MD&E was hired by a Midwestern electrical utility to develop and manage a strategy to address aquatic toxicity issues associated with a former coal-fired power plant property on the banks of downtown river frontage. Re-development of the property and former plant structures as a corporate headquarters and public river walk was contingent upon successful resolution of these issues. MD&E recognized deficiencies in previous toxicity evaluation efforts and re-interpreted the geochemistry of site soils and groundwater to establish the basis for closing the site as a hazardous waste facility. As a consequence, the utility was able to avoid costly and unsightly active remediation measures. The former power plant property has now been fully re-developed and contributes significantly to the revitalization of the municipality.
