    Fundamentals of Groundwater Quality and Hydrochemistry using AQUACHEM

    Provides an overview of natural groundwater and surface water quality, fundamentals of geochemistry processes and quantification (water-rock interaction, natural aqueous facies and evolution along groundwater flow), common graphing and interpretation techniques, as well as basic geochemical modeling using Aquachem and Phreeqc (USGS reactive models)

    Day 1

    Aqueous Geochemistry fundamentals

    1. Fundamental concepts: units, solutes, alkalinity/pH, Redox, Groundwater types
    2. Water Rock interaction processes: Mineral precipitation and dissolution, gas dissolution, Redox processes, ion exchange, Mineral equilibrium, reaction rates
    3. Water quality:
      1. Definition of water quality
      2. Drinking water standards
      3. Sources of contamination
    4. Use of isotopes in the study of groundwater geochemistry
    Day 2

    Data collection, management and analysis

    1. Groundwater sample collection: field and lab QAQC techniques
    2. Data display (plots): Piper, Schoeller, Box & Whiskers, time series and other diagrams
