Waste Management Practices
in Drycleaning Operations
(The information in this newsletter has been gleaned from an EPA sponsored site http://www.drycleancoalition.org and enhanced with pictures obtained from the Web.)
Contact water is any water that has come into contact with drycleaning solvents or drycleaning solvent vapors. Contact water contains some level of dissolved solvent.
In 1988, the International Fabricare Institute conducted a study of drycleaning equipment and plant operations, including waste disposal practices.
Over 70.7% of the 909 drycleaning operations that responded to the survey indicated that separator water was being discharged to either a sanitary sewer or a septic tank.
Septic Tank
It is reasonable to conclude that historically, sanitary sewers and septic tanks have been the most common disposal points for contact water (separator water, vacuum water and mop water).
Old Sewer Line
Old Sewer Connection
A study of drycleaning solvent contamination in California concluded, “The main discharge point for dry cleaners is the sewer line.”. Studies conducted in California have found evidence of the presence of free-phase PCE in sewer lines serving dry cleaning plants.
Other disposal practices for contact water have included discharge to the ground, discharge to storm sewers and soakage pits, and discharge to blind drains. Contact water has reportedly been discharged to cooling towers and boilers at drycleaning facilities.
Blind Drain
