GEOLOGY

Detailed explanation-1: -clogging narrow streams and preventing water from flowing properly. causing rapid algal growth that decrease oxygen levels and choke aquatic life.

Detailed explanation-2: -Overflow during a heavy rainstorm from a wastewater treatment plant would result in-over-treated drinking water.

Detailed explanation-3: -Too much fertilizer can actually kill the plant and excess fertilizer can runoff into streams and lakes causing toxic algal blooms that are harmful to aquatic life and even people and their pets. Excess fertilizer runoff from lawns and agricultural applications also contribute to aquatic “dead zones” in coastal areas.

Detailed explanation-4: -Subsidence-sinking of the ground because of underground material movement-is most often caused by the removal of water, oil, natural gas, or mineral resources out of the ground by pumping, fracking, or mining activities.

Detailed explanation-5: -Runoff from agricultural land carries chemicals from fertilizers that collect in a lake. The buildup of chemicals can eventually cause-rainfall levels to drop causing drought and a shorter growing season. river tributaries to reroute, changing the flow of natural waterways.
