I heard some sad news a few days ago. Legendary hydrogeologist John D. Bredehoeft died on New Year's Day 2023. He was 89. He was a remarkable scientist, one who wanted to figure things out. Here is the citation written by Lenny Konikow, one of his mentees at the USGS, at John's reception of the Robert E. Horton award from AGU in 1997. The Groundwater Project wrote this tribute, that includes a recent picture and a brief list of publications.
I cannot top the accolades composed in his honor. In fact, I did not know John personally very well. Not so for his publications and interests - 'eclectic' is a word I would use to describe them. I also knew him from his close connection with my first employer, Burke Maxey, the renowned hydrogeologist at the Desert Research Institute in Reno, NV. John's PhD thesis at the University of Illinois dealt with the Humboldt River basin in Nevada.
My first meeting with John occurred in September 1974 at the GSA Penrose Conference in Aspen, CO. The theme of the conference was 'Mass and Energy Transport in Porous and Fractured Media' (John was one of the organizers) and it attracted big names - among them Shlomo Neuman, Paul Witherspoon, George Pinder (his PhD student). A certain number of grad students were invited and I was one of them. Talks were informal; my compartment model of the Edwards Aquifer was one of them. My University of Arizona PhD advisor, Dr. Gene Simpson, also attended.
Did John and I have a deep discussion on fluid flow through cavernous limestones? Well, not quite. After a few 'hellos' in the hall, we would end up at the same dinner table. There, John started talking about downhill skiing. I knew nothing about the topic. John kept talking about all the 'black diamond' runs at the Colorado resorts, I was smart enough to realize that those were the tough, expert-only trails. So I thought I would show my chops. I recalled my conversations with the golfers I had caddied for in the NH summers. The avid skiers among them had tackled the dangerous Tuckerman Ravine, a glacial cirque on the south side of Mt. Washington, the highest mountain in the Northeast. I dropped that into the conversation, stating that 'nothing in Colorado could touch that. Well, John shot me a look and the table went silent. He then proceeded to put me in my place vis-a-vis
Colorado ski runs.
But he did say my compartment model was 'interesting'.
That was my introduction to John.
Next stop: the early 1980s at DRI in Reno. I stumbled upon this publication:

This publication floored me. I had read Theis's 1940 paper and Richmond Brown's 1963 report. But this one had a real impact me. It made so much sense to me but I did not encounter many hydrogeologists or water managers who seemed to be aware of the implications. So I took it upon myself to photocopy about 10 copies and ship them to the Nevada State Engineer with a note describing its significance and closed it with: 'Make sure all your groundwater hydrologists read and understand this paper.' It was the 'and understand' that raised the hackles in Carson City. Suffice it to say that the DRI President read me the riot act but when I explained the paper, he understood. 'Next time, leave out those two offensive words.' I like to think that John would have been happy and would have said. 'You mean they hadn't read those publications? WTH?

Fast forward to the end of the century. John was working in private industry. I had been an officer in the Scientists and Engineers Division (S&E) of the National Ground Water Association (NGWA). Although the S&E were the most populous division the Contractors (well drillers and pump installers) ran the show. John got on the S&E Board and we welcomed him. The NGWA was agonizing over the fact that pumping wells could deplete streamflow and was looking for a reason to downplay that. John offered to write a letter to come from our S&E BoD. We thought that was great because we knew how thorough he would be. Well, after a few weeks we got John's 18-page single-spaced letter (with references) detailing the hazards of excessive pumping. He was not saying it should be banned but that it would have an effect. The letter worked and all was well with the NGWA leadership.
I might add that when John me met at the NGWA meeting he noted that I looked somewhat familiar. Where had we met? In Colorado, many years ago. He looked puzzled. Then he smiled and inquired 'When was the last time you skied Tuckerman Ravine?'. 'Quite a while ago,' I replied. 'You up for it?' was his rejoinder. We both smiled. 1974 seemed an eternity ago,
As I close this I am thinking of the seminal Rangely EQ experiments, contaminant transport modeling, deep fluid flow, California SGMA, GW budget myths, and so much more.
Yes, I hardly knew him, but boy, do I miss him! .
"These concepts must be kept in mind to manage groundwater resources adequately. Unfortunately, many of our legal institutions do not adequately account for them." -- J. D. Bredehoeft et al., 1982, p 57
