title: Usefulness of comprehensive feasibility studies in environmental epidemiology investigations: a case study in Minnesota.
abstract: Episodes of public water supply contamination with industrial or agricultural chemicals frequently give rise to public concerns about adverse health effects. These concerns may precipitate epidemiologic or clinical investigations requiring large expenditures of state and federal resources regardless of whether such investigations are justified by scientific criteria. An alternative is a comprehensive feasibility study, utilizing all available information to determine whether large-scale studies are warranted or feasible. At a relatively modest cost, a feasibility study allows health officials to identify information needs and deficiencies, outline potential study options and costs, clearly establish the rationale for a proposed study or, conversely, prevent unwarranted expenditures of public resources. Furthermore, a feasibility study may in itself resolve many community and scientific concerns. This article provides a case study of the usefulness of a formal feasibility study in a situation involving an elevated cancer rate and contaminated municipal water supply wells surrounding a federal superfund site.
