Description

Anthropogenic activities have caused water contamination and degraded water quality in rivers. Combined sewer overflows (CSOs) discharge untreated sewage mixed with rainwater into the river directly during or following rainfall, elevated levels nutrients (phosphorus, nitrogen, ammonia), bacteria (fecal coliform, E.Coli., enterococcus), as well as high molecular weight polychlorinated biphenyls (PCB 11). CSOs, stormwater runoff and effluents from wastewater treatment plant are the primary sources of contamination in rivers and estuaries. Heavy metals (arsenic, lead, mercury, cadmium), PCBs, polycyclic aromatic hydrocarbons (PAH), dioxin, pesticides, persistent organic pollutants (POPs, includes chlordane and DDT before they were banned in US), as well as other inorganic/organic pollutants have been discharged into the river, caused water contamination and degraded water quality, threatening fish consumption safety and public health. Any topics relates to water contamination, water quality improvement, making river fishable and swimmable; environmental ecosystem restoration; fish consumption safety; land use impact are welcome to this session.
