Robert P.G. Bowker has over 20 years experience in the planning, design, and operation of wastewater facilities, with a strong background in research and development. Mr. Bowker's areas of expertise include odor and corrosion control in wastewater collection and treatment systems, process design and detailed design of wastewater treatment plants, and alternative wastewater systems for small communities. Mr. Bowker is considered a national expert in odor and corrosion control in waste handling systems.

As a consulting engineer, Mr. Bowker has assumed management and technical responsibility for many key projects. Highlights include the following:

• Preparing, as principal author, the October, 1985 EPA Design Manual on Odor and Corrosion Control in Sanitary Sewers and Treatment Plants.
• Directing technical activities for comprehensive sulfide monitoring and corrosion control projects in the Cities of St. Petersburg, FL, Tempe/Mesa. AZ, Ashland, MA, Syracuse, NY, and Edmonton, Alberta.
• Preparing, as principal author, the EPA Report to Congress on Sulfide Corrosion in Wastewater Collection and Treatment Systems.
• Conducting odor emission surveys and evaluating odor control alternatives for waste treatment facilities from 0.5 to 200 mgd in over 50 cities throughout the U.S., Canada, and abroad.
• Designing and providing design assistance on odor control systems in Keene, NH, Cromwell, CT, Portland, ME, Concord, NH, Fitchburg, MA, and Singapore., and elsewhere.
• Preparing, as principal author, EPA handbooks on 1) Control of Hydrogen Sulfide Corrosion in Wastewater Systems, 2) Control of Odors from Small Sludge Composting Systems, and 3) Septage Treatment and Disposal.
• Preparing, as principal author, the EPA Design Manual on Phosphorus Control.

During his tenure with EPA's Municipal Environmental Research Laboratory, Mr. Bowker's experience included the following:

• Developing the highly-acclaimed EPA Process Design Manual on Onsite Treatment and Disposal Systems.
