Need for System of Data Management for Risk Assessment

EPA needs more adequate mechanisms to compile and maintain databases for use in health-risk screening and assessment.

EPA should review its data-management systems and improve them as needed to ensure that the quality and quantity of the data are routinely updated and that the data are sufficiently accessible for risk screening and risk assessment. Its responsibilities under CAAA-90 should be prominent in this review and revision.
