APES Waste Management

List the current criteria required by the government for landfills.

1. Cannot pollute surface or groundwater. 2. Compacted clay and plastic sheets. (prevents liquid waste from seeping into groundwater) 3.Double liner system, (plastic, clay, plastic). 4. System to collect leachate (liquid that seeps through the soil waste)

1. On-site disposal: 2. Composting: 3. Incineration 4. Open dumps

1. Disposing of waste at the site that the waste is produced. 2. Letting organic waste decompose under controlled conditions. 3. Burning waste to reduce its volume and sometimes to produce electricity. 4. Typically found in developing countries. Fields or holes in the ground where waste is deposited and that sometimes gets covered with soil.

1. Sanitary landfill 2. Leachate

1. Landfill that lines the bottom with plastic and clay with a collection system. 2. The water that leaches through the solid waste and removes various chemical compounds with which it comes into contact.

A method of developing as many ways as possible to reduce waste and environmental harm. This method uses reducing, reusing, and recycling before landfills and incineration.

What environmental and human health risks are associated with landfills?

Contamination of groundwater through leachate, possible emission of various dioxide, and other various volatile organic compounds into the atmosphere, possible movement of these gases underground.

What are hazardous wastes? How extensive is the problem of uncontrolled hazardous waste disposal?

Through leachate or gas emission.

What are some of the alternatives to land disposal of hazardous wastes?
