Abstract

Approaches for the redevelopment of contaminated properties vary depending upon many factors including type/extent of contamination, risks, regulatory authorities and compliance, remediation cost, the resources/desires of the owners, compliance with Federal SEC reporting and the value/demand for the property. Reducing the remediation cost and cleanup time of groundwater are common objectives at many sites because groundwater remediation is typically the most expensive, time consuming and difficult media to cleanup. Innovative techniques to reduce groundwater remediation timeframes at the Universal City Property Management site in Florida USA include the following: Use of horizontal wells to effectively capture and recover groundwater. Use of chemical oxidation to rapidly cleanup the contaminated groundwater. Use of horizontal wells to distribute chemical oxidants. Creation and use of open pit excavation to directly expose and aerate the resulting groundwater in situ and remove contamination. Other approaches and elements that contributed to successful development of the site include: Flexible and dynamic remediation plans that respond to the owners need to sell or develop property to maintain a balanced cash flow. Effective and rapid remediation technologies (e.g., chemical oxidation) to facilitate property sale and development. Proactive coordination with regulatory agencies to build consensus and shorten review time of work plans and reports. Large area in a desirable location with great potential for development and revenue generation. All of these approaches and attributes of the site contributed to the successful remediation and redevelopment. Keywords: contaminated sites, cleanup, remediation, redevelopment.
