Lab 2 Report: Water Quality and Contamination Kristy Vasquez SCI 207: Dependence of man on the environment S. Tuckerman 01/12/2015 Clean Water Experiments The background of water quality and related issues can go back as far as the Clean Water Act. The objective of the Clean Water Act is to restore and maintain the chemical, physical, and biological integrity of America’s waters and their systems. Under Section 303(d) of the Clean Water Act, states, territories, and authorized tribes, referred to as an act of the state, are to publish lists of impaired waters. These waters therefore are technology based rules and are not harsh enough to meet the water quality standards set by the states. (http://water.epa.gov/lawsregs/lawsguidance/cwa/tmdl/glossary.cfm#section303d) Water quality research is very important to our society. This will help us protect our nations water systems, help us achieve a total maximum daily load of waste allocations on pollution. This will help sustain the ecological processes to support vegetation, fish populations, birdlife and our wetlands. (http://water.epa.gov/scitech/swguidance/standards/imp.cfm) The reason why this experiment is being done is to test my water system, and to determine the quality for life. The more we know about our water the better off we will be. I can easily tell the difference between hard water and filtered water. Texas is known for having hard water and comparing it to New York City’s filtration system is not very hard as the water is much purer. Doing these experiments and testing your water quality can provide you with information on contaminants that have inhabited your system. When looking back at the three experiments, I found that I accepted my hypothesis more than rejected them. In experiment 1 I was asked
