The Federal Environmental Quality Guideline in surface water for Bisphenol A is 3 500 nanograms per litre (ng/L). Samples with BPA concentrations above the guidelines are defined as an exceedance. See the drainage region map (www.canada.ca/en/environment-climate-change/services/environmental-indicators/bisphenol-A-water-sediment.html#map). Measurements were made in 1 931 surface water samples collected in 51 sites from 10 drainage regions between 2008 and 2018.,,,,, Source: Environment and Climate Change Canada (2019) Chemicals Management Plan Monitoring and Surveillance (www.canada.ca/en/health-canada/services/chemical-substances/chemicals-management-plan/monitoring-surveillance.html).,,,,, Available on the Environmental indicators website (www.canada.ca/environmental-indicators).,,,,,
