PUBLIC HEALTH ASSESSMENT

SOLITRON MICROWAVE
PORT SALERNO, MARTIN COUNTY, FLORIDA


CONCLUSIONS

  1. We classify the Solitron Microwave Superfund hazardous waste site as a potentialpublic health hazard because in the future people could be exposed tocontaminated groundwater. The on-site groundwater is contaminated. If peopleinstall new wells in the contaminated aquifer, they could be at risk of becoming ill.


  2. Even though low levels of VOCs are in off-site groundwater, the levels in privatewell water are unlikely to have caused illness in the past. Nonetheless, on-sitecontaminated groundwater flows northeast, toward a residential neighborhood withprivate wells.


  3. The Solitron Building is not secure and there are no warning signs around the site.

RECOMMENDATIONS

The recommendations and advice in this public health assessment are based upon thereferenced data and information. Additional data could alter these recommendations.

  1. Prohibit new wells in the area of known groundwater contamination.


  2. Continue to identify and sample private wells northeast of the site. Prohibitdomestic use of any private wells contaminated above standards. Continue toinform residents northeast of the site of the potential public health threat resultingfrom contamination migrating to private or municipal wells.


  3. Maintain security around the site to reduce the risk ofinjury fromphysical hazards. Post hazardous waste warning signs around the property as required by FloridaStatues.

The conclusions and recommendations in this report are based on the information reviewed. If additional information becomes available, we will evaluate it to determine what, if any, additional actions are necessary. The conclusions and recommendations in this report are site specific and are not necessarily applicable to other sites.
