Regulations Regarding the Planning and Management of Residue Stockpiles and Residue Deposits from a Prospecting, Mining, Exploration or Production Operation were promulgated in 2015. These regulations require that residue stockpiles and residue deposits (e.g. tailings storage facilities, overburden dumps, discard dumps, stockpiles etc.) are characterized by a competent person in terms of chemical characteristics. Investigations are required to assess the potential for development of acid mine drainage and metal leaching from the residues. In addition, specialist geochemical investigations are often required as inputs into environmental impact assessments and water use license applications.

- Specialist geochemical investigation – Planning and initiating an investigation, including identifying appropriate rock types to sample, determining the analytical program, liaison with the laboratory, interpreting the data and preparing a report. Investigations can be limited to static (short-term) data or can be extended to include kinetic (long term) leach test data.
- Geochemical modelling – data collected during the geochemical investigation can be used to develop a model that can predict long term surface and groundwater quality related to mine infrastructure. Geochemical modelling data can be coupled with numerical hydrogeological models to model contamination plumes.
- Peer review of environmental geochemical models and reports.
