D Correct answer
Explanation

Landfills are the primary method for solid waste management in the United States. While recycling is encouraged, it does not account for the majority of total waste disposal compared to burial.

Multiple choice

The __ allows for owners who illegally dump waste to be sued and pay fines

  1. Landfill Act

  2. Hazardous waste Act

  3. Superfund Act

  4. The Recourse Conservation and recovery act

C Correct answer
Explanation

The Comprehensive Environmental Response, Compensation, and Liability Act, commonly known as the Superfund Act, allows the government to hold parties accountable for hazardous waste dumping and fund cleanup efforts.

Multiple choice

A material is biodegradable if

  1. it is made of synthetic material

  2. it is made from petroleum or natural gas

  3. it can be broken down by biological processes

  4. it can be disposed of in a landfill
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Biodegradability is defined by the ability of a substance to be decomposed by biological processes, such as the action of microorganisms.

Multiple choice

Which of the following are problems associated with landfills

  1. source reduction and composting

  2. leachate and methane production

  3. surface impoundment and leachate

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Leachate is a toxic liquid that forms when water filters through waste, and methane is a byproduct of anaerobic decomposition, both of which are major landfill issues.

Multiple choice

Which of the following is Not a requirement of a landfill built today

  1. it must be lined with plastic or clay

  2. it must be a specific distance from a city or populated area

  3. it must have systems for collecting and treating leachate

  4. Vent pipes must be installed for removing methane.

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

While landfills have strict environmental regulations, there is no federal requirement that they be a specific distance from a city, though zoning laws often dictate this locally.

Multiple choice

a common characteristic of all hazardous waste land disposal sites is they

  1. are long-term storage sites

  2. make use of deep-well injection

  3. pose no threat to the environment

  4. are not regulated by state or federal laws
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Hazardous waste land disposal sites are designed as long-term storage facilities intended to isolate hazardous materials from the environment indefinitely.

Multiple choice

the main problem with so called biodegradable plastic is that

  1. only its organic portion actually decomposes

  2. animals often choke on the plastic litter that forms

  3. it releases toxic compounds as it breaks down

  4. it included a chemical made by a rare bacterium
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Many 'biodegradable' plastics are blends of plastic and organic materials; only the organic portion breaks down, leaving behind microplastics.

Multiple choice

The process of composting

  1. uses synthetic materials

  2. has little potential to conserve landfill space

  3. is always carried out in city run facilities

  4. could effectively handle a variety of waste
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Composting can handle a wide variety of organic waste, including food scraps and yard waste, which diverts significant volume from landfills.

Multiple choice

The methane found in landfills is a gas that

  1. is produced when wastes react with oxygen

  2. must be pumped to the surface in leachate pipes

  3. is a major contaminant of ground water

  4. may be captured and used to produce energy
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Methane is a combustible gas that can be captured from landfills and used as a fuel source for energy production.
