PUBLIC HEALTH ASSESSMENT
LOXAHATCHEE NURSERY
PALM CITY, MARTIN COUNTY, FLORIDA
On the basis of available environmental and toxicologic information, ATSDR concludes that the Loxahatchee Nursery site in Palm City, Florida, poses no apparent public health hazard. This determination is based on the following:
The Loxahatchee Nursery site is not currently fenced. One pond is located on site. During ATSDR's site visit, the staff noted that the remaining on-site structures were in a state of disrepair. ATSDR determined that the on-site pond and dilapidated structures could pose a potential physical hazard to area residents, especially children, who trespass on-site.
The future use of the site has not yet been determined; however, it is presumed to be residential.
To date, the on-site pond surface water and sediment have not been sampled. Given that only low
levels of contaminants were detected in on-site soils and drainage ditch sediments, it is unlikely
that the on-site pond contains elevated levels of contaminants. However, ATSDR cannot evaluate
the public health implications resulting from exposure to this on-site pond without environmental
data.
The actions described in this section are designed to ensure that this public health assessment identifies public health hazards and provides a plan of action to mitigate and prevent adverse health effects resulting from exposure to hazardous substances in the environment.
ATSDR includes a commitment to follow up on this plan and ensure that it is implemented. Public health actions to be implemented are as follows:
