The Thouin Sand Pit site is located in L'Assomption, Quebec, approximately 20 km northeast of<br />
Montréal and is characterized by a thin silty sand layer (2 m or 6.6 ft) underlain by a 30 m (98 ft)<br />
thick deposit of silty clay. Waste oils and organic compounds dissolved in water have been flowing<br />
in ditches and nearby creeks. Historic activities at the site involved disposal of waste oils from<br />
petroleum refining and other industrial activities. The NAPL present at the site consists of a mixture<br />
of chlorinated and nonchlorinated hydrocarbons with a density greater than water. Sediments at<br />
the site consist of approximately 2 m (6.6 ft) of silty sand underlain by approximately 30 m (98.4 ft)<br />
of siltly clay.<br />
During the fall of 1994, a field test of aquifer washing using a micellar solution was conducted at<br />
the Thouin Sand Pit. The overall objective of this effort was to evaluate the use of a washing<br />
solution including a surfactant, an alcohol, two solvents, and a mobility control blank of polymer to<br />
recover a DNAPL. The washing solution was designed after several laboratory column<br />
experiments and after construction of several phase diagrams. Based on extensive laboratory<br />
work, a chemical system involving the following components was selected:<br />
· n-Butanol<br />
None<br />
None<br />
