For this episode we read: Geochemical Modeling of Water-Rock Interactions in Mining Environments (Alpers and Nordstrom, 1997).

For those who've asked "how do I become an environmental geochemist?" ...Tom has some advice for you. And for those that have questions about the business of consulting... his tea has some hard numbers. Best, though, is when we examine geochemical modeling philosophy and the Alpers and Nordstrom quote that models are "not reality, nor [are they] reliable, correct or valid representation[s] of reality."

After this show, I think we need to interview some more environmental geochemists!
