Contamination Guidelines set a maximum amount of heavy metal or mineral allowed in the SOIL - expressed as mg/kg
Soil contamination Guidelines or Health investigation Levels (HILs), are available for Residential A, Residential B, Recreational use and Industry & Commerce. The guideline levels, however are different for the different intended LAND usage. See the Guidelines page for more details

There are links within your results that take you to further information. This information is being updated regularly.

Additional information includes your actual result expressed as mg of the metal per kg of soil, the guideline upper value used to visualise the result, the date and lab job number and client sample details. LOD stands for "Limit of Detection"
Very toxic metals like Lead, Cadmium, Arsenic and Mercury, don't want to be even near 100% of the allowed guideline.
It is paramount to find the source of the heavy metal contamination. Don't let children play around or in suspect soils.
