This three-hour online course provides general guidelines and techniques to manage surface water and gas emissions at uncontrolled hazardous and toxic waste (HTW) sites. Surface water management is necessary to reduce erosion and to control contaminant, leachate and gas migration. Management methods discussed include earth berms and levees, terraces and benches, disposal site surface grading and sealing, revegetation and passive and active gas control systems. Gravity systems including drainage ditches, seepage basins, sedimentation basins, flumes and combinations of these systems are discussed. The student will become familiar with methods and techniques used to manage surface drainage and leachate at hazardous and toxic waste (HTW) sites. The purpose is to reduce erosion, water ponding, runoff and infiltration of contaminated waste into downstream water or streams. The student will better understand the application of interception or diversion methods such as ditches, berms, flumes, terraces and benches and seepage and sedimentation basins. Other techniques for erosion protection, sealing and revegetation are discussed and describe chemical stabilizers, synthetic membranes, soil cement and asphalt concrete. The student will also become familiar with the gas generation and migration process and the basic components and construction considerations of various management systems. Also considered are the proper steps, materials and plants used to reestablish vegetation for erosion control and possible reuse of waste sites. Basic guidance in the selection of the most appropriate method to use and their advantages and disadvantages are discussed.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
