Andrew D. Horwath, P.E.

Mr. Horwath has over 10 years of experience in the environmental consulting industry with his main areas of expertise being remediation of petroleum and chlorinated solvents.  He has directed numerous subsurface investigations of varying size and scope to delineate soil and groundwater impacts at facilities impacted with a wide range of contaminants.  Mr. Horwath has experience in all phases of remediation including performing feasibility studies, pilot testing, remedial design, implementation, and oversight of mechanical remediation system operations & maintenance.  He has designed a variety of technologies including: fluid flushing technologies such as ozone and air sparging, soil vapor extraction (SVE), single pump multi-phase extraction (MPE), bioventing, and biosparging; in-situ chemical oxidation (ISCO); and enhanced anaerobic bioremediation.  These technologies have been applied using both vertical and horizontal remediation wells.  In recent years, more attention has been given to the vapor exposure pathway by state regulators and the EPA.  Consequently, Mr. Horwath has directed numerous vapor intrusion investigations, designed remediation strategies to address the vapor intrusion pathway, and designed sub-slab depressurization vapor mitigation systems as engineering controls for residences, large industrial buildings, and schools.
