Brownfields - Cattle Dip Vats

Cattle Dip Vats (CDVs)

Cattle Dip Vats were constructed beginning in 1910 as a federal mandate to eradicate cattle tick fever that started entering Florida in the early 1900s. Cattle were corralled and run through concrete dipping vats filled with a solution containing arsenic, DDT and other organochloro pesticides. The program was terminated in the late 1960’s when it was believed that cattle tick fever was eradicated. Some of these structures remain in place where the toxic solution may impact both the soil and groundwater. There are eight known CDVs throughout The Seminole Tribe of Florida’s (STOF) Tribal Lands. Remediation of these sites has been underway to protect both the health of the environment and the surrounding population. A list of CDV sites are listed below:

  • West Feeder CDV (Big Cypress Reservation)
  • Bull Pasture CDV (Big Cypress Reservation)
  • Tucker Ridge CDV (Brighton Reservation)
  • Cotton CDV (Brighton Reservation)
  • Johnny Bow Legs CDV (Brighton Reservation)
  • Red Barn CDV (Brighton Reservation)
  • Marsh Pens CDV (Brighton Reservation)
  • Food Bank Cowpens CDV (Big Cypress Reservation)

For additional information pertaining to CDVs please contact the Seminole Tribe of Florida. Environmental Resource Management Department at 954-965-4380.

Big Cypress - West Feeder Cattle Dip Vat (CDV)

Location: Remote wooden hammock south of County Rd. 833, Hendry County, Florida

Area: Less than 1 acre.

Site Information: The West Feeder CDV’s concrete structure was removed in 2006 and disposed of properly. Additional soil and groundwater testing of the site was performed by a Phase II Environmental Site Assessment (ESA) in 2007 and warranted additional source removal activities of contaminated soils. Contaminated soils were successfully removed and disposed of properly in 2009. To determine the groundwater quality in the area where the soils were excavated, in January 2012, ERMD personnel coordinated and supervised the installation of five monitoring wells for assessment of the groundwater. The assessment which included the collection of groundwater samples and analysis of parameters of concern such as arsenic and organochlorine pesticides indicated that concentrations of these parameters did not exceed the Florida Department of Environmental Protection (FDEP) Groundwater Cleanup Target Levels. The results of the assessment indicated that the soil remedial activities conducted in 2009 were successful in mitigating not only the impacted soils but the source for groundwater contamination. Based on the soil remediation and results of the groundwater assessment, no further remediation activities are warranted at this time.

Big Cypress - Bull Pasture Cattle Dip Vat (CDV)

Location: Along Herd Improvement Road, south of Snake Road, Hendry County, Florida

Area: Less than 1 acre

Site Information: Historical records of the Bull Pasture indicate that a former CDV may be located at this project site. In 2011, a geophysical investigation was completed using ground penetrating radar (GPR) to determine the possible presence and location of the former CDV. The geophysical investigation could not determine the CDV location within the surveyed area of the project site. In September of 2011, the Environmental Resource Management Department (ERMD) conducted a soil assessment in the surveyed area encompassing the existing cow pen in an effort to determine the soil conditions and if possible, the location of the CDV. The soil assessment encompassed the advancement of borings and analysis of soil samples for arsenic. Based on the laboratory results which indicated that just three locations showed concentrations of arsenic above background levels, In January 2012, ERMD conducted a groundwater assessment to determine the groundwater conditions in these areas. Groundwater samples collected and analyzed for arsenic and organochlorine pesticides did not reveal the presence of these contaminants. Based on the results of the soil and groundwater assessment, no further action can be completed at this time unless new information becomes available as to the location of the CDV.

Brighton - Tucker Ridge Cattle Dip Vat (CDV)

Location: Northeast corner of the Brighton Reservation Glades County, FLEast corner of the Brighton Reservation, Glades County, Florida

Area: Less than 1 acre.

