PUBLIC HEALTH ASSESSMENT

ELECTRO-COATINGS, INCORPORATED
CEDAR RAPIDS, LINN COUNTY, IOWA


CONCLUSIONS

  1. ATSDR and IDPH have concluded, based on the information reviewed, that the site poses no public health hazard. Potential exposure pathways have been identified, but exposures can be avoided if recommendations made in this public health assessment are followed.

  2. Possible exposure to non-site related contamination in Cedar Lake can be avoided if people adhere to the fishing and swimming advisory issued for the lake.

  3. Possible exposure to site-related contamination through use of groundwater can be avoided if municipal wells, which may be cross-gradient of the site, are monitored routinely for contamination. Also, exposure can be avoided of new wells are not drilled in areas west of the site. If private wells are developed in that area, they should be tested and monitored.

RECOMMENDATIONS

  1. Be sure that warning signs about fishing and swimming in Cedar Lake are clearly visible and legible.

  2. Continue to monitor any municipal wells, located cross-gradient of the site. Consider institutional controls prohibiting development of private wells in areas west of the site where contaminated groundwater may migrate. If wells are developed in that area, a monitoring program for those wells should be instigated.

PUBLIC HEALTH ACTION PLAN

This section contains a description of actions to be taken by ATSDR, IDPH, and other governmental agencies for the site. The purpose of the public health action plan is to ensure that this public health assessment not only identifies public health hazards, but provides a plan of action designed to mitigate and prevent adverse human health effects resulting from exposure to hazardous substances in the environment. The public health actions to be implemented for this site are as follows:

A. Actions Undertaken

  1. Closure of a chromium dipping tank in 1976.

  2. Leak prevention / monitoring measures in all chrome plating tanks.

  3. Removal of chromium contaminated soil in 1992.

  4. Placement of the site on the state Registry of Hazardous Waste or Hazardous Substance Disposal Sites. This action prevents sale or significant change in use of the property without approval by IDNR. Furthermore, notice of this listing was also recorded on the property deed.

  5. Remedial action taken has been monitoring groundwater and includes a contingency plan for groundwater pump-and-discharge to the publicly owned treatment works (POTW), if indicated or necessary.

B. Actions Planned

  1. Monitoring will continue with a contingency plan for groundwater pump-and-discharge to the publicly owned treatment works (POTW), if indicated or necessary.

  2. New environmental data will be reviewed that may become available to determine if other public health actions are indicated.

  3. ATSDR and IDPH are available to address any community concerns that may arise during remedial activities at the site.

  4. IDPH will ensure that local authorities, who have input on siting private wells are made aware of the groundwater plume and results of this public health assessment
