The Water Resources Research Center at the University of Hawaii at Manoa in cooperation with the Virgin Islands Water Resources Research Institute, the Puerto Rico Water Resources and Environmental Research Institute, and the Water and Environmental Research Institute of the Western Pacific in Guam organized a conference on the general theme of water and wastewater sustainability issues in island environments. These four centers (along with 50 others in the continental United States) operate under the US Geological Survey’s Water Resources Research Institute Program to address problems and issues of water and wastewater management that affect our regions with programs of targeted research.
As a service to the community of individuals concerned with water and solute flow in Hawaii the Water Resources Research Center at the University of Hawaii offered a workshop on advanced modeling of water flow and contaminant transport in porous media using the HYDRUS and HP1 software packages.
U.S. recreational water quality criteria (RWQC) are needed to protect the public health of people who swim and bathe in designated beaches. However, advances in microbiology, environmental science and engineering, and epidemiology, as well as progress in monitoring programs in the last decades have called into question the scientific credibility of the RWQC. Hence in 2000, the U.S. Congress (the Clean Water Act as amended by the BEACH Act) mandated USEPA to conduct studies concerning pathogen indicators in recreational waters and to review the criteria. USEPA responded with several epidemiological studies, as well as organized a series of scientific and stakeholder workshops to learn about relevant issues to be considered in the development of new or revised criteria.
