Landfills are a great example of "Out of sight - out of mind" Once the final cover od soil and grass is in place the potential problems are ignored.

Wastes in a landfill can be broken down into several categories: * Inert * Toxic * Biodegradable * Soluble (leachable)

A properly designed waste disposal site is contained by liners and clay covers so that nothing gets in or out. A poorly designed system is more like a teabag.

So what comes and goes through a poorly designed site?

Water comes through from the surface. This speeds up decomposition and brings in oxygen to promote the growth of microorganisms.

The decomposing organics liberate methane gas (a powerful greenhouse gas). The gas flows out of the surface of the site to the atmosphere or travels with pores in the soil to local basements causing safety problems.

As the water seeps through the mass of waste it dissolves organics, salts and metals from the site. These flow down and into the groundwater where they degrade the potability and usefulness of the water in several ways. If the water flows out into a stream it can kill fish or eutrophy the water to promote algae growth

Landfills pollute groundwater, because the waste seeps into the soil and then pollutes the water, if not professionally designed and frequently topped by bulldozing a soil layer on top.

What caused new legislation to be passed in New Jersey in 1973?

In 1973 the new jersey legislature passed laws prohibiting the importation of solid or liquid waste that originated or was collected outside the territorial limits of the state. Operators of private landfills and several cities in other states with whom the collectors had contacts for waste disposal brought suit, attacking the new jersey law as unconstitutional.

How are civil rights and civil liberties different?

My answer is that you can do anything as long as it doesn't hurt anyone on a large scale. I say "on a large scale" because it is almost impossible to do anything without hurting someone else. When we drive to work we hurt people. First of all we pollute the air for people that have asthma. We also worsen the plight of ulcer patients that get nervous in traffic and thus produce more acid in their stomachs. We also put pets in danger. Many cats and dogs, probably in the the tens of millions, are killed by cars. The question is, does the benefit outweigh the negative effects? Yes, because without the vehicle our life expectancies would go down, and I don't have the time to go into why this would happen (might have something to do with not being able to get food into the cities in time for the masses to eat it.) Because marijuana is the big issue right now I will discuss this. Smoke, smoke, your hearts content. The marijuana issue is one of the biggest debates right now because people have begun to think. And where does the rabbit hole of thinking lead us to? It leads to a very normal man or women sitting at home smoking a bowl, while the drunks are downtown picking fights at the bars and killing people in car wrecks on the way home. These same people are driving up health costs by their health problems that they will inevitibly incur. Meanwhile, the pot smoker sits at home, laughing and talking with friends, too relaxed to fight and too mellow to look for his car keys. In all my years of life I have still not seen two pot smokers fighting and also very few auto accidents. And these are usually fender benders cause pot-smokers usually drive well under the speed limit, which is more than I can say for drinkers. I know why the government doesn't want pot-smokers. Cause it makes you think. The spectrum of truth and lies is placed before your intelligence. You are able to make decisions based on love and fairnes. But we don't want that in America. It was tried before and the system began to unravel. Where marijuana is, organized religion breaks down, and the unfairness of governments is exposed, something the Indains know about. We don't want that in the USA.

Why must landfills be replaced far away from groundwater sources?

Landfills must be located far away from groundwater sources to prevent contamination of the water supply. Leachate, a liquid byproduct of decomposing waste in landfills, can contain harmful chemicals that can seep into the groundwater and pollute it. Placing landfills away from groundwater sources helps protect the quality of drinking water and the environment.

What is groundwater and why is groundwater pollution the most likely environmental danger of landfills?

Groundwater is water that is stored beneath the earth's surface in soil and rock formations. Groundwater pollution from landfills occurs when chemicals and toxins from the waste leak into the groundwater, contaminating it and posing risks to human health and the environment. This is a common environmental danger of landfills because the liner systems meant to prevent leakage can degrade over time, allowing pollutants to seep into the groundwater.

What happens when poisonous chemicals accumaate in landfills?

When poisonous chemicals accumulate in landfills, they have the potential to leach into the soil and groundwater, contaminating the surrounding environment.
