People Investigating Toxic Sites was founded in 1984 to provide information on locations and dangers of open and closed dumpsites (landfills), contaminated groundwater, and to investigate illnesses related to contamination of the environment.

Most dumpsites contain carcinogenic chemicals and highly flammable, highly explosive methane gas.   Health studies show connections between exposure to chemicals in dumpsites and cancer, leukemia, autism, birth defects and other serious illnesses.
