Abstract

The purpose of this experiment was to compare different states’ tap water with respect to pH, bromine, cyanuric acid and hardness. Free Chlorine, Iron, Copper, Lead, Nitrate, Nitrite, Total Chlorine, Fluoride, Lead, Carbonate, and Total Alkalinity data will be included if statistically nominal. The hypothesis for this experiment is that northeastern states will have better water quality due to the increased amount of total rainfall compared to southern states. The procedure for this experiment included immersing the water test strips into the solution of water from each state. After two to three weeks, another trial for all of the states were conducted. The first trial’s data showed a constant pH of 6 throughout the country; Cyanuric Acid levels were high in Atlanta, Georgia; Charlotte North Carolina; and Key West, Florida. Regions located in the south, such as Charlotte, North Carolina; Atlanta, Georgia; Key West Florida; and Dallas, Texas all contained high Copper levels. Philadelphia, Pennsylvania; Bangor, Maine; and Key West, Florida contained high amounts of Nitrate, with only Key West, Florida having a high amount of Nitrite. Even when St. Louis, Missouri had a hardness level of 120, all of the other regions contained hardness levels from 25 to 50. In conclusion, states in the southeastern region of the United States have worse water than northern states. Key West, Florida showed to have the worst water in all of the tested regions.
