Nemko Norlab delivers customised outsourced laboratory solutions to a number of industrial companies.

Environmental analyses

Nemko Norlab has well-equipped laboratories and highly professional expertise in organic and inorganic analyses of municipal and industrial wastewater, leachate from landfills, contaminated soil, sludge, and sediments.

Wastewater

Wastewater includes industrial wastewater, municipal wastewater, oily wastewater, discharge water and grey water.

The standard parameters depend on the water region and recipient type, but generally include the following:

  • biochemical oxygen consumption (BOF5/BOF7)
  • chemical oxygen consumption (KOF-Cr)
  • total phosphorus
  • total nitrogen
  • suspended solids (SS)
  • pH
  • oil (mineral oil)
  • total organic carbon/dissolved organic carbon (TOC/DOS)

Analyses from industrial and municipal wastewater networks often require other analyses not mentioned above. Some of these can be delivered through our own laboratories while others are delivered through our partners.

 

Sludge

Sludge occur in various contexts,  in municipal wastewater systems, landfills, the aquaculture industry and more.

Typical issues:  Is it  hazardous waste, can it be used as  road fill, or if it can be used as  soil improvement (e.g. as organic fertilizer).
 

Typical analyses:

  • heavy metals, PAH16, PCB7, THC, BTEX in terms of hazardous waste
  • nutrient analysis (phosphorus, nitrogen, calcium, magnesium, pH, etc.) in addition to  heavy metals (for declaration as organic fertilizer).

Sediments

There are numerous of mandatory analyses required  with regards to fish farming, petroleum and industry, in addition to other activities that may pollute or contaminate the sea bottom, rivers and lakes.

Typical analyses:

  • MOM-C surveys:
    • copper, zinc, phosphorus, nitrogen, grading, dry matter, LOI (loss of ignition), TOC (incl. normalized TOC (Total Organic Carbon)) as minimum
  • for yards, tanneries, oil installations:
    • PCB7, PAH16, BTEX, THC, heavy metals, incl. chome-6

Other analyses depending on nature of activity.

We offer

  • accredited analyses.
  • assistance and advice in connection with sample collection.
  • extended reporting, including assessment of analysis results compared to regulatory limits.
  • sample bottles/bags in return packaging at no additional cost.
