Waste disposal is a process with important environmental implications. Proper management is essential to protect both human and environmental health. Most of our solid waste ends up buried in landfill sites. While it decays in landfills it can generate methane gas. It is explosive, can catch on fire and, to make matters worse, contributes to the greenhouse effect. Incinerating waste is also problematic, as gases from incineration may cause air pollution and contribute to acid rain.
Water waste and liquid waste get funneled into our nations sewage systems, where they go to the municipal treatment plants. The process at the plants involve several methods and which include both physical filtering, as well as chemical and biological treatments. This process is intended protect human health, as well as the health of our groundwater aquifers, rivers, lakes, estuaries, and oceans. However problems occur when raw sewage leaks into the environment, often a result of aging or damaged sewer lines. Our nations water treatment infrastructure is aging and in need of modernization.
Waste is classified by source and composition. Broadly speaking, waste materials are either liquid or solid in form, and their components may be either hazardous or inert in their effects on health and the environment.
