The explosion killed 11 people, and spilled 4 million barrels of oil over an 87 day period. The explosion was caused by not enough cement being placed between production casings. 1.8 million gallons of dispersants and blooms were used to clean the oil. This spill lasted until September 19, 2010.]]> 2021-04-15 15:54:40 UTC https://padlet.com/ayu9767/ppz9anz3zpa7nq8n/wish/1421746865 ayu9767 https://padlet.com/ayu9767/ppz9anz3zpa7nq8n/wish/1421763115 Prince William Sound, Alaska suffered from an oil spill on March 24, 1989. The Exxon Valdez hit the Bligh Reef and tore open the hull, spilling 11 million gallons of crude oil. The spill covered 1,300 miles of coastline and killed hundreds of animals. To clean up the oil, workers skimmed, used chemical dispersants, and washed the beaches with hot water. Animals were rescued and cleaned.]]> 2021-04-15 15:57:41 UTC https://padlet.com/ayu9767/ppz9anz3zpa7nq8n/wish/1421763115 ayu9767 https://padlet.com/ayu9767/ppz9anz3zpa7nq8n/wish/1421776063 On August 1, 1953, in Camp Lejeune, the Marine Corps Base found two contaminated water supply systems. They found industrial solvents, trichloroethylene and perchloroethylene. This contamination increased the risk of leukemia and many organ cancers. The Navy disposed of all contaminated parts, and had clean water by December 31, 1987.]]> 2021-04-15 16:00:01 UTC https://padlet.com/ayu9767/ppz9anz3zpa7nq8n/wish/1421776063 ayu9767 https://padlet.com/ayu9767/ppz9anz3zpa7nq8n/wish/1421799147 Water began to leak into the mine tunnel causing toxic wastewater to enter the Animas River. In Silverton, Colorado, the river is still being cleaned. The water is so toxic, that nearby towns and cities are still regulating their drinking water as a precaution.]]> 2021-04-15 16:04:12 UTC https://padlet.com/ayu9767/ppz9anz3zpa7nq8n/wish/1421799147 ayu9767 https://padlet.com/ayu9767/ppz9anz3zpa7nq8n/wish/1421812736 An abandoned canal in New York was used as a chemical waste dump in 1978. It contained 21,000 tons of toxic chemicals and carcinogens. Contaminated groundwater was brought to the surface and nearby creeks were the dumping ground for sewers. Residents were evacuated at the time but there are no leftover threats after cleanup.]]> 2021-04-15 16:06:42 UTC https://padlet.com/ayu9767/ppz9anz3zpa7nq8n/wish/1421812736 ayu9767 https://padlet.com/ayu9767/ppz9anz3zpa7nq8n/wish/1421828151 The Pacific Gas and Electric Company dumped 370 million gallons of chromium-tained wastewater.

Oily waste and debris got stuck under wooden trestles and fueled the fire. Petroleum discharge ignited the fire. The fire lasted 20 minutes and reached 5 stories high before being contained. ]]> 2021-04-15 16:09:38 UTC https://padlet.com/ayu9767/ppz9anz3zpa7nq8n/wish/1421835098 ayu9767 https://padlet.com/ayu9767/ppz9anz3zpa7nq8n/wish/1421844315 During May of 1984, Woburn, Massachusetts was facing a drinking water shortage. Even though a study found contaminated groundwater in the area, two new wells were built. The groundwater was contaminated by leather curing compounds.
