=** Environmental Regulations: Hazardous Substances and Wastes **= =Kelcie Morris & Kyle Zollo= = = =//**What is hazardous waste?**//= ====Even when used properly, many chemicals can still harm human health and the environment. When these **hazardous substances** are thrown away, they become **hazardous waste**. Hazardous waste is most often a by-product of a manufacturing process - material left after products are made. Some hazardous wastes come from our homes: our garbage can include such hazardous wastes as old batteries, bug spray cans, and paint thinner. Regardless of the source, unless we dispose of hazardous waste properly, it can create health risks for people and damage the environment.==== = = =//**What kinds of hazardous waste are there?**//= = = = = = = =//**How can hazardous waste affect us?**//= = = = = = = = The Superfund Program = ====Years ago, before there were laws to control how hazardous chemicals were handled, many people disposed of hazardous waste by dumping it on the ground and in rivers or lakes, or burying it in the ground. The result? Eventually, thousands of hazardous waste sites were created at warehouses, harbors, manufacturing facilities, landfills, and many other kinds of places. In 1980 we began to get a handle on the problem, with the creation of the U.S. Environmental Protection Agency's (EPA) Superfund Program.====
