What Are the Risks at the Site?

Risks and pathways likely to be addressed by the cleanup include health risks from people ingesting or touching contaminants in soil and groundwater. Contamination resulted from pesticide-related activities at the site. PRPs removed a large part of the contaminated soil source and cleaned up shallow soil to levels that allow for commercial and industrial uses. Some below ground soil contamination remains in place; it is covered by clean fill and/or concrete/asphalt cover. Helena Chemical Company continues to operate a pesticide distribution warehouse on the site. The area is fenced and secured.

EPA is evaluating options to clean up the groundwater HCH and xylene contamination through a series of pilot-scale studies. Groundwater contaminants at the site include VOCs, which could pose a risk to human health through vapor intrusion. All buildings above the VOC-contaminated groundwater are ventilated, open-sided warehouse buildings, which prevent VOC accumulation.

All area businesses and the residence north of the site use the public water system for drinking water. In addition, EPA and the Southwest Florida Water Management District have entered into an agreement. The District regulates the permitting process and construction of water wells within the area of the site’s groundwater contamination, as well as the areas of groundwater contamination at the two neighboring Superfund sites.

Status at this
Superfund Site
What does this mean?
Human Exposure Under Control Yes Yes means assessments indicate that across the entire site:
  1. There are currently no unacceptable human exposure pathways; and
  2. EPA has determined the site is under control for human exposure.

No means an unsafe level of contamination has been detected at the site and a reasonable expectation exists that people could be exposed.

Insufficient data means that, due to uncertainty regarding exposures, one cannot draw conclusions as to whether human exposures are controlled, typically because:
  1. Response to the contamination has not begun; or
  2. The response has begun, but it has not yet generated information sufficiently reliable to evaluate whether there are currently any unacceptable human exposure pathways at the site.
Groundwater Migration Under Control Yes

Yes means EPA reviewed all information on known and reasonably expected groundwater contamination. EPA concluded the migration of contaminated groundwater is stabilized and there is no unacceptable discharge to surface water. EPA will conduct monitoring to confirm that affected groundwater remains in the original area of contamination.

No means EPA has reviewed all information on known and reasonably expected groundwater contamination, and the migration of contaminated groundwater is not stabilized.

Insufficient data means that due to uncertainty regarding contaminated groundwater migration, EPA cannot draw conclusions as to whether the migration of contaminated groundwater is stabilized.

Construction Complete No

Yes means the physical construction of the cleanup is complete for the entire site.

No means either physical construction is not complete or actions are still needed to address contamination.

Sitewide Ready for Anticipated Use No Yes means:
  1. All cleanup goals affecting current and reasonably anticipated future land uses of the entire site have been achieved, so there are no unacceptable risks;
  2. All required land-use restrictions or other controls have been put in place; and
  3. The site has achieved Construction Complete status.

No means that one or more of these three criteria have not been met. However, a site listed as no may still have redevelopment occurring on portions of the site and may be eligible for additional redevelopment.
