Ramsey County │ Annex C: Ingestion Pathway 13 2.4.4.2 Surface or Ground Water Contamination The protection of surface and ground water supplies from contamination will be coordinated with the SEOC. It is unlikely that ground water will be contaminated from an airborne release. The following are some examples of actions that may be implemented at the time of the incident. •Notify and alert downstream users with recommended protective actions. •Notify watershed districts. •Determine through sampling if water supplies in the area are safe for human and animal consumption. Determine priority for sampling of those supplies. •Collect raw water samples near the sources of contamination to establish whether gross contamination of raw water is evident. The ground water source should be monitored over an extended period of time to ensure that it has not been affected. •Isolate all affected contaminated wells. All open wells, cisterns, barrels, and other open water collecting containers should be covered to prevent radioactive fallout from hitting open water surfaces. •For storage containers that are supplied by runoff from roofs or other surface drain areas, the collecting filler pipe should be disconnected to prevent contaminants from being washed into the storage containers. •Domestic surface water supplies may be contaminated by either the accidental discharge of contaminated water or by deposition from an atmospheric release. Spring and well water should not be affected by an accidental release of radioactive material to the atmosphere or to waterways. •The contamination of domestic water supplies following discharge of contaminated water is possible only for downstream supplies using the receiving water body as a source. Adverse impact can be avoided by curtailing intake during the passage of the contaminated water. •In situations involving the contamination of a water supply, methods of providing an alternative water supply may include rationing of uncontaminated supplies, substitution of other beverages, importing water from uncontaminated areas, and the designation of certain critical users. 3.Related Training The following courses are suggested for those involved in the Ingestion Pathway function.
