Posted By MAK Depends on what you are doing with the soil? How much of the soil is affected? are you digging it up, disturbing it or is there is any risk of arsenic entering water systems.

Posted By MAK sorry to state the obvious, but you have to assess the risk. going on what you describe only, the risk of direct exposure is low, the quantity in the soil has been described as low risk. As long as it is not ingested the risk should be low. Note though inorganic arsenic can be inhaled also. does your report state what kind or the likley source? some control measures: clearly section off the affected area and make it a no-go. hopefully the owner of the land has been informed? PPE as a last resort measure and a good hygiene regime will reduce the risk further. note smokers are already exposed to arsenic through the habit so they will be slightly more at risk. (arsenic occurs in nature, i.e shellfish, coal, grains, meat and is usually present in soils in a low amount).
