    in water regulation and policy The overall report is divided into three volumes Volume 2 and 3 are detailed reports of the two major phases of the study Volume 2 evaluates the relationship among green building practices green building rating systems and water resource sustainability The evaluation is based on case studies of three diverse commercial green building projects Volume 3 explores what is known as the new paradigm for water resource management at the community level This paradigm is built around the concept of water resource sustainability Volume 3 is based on a workshop that reviewed the water management practices and strategies of two very different communities This volume Volume 1 summarizes the other two volumes as well as two meetings of the advisory committee to the overall study This body of work illuminates the need to work across current boundaries to achieve the most sustainable outcomes As illustrated by the green building case studies the outcomes for a project are better when driven by local water priority issues rather than by a green building rating system based on universal criteria Likewise more sustainable approaches to water management at the local level can be achieved when the plan includes stakeholders involved with all facets of water supply use treatment stormwater management Oftentimes the best approaches are contradictory to one or more existing regulations codes rules or rating systems that do not take into account new technologies and practices and limitations on water availability As many of the current approaches to water management become unsustainable it is becoming increasingly important to look for innovative solutions that may be drastically different than the current management paradigm To truly implement best practices it is critical to bring together all stakeholders and to develop integrated approaches Implementation of sustainable approaches may require more

    fate of graywater chemical and microbiological constituents and the effect of these constituents on plant health after graywater is applied for irrigation The objective of this research project is to elucidate information on the fate and occurrence of graywater constituents and their potential impacts on soil quality groundwater quality and plant and human health as a result of its application for residential landscape irrigation Phase 1 of the project a literature review and synthesis was completed in March 2006 and is available from WERF The final report contains a comprehensive synthesis of the current state of the knowledge on graywater reuse for landscape irrigation at the household level The report also identifies information gaps for future research a number of which are being addressed through Phase 2 Phase 2 began in May 2008 and includes a series of experimental studies The Phase 2 experimental studies are being conducted in three parts existing household systems new household systems and greenhouse studies First soil samples were collected from several household sites that used graywater for irrigation for more than five years and compared with analogous soil and landscaping that had been irrigated with potable water The second part of the study targets new applications of graywater to several selected sites the sites may be new construction or retrofits to newer homes that already have landscaping in place These sites are being operated in a controlled manner for one to two years to determine the dynamics of changes to soil and plant health that might occur due to graywater irrigation and the risk to human health in new systems In addition to the field studies a greenhouse experiment is being conducted The goal of the greenhouse studies is to evaluate in a scientifically controlled environment the toxicity potential of graywater irrigation to annual
