The report is designed to provide the Delaware General Assembly and the citizens of this State with an environmental profile that encompasses social, economic and environmental conditions in the City of Wilmington. CEEP received valuable assistance in preparing this report from many individuals in academia, state and local government. We owe our debt to Sally Wasileski, analytical chemist, and Terra Dassau, atmospheric chemist, both PhD. students at Purdue University Department of Chemistry. Their technical expertise of the properties and conversion equations of the chemical compounds discussed in this report was a critical component of our analysis. We would also like to show our gratitude to Marcos Luna of the University of Delaware for his GIS expertise. The staff of the Water Resources Agency has also contributed a great deal of GIS knowledge and technical information. We would like to specifically thank Gerald Kauffman, Vern Svatos, Martin Wollaston and Justin Bower for their tireless help. DNREC also supported our research efforts and assisted us in obtaining essential information. We would like to specifically show our gratitude to David Fees, William Fischer, Betsy Frey, Rick Greene, R. Peder Hansen, Karissa Hendershot, Paul J. Janiga, Lynn Krueger and Dennis Murphy.

We would also like to thank Tom Fikslin of the Delaware River Basin Commission and Bijaya Cherya of the City of Wilmington Water Quality Laboratory. I hope that this report will be useful in your discussions and deliberations on sustainability issues regarding our towns and neighborhoods. With knowledge of the environmental concerns faced by our communities and existing policy responses, the communities of our State can be leaders in building a livable future for Delaware.
