This book is a valuable guide for engineering professionals involved with the day-to-day management of petroleum and other industry operations. The expert authors develop the concept of limiting constitutes, spill remediation, and waste disposal on site. The book is a how-to compendium for engineers involved in the remediation of 'Non-Hazardous' (i.e., non-nuclear) impacted waste and/or soil. This book contains techniques, data and recommendations for 'how clean is clean'. The book is the result of 10 years of research and experience in the clean-up of oil and gas field non-hazardous waste (NOW).
