APES Solid Waste and Ecological Footprint Reveiw

CERCLA (Superfund)

Cleans up and provides money for hazardous waste sites

RCRA

“Cradle-to-Grave” act, designed to reduce and eliminate hazardous waste

Clean Air Act

Regulates air emissions from stationary and mobile sources to protect human health

Clean Water Act

protection of sea life and wildlife around the water by maintaining their environment

6 Criterion Air Pollutants

NO2, O3, SO2, CO, Pb, PM

Point Source Pollution

Pollution from an exact location/source

Non- Point Source Pollution

From an unknown/ un-exact source

Advantages and Disadvantages of Dams

Aquifer

Permeable layer of rock and sediment that contains groundwater

Unconfined Aquifer

Made of porous rock covered by soil, out of which water can easily flow

Ogallala Aquifer

Largest aquifer in the U.S. that has been overused for irrigation

Cone of Depression

An area lacking groundwater due to a rapid withdrawal by a well

Saltwater Intrusion

Infiltration of salt water in an area where groundwater pressure has been reduced from extensive drilling and pumping of wells

Turbidity

Murkiness of water

Love Canal

event which lead to the creation of the Superfund and CERCLA acts

Leachate

waste liquid that passes through landfills and picks up pollutants, considered hazardous waste

Leachate Collection System

Pipes inside a landfill that removes the leachate and carries it to the wastewater treatment plant

Monitoring Wells

Placed along perimeter of landfills to detect leaks of leachate and methane

Methane Collection Pipes

methane forms during anaerobic decomposition, it can be collected and used as fuel

Capping and Dry Tombing

Once a landfill is full and has reached the maximum permitted height, it’s covered with dirt and clay and then a plastic liner. This prevents any water from entering and becoming leachate.
