Reissued March 15, 2017

This is a SHORT, LIGHT and SIMPLE newsletter. Its purpose is to rekindle in the initiated concepts they have once learned, and enlighten the uninitiated on concepts they may have never heard of, but will understand once they are introduced to them.

Environmental Investigations in Dry Cleaning Operations
Contaminant Source Areas - Where to Sample IV

(The information in this newsletter has been gleaned from an EPA sponsored site http://www.drycleancoalition.org and enhanced with images.)

This info-letter is on drycleaning operations, their historical impact on the environment and hurdles they may pose in today’s real estate transactions. Search here for more.

Floor Drains

Sampling should also be conducted near floor drains.

If solvent wastes are discharged down floor drains plumbed with PVC piping, PCE can soften and even dissolve the PVC. The elbow joints of drain lines are particularly susceptible to dissolution.

Floor drains are commonly located in the boiler room at drycleaning facilities. Since PCE vapors are denser than air, the vapors tend to settle to the floor, particularly after the drycleaning plant has been shut down for the day. These vapors will migrate to low spots along the facility floor and floor drains.

Floor expansion joints and cracks in the floor slab are prime entry point for these vapors.


You can find past issues of "Environmental Enlightenment" at www.amiadini.com Wealth of information about environmental site assessments in the real estate transactions and issues concerning assessment and cleanup of contamination in the subsurface soil and groundwater.

Call me if you have any questions. There are no obligations.
