Soil testing


Contaminated Soil Testing

Testing for common soil contaminants in order to determine whether the soil should be classified as contaminated.

About this Testing

Soil may become contaminated with a wide variety of chemicals, e.g. hydrocarbons, heavy metals, and pesticides to name a few. Testing for different sites is governed by different guidelines, as detailed in the following table:

Contaminant Type

MfE Guideline

Petroleum Hydrocarbons

Guidelines for Assessing and Managing Petroleum Hydrocarbon Contaminated Sites in New Zealand

Gasworks

Guidelines for Assessing and Managing Contaminated Gasworks Sites in New Zealand

Timber Treatment

Health and Environmental Guidelines for Selected Timber Treatment Chemicals

Sheep Dip Sites

Identifying, Investigating and Managing Risks Associated with Former Sheep-dip Sites: A guide for local authorities

Not all contaminants have official guidelines, and even if there is, the use of the appropriate guideline is often dependant on the situation.

If the results are for your own interest and are not required by a legal entity or for legal purposes, the best course of action is to contact one of Hill Laboratories Client Service Managers for a quote. In order to set up a quote, you will need to have some idea of the likely contaminants to be found, so the more information you have on the site history, the better. Bear in mind that we do not collect samples either and can only provide limited advice on sampling and interpretation.

However, for all other purposes, it is best to use a consultant as sampling methodologies, interpretation of results and a detailed knowledge of remediation options require extensive training and experience.
