REPRESENTATIVE EXPERIENCE


As a Senior Civil and Environmental Engineer for Weber, Hayes and Associates, Mr. Drizin designs and
engineers water supply and wastewater treatment systems, and leads environmental cleanups.

Mr. Drizin’s water supply design and engineering work ranges from municipal supply wells to
commercial and industrial water wells, including matching client needs with well yields, and specifying
well materials, pumps, appurtenances, and data acquisition and control systems.

Mr. Drizin’s wastewater design and engineering work ranges from on-site wastewater treatment systems
for small communities to wastewater treatment systems for individual dwellings in difficult geologic
settings, utilizing the full range of available technologies.

Most of Mr. Drizin’s 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
contaminated sites for regulatory agencies.

SELECTED PROJECTS


Direct 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. Developed an innovative soil vapor extraction/air
sparging/groundwater circulation well Cleanup Plan. Supervised the installation and operation of the
cleanup system. The system drastically reduced concentrations of MTBE and other gasoline
contaminants, and the case was recently closed by the California Regional Water Board.

Design, install and operate a Soil Vapor Extraction System/Air Sparge System that incorporates a 300-
foot long horizontal air spage well for cleanup of petroleum hydrocarbon contaminated soil and
groundwater. The site is being reviewed by the Regional Water Board for closure.
Prepare plans and specifications for a municipal water supply well, pump, connecting piping,
appurtenances, and instrumentation, City of Seaside, Ca.

Prepare plans and specifications for the potable water supply system for a quarry in the Salinas Valley,
Ca., including connecting piping from the well, appurtenances, and instrumentation.

Prepare plans and specifications for wells, pumps, piping, and appurtenances for an agricultural water
supply project using aquifer storage and recovery in the Pajaro Valley, Ca.

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

Design, install and operate a Soil Vapor Extraction System/Air Sparge System for cleanup of petroleum
hydrocarbon contaminated soil and groundwater in-situ. Case closed by the local regulatory agency.
Design, install and operate 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.

Design, permit, oversee construction, operate, and supervise decommissioning of a biopile for ex-situ
degradation of stoddard solvent in soil. Case closed by the local regulatory agency.
Supervise 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 unsaturated
soils to a depth of 80 feet. Case closed by the local regulatory agency.

Manage 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.

Supervise 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.