Site Information: The Tucker Ridge CDV is located in a shell rock quarry that is currently active. The CDV was initially identified by degradation of vegetation both in and surrounding the dip vat. Since the initial identification, the CDV has been removed and properly disposed of. Soil and groundwater samples have been analyzed to determine the impacts of arsenic and organochlorine pesticides. Removal of contaminated soil was completed in 2004 and disposed of properly. The Tucker Ridge CDV was backfilled and leveled. No further action is warranted at this time.

Brighton - Cotton Cattle Dip Vat (CDV)

Location: Remote wooden hammock, NE corner of reservation, Glades County, Florida

Area: Less than 1 acre.

Site Information: The Cotton CDV is located in a remote wooden hammock surrounded by palmetto trees. In 2004, the CDV was removed and disposed of properly. Soil and groundwater samples have been analyzed to determine the impacts of arsenic and organochlorine pesticides. Additional soil and groundwater testing was completed in 2013. Proper removal and disposal of contaminated media will occur in 2015.

Brighton - Johnny Bow Leg’s Pasture Cattle Dip Vat (CDV)

Location: West side of BIA Highway 283, Glades County, Florida

Area: Less than 1 acre.

Site Information: The Johnny Bow Leg’s Pasture CDV was removed and properly disposed of in 2004. Soil samples have been analyzed to determine the impacts of arsenic and organochlorine pesticides. Based on the analytical laboratory results no further remediation actions are needed for this site.

Brighton - Marsh Pen Cattle Dip Vat (CDV)

Location: Approximately 2.5 miles due west of County Road 721 (Reservation Road), Glades County, Florida

Area: Less than 1 acre.

Site Information: The original CDV was found and the structure was removed in 2003. Preliminary assessment was completed in 2012 and it was found that both soil and groundwater contamination existed at the site. A limited site assessment completed in 2014 found environmental impacts to the groundwater and soils. Based on these assessments findings, further sampling, delineation and analysis will need to be performed on this site.

Brighton - Food Bank Cow Pens Cattle Dip Vat (CDV)

Location: Approximately 100 feet west of County Road 721 (Reservation Road) immediately south of the northern entrance to the Brighton Reservation in Glades County, Florida

Area: Less than 1 acre.

Site Information: An Environmental Site Assessment was performed on the Food Bank Cow Pens CDV in 2004. Source removal activities that included groundwater removal occurred in 2013. At this time groundwater monitoring wells were installed. Those wells were sampled in 2014 and were found to be above FDEP clean-up target levels. Further soil sampling may be warranted and groundwater remediation will be required for this site.

Brighton - Red Barn Cattle Dip Vat - Glades County, FL

Location: Approximately three miles west of County Road 721 (Reservation Road) on Harney Pond Road in Glades County, FL. Site is located 600 feet west of Harney Pond Road immediately south of Harney Pond Canal off Madison Nenuce

Area: Less than 1 acre.

Site Information: The Red Barn Brownfield site consists of a CDV and a pole barn which served as a Drum Staging Area. The former Drum Staging Area included two permanent structures; a pole barn and a concrete block structure equipped with an above ground storage tank (AST) and underground storage tank (UST) for vehicle fueling. In 1999, the discarded drums and petroleum storage tank were removed and disposed of properly. Analytical laboratory results of soil and groundwater samples were performed within the immediate vicinity of the former Drum Staging Area.
In 2004, the CDV’s sludge and concrete structure were removed and disposed of properly. Soil and groundwater samples have been analyzed to determine the impacts of arsenic and organochlorine pesticides within the immediate vicinity of the CDV. A groundwater pump and treat system was installed in 2008 to remediate the arsenic in the groundwater. Water restrictions have been implemented on the two properties surrounding the Red Barn Brownfield site. These sites are now serviced by the local water utility and no use of irrigation or drinking water is permitted from on-site wells. Source removal at the site was conducted in 2012. Groundwater monitoring wells were reinstalled. The wells have been sampled since that time and then show that the levels of arsenic in the groundwater are still well above the FDEP clean-up target levels. A pilot study for in situ remediation of arsenic in groundwater is planned to be conducted in 2015.
