Engineering controls (ECs) are physical controls or barriers that prevent human exposure to contamination (for example, slurry walls, capping, or vapor intrusion liner).

Long-Term Contaminant Management Using Institutional Controls (IC-1)
Section 1 (Introduction)
Addresses long-term contaminant management using physical controls or barriers to prevent exposure to contaminants.

Mining Waste Treatment Technology Selection (MW-1)
Administrative and Engineering Controls
Describes how engineering controls (ECs) generally consist of physical measures designed to minimize the potential for exposure to contamination by limiting direct contact with contaminated areas.
