The Silicon Valley Toxics Coalition (SVTC) works "to document and expose the hazards of the high-tech industry and to promote environmental and economic sustainability and accountability in the electronics industry, the fastest growing manufacturing sector in the world." To those ends, the SVTC Website offers three interactive Eco Maps showing Toxic Chemical Point Sources, Cumulative Exposure (including demographics and cancer risk), and Contaminated Groundwater Sites in the San Jose, California area. Pollution sources are identified by name and year, with an internal reference code. Helpful instructions accompany all maps.
