which feed Lake Hartwell – USACE

 Arsenic in surface soils as high as 2,000

mg/kg, EPA established Removal Action Level is 40 mg/kg

 Arsenic found in creek

Waste Streams

 Acids  Acid Chlorides  Acid Oxidizer Chloride  Acid Oxidizer Rinse  Acid Solids  Arsenic floor sweep  Bases  Base Solids  Biodiesel  Flammables  HHW  Neutral Chlorides

Challenges

 Unknowns – slow going

– Shock sensitive, air reactive, radioactive

chemicals

 Heat – over 90 since we started  Lack of rain  Creek  Nature – snakes, poison ivy, wasps, gophers  Arsenic EVERYWHERE!!!  Wait for it……

And We Found Cadmium!

  • Drainage pipe that led from

the building to a septic tank

  • Soils surrounding the septic

tank failed TCLP test for Cd.

  • Cd contaminated soil will be

treated with Free Flow stabilizing agent at a rate of 3 to 5%.

  • Cost per ton of Free Flow

around $275.

To date

 Hazcatted over 950 containers  Bulked over 7,955 gallons (liquid) and

5,395 gallons (solid) of materials

 Excavated over 7,500 cu yds of As and

Cd contaminated soil removed

 Demolition of buildings 1 and 2
