1: What contaminants were found in the surface water samples? What contaminants were found in the groundwater samples?
Metals, coliform, nitrites and pesticides/herbicides.
Coliform and acid.
2: Why might groundwater and surface water have different contaminants?
Can be exposed to things like nitrogen/phosphorus and can be exposed to sprays like pesticides and herbicides, while groundwater cannot be touched by these things because it is covered up underground.
3: Generally, farmers do not farm and industries do not build factories on the sides of mountains in remote wilderness areas. It usually not highly populated by people. What might explain the high nitrate level in the mountain water in this activity?
There might be the buildup of bacteria, which causes the nitrogen cycle. The nitrogen cycle creates the nitrites.
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 tracks the acidity of the water. pH can contribute to pollution because it can magnify the effect of other contaminants, meaning that it can make the pollutants stronger. Chemicals used in treating low pH are sodium hydroxides and any hydroxides that would neutralize the positive hydrogen ions.
5: 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 buildings have older pipes. The rusty and corroded pipes release the cooper and iron contaminants into the water supply of the old building. The newer buildings have newer pipes, there is no copper or iron in trace because the pipes have not rusted or corroded due to age.
