In this lab we tested the purity of water by looking for the chemicals free chlorine‚ chloride‚ sulfate‚ nitrate‚ copper‚ total hardness‚ iron‚ hydrogen sulfide‚ lead‚ pesticides‚ pH‚ total alkalinity‚ and total chlorine inside a water sample. The chemicals that produced a 0.0 result meant that there was no trace of that chemical inside the sample. The chemicals not found were copper‚ hydrogen sulfide‚ free chlorine‚ lead‚ iron‚ pesticide‚ and total chlorine. As a class we found the results of

versus environmental deterioration also has created a debate. Some economists argue that the on-site impact of soil erosion and other degradative processes are not severe enough to warrant implementing any action plan at a national or an international level.
