.--This paper contains concepts and examples of how geochemistry can be used to interpret chemical analysis from monitoring wells, soil leachates, and overburden to predict the water quality resulting from mining and reclamation activities. The processes involving the major chemistry are described by thermodynamic models calibrated to the steady-state conditions of the undisturbed groundwater/soil system. The behavior of trace metals are interpreted as a function of the major chemistry.

Two critical decisions were made in the design of Canada's first fully online doctoral program discussed in this chapter: to create a professional Doctorate in Education rather than a PhD and to enroll students as cohorts each year. The first decision was based on the contemporary need within the field of online higher education for discipline specialists to have a solid background in online education principles and practice. The second decision was made on the basis of literature around benefits for graduate students. However, little sustained research has been carried out on what specific benefits may accrue for doctoral students participating in a cohort-based program in an online environment. This chapter presents and discusses the outcomes of two research studies on a cohort model, to provide insights into some of the personal and other factors identified as early warning indicators of student difficulties and how and when they arise.
