The purpose of this experiment was to determine whether or not Moyer's Landfill affects the pollution level of the Skippack creek that may create hazardous environmental conditions for organisms living there. To perform this experiment, various tests were completed upon two different sites (one upstream of the landfill and one downstream of the landfill) checking to see if the tests stated that the pollution level downstream was greater than the one upstream. The four tests that were per formed were a wide-range pH test, a dissolved oxygen level test, a nitrates level test and a phosphates level test. Each test was performed using a different procedure and a different set of materials. The pH test was performed to determine whether the water was acidic or basic. The dissolved oxygen (DO) test was used to determine what the level of DO was in the site for aquatic life to live off of. The nitrates and phosphates level tests were used to determine the amount of the two signs of pollution.

After completing the experiment it was found that the pH level was 13% higher downstream than upstream, the dissolved oxygen were too similar to make any predictions, the nitrates were 15% higher downstream, and the phosphates were 15% lower downstream clearly showing that the landfill is creating an effect on the water pollution.
