. These samples were taken by digging up soil, collecting the water, and gathering pieces of algae from the sides of rocks. Then the samples were analysed to find the number and types of microinvertebrates in the U-High creek. The initial prediction for this lab was that the U-High creek has a fair water quality.

Almost every experiment had good results. The only to bad results were the pH- using strips and the turbidity. The pH - using trips was a 4 but doing the pH - using tablets had a 7. So it can go either way. Turbidity was 20 but that isn’t that high. The DO was 4ppm and that is almost perfect. That means that it has plants, but not a lot of them. The temperature of the pond was not cold and not warm. The temperature varies though throughout the seasons. There were 0 ppm results for the nitrates. That is very good. It doesn’t increase the plant growth but also doesn’t decrease the plant growth. The ammonia levels were also 0ppm. That means that the insects and animals don’t get sick by drinking the water or swimming in it. There were many bioindicators in the pond. There were water striders, tadpoles, grass, flowers, algae, gnats, and cat tails. The Voyager pond is very healthy and it should stay
