Research Category: Drinking Water , Water
Objective:
The Center’s overall objectives will focus on applying principles of risk reduction, sustainability and new implementation approaches to innovative technologies that will reduce the risk associated with key contaminant groups and will increase the chance of adoption and sustainable use in small systems.
Progress Summary:
As planned in the proposed schedule, results have primarily been limited in the first year of the Center research to the Project 1 activities that were intended to lead the Projects 2-4 activities. The Project 1 goal “…to develop, refine and disseminate a risk reduction based strategy that will facilitate improvements in the effectiveness and sustainability of small drinking water systems by focusing the implementation of innovative water treatment technologies” has been communicated to a wide range of water community stakeholders including small systems and their technical service providers, state regulators, and technology developers. Their direct feedback has shown support for the need and our approach to deliver our intended field tested multi-criteria decision support approach incorporating risk reduction and sustainability indices. Research activities for Projects 2-4, the technology innovation portion of the Center, are also underway, but limited results to date in the first year of activities. The motivation for tasks in these activities relative to the award goals and Agency mission remain the same as articulated in the proposal. The outputs and outcomes are on schedule to directly address practical small system problems.
Future Activities:
The next year of the project will focus on (a) the refinement and integration of Project 1 activities to develop the multi-criteria decision support approach, (b) collaboration between Project 1 with Projects 2-4, (c) laboratory research to further the development of innovative technologies, and (d) dissemination of results through presentations and publications.
