REPRESENTATIVE EXPERIENCE

As a Civil and Environmental Engineer for Weber, Hayes and Associates, Mr. Drizin designs water supply and wastewater treatment systems, and leads environmental cleanups. His water supply and wastewater work range from municipal supply wells to on-site wastewater disposal systems in difficult settings. Most of the environmental cleanup work is related to releases of fuels and solvents from underground storage tanks. This work includes the design and implementation of site assessments to determine the extent of soil and groundwater contamination; risk analyses to determine cleanup goals, conducting feasibility studies to determine the most appropriate remedial technology to reach those goals given site-specific conditions; and designing, permitting, installing (including construction management) and operating soil and groundwater cleanup systems. He is also responsible for preparing technical reports documenting all phases of assessment, design, operations and monitoring, and closure of cleanup systems for regulatory agencies.

SELECTED PROJECTS

Currently directing a complex drilling/multi-level monitoring well installation program to characterize a MTBE release and determine potential migration pathways from an underground storage tank to a Public Drinking Water Supply well in Los Osos, California. The next phase will be developing a Cleanup Plan.

Prepared specifications for a municipal water supply well and pump, City of Seaside, Ca.

Designed an intermittent sand filter system for wastewater treatment at a site with little to no natural soils for wastewater disposal. The final design incorporated hydrogeologic studies that indicated deep disposal of treated groundwater would still provide sufficient separation from local groundwater.

Designed, installed and operated a Soil Vapor Extraction System/Air Sparge System for cleanup of petroleum hydrocarbon contaminated soil and groundwater in-situ. This project is currently in the post-cleanup monitoring phase.

Designed, installed and operated a Dual Vacuum Extraction System for cleanup of petroleum hydrocarbon contaminated soil and groundwater in low permeability soils. Case closed by the local regulatory agency.

Designed, permitted, oversaw construction, operated, and supervised decommissioning of a biopile for ex-situ degradation of stoddard solvent in soil. Case closed by the local regulatory agency.

Supervised the installation, start-up, operations and monitoring, closure assessment, and decommissioning and removal of a soil vapor extraction system for remediation of volatile organic solvents in to a depth of 80 feet. Case closed by the local regulatory agency.

Managed the assessment and remediation of soil and groundwater contaminated by leaking underground storage tanks for a nationwide trucking company at various sites around the U. S. Reviewed work plans, site assessments, feasibility studies, corrective action plans, monitoring reports, and closure plans in light of state-specific guidelines.
Coordinated cleanup activities with upgrades and or replacement of fuel systems.

Supervised the installation, start-up, operations and monitoring, and reporting for a groundwater pump and treat system for remediation of a sandy aquifer contaminated by gasoline.
