EEI Staff
Timothy A. Lester, REA II
Managing Principal, Senior Environmental Manager
Tim Lester has worked for over 20 years in the fields of environmental investigation, remediation, regulatory evaluation and related fields. As a remediation specialist, he has been on the cutting edge of remediation applications of soil vapor extraction and bioventing. In 1987 Tim was involved in the fabrication and field testing of a 1,000 cfm SVE system which utilized the first Allied-Signal catalyst applied for SVE purposes. Since that time, he has designed and implemented SVE bioventing systems for fuels, PNA (CA superfund), heavy oil (utility RCRA site) and refinery remediation projects. Tim is one of the small cadre of REA II's registered in the State of California to manage complex RCRA projects. Tim is trusted by our clients to provide regulatory information and design, project management and strategy, expert witness, and remediation consulting and field solutions on an on-going basis.
