“The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity (sic) of the solution. The letters pH stand for power of hydrogen and the numerical value defined as the negative base 10 logarithm of the molar concentration of hydrogen ions.” (PH, 2002). The pH scale is from 0 to 14. When the pH is higher, the hydrogen ions are fewer and the substance considered alkaline. This means when a pH unit increases by one, there is a tenfold change in the hydrogen ion. For example, if a substance has a 7 pH, it has 10 times as many as hydrogen ions available as 8 pH. A lake having a water pH between 6.5 and 8.5 is considered to be neutral. Researchers tested Peckham Park lake water monthly from August 2015 to April 2016 for water pH levels. A water quality PH test strip taken from a jar and dipped into the lake. After a few minutes, the strip will turn a color and this color determines the pH. The jar the strips came in has a chart of the colors on the back which compared to the color on the strip. The lake tested monthly using the PH test strips, which show the pH level, hardness, toxic, etc. using color-change

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

Introduction: The purpose of this research is to determine whether there has been a change in the overall water quality of the Lake Tarpon Basin, and if so, whether the quality has improved or worsened. The variables that will determine whether the quality has changed are: nutrients (phosphates and nitrates) and dissolved oxygen (DO). The expected changes are lower dissolved oxygen levels (from the already low levels), higher nitrogen levels (from the already high nitrogen levels), and the state qualifications still are not met for nutrients and dissolved oxygen (Levy, Flock, Burnes, Myers, Weed, River 2010). This topic relates to environmental management because the changes in water quality would be due to pollution, which relates to the question “How does human activity lead to the pollution of water stores?” The hypothesis that will be tested is that Lake Tarpon’s water quality will have worsened since the last measurements by Levy, Flock, Burnes, Myers, Weed, and Rivera in 2010.

6 groups each collected a sample of surface water from the wetland and the lake in various areas. Back at the lab, measurements were made and analyzed the data. We had 23 samples of water slides from the samples of water collected from each location. We examined the drops of water from each location under a microscope and counted all the microorganisms we could find and recorded them in Microsoft Office Excel. After looking at the water samples under a microscope, we tested the pH level of 6 samples from each location of water with a Vernier pH probe and recorded this data in Excel. The number of microorganisms found in the recorded was analyzed using a statistical chi-squared test and the pH levels recorded was analyzed using a t-test.

To assess and analysis the long term trends and seasonal trends of Phosphorus in relation to the lakes system within the catchments.

2002), phosphorus levels in soil within the watershed and in surface water samples will be considered to determine the potential sources of nutrient loading into the lake. Different samples and analyses for Phosphorus concentrations (and hereafter we call Total Phosphorus – TP) in brooks and ponds of the ML watershed gave us a panoramic view of nutrient sources streaming to the lake and how they could disperse and redistribute in the lake waterbody. The term ‘Total Phosphorus’ has to be understood as all forms of Phosphorus which may occur mostly in Phosphates (PO4) and Organic Phosphates.

The quality of lakes around the world are slowly being decreased, due to factors such as pollution, littering, not enough exposure to sunlight, and generally a clack of biotic factors. This is why it is important to assess the health of lakes around the area and analyse if the lake is habitable and healthy. The lake that will be assessed is Lakewood Lake, located in the Brisbane area near Lakewood. The health of Lakewood Lake is in question as biotic and abiotic factors will be tested to assess the health of the lake. Biotic factors such as living organisms or and form of wildlife around the water, and abiotic factors such as the temperature of the water and air, pH levels, dissolved oxygen, conductivity in the water, the moisture and pH levels

In conclusion, the water is not that polluted, according to the test results. Mostly all of the results were excellent, but only 2 of the results were fair, which is in between poor and excellent. Therefore, the water is not

The CTDEP collected bottom- dwelling fish and invertebrates and compared the quantity of organisms and number of species with the levels of oxygen in the water. Both of these studies confirmed that severe effects occurred whenever levels of oxygen fell below 2.0 mg/l. Large reductions in the numbers and types of aquatic life present were noted. The lab experiments recorded reductions in both growth and increase in death.

Our plan is research the phosphorus levels in Lake Monroe and Griffy Lake and compare them in terms of area surrounding and the impacts it has on the City of Bloomington. Due to the proximity of agriculture around Lake Monroe and Griffy Lake, we want to research the effects of agricultural practices such as pesticides on water. Specially, we want to see if there are differences between the body of water we use as a drinking water source, Lake Monroe, and Griffy Lake. We think it will be beneficial to compare the chemical levels in both bodies of water and evaluate the differences.

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: During this lab, the pH of water in soil from a man made garden, a deciduous forest, and a river bank were tested after leaving it in containers for one, two, and three hours, coming out to a total of three trials with three different soils all together. After testing the pH of the water when being added to the soil for the desired amount of time and comparing it to the original water with no soil added, is then when each pH difference was observed and recorded in a a notebook, while pictures were taken of the experiment being conducted.

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.

When I first saw we had to read a book for this class, I was not that happy about it. However, this book was so fascinating to read, and I learned more than I thought I would. The beginning of the book freaked me out because Kolbert mentions that we’re in the middle of a mass extinction. I couldn’t wrap my mind around the thought of the human race becoming extinct. Every time I think about that, I always remember that documentary/movie called Life without People we watched in eighth grade. For her to talk about how the human race isn’t as superior as we think is eye opening. Also, it was surprising to learn that Kolbert was a journalist, and that she wasn’t some scientist. It showed me that you don’t have to limit yourself to just one thing. She took her field of journalism and paired it with a journey to find out what is happening to the Earth.

The question being investigated is, what is the water quality of the UHigh creek based on invertebrates found in the water? The water quality is determined by the dissolved oxygen, the pH level, the nitrogen levels, and phosphorous level. The dissolved oxygen is the amount of oxygen molecules mixed in with the water molecules. If the dissolved oxygen level is low, then the water will become polluted. Dissolved oxygen range is 1-14 parts per million or milligrams per liter(Riverwatch). The aquatic organisms need these dissolved oxygen molecules to breathe and survive. Another factor for measuring water quality is the pH levels. This measures the acidity of different solutions in the water. A pH range of 6.5-8.5 is considered safe for aquatic life. Another factor for measuring water quality is nitrogen. It is found as ammonia and the content of nitrogen in the water should be no more than 1.3-2.2 mg/L. If it is above this range it can
