Water Pollution
030 - Water Pollution
In this video Paul Andersen explains how water quality can be degraded by pollutants. Wastewater is the main source of water pollution and can be measure using the BOD (biochemical oxygen demand). Dead zones, cultural eutrophication, disease, and other pollutants are included. A basic description of sewage treatment, septic systems, and water purification is also included.
