Comparing Chemical Levels

“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

Government agencies carefully monitor water quality and its effect on wetlands (Reference: Environment Protection Agency Wetland Report EPA 832-R-93-005). Of particular concern is the concentration of nitrogen in water draining from fertilized lands. Too much nitrogen can kill fish and wildlife. Twenty-eight samples of water were taken at random from a lake. The nitrogen concentration (milligrams of nitrogen per liter of water) was determined for each sample. The variable in this information is nitrogen concentration (mg nitrogen/l water).

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.

There could be a hypothetical leak into lake michigan. All of the great lakes are connected so the leak from lake erie is able to travel to any other body of water i tis connected to. In order for the leak to travel to lake michigan the chemicals would have to travel through Lake Huron first. This is a large lake and it would take a while to get to Lake Michigan through lake Huron. Even though there is a great distance between Lake Michigan and Lake Erie, the Phosphorus could definitely travel through Lake Huron overtime. Not only are the chemicals able to be transported through lake heron, but it can also be transported through the underground water like the water tables. Therefore, this plant should be labeled as a possible source of

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

This analysis of case studies from Los Alamos National Laboratory, and the case study to predict the effects of pesticides on aquatic systems and the waterfowl that uses them. Comparing the two processes of these case studies, along with analysis of the assessments. Describing the case study on the effects of pesticides in aquatic ecosystem, the risk assessment correlated to observed field studies and evaluate the importance of this type of correlation in general for all risk assessment efforts. Breaking down the ecological and social

Through our research we aimed to determine if there were any differences in water quality of both the north and south forks of Strawberry Creek. As time progresses and the environment changes it is important to keep track of how certain species are being impacted by these features, and how they cope with change. We hypothesized that due to the lack of pollution, the south fork will promote a greater diversity of macroinvertebrates. This was due to the fact that there was less runoff and trash that could be introduced to the water in the south fork, than there was in the north fork. We gathered data by analyzing the different organisms living in both forks. We collected a total of fifty vials composed of five organisms from each fork, and inspected them under microscopic view. After gathering data and identifying the different kinds of organisms living in the different forks we assessed whether the organisms from the samples could live in high or low resolution water. We also took a t-test to assess the probability of these differences being due to relevant factors or by chance. Our major findings suggest that organisms in the south fork showed a higher demand to living in cleaner water indicating that our hypothesis was correct.

There is an overpopulation in the largemouth bass population due to the fact that there isn’t as many people fishing largemouth bass as they usually did. At the year 2001, the amount of largemouth bass caught decreases by about 600 fish. Which leads on to the fact that the largemouth bass population increases when their main predator isn’t killing them as much and leads onto a overpopulation. The ph levels are turning more acidic by decreasing to the ph level of 5.5 . This causes the the food sources for the fish to have slower reactions which allows them to die easier and causes the food source for the fish population to be low. Missing information that would be valuable to the continued analysis of the problem or would better identify the initial causes of the problem is to show how much pollution comes to the tri-lakes and to see where it comes form during the years of 1988-2008. This would allow me to see if pollution is really the problem to the ph levels. Policy recommendations that I would make to helps the Tri-lakes economy be better is for allowing the amount of fish caught to rise due to the fact that the amount of fish are overpopulating. Also to allow only a certain amount of waste can get into the lake to stop the ph levels turning acidic. An example is for people to clean their boats before fishing in the lakes to prevent more bacteria or chemicals entering the lake. Also to monitor over the pollution or waste from the

The Effects of Nitrogen and Phosphorus Enrichment on Water Samples from Encanto Lake and the Rio Salado River.

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.

The culprit this time around is the farmland that makes up 63% of the Lake Erie watershed, or, more specifically, the potent phosphorous fertilizers being improperly applied to the land (McLean et al., 2014). Growing demand for food has placed increased pressure on farmers’ crop production, so many farmers compromise using more fertilizer less efficiently in

REMIEDIATING AGRICULTURAL WATER CONTAMINATION Remediating Agricultural Water Contamination: Problem, Solution, and Barriers Paper Problem Concerns about water pollution are generally focused towards sources that are highly visible and chemically oriented. However, the greatest causes of water contamination and quantity abuse in the United States come from agricultural production (United States Environmental Protection Agency [EPA], 2012a), which is defined as a nonpoint source that pollutes with nutrients. In 2011, nine

Chemical equilibrium is the study of change within a chemical reaction and how far it will go to reach a dynamic equilibrium (Burdge). Dynamic equilibrium is defined as the constant movement of species in a chemical reaction, gone to incompletion while the rates of production and consumption are equal (Kf = Kr ) (Burdge). It differs from static equilibrium in that species are constantly being consumed and produced, it is dynamic movement (Fox). The concentration of such species do not change, it remains constant (Fox). The rate at which species are being consumed and produced is known as the equilibrium constant (K) (Burdge). Due to the fact that the concentration

Aim: The aim of the lab “Chemical Equilibrium” is to observe the effects of changes in concentrations of products and reactants on the position of the equilibrium of given chemical reactions.
