pH in water does not pose an issue for humans, as acid rain has a pH of 4, compared to orange juice (pH of 3). However pH poses as a serious issue for certain organisms. A common issue are "dead lakes," where because of the acidity, not many organisms live in the lake. A normal lake has a pH of 6.5, but an acidic lake has a pH of 4.2-4.4. This does not allow for the survival of snails, clams, bass, crayfish, trout, salamanders, or perches. These lakes are known as dead lakes

Bedrock composition can cause a change in pH. Limestone can remove some of the acidity from groundwater, while granite does very little to the pH value of the water. The amount of organic materials can also lower pH. As these. Begin to breakdown, Carbonic acid can form, slightly lowering pH values.

Acidic:
pH reading less then 7
Basic:
pH reading greater then 7
Neutral:
pH reading of 7
Point Source Pollution:
A source of pollution that can be identified
Non-point Source Pollution:
Pollution that comes from many different sources

Acid rain is caused from SO3 and NOx chemicals caused by the burning of fossils fuels when combined with water vapor in the clouds. When precipitated back into the ground with a pH of 4.3 which is acidic and dangerous for the environment. The acidic rain seeps into ground water contaminating clean water.

The creation of extra greenhouse gasses can make precipitation acidic, making the watershed that it precipitates into more acidic. Foreign chemicals that enter a body of water raise or lower the pH as well. Shampoo can lower the pH value, while Industrial chemical dumping can cause the pH to raise or lower extremely. Coal mining creates sulfuric acid, which raises the pH of the local groundwater.
