Whetstone Associates specializes in the design of geochemical testing programs for waste rock and soil characterization. We provide laboratory and consulting services for:

  • Sample selection and preparation (drying, crushing, pulverization, splitting, and compositing)
  • Geologic logging and sample description
  • Particle size determination
  • Quantitative determination of mineralogy and metal content (X-ray diffraction, X-ray fluorescence, scanning electron microscopy, transmitted and reflected light microscopy, inductively coupled plasma mass spectrometry/atomic emission spectroscopy)
  • Acid rock drainage and metal mobility studies (paste pH, acid base accounting and net acid generation testing, humidity cell testing, custom column and field-scale testing, Nevada meteoric water mobility testing, synthetic precipitation and toxicity characteristic leaching procedures)
  • Bottle roll and batch adsorption testing
  • Water quality and leachate analysis
  • Geochemical modeling
  • Source-term development for contaminant fate and transport models
  • Geochemical and water quality database development

We also provide secure long-term sample custody and storage for feasibility studies and permitting projects.
