Unit 6.4 C.10
Explain the role of septic and
sewage systems on the quality of surface and ground water.
Unit 6.4 C.11
Explain how human activity may impact water resources in
Connecticut, such as local ponds, rivers and the Long Island
Sound ecosystem.
|
1.) Identify a favorable environment
for life
-water, shelter, source of energy,
community of life, food web/chain
2.) Identify the major parts of working septic and sewage
systems
Groundwater: Saturation Zone, Unsaturated Zone,
Aquifer, Water Table, Groundwater, Runoff, Surface Water
Septic System (Individual Water Treatment): Septic
Tank, Sludge Layer, Porous Pipe, Drain Field, Whole System
Overview (House to ground, and back)
Sewer System: Pipes, History of Sewer Systems
(Chicago) and Disease
Water Treatment Facilities (Urban Water Treatment –
WEST HARTFORD): Primary Treatment, Secondary Treatment (Sand
Beds or Bacteria), Tertiary Treatments (Chlorine)
3.) Analyze the differences and benefits of each water
treatment option (septic and sewer) and their effect on
groundwater and surface water.
4.) Identify the major types of Water Pollution (Runoff,
Point, Non-point)
-Agricultural, Manufacturing,
Pesticide, Urban pollutants
5.) Analyze and evaluate how small changes
in water quality can affect aquatic environments.
6.) Evaluate the effect of the above objectives on water
supplies, animal and plant life, and human behaviors.
7.) Identify and analyze the pros/cons behind desalination
8.) Formulate appropriate human actions to preserve water
quality
