Representative Projects:


Solid and Hazardous Waste / Hazardous Materials Projects:


Energy Production from Anaerobic Digestion: Pilot-scale studies funded by the U.S. Department of Energy and National Science Foundation were focused on the production of methane from biomass in sewage treatment sludge and municipal solid waste.  In addition to the energy production benefit, the project would significantly reduce the quantity of sewage sludge and municipal solid waste requiring disposal in landfills.  Follow-on work included similar investigations of different feed stocks, including agricultural residues such as corn stover and beef feed lot wastes.


Collection Vehicle Routing: For the Army Corps of Engineers, solid waste collection vehicle routing studies were conducted at military bases, reducing the collection vehicle travel distances by an average of seven percent without reducing the level of service.  The methodology included both computer-based optimization techniques as well as manual rescheduling and load balancing.


Oil Spill Prevention/Control: A major west-coast oil company requested audits to improve spill prevention and control measures at their company-owned bulk fuel terminals nationwide.  As part of that project, Dr. Quindry inspected each facility for potential risks, such as insufficient spill containment, faulty engineering design or construction, inadequate monitoring and control equipment, and unsafe operating practices.  Follow-on work included re-writing and re-certifying Spill Prevention, Control and Countermeasure (SPCC) Plans, the redesign of tank farm dikes, modifications of underground piping and alarm systems, and development of additional worker training materials for terminal personnel.


Methane Gas Mitigation:  The site for an elementary school was near historical oil production areas, and methane gas was determined to be a potential hazard in building construction.  A methane gas mitigation system was designed and approved for inclusion in the construction.  The design included innovative measures that provided multiple layers of protection for the buildings and occupants, and on-going monitoring to assure continued compliance with safety standards.  School construction will be completed in the spring of 2011.


Water Quality and Water Supply:


SB 610/221 Water Supply Assessment Sr. Engineer:  California regulations require an independent water supply assessment for new developments that may place an additional demand on available supply.  An independent assessment of the water supply system for the City of Galt, California was conducted as part of an EIR process for a large commercial development.  Estimates of water demand for the new development were generated through an evaluation of similar facilities that were in  similar geographic locations.  By comparison of the new demand with the available and planned supply, it was possible to show that the project would have very little impact and not endanger the ability of the City’s water department to provide sufficient water to the community.


Water Reuse Study Project Manager:  A Southern California water district had proposed to use recycled water to recharge a local aquifer for indirect potable reuse.  The proposal had been rejected on the basis of widespread public pressure, but the client’s desire to complete the project lead to a study of the technologies that would be required to produce higher quality water that could potentially overcome public resistance.  A preliminary design and cost estimate was developed for a highly treated wastewater facility, based on the likely contaminants that were present in the source wastewater after conventional treatment.  A treatment scheme including micro filtration, reverse osmosis, and UV/peroxide oxidation was proposed to achieve the highest quality of water that was economically feasible.  


Feasibility Study, Water Recycling Project Manager:  In an effort to reduce the demand for potable water and eliminate wastewater discharge permitting requirements, a California oil refinery requested a study to assess the feasibility and cost of becoming a “zero-discharge” facility with respect to industrial wastewater.  A detailed study of the refinery’s water uses and discharge, water quality requirements, available treatment technologies, and potential ‘sinks’ for reclaimed wastewater was completed.


Water System Vulnerability Assessments Senior Engineer:  Regulations developed after the terrorist attacks in 2001 required all but the smallest water systems to examine their potential vulnerabilities and to identify measures to reduce them.  The required assessments were conducted for 15 different systems in California and Arizona.


Water Integration Plan Project Manager:  A proposed seawater desalination plant at Carlsbad, California would change the potable water quality provided to many consumers in northern San Diego County.  These water quality differences present a host of challenges to the local water distributors, including the possibility of increased customer complaints, corrosion, scaling, and discoloration.  The study was conducted for the San Diego County Water Authority, and identified the potential issues and the means to minimize their negative impact.


Pipeline Design and Construction:


All-American Pipeline Senior Project Engineer:  A 1,700-mile, 30-inch diameter pipeline was designed and constructed to transport heavy crude oil from off-shore production fields near Santa Barbara, California to refineries near Houston, Texas.  The total project cost was $1.4 Billion.  Dr. Quindry’s responsibilities on the project included hydraulic and thermal modeling of the pipeline for design and location of the pipeline as well as the associated pumping and heating stations.  In addition, the proposed leak detection systems for the pipeline were modeled to validate predictions of reliability and minimum detectable leak size. 


Pipeline Feasibility Studies in Thailand Senior Engineer:  The Asian Development Bank requested technical assessments and cost estimates for potential energy pipelines Thailand.  The projects included an extension of an existing off-shore natural gas pipeline to additional gas fields, an on-shore crude oil transmission pipeline to link a deep-water port to an inland refinery, and petroleum products pipelines to link the refinery to distribution terminals throughout the country.  To complete the assessment, Dr. Quindry spent several weeks in Thailand to collect data and meet with government officials.


Environmental Site Assessment and Remediation:


Brownfields Redevelopment Principal Engineer:  Portions of the former Kaiser Steel Mill in Fontana, California were redeveloped as a municipal solid waste recycling facility, an industrial park, and a portion of the California Speedway.  Site investigations and health risk assessments were conducted under Dr. Quindry’s direction to assess the potential risk to workers and the general public at the site and to establish clean-up goals.  After clean-up operations had been completed, regulatory closure of the site was achieved.  After closure certification to the California Department of Toxic Substances Control, periodic post-closure inspections and reporting were also conducted.  Follow-on work has also included modeling and feasibility studies for construction of a waste-to-energy production plant through anaerobic digestion of the food wastes and green wastes collected at the recycling facility.


Phase I, Phase II Site Assessments, Site Remediation Principal Engineer: The client was an automobile manufacturing company that, for market coverage reasons, owned their dealership locations and leased the sites to their dealers. When a new dealership was to be opened, or an existing dealership changed hands, Dr. Quindry provided site assessment/clean-up services to enable the company to install the new or replacement dealer at a known ‘clean’ site. 


RCRA Site Assessment: An oil refinery in Hawaii was found to be discharging fuels to groundwater and to the Pacific Ocean through subsurface transport of the tidally-influenced plume.  Services provided included modeling of tidal effects on the plume and regulatory interface with EPA Region 9 personnel to minimize the regulatory impact of past violations.


Litigation Support: An aerospace facility in Orange County, California had been closed and a site remediation program completed.  The new owner – a housing developer – filed suit against the aerospace company and their environmental consultant, claiming that the site had not been adequately assessed and remediated.  The new owner contended that the site could not be developed into the residential property he had envisioned.  The litigation support services provided by Dr. Quindry to the defendant’s attorneys included a third-party assessment of the site investigation and remediation activities that were conducted by the remediation consultant, with an evaluation of the appropriateness and adequacy of those services.
