Table of contents
Chapter 1 Introduction
What is ASR? historical development in several countries; ASR applications;
objectives of the book.
Chapter 2 ASR Program Development
Phase 1, Feasibility Assessment and Conceptual Design, including discussion
of recharge objectives, water supply variability, hydrogeology and other key
elements of a complete feasibility analysis; Phase 2, Field Test Program,
including baseline testing, development of target storage volume, cycle
testing, data collection, sampling frequency, test program duration; Phase
3, ASR Wellfield Expansion, including flow rate balancing, well spacing and
arrangement, stacking, wellfield layout; Operations and Maintenance; and
Water Supply Planning with ASR.
Chapter 3 Design of ASR Systems
Detailed and comprehensive information regarding the design of ASR wells,
wellheads and wellfields, considering different materials of construction;
drilling methods; corrosion control; yield strengths; casing collapse
pressures; initial and lifetime costs; cementing; mechanical integrity
testing; selection of storage intervals; screen design; well development;
directionally-drilled ASR wells; pipeline flushing and waste discharge;
trickle flows; sampling taps; disinfection; downhole flow control; air and
vacuum relief; pressure, water level and flow measurement; disinfection and
pH adjustment; pump and pump column, well site considerations; energy
recovery; dispersive and advective mixing at ASR wellfields; alternative
wellfield design considerations and stacking of ASR wells.
Chapter 4 Selected Technical ASR Issues
Recovery efficiency; water quality improvement with successive cycles; water
quality during the initial ASR cycle; target storage volume; well plugging
and redevelopment; wellhead filtration; disinfection byproduct reduction;
fate of microbiota during ASR storage; arsenic attenuation during ASR
storage; pre- and post-treatment for several constituents; simulation
modeling, water supply model, wellfield operations model, solute transport
models; effective hydraulic area; well rehabilitation.
Chapter 5 Geochemistry
Water chemistry parameters; mass balance; water chemistry diagrams;
hydrogeochemical processes; changes in groundwater chemistry with depth;
Eh-pH diagrams; aquifer characteristics; geochemical analyses of cores;
geochemical processes; kinetics; geochemical models; laboratory and batch
testing; field investigations.
Chapter 6 Selected Non-Technical ASR Issues
Economics; water rate impacts; legal and regulatory issues; permit process
for ASR; statutes and rules; groundwater protection and the EPA Underground
Injection Control Program; non-degradation of groundwater quality; other
drinking water protection rules; water rights, water use restrictions, and
aquifer management regulations; ownership and use of the stored water;
seasonal vs. long-term storage and recovery percentages; water level
impacts; location for recovery of stored water; suggested ASR regulatory
framework; environmental impacts; public involvement.
Chapter 7 Alternative ASR Applications
Technical, regulatory and economic aspects of storing high quality surface
water, untreated and partially-treated groundwater; riverbank filtration
pretreatment for ASR storage; reclaimed water storage; suggested reclaimed
water ASR regulatory strategy; desalination and ASR; aquifer thermal energy
storage (ATES).
Chapter 8 Selected Case Studies
10-year update of 17 case studies from the first edition, plus two new case
studies from Australia and Namibia.
Chapter 9 Future Directions
Water philosophy; microbiology and geochemistry; ASR well and wellhead
design; bank filtration; ecosystem enhancement; storage in fractured hard
rock aquifers; economics; groundwater zoning; target storage volume;
regulatory and water management framework; growth management; global
applications of ASR.
