Document Summary
Identify contaminants and their characteristics of transport behavior. Identify the characteristics of aquifer geology (factors controlling gw flow- physical dimensions, structure) Determine the hydrologic characteristics of polluted aquifer- flow direction, flow rates, discharge and recharge conditions. Methods of treating groundwater and vadose zone water (table 13. 5) Extraction wells-> pumps out contaminated water, and treated by filtration. Vapor extraction-> uses vapor extraction well and then treatment. Bioremediation-> injection of nutrients and oxygen to encourage growth of organisms to degrade contaminants. Including reduction, recycling, reuse, composting, landfill, and incineration. Three rs approach (reduce, reuse, recycle): reducing urban refuse by 50% More notable, success with recycling, but less successful with reducing waste production. Combining sustainable use of materials with resources conservation. Industrial ecosystem: producing natural urban and industrial ecosystem through material management, waste from one part of the system as a resource for another part. Sewage (wastewater + contained solid waste) constitutes the largest volume of liquid waste.
