EPA Model Fixes Could Help Set Lead Cleanup Limits For Strict New Goals

摘要

EPA's waste office is planning to revise its model for estimating lead exposures at contaminated waste sites, changes that could help the agency set soil cleanup levels should the agency decide to strengthen its risk reduction goal for the metal at Superfund and other hazardous waste sites. The model changes could revive long-standing industry concerns that the model overestimates exposures and results in overly stringent cleanups, especially if the agency decides to adopt the significantly stricter risk reduction goals that several other agency programs have already adopted or are considering adopting.
