EVSC 220 Lecture Notes - Lecture 10: Point Source Pollution, Activated Carbon, Sorption
Document Summary
Any chemical or material out of place, or present at higher than normal concentrations. Nutrients, acidity, salinity, and solidity, sediments or particulates, ghg, pesticides. Decommissioning: clean up of a size or portion thereof, or clean up the site to where no more harmful activity will be done. Reclamation: activities carries out to obtain appropriate provincial certi cation that site is restored. Restoration: returning a site to native condition. Most mine tailing in sk treated by contaminated: contouring, planting. Environmental assessments done before activity planning process. Environmental site assessments (esa) done after: to assess the damage. More aggressive remediation associated with point source pollution. Mine spoils, chemical soils, industrial contamination, land conversion. Point source methods that are di cult but easier to remediate compared to non point source. Adsorption: physical sorption or trapping of contaminated on activated charcoal or synthetic resins. Absorption: when it is taking in uid and it absorbed by an object.
