Remedial systems designed to restore contaminated environments to beneficial use are increasingly required to address multiple objectives. Engineered remedies must decontaminate or contain pollutants in complex media while minimizing factors such as cleanup time, cost and energy inputs, and secondary waste generation. Remedial designs are often constrained by surrounding property use, adjacent contamination, sensitive habitats, and/or regulatory requirements. While environmental simulation models can support remedial design, models alone cannot identify an optimal solution that balances multiple objectives, design options, and constraints.
To address these deficiencies, HGL has developed PBMO™ to link environmental modeling with management optimization. The PBMO™ tool identifies optimal remedial design and operational approaches that lead to timely and cost-effective cleanups. By linking modeling and computational optimization, PBMO™ can realistically capture important site physics and financial constraints; achieve a coherent interpretation of disparate site data using all relevant information; and produce structured, credible solutions acceptable to stakeholders and regulators.
