Water Affordability in the United States: Meaning and Measurement
The ability of low-income families to pay for basic water and sewer services is critical to the success of utility organizations and a subject of increasing public concern. Large-scale assessments of affordability are rare, however, and are limited by poor measurement and biased samples. I use improved metrics and data from an original, representative sample of water and sewer utilities in the United States to evaluate the affordability of basic residential water and sewer service. Results suggest some potentially fruitful avenues for policy development to address affordability.
Manny Teodoro works at the intersection of politics, public policy, and public management. His research focuses mainly on U.S. environmental policy and implementation, including empirical analyses of environmental justice. In addition to academic studies, Professor Teodoro pursues a line of applied research on utility management, policy, and finance. He’s developed novel methods for analyzing utility rate equity and affordability, and works on these issues directly with governments and water sector leaders across the United States.

Opportunities and Challenges to Implementing Non-point Source Nutrient Reduction Practices
The Iowa Nutrient Reduction Strategy Non-Point Source Science Assessment was released in 2013. This review highlighted the range of practices that would be needed and scale of implementation to reach the Gulf of Mexico Hypoxia Task Force Action Plan goals. While the scale of implementation is large and presents many challenges, there are also new opportunities that have the potential to arise as practices are implemented. This could range from diversity of cropping systems to rural economic opportunities in the design and installation of nutrient reduction practices.

Implementing AI Machine-Learning Software for Water Distribution Infrastructure Asset Management
Water infrastructure throughout the US is reaching a critical stage of condition and sustainability. The outlook for water conveyance systems, as recently describes in ASCE's 2017 Report Card, shows a continuing and downward trendline in reliability remaining useful life (RUL) and increasing trendline in asset age and rates of failure. In order to turn this corner and, in particular, establish better and more reliable information on these essential assets, a number of recent advances in prediction models using machine-learning artificial intelligence (AI) combine with robotic, live-main inspection technologies has moved the science of engineering to create better/smarter/faster renewal solutions.

Making EBPR Sustainable and Affordable Using S2EBPR at the Olathe, KS Facility
The City of Olathe began operating its Cedar Creek Wastewater Treatment Facility (WWTF) expansion in 2012. It was the first Black & Veatch design to incorporate sidestream enhanced biological phosphorus removal (S2EBPR), a process discovered by Dr. James Barnard that uses fermentation of mixed liquor by bacteria to support phosphorus removal, rather than adding chemicals. Since the City still operates parallel oxidation ditches that use ferric chloride to remove phosphorus, a side-by-side comparison of operating costs quantifies the affordability and stability of the S2EBPR. Six years of operating data and lessons learned will be discussed.
