The management of solid waste disposal is a high priority for councils and environmental engineers around the world.

Drawing on an unmatched portfolio of over 200,000 analytical methods, The Eurofins Food and Water Testing NZ network of laboratories in New Zealand is ideally placed to provide the analytical needs of landfill systems.

We offer a comprehensive range of surface, groundwater and leachate analyses, to assist councils with their legislative obligations around the planning and management of solid and liquid waste disposal, and the environmental monitoring of current and closed landfills.

Our testing capability includes:

  •          Full microbiological suite
  •          Low level metals analysis
  •          Low level nutrient analysis
  •          Full organic analyses

Landfill analyses are based on Ministry for the Environment criteria and can vary between locations. We operate a wide range of equipment and test methodologies capable of meeting all the required parameters.

Leaching Procedures

We provide leaching procedures to evaluate metal mobility. This includes the mixing of solid waste with the appropriate extraction fluid and tumbling for 18 hours in a rotary agitator. The liquid is filtered and then analysed for metals. Please refer to our metals brochure for more details.

Toxicity Characteristic Leaching Procedure

We offer the most commonly used EPA Method 1311,Toxicity Characteristic Leaching Procedure (TCLP) to evaluate metal mobility in a landfill. The extraction simulates a worst-case scenario where the waste is co-disposed with municipal solid waste.

Synthetic Precipitation Leaching Procedure

We use EPA Method 1312, the Synthetic Precipitation Leaching Procedure (SPLP) to evaluate the potential for leaching metals into ground and surface waters. This method provides a realistic assessment of metal mobility under actual field conditions, i.e. what happens when it rains (or snows). The extraction fluid is intended to simulate precipitation. The SPLP is a method of choice when evaluating fate and transport of metals in a properly engineered wasteland disposal facility from which municipal solid waste is excluded.
