Environmental Crimes/Marine Unit 

The Environmental/Marine Unit is responsible for the investigation of unlawful dumping cases that include a wide variety of materials from household garbage to chemical spills. A close working relationship with Federal, State and local environmental compliance agencies is essential to the protection of our natural resources. The Environmental/Marine Unit works closely with the Agriculture Crimes Unit as many of the cases investigated by the unit occur on agriculture lands. The unit is also tasked with investigating major animal cruelty cases including pitbull dog fighting and rooster fighting rings.

The Polk County Sheriff's Office Environmental/Marine Unit is also responsible for the patrol and enforcement of boating laws and ordinances on Polk's 500 + lakes.


Utilizing rapid response patrol boats, airboats, and specialized search and recovery vessels, the unit also responds to boating accidents, missing boaters, drowning investigations, and search and recovery operations.  The Environmental Crimes/Marine Unit manages a 15-member underwater search and recovery team to supplement drowning investigations, criminal investigations and evidence recovery.
