Groundwater Contamination Map, Toxic Plumes Map Source: The Chemical Legacy of Old Silicon Valley, NBC Bay Area, Map Editor Scott Pham 2019 The red dots represent Daycare centers from 2019. NBC Bay Area had a series of maps that indicated where the toxic waste sites were located and the extent of the damage encompassing vast areas of the community but they took it down. The pollution is in the groundwater so it covers a vast area in Pink.
