Introduction
I am a contaminated land environmental scientist specialising in contaminated land management including legacy mine sites. I have been involved in acid and metalliferous drainage (AMD) in New Zealand and Australia. I am interested in sustainable management and remediation of sites.

Assessment of the potential for waste rock at coal mine sites to produce acid mine drainage is an important part of mine planning and operations and is commonly assessed using acid base accounting analyses. The underlying factor that controls mine drainage chemistry is the mineralogical composition of the coal measures sequences which in turn is co...

Coal mine drainage chemistry on the West Coast of the South Island is highly variable; pH ranges from about 2–8, and chemical concentrations vary by several orders of magnitude. Factors that influence mine drainage chemistry on the West Coast include regional geology, mine type, hydrogeology, and local geology. At a regional scale, mine drainage ch...

Dissolved As can be strongly adsorbed to fine grained Fe(III) minerals such as hydroxides, oxyhydroxides and hydroxysulphates. Therefore precipitates that form during neutralisation or treatment of acid mine drainage have potential to be useful for treatment of As-contaminated water because acid mine drainage is often Fe rich. We tested the adsorpt...

Backgrounds/aims: The purpose of this investigation was to determine liquidus compositions for ferromanganese slags. Methods: Measurements were carried out in a graphite resistance furnace at 1450 degrees C, 1500 degrees C and 1550 degrees C in an argon atmosphere. Molybdenum crucibles were charged with small amounts of slag. Samples were held at t...
