• Regulatory requirement• Documents the performance, operational effectiveness

and regulatory compliance of wastewater treatment plants (WWTPs)

• Assesses the environmental health of water bodies that are receiving liquid waste discharges from Metro Vancouver

• Provides information to the public

• Over 438 billion litres of wastewater treated in 2016

Metro Vancouver’s WWTPs

• About 51,400 samples collected• Over 195,000 analyses performed• About 54,200 tonnes of suspended

solids (TSS) and over 51,400 tonnesof biochemical oxygen demand (BOD) removed

• Treatment efficiency met or exceeded expectations and was consistent with previous years

• WWTPs consistently complied with the Operational Certificate requirements

• Non-compliance events were caused by extremely high flows through the plants during wet weather events or by BC Hydro power interruption

Effluent Toxicity Monitoring

• Characterization for all five WWTPs started in 2014• Included substances:

• Pharmaceuticals and personal care products (PPCPs)• Surfactants• Hormones and sterols• Polybrominated diphenyl ethers (PBDEs)• Polychlorinated biphenyls (PCBs)• Polyaromatic hydrocarbons (PAHs)• Phenolic compounds• Volatile organic compounds (VOCs)• Organochlorine pesticides (OCPs)

Endocrine Disrupting Substances and Trace Organics Monitoring

10

Beach Monitoring• Bacteriological water quality monitored at 41

beaches

• Bathing beaches met the primary-contact recreation guideline during the bathing beach season except for Wreck Beach Trail #7 (Oasis)

• False Creek, a non-bathing beach area, consistently met the applicable secondary-contact recreation guideline throughout the season

11

Receiving Environment Monitoring

• Comprehensive monitoring of environmental health of water, sediments and organisms in the vicinity of the WWTP outfalls

• Water quality objectives and guidelines for the receiving waters were largely met

• Monitoring results for sediment effects around two primary WWTP outfalls were similar to previous years

12

Ambient Environment Monitoring• 2016 ambient environment monitoring

programs:• Strait of Georgia (water)• Burrard Inlet (water)• Fraser River (water and sediments)• Boundary Bay (water and sediments)• Comprehensive program review

for Burrard Inlet

• Metro Vancouver WWTPs operate in compliance with the applicable regulatory requirements

• Metro Vancouver WWTPs continue to meet performance expectations and consistently provide an ongoing benefit to the region by reducing contaminant loading to the environment

• Various monitoring programs confirm that WWTPs are operating efficiently and with no adverse effect on human health and the environment

• Regional liquid waste discharges continue to be effectively managed in a manner that is protective of human and aquatic life
