Pond Water Essay

“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

The data for Pond 5 were taken first on August 5th, with a temperature of 85.5°F, and wind was headed in a northern direction. Since Pond 5 is quite deep, the group took a small boat out into the middle of the pond about 15 feet away from the shoreline where the water is clear. The data for Pond 3 were taken on August 10th, temperature at time of experimentation was approximately 79.3°F, and wind was northerly. The group walked through the pond to the north of island 1 (Figure 2) and obtained the samples.

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.

We had to get exactly 25ml of water from the creek, and calculate the PPM of dissolved oxygen in it using a test kit. So, we went down to the creek, got exactly 25ml of water, and then we brought it back. We had to break a dropper in it and watch the colour of the water. We found that the colour matched 12 PPM on the scale; a deep blue. We collaborated with the other groups, and wrote down the other groups’ results to compare. We calculated that the average pH for the creek water was 7; entirely normal. We did some other stuff, like finding the number of rocks that neutralized acid in the creek, and vice

Slowly pour the water sample through the filter at a rate of about 2–3 mL at a time. Repeat so that at least 100 mL of pond water passes through the filter.

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

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

In each container, I put five fish. In one container, I put a portion of “Wolffia Brasilensis” in, as well as the fish flakes for food. In the control container, I put only the fish flakes. I planned to not change the water for a week to see the maximum discrepancy between the two containers.

Water is a necessity for human life and Earth’s environment. As the Earth’s population continues to grow we continue to strain the Earth for its water supply. Water pollution is when there is a biological change in the nature of the water biologically typically in a negative way. As water pollution began as natural causes through animals and other environmental issues as the increase in human activity over the years there was an expansion in water pollution. As the increase in contamination is obviously due to the excess of human activity due to the earth’s history it affects them the most. With Florida being a highly populated state surrounded by large bodies of water puts us at a greater risk of contamination. As Florida being a prime vacation spot the demand for clean refreshing water should be high, but with the ongoing water contamination the likelihood of that isn’t very high. If this continues then Florida's being a beautiful vacation home would turn into an environmental dump.

This paper discovers the water budget for Berkeley, California in comparison to Terre Haute, Indiana. The two cities precipitation differs throughout the twelve month calendar year where many of the heavy precipitation months are totally opposite. Berkeley California’s winters, where the majority of rain occurs and Terre Haute, Indiana where the rainfall is observed as consistently disseminated throughout the year evenly. This paper will also magnify geographic position, climate and elevation in contrast of the two cities that reflects the water budget outlined in Project 1: Water Balance defined in
