1: What contaminants were found in the surface water samples? What contaminants were found in the groundwater samples?
Bacteria, Pesticides
2: Why might groundwater and surface water have different contaminants?
The density might be different so some of the contaminants might go down
3: Generally, farmers do not farm and industries do not build factories on the sides of mountains in remote wilderness areas. These areas are usually not highly populated by people. What might explain the high nitrate level in the mountain water in this activity?
The nitrate levels can increase and there isn't no one there to stop it
4: What is pH level, what are its characteristics and how does it contribute to pollution? What chemicals are used in treating low pH levels?
pH level is the acidity level, if the acidity level gets to high the fish can die there will be no more oxygen in the water, Sodium Hydroxide is added to treat the pH level
5: Water in an old building, tested recently, showed high copper and iron content, and low pH levels. A water reading taken 20 years before showed low pH levels, but only minimal traces of copper and iron. If none of the new buildings on the same street showed signs of metallic contaminants, but all reported lower than normal pH readings, how might these readings be explained?
The older the building the more time copper has to be released it takes time for those chemicals to be released from the metals used and the paint
