Waterlab (Pty) Ltd provides the following services for Solid Waste, Rock, Soil, Sludge and Mine tailings:

 

Geochemical Characterisation

Waste Classification

Contaminated Land

Sludge Classification

Corrosivity

Customised experiments

 

1. Geochemical characterisation analysis includes:

  • Static Testing on rock-, tailings- and soil samples. Major cations, anions and trace elements are determined in rock or soil samples after liquid extractions are performed.
  • Extractions on solids include Distilled Water, Acid Rain, TCLP, SPLP, H2SO4 and Peroxide
  • Total metals in solids are determined after microwave digestion by acids by either ICP-OES or ICP-MS.
  • Other rock characterisation analyses include
  • Acid Base Accounting (ABA),
  • Nett Acid Generation (NAG),
  • Sulphur Speciation,
  • Total, Organic and Inorganic Carbon
  • XRF and
  • XRD
  • Kinetic Testing
  • Humidity Cells
  • Column Leach Tests

 

2. Waste classification according to the National norms and Standards for the Assessment of Waste for Landfill Disposal:

  • Leachable Concentrations using the Australian Standard Leaching Procedure (AS4439.3) using Acetic Acid solution (TCLP), Sodium TetraborateDecahydrate solution (Borax) or Reagent Water (Distilled Water)
  • Total Concentrations
  • Microwave Acid Digestion for metals
  • Total Fluoride and Hexavalent Chromium
  • Total Cyanide

 

3. Contaminated Land according to the National Norms and Standards for the Remediation of Contaminated Land and Soil Quality:

  • Total Concentrations for metals by Microwave Acid Digestion for Soil Screening Values (SSV)
  • Organics
  • Total Cyanide
  • Total Anions

 

4. Sludge Classification according to the Guidelines for the Utilisation and Disposal of Wastewater Sludge for:

  • Total Concentrations by Microwave Acid Digestion for Compulsory and Recommended metals
  • Total Phosphate and Total Kjeldahl Nitrogen
  • Total Solids and Volatile Solids
  • Volatile Fatty Acids on sludge with 50% water
  • Poly Aromatic Hydrocarbons
  • Faecal Coliforms and Helminth Ova

 

5. Corrosivity towards concrete or metals:

  • Basson Index  - Concrete
  • BRE – Concrete in aggressive ground
  • DIN -  50 929 Part 3 Metals

 

6. Customised experiments according to client specifications.
