Evaluation of Health Risks from Consuming Vegetation Foraged
in Kelly Brook Wetlands in the Vicinity of the Beede Waste Oil NPL Site



  1. There was no non-cancer health threat was identified for individuals (children or adults) consuming marsh marigolds in the Kelley Brook wetlands.
  2. There is a very small increase in cancer risk to adults consuming six meals per year of marsh marigold at the maximum level of arsenic contamination over a lifetime.


  1. Individuals ingesting marsh marigolds should limit consumption of marsh marigolds to no more than 6 meals/year (one meal is approximately 86 grams or 3 oz.). Marsh marigolds should be thoroughly boiled or steamed before eating.

Further evaluation and recommendations will be made as additional data and information become available.
