- Occurred on 23rd May 2003
- solvent-based product
- storage, handling and packaging
3
Background (The Problem)
Common Land
Mixed-housing Area
4
Background (The Problem)
Contaminated area
River Hull
Serious effects on local community

Solution

• Patented E-clay technology from Envirotreat
• Advanced chemical fixation (immobilisation)
  process
• Effective in both soil and ground water

6
Solution - E-clay
Transition Metal Salts
7
Solution - E-clay
Quaternary Ammonium Salts
8
Solution - E-clay
Reactive Pillaring Agents
9
Solution - E-clay

• Reactive environment
• Broad range of organic and inorganic pollutants
• Designed on a site-by-site basis
• Highly efficient, multifunctional, cost-effective
  treatment media

10
Solution - E-clay

• Applied in situ or ex situ

• In our case, an ex situ, on-site, method was
  employed

- excavated, treated and reused

• Testing for leaching and physical properties

11
Alternatives

• For contaminated soil
• Bioventing
• In situ Bioremediation technique
• Stimulates the natural in situ biodegradation by
  providing oxygen to existing soil microorganisms

12
Alternatives

• For contaminated water
• Advanced Oxidation Processes
• Ex situ chemical treatment
• Used to destroy organic contaminants as water
  flows into a treatment tank
• By ultraviolet (UV) radiation, ozone, and/or
  hydrogen peroxide

13
Results

• 1.7 acres of contaminated area (6,500m3) was
  treated in less than two months
• Full EA approval
• The E-clay treated soils
• Disposed of at a landfill,
• Non-hazardous
• One-step Envirotreat process can make the soil
  inert
• New Factory is nearing completion

14
The End

• Full production scheduled in Summer 2005
