About Hil7
The primary purpose of Hil7 is tailings. Tailings dams contain waste material from mining operations — typically a slurry of finely ground rock left over after valuable minerals have been extracted. These structures require ongoing monitoring because tailings can contain heavy metals and other contaminants. The dam is owned by The Mosaic Company (private). It impounds the Unnamed Pond near Tampa.
The dam stands 13 feet tall and stretches 4,752 feet across, creates a reservoir covering 36 acres, and has a maximum storage capacity of 889 acre-feet.
