Sustainable management in your hands
The Guam Hydrologic Survey and Comprehensive Water Monitoring Program (GHS and CWMP), Guam Public Laws 24-247 and 24-161, respectively, were established to develop an inter-agency cooperation for gathering and publicly providing water and environmental information. The ultimate goal is to support our quest of determining sustainable development and management of our island’s most valuable renewable resource, water. The mandate intent is to form a network that will help us improve our understanding of our water resources through data collection, analysis, interpretation, recommendations, reports, and presentation in all efforts to determine its optimum development for sustainable utility. GHS and CWMP contains the island’s collection of water resource and related hydrologic and environmental information by way of an organized online database system. Read more >>

GHS and CWMP Annual Reports
Water and Environmental Research Institute of the Western Pacific (WERI), University of Guam (UOG), is charged with administering the GHS and CWMP. Annual reports are prepared for the years:

GHS and CWMP Program Mission Statement, Goals, Funding
Mission Statement
The Guam Hydrologic Survey (GHS) and the Comprehensive Water Monitoring Program (CWMP) were created in 1998 by the 24th Guam Legislature under Public Laws No. 24-247 and 24-161, respectively. The Water and Environmental Research Institute (WERI) was charged with administering the annual legislative appropriations to drive these two programs and facilitate, direct, and implement their objectives. Both programs are now an integral component of water resources research, information dissemination, education and training on Guam.
Goals
The Guam Hydrologic Survey consolidates and archives new and historical hydrological data collected by local and federal government agencies and private consultants, and conducts research on water-related issues of local importance. GHS also funds a variety of water resource educational programs, including guest lectures and seminars at UOG and in the community, informational and training workshops for teachers and other professionals, field trips and talks for schoolchildren, and the publication and distribution of educational posters, maps, and fact sheets.
The CWMP was created to collect data on saltwater intrusion and water lens thickness in Guam’s northern aquifer, and stream flow for surface waters in the south. The program builds on studies previously undertaken by the US Geological Survey (USGS) that had been abandoned in the 1990s because of a discontinuance of matching funds from the Government of Guam. The CWMP annual appropriations from the Guam legislature restored the program in 1998 and since then have facilitated the collaborative reinstatement of these studies with USGS under their 50-50 Federal/State-Territory cost-sharing program for water resource monitoring.
The foresight of the Guam Legislature in creating these two very important programs deserves special mention here. With the continued support of the Legislature, we now maintain several vital water resources databases for Guam and collect essential water resource data in collaboration with the USGS. Our understanding of the complex physical, chemical and biological processes that influence Guam’s water resources has broadened considerably and the increase in graduate student research opportunities has substantially added to the number of highly trained water resources professionals in the island’s technical work force.
Funding 2018
GHS and CWMP appropriations written into each public law are $204,200 and $173,948 respectively. Local budgetary constraints saw a 6% reduction in funding support for both programs in FY’09, i.e., $192, 309 and $163,817 awarded for GHS and CWMP respectively. These shortfalls continued through FY’12. An additional 5% reduction was levied against each account by Governor Calvo in FY’12 and is continuing through FY’14. This reduces the total awards to $182,694 for GHS and $155,626 for CWMP. The information presented herein summarizes all GHS and CWMP program objectives and related activities undertaken in FY’17.
Cooperators and contributors (GWRDG|TEG)
WERI is also a member of the local water resource interagency organization called the Technical Experts Group (TEG) and the Groundwater Resource Development Group (GWRDG) establish by the 16 July 2010 Memorandum of Understanding between the US Navy and Guam Waterworks Authority (Appendix I). The MOU provides an additional venue for meeting the GHS and CWMP mandates to “establish a direct working relationship with each organization collecting hydrologic data important to Guam, and maintain a permanent flow of new data from each organization to keep the data library up to date.” Local and federal agencies that are party to or affected by the MOU include Guam Waterworks Authority, Guam Environmental Protection Agency, CUC, US Navy (NAVFACMAR), USAF (36 CES), and USGS. Interagency groups also include private consultants: Duenas Camacho and Associates, Allied Pacific Environmental Consultant (APEC), EA Engineering, Brown and Caldwell, and AECOM. Meetings are organized and held quarterly at Guam Waterworks Authority (Gloria B. Nelson Public Service Building), Fadian. Current discussion is the expansion of monitoring (observation) wells, see details in CWMP Research Projects section. The interagency group organization, formed of three groups: executive, working, working group, and the technical team (See the GHS and GWRDG organization chart>>).
The inter-agency group meets quarterly to discuss concerns, pool resources, share ideas, provide update, consult, and gain professional acquaintance and partnerships. Here is a list of agencies in attendance:
