Environmental Enlightenment #213
By Ami Adini - Reissued August 11, 2017

This is a SHORT, LIGHT and SIMPLE newsletter. Its purpose is to rekindle in the initiated terminology they have once learned, and enlighten the uninitiated on terms they may have heard but never knew the meaning of.

Power of Simplicity
The EPA’s Citizen’s Guide to Cleanup Technologies

Series 12: Capping

See our Newsletter, Environmental Enlightenment #200, for introduction to one highly valuable, plainly written series of Citizen’s Guides published by the EPA at http://www.clu-in.org/products/citguide

With this issue we introduce the EPA’s Citizen’s Guide to Vapor Intrusion Mitigation. You can reach it through the hyperlink under the blue header below.


Caps provide protection from injurious elements in the environment.

It is the nature of caps that they sit tight with the elements they defend or protect from.


We have the baseball cap.

And we have the sanitary landfill cap.


Caps block an entry or prevent an exit; depends on where the protected receptor is relative to the injurious factors.

The goal of environmental protection is practical defense of public health and the ecosystem.

In many cases, encapsulation of contaminated substances in place will provide better and safer protection than disturbing them in attempts at removal.


Capping can be integrated into a commercial, even residential, redevelopment of the site.

It can be a parking lot pavement.
