Contamination Guidelines set a maximum amount of heavy metal or mineral allowed in the water - expressed as mg/L
Water contamination Guidelines are available for Drinking Water, Irrigation Water and water used for Livestock. The guideline levels, however are different for the different intended water uses.
Clicking on the different guideline buttons shows the same result but visualised with the different guideline upper value
There are links within your results that take you to further information. This information is being updated regularly.
All links are in blue. Metal name links take you to the substance profile on Toxno.
Additional information includes your actual result expressed as mg of the metal per litre of water, 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, Mercury and even Copper, don't want to be even near 100% of the allowed guideline.
It is paramount to find the source of the heavy metal contamination and if contamination exists, best to stop using the water in the interim.
