ABOUT THE OWNER

Dr. Stover has extensive experience in setting up and supervising pilot scale and laboratory scale treatability investigations for development of process design criteria. He has supervised biodegradability investigations including treatability and fate mechanisms of specific organic and inorganic chemicals found in various types of industrial and hazardous wastes. He has participated in the development of effluent limitations guidelines and standards of performance for the various chemical industries, development of the first hazardous waste management plans for the States of Pennsylvania and New Jersey, and development of wastewater treatment plant designs for various industrial categories.

Dr. Stover has developed and supervised wastewater sampling and treatability programs, biomonitoring and aquatic toxicity evaluations, as well as toxicity identification/toxicity reduction programs for in-plant control and end-of-pipe treatment for the various chemical, pharmaceutical, photographic, carbon black, adhesives and sealants, iron and steel, beverage and food processing industries. Dr. Stover has managed and supervised wastewater sampling and characterization programs for monitoring of priority pollutants. These programs have included physical/chemical and biological treatability studies and monitoring of full-scale unit processes for removal and performance evaluations. He has provided start-up, training, troubleshooting and operations advice services for wastewater treatment in the various industrial categories and municipal facilities. Dr. Stover has been involved in several hazardous waste site (including Superfund site) remediation projects. He has over fifty (50) technical publications related to hazardous waste management.

Dr. Stover has directed pilot plant programs for evaluating activated carbon treatment of various types of industrial wastewaters. He has directed an EPA funded R&D program investigating the feasibility of ozone disinfection for achieving high level disinfection of total coliform bacteria employing full-scale ozone generating and contacting equipment.

He has conducted numerous groundwater remediation studies including drinking water treatability investigations for taste and odor control and control of organics employing chemical treatment, ozone, activated carbon, air stripping, and biological treatment.

From January 1978 to September 1980, Dr. Stover served as a member of Metcalf & Eddy’s Technical Practice Committee providing quality control and detailed evaluations at key stages of all water and wastewater treatment plant designs. His responsibilities as a member of this committee began at the initial concept development stage and required detailed evaluations through completion of the final detail design.

As the author of over two hundred-eighty (280) technical articles, Dr. Stover’s contributions have been published in such periodicals as Journal Water Pollution Control Federation, Water Environment Research, Journal American Water Works Association, Water Engineering & Management, Civil Engineering, and Industrial Wastes. Dr. Stover is a co-author of The Handbook of Hazardous Waste Management published by Technomic Publishing Company of Westport, “Connecticut and Toxic and Hazardous Waste Disposal Volume Four,” published by Ann Arbor Science Publishers, Inc. During Dr. Stover’s term as Chairman of the Hazardous Waste Committee of the Water Pollution Control Federation he was responsible for developing the Hazardous Waste Treatment Processes, Including Environmental Audits and Waste Reduction (Manual of Practice FD-18), Hazardous Waste Site Remediation Management, and Hazardous Waste Site Remediation: Assessment and Characterization publications, as well as coordinating WEF annual conference workshop on hazardous waste management, annual program sessions on hazardous waste management, and other outreach programs for dissemination of hazardous waste management information and public education. Dr. Stover served as the Project Director and Principal Author for the development of the Environmental Protection Agency’s Design Manual For Municipal Wastewater Disinfection (EPA/625/1-86/021).

Specific projects for nutrient removal in industrial wastewater have included soy bean processing, various types of food processing wastewaters, fertilizer, chemical, petrochemical, and refinery wastewaters. These nutrient removal projects have included treatability and pilot-scale studies, concept and process engineering, detail design and construction engineering and operations services. A list of relevant technical publications on nitrogen and phosphorus control follows.

Dr. Stover’s experience with anaerobic treatment has included many types of industrial wastewaters, as well as anaerobic sludge digestion, with various anaerobic treatment technologies. Examples of industrial wastewater projects have included palm oil wastes, fuel alcohol production, brewery, confectionary, dairy, rice processing, soy bean processing, corn processing, fish processing, potato processing, slaughterhouse, and fermentation wastewaters. Dr. Stover has extensive experience with various anaerobic treatment technologies including lagoons, suspended growth systems, fixed-film systems, upflow anaerobic sludge blanket reactors, and hybrid reactor designs. Dr. Stover has also conducted extensive research and development and process development activities with anaerobic systems.

Dr. Stover has extensive experience with biological aerobic thermophilic treatment processes including both industrial wastewater treatment and sludge digestion. Aerobic thermophilic projects have included treatability and pilot plant studies, concept and process engineering, detail design, construction engineering, startup and operator training, operations manuals, and operational troubleshooting services. A list of relevant technical publications on aerobic thermophilic treatment follows.

Dr. Stover’s graduate work at Oklahoma State University was concentrated in the areas of microbiology and biochemistry. His research and consulting experience has continued to center around the microbiological and biochemical aspects of wastewater treatment. Of particular interest has been his continued work in the area of identification and control of nuisance microorganisms, especially filamentous bacteria, during biological treatment. Every operational troubleshooting, problem solving, and operational process control project with biological treatment involves microbiological testing and identification. A list of relevant wastewater microbiology publications follows. Dr. Stover routinely performs microscopic analyses and identification of the microbiology associated with biological wastewater treatment plants. As a result of his experience and expertise in wastewater microbiology, Dr. Stover provides wastewater microbiology pre-conference workshops at The Water Environment Federation (WEFTEC) annual conferences.
