Groundwater Lab Analysis

The hypothesis stating if four grapes are placed in distilled water, a salt solution, a sugar solution, and tap water, then the grape placed in distilled water will gain the most mass out of the four grapes was rejected by the data. The grape placed in the distilled water gained the second smallest amount of mass in the experiment, 0.26 grams. The hypothesis stating if four grapes are placed in distilled water, a salt solution, a sugar solution, and tap water, then the grape placed in the salt solution will lose the most mass out of the four grapes was rejected by the data. The grape placed in the salt solution gained a mass of 0.22 grams. The grape placed in the salt solution gained 0.22 grams of mass, the grape placed in distilled gained 0.26 grams of mass, the grape placed in the sugar solution gained 0.55 grams

In the Chemistry of Natural Waters Lab we were to collect a sample of water, ranging from a fountain, stream, bottle, or tap water. After we collected the samples we all did many tests to see what the hardness was for each one. Water hardness is determined by the amount of Calcium and Magnesium in the water.(2) Water that has more Calcium or Magnesium is considered to be harder than water with less of those two elements. When you use soap and detergent, this is where you see water hardness coming into play in everyday life when you are washing things.

There are three main mechanisms by which the chemical composition of groundwater, which is our natural source of drinking water, may be changed: by natural processes, by man's waste-disposal practices such as those for sanitary wastes, liquid industrial wastes, solid wastes, and radioactive wastes, and by spills, leaks, and agricultural activities and other sources unrelated to disposal. The degree of risk posed by contaminants varies according to many factors. These include the volume and toxicity of the contaminant, its concentration in the aquifer, its persistence in the environment, and the degree of human and environmental exposure to the contaminant. In addition, the number of persons affected, or likely to be affected, over time and the percentage of available groundwater both locally and regionally should be taken into consideration. If the contaminants in the groundwater exceed the standards set for drinking water by the federal government, for example, then the water is hazardous for the use for which it was designated under the standards. These standards include, however, only a limited number of chemicals, and thus they do not necessarily protect humans or the environment against either the short-term or the long-term effects of every contaminant that might be found in

In the three lab visits to different steam, rivers, and watersheds the method in which we conducted to record our answers have been consistent. The way we conducted the studies have been done the same way for each visit. At each site we used a small table to hold items that will be used, kick seine nets, vernier kit, temperature sensor, pH sensor, conductivity probe, and dissolved oxygen probe. Also needed are data sheets for each different watershed to record the temperature, dissolved oxygen, conductivity, and the pH. You will also need water waders to be able to go into the water. As well as two small contains that you will fill up with water at each site, help when catch insects from the water with the kick seine net. Ice cube trays that

Conclusion After performing multiple tests on the known compounds, the identification of sodium chloride being the unknown substance was confirmed. With this now known information, the waste can properly be disposed of by the EHS. The objective of successfully identifying the compound was achieved.

Studies have shown that near shore, and in rives tributaries to the Great Lakes the PPCPs levels have a higher risk quotient. The risk quotient being the ratio of maximum measured environmentally concentration to the predicted no-effect concentration of the pollutant. Using this ratio, 38 compounds were detected from effluent or Lake Michigan samples with four compounds being detected at levels greater than 50% frequency. These compounds found at all of the sampling sites in Lake Michigan and the Milwaukee Harbor are: metformin (100%), caffeine (97.6%), sulfamethoxazole (83.3%), and triclosan (71.4%). The mean and maximum levels from the samples can be found in Table 2, along with the minimum detection limit, minimum quantification limit, and maximum value found in the method

Introduction: The purpose of this lab was to find the relative solubilities of some salts of the Alkaline Earths and use that information to find the order which they appear in the periodic table; also use that information to efficiently find an unknown alkaline earth halide. Also to find the relative oxidizing powers of the Halogens given and using that information finding the order of the Halogens in the periodic table; also use that information to efficiently find an unknown Halogen.

Groundwater pollution is a major problem that is growing in all over the world. Of course the united states America also facing this problem. People of Mississippi State are worried about groundwater pollution due to the several human activities. Groundwater is a main source of their water supply. Disposal of solid waste in landfills is an economic option for many municipalities in developing countries where alternatives like incineration and composting are costly. However, groundwater pollution from the leachate generated within the landfill and migrating through the bottom liner material into the underlying groundwater aquifers remains a major public health concern I studied chemical parameters of groundwater in Alcorn State University as a part of my project.

California is sinking!,groundwater bill regulations are making it through the state legislature.This bill will require local agencies to track or even restrict groundwater pumping.Farmers are against this regulations,they fell is a violation of their land

Before executing the chemical tests, the unknown went through a physical examination, where it’s physical properties were observed. As shown on Data Table 1, the given unknown was a pale-yellow liquid with a vinegar-like smell. The class of the carbonyl couldn’t be determined based off

Interactions between groundwater and surface water are complex. Consequently, groundwater pollution, sometimes referred to as groundwater contamination, is not as easily classified as surface water pollution.[7] By its very nature, groundwater aquifers are susceptible to contamination from sources that may not directly affect surface water bodies, and the distinction of point vs. non-point source may be irrelevant. A spill or ongoing releases of chemical or radionuclide contaminants into soil (located away from a surface water body) may not create point source or non-point source pollution, but can contaminate the aquifer below, defined as a toxin plume. The movement of the plume, a plume front, can be part of a Hydrological transport model or Groundwater model. Analysis of groundwater contamination may focus on the soil characteristics and site geology, hydrogeology, hydrology, and the nature of the contaminants.
