Opis

Covers contaminant hydrogeologic investigations. This book presents a practical approach to completing investigations for environmental compliance, emphasizing the use of geologic principles in assessment to move sites toward cleanup. It demonstrates how to solve a client's site contamination problem while maximizing cost effectiveness.

Recenzje

"The book takes you step-by-step through the investigation and includes client-consultant-regulator interaction, budgets, ethics, and data extrapolation for solving problems."-Environmental Geology
