The Testing Drivers

The South African regulatory framework.

  • · SANS 241 — drinking water quality, covering metals including lead, arsenic, mercury, cadmium, chromium, nickel, aluminium and manganese
  • · National Water Act & Water Use Licences — effluent discharge monitoring for mines, industrial plants and municipalities
  • · National Environmental Management Act & Waste Act — soil and groundwater monitoring at contaminated sites; mine closure and rehabilitation
  • · Acid mine drainage — a well-documented Witwatersrand burden requiring continuous water and soil monitoring
  • · Green Drop and Blue Drop assessments — Department of Water and Sanitation programmes scoring treatment works on compliance and process control
The PFAS Opportunity
40

PFAS compounds covered by EPA Method 1633/1633A across wastewater, surface water, groundwater, soil, biosolids, sediment, landfill leachate and tissue.

Regulatory limits are tightening globally, and South African commercial laboratories serving multinational clients and export supply chains are increasingly required to provide PFAS data. CEM's EDGE extraction system is specifically validated for the extraction step of EPA 1633/1633A — the clearest single new-revenue opportunity in this sector.

Standard Methods Used

USEPA 3051A (microwave acid digestion of sediments, sludges, soils, oils) · USEPA 3052 (with HF, for total decomposition of siliceous matrices) · USEPA 3015A (aqueous samples) · USEPA 3546 (microwave extraction of semivolatile organics) · USEPA 1633/1633A (PFAS) · USEPA 245.7 (mercury by CVAFS) · EN ISO 54321 (soil, biowaste, sludge, waste) · EN 13506 / EN 12338 (European mercury determination standards) · SANS 241 (South African drinking water quality).

Sample Types

Soil, sediment, sludge, surface water, groundwater, effluent, leachate, mine drainage, dust fallout, air particulate, plant and animal tissue, drinking water, biosolids.

The CEM method heritage. Many standard microwave-assisted methods used for environmental testing were developed on CEM instruments, because CEM systems were the reference platform when EPA and other official methods were being developed. A laboratory running EPA 3051A on a CEM system is running the method on the hardware it was written for.
