K. Pantaleo provided the Committee with a presentation of the 2023 Annual Monitoring Report.
The Committe inquired why benzene, toluene, ethylbenzene and xylenes (BTEX) were being removed from monitoring. D. Kerr advised that it was a recommendation by the consulting firm completing the monitoring. This is due to the fact that the contaminant has not been a concern given the ability to divert materials that contain BTEX. These items are accepted at our household hazardous waste depot.
The Committee inquired about the mercury results within the report. D. Kerr explained that results are typically expressed and reported to a low value such as parts per million (ppm). This is a weight-to-weight ratio used to describe very low concentrations. Staff advised that specific questions about water quality results could be reviewed and discussed at a future meeting or on a one-on-one basis.
