Land Subsidence Mitigation
Aquifer Recharge Using Treated Wastewater Injection

This book examines the process of injecting treated wastewater into wells to replenish aquifers, and thereby slow the process of land subsidence, and help to mitigate coastal flooding. It explains how up to fifty percent of sea-level rise may be due to land subsidence, and up to fifty percent of land subsidence may be due to aquifer compaction. The concepts covered discuss replenishing aquifers with clean water to reduce nutrient discharges into out-falled waterways; providing a sustainable supply of groundwater; reducing the rate of land subsidence; and protecting the groundwater from saltwater intrusion. Practical case studies from Virginia and California will be included.

Frank R. Spellman, PhD, is a retired assistant professor of environmental health at Old Dominion University, Norfolk, Virginia, and the author of more than 110 books covering topics ranging from concentrated animal feeding operations (CAFOs) to all areas of environmental science and occupational health. Many of his texts are readily available online, and several have been adopted for classroom use at major universities throughout the United States, Canada, Europe, and Russia; two have been translated into Spanish for South American markets. Dr. Spellman has been cited in more than 850- publications. He serves as a professional expert witness for three law groups and as an incident/accident investigator for the U.S. Department of Justice and a northern Virginia law firm. In addition, he consults on homeland security vulnerability assessments for critical infrastructures including water/wastewater facilities nationwide and conducts pre-Occupational Safety and Health Administration (OSHA)/Environmental Protection Agency EPA audits throughout the country. Dr. Spellman receives frequent requests to co-author with well-recognized experts in several scientific fields; for example, he is a contributing author of the prestigious text The Engineering Handbook, 2nd ed. (CRC Press). Dr. Spellman lectures on sewage treatment, water treatment, biosolids and homeland security and lectures and safety topics throughout the country and teaches water/wastewater operator short courses at Virginia Tech (Blacksburg, Virginia). He holds a BA, in public administration, a BS in business management, an MBA, and an MS and PhD in environmental engineering.
