This was  \nmostly due to rapid population growth and increased industrial activities, which used the river as an open sewer and dumping ground. Severe pollution was most evident by the prevalence of waterborne illnesses and in the sharp decline of migratory fish populations, such as the American shad and Atlantic sturgeon. Parts of the estuary were considered dead zones, almost or completely devoid of oxygen needed for the survival of aquatic life.  \nWhat Was Done?  \nThe 1937 Philadelphia Record editorial page cartoon depicts the time when the tidal Delaware was an open sewer, where pollution in some stretches robbed the river of all its oxygen needed to support fish and other aquatic life.  \nIn the late 1930s, these problematic conditions prompted the formation of the Interstate Commission on the Delaware River Basin, or INCODEL, by Delaware, New Jersey, New York and Pennsylvania. Cleaning up the severe water pollution in the Delaware Estuary was at the top of this advisory commission’s priorities. The first set of interstate water quality standards was adopted through INCODEL, initiating the creation of new sewage treatment plants and also the completion of dredging the Schuylkill River and Delaware Estuary of coal silt, which was one of the nation’s first non-point source pollution control programs.  \nBuilding on the experiences of INCODEL, the Delaware River Basin Commission (DRBC or Commission) was established in October 1961 when the Delaware River Basin Compact became law. The Commission was formed well before the 1970 creation of the Environmental Protection Agency, the 1972 passage of the federal law commonly known as the Clean Water Act, and the formation of many state environmental agencies. Like INCODEL, the Commission ’s members are the four Basin states (Delaware, New Jerse","cbCaiqIwv98PyBba","https://ap.wps.com/l/cbCaiqIwv98PyBba","pdf",2339121,"English","# Introduction\n## A Historical Perspective\n## What Was Done?","[{\"question\":\"What were the main causes of severe pollution in the Delaware River according to the document?\",\"answer\":\"Pollution in the tidal reaches was driven by rapid population growth and increased industrial activities that used the river as an open sewer and dumping ground.\"},{\"question\":\"How did INCODEL contribute to early water quality improvements?\",\"answer\":\"In the late 1930s, INCODEL was formed to prioritize cleaning up severe water pollution in the Delaware Estuary and to adopt the first set of interstate water quality standards.\"},{\"question\":\"When and how was the Delaware River Basin Commission (DRBC) established?\",\"answer\":\"The DRBC was established in October 1961 after the Delaware River Basin Compact became law, creating a regional body with legal authority and including both basin states and a federal representative.\"}]","Water Quality Programs of the Delaware River Basin Commission - Introduction - A Historical Perspective - What Was Done? | PDF",1791857472]
