Contaminated Sites Database - This allows the public to search and find information about sites and print out results.
Environmental Laboratory Certification - Laboratories reporting environmental data to the Iowa DNR must be certified.
Cumulative Risk Calculator - The cumulative risk calculator can assess risk to potentially exposed parties, based on three standard exposure scenarios, from multiple contaminants and multiple media (i.e., groundwater, soil, and air).
Statewide Standards - Standards prescribed in the LRP which represent concentrations of contaminants in groundwater and soil for which normal, unrestricted exposure is considered unlikely to pose a threat to human health.
Environmental Covenant - The Department drafted a model environmental covenant for use in the LUST and LRP programs. There are certain provisions that must be incorporated into the covenant and there is broad discretionary authority to incorporate other provisions.
