This is a notice of intent to award a sole-source, five-year contract to the Bad River Band for research support on a pilot study about cumulative environmental impacts on community health. The work will be performed for the Bad River Band and involves quantifying environmental exposures and assessing associated health outcomes using culturally relevant methodologies. The total estimated value of the contract is $1.1 million. The government justifies this non-competitive action due to the tribe's unique ownership of historic land data, specific expertise, and standing within the community. Responses to this notice must provide compelling evidence that competition would be advantageous and not hinder the project's objectives.
