Abstract

In these experiments that we have conducted, we used oil, vinegar, laundry soap, and soil to simulate contaminated groundwater. We then constructed a variety of filters to attempt to clean the ground water and make it drinkable. We also tested various bottled and tap water for certain chemicals.

Introduction Many areas have water containing impurities from natural or artificial sources. These impurities may cause health problems, damage equipment or plumbing, or make the water undesirable due to taste, odor, appearance, or staining. Those impurities which cause health problems should be attended to immediately; other problems caused by water impurities can be corrected if they are a nuisance. Before beginning any treatment plan, have water tested by an independent laboratory to determine the specific impurities and level of contamination. This will help you select the most effective and economical treatment method. (Ross, Parrott, Woods, 2009) The reason why we conducted this experiment is to test the filtration to remove oil, vinegar, and laundry detergent has on soil before it reaches groundwater. These chemicals go to our local water supply, but first it goes through the soil.

Materials and Methods
The materials and methods section should provide a brief description of the specialized materials used in your experiment and how they were used. This section needs to summarize the instructions with enough detail so that an outsider who does not have a copy of the lab instructions knows what you did. However, this does not mean writing every little step like “dip the pH test strip in the water, then shake the test strips,” these steps can be simplified to read “we used pH test strips to measure water pH”, etc.
