Solids & Biosolids

What do I test my biosolids for?

The current guidelines for testing and application can be found here. 

Further guidelines are being developed and will cover additional organic material. Click here for more information.

Who can assist me with interpreting my soil results?

While we specialize in soil testing, we do not provide consulting services. Please contact a consultant if you require help interpreting your test results.

Where can I find the landfill acceptance criteria?

In the first instance, it is best to contact the landfill you are hoping to use as they may be able to provide you with their requirements. Alternatively, The Ministry for the Environment provides a guideline for landfill classification and acceptance criteria. Click here for more information.
