can highly recommend the one book written on the subject of ASR. It is very well-written and has lots of pictures, even one in color. Christmas is coming up (sooner or later) and the book makes a great stocking stuffer, so order lots of copies.The book is: Pyne, R. D. G., Groundwater Recharge and Wells: A Guide to Aquifer Storage Recovery. Lewis Publishers, 1995. It has 376 pages. You can order a copy from CRC Press and from other sources.

he American Water Works Research Foundation (AWWARF) published "Aquifer Storage Recovery of Treated Drinking Water" in 1996. This is an excellent presentation of the subject, focusing on the issue of the fate of disinfection byproducts during storage in ASR wells. Co-authors are me, Dr. Philip C. Singer and Dr. Cass T. Miller at the University of N. Carolina.

our international symposia on artificial recharge have been conducted. These were in Anaheim, California (1989); Orlando, Florida (1994), Amsterdam, Holland (1999), and Adelaide, Australia (2003). Proceedings for these excellent symposia are available for purchase, and contain several papers on ASR. ASCE has published Guidelines for Artificial Recharge, which should be a valuable document for those contemplating initiating such programs, whether with surface recharge or wells.

The Fifth International Symposium on Management of Aquifer Recharge (ISMAR 5) will be held in Berlin, Germany, June 12-17, 2005. Register online at www.ismar2005.org.

The American Ground Water Trust is sponsoring its fourth Aquifer Storage Recovery program in Tampa, Florida, April 15-16, 2004. Register online at http://www.agwt.org/events/tampa04_info.htm

CSIRO in Adelaide, Australia, conducted the first international symposium on ASR, about 1998. Proceedings may still be available. A second such meeting was held in 1999.

he American Water Resources Association (AWRA) conducted an ASR symposium in Long Beach, California, during 1998. This included many excellent papers. Copies of the Proceedings should still be available.

robably several hundred papers on the subject of ASR have now been presented in various other meetings, seminars and symposia during the last few years.

If you know of other documents that constitute a valuable resource for this subject, please contact David Pyne and I will add the information to the list.
