MAppFx is a web page interactive map environment that retrieves an interactive graph of a site upon clicking a map feature object (be it a point, polygon, or a line). WERI Web MAppFx is a product of WERI through the Guam Hydrologic Survey Program (P.L. 24-247) and USGS 104-b, available through the Guam Hydrologic Survey website. MAppFx is developed by GHS Information Management Team Dannika K. U. Valerio, Matt W. Zapata, Leroy F. Heitz, and Nathan C. Habana in collaboration with Brigham Young University Civil Engineering Department Riley Hales, Gus Williams, and Norm Jones.
GHS data analysis of Guam’s production well nitrate-n samples was done by Jezreelyn Y. Bulaklak and Nathan Habana. A Scientific Advisory Report was produced and written by Jezreelyn Bulaklak, Nathan Habana, and John Jenson.
Data originated from Guam Waterworks Authority as organized and transferred through Mauryn McDonald (WERI Technical Report 95), and lab records from Jennifer Cruz, N’tasha Perez, and Carmen Sian-Denton and Gary Denton.
