Journal ArticleDOI
A Geochemical Approach to Determine Sources and Movement of Saline Groundwater in a Coastal Aquifer
TL;DR: The analysis of multiple chemical and isotopic tracers indicates that the sources and movement of saline groundwater in the San Diego coastal aquifer are dominated by recharge of local precipitation in relatively shallow parts of the flow system; regional flow of recharge of higher-elevation precipitation along deep flow paths that freshen a previously saline aquifer.
Journal ArticleDOI
Influence of organic carbon loading, sediment associated metal oxide content and sediment grain size distributions upon Cryptosporidium parvum removal during riverbank filtration operations, Sonoma County, CA
TL;DR: Although the grain-surface metal oxides were found to have a high colloid-removal capacity, this study suggested that any major changes within the watershed that would result in long-term alterations in either the quantity and (or) the character of the river's DOC could alter the effectiveness of pathogen removal during RBF operations.
Journal ArticleDOI
Use of Carboxylated Microspheres to Assess Transport Potential of Cryptosporidium parvum Oocysts at the Russian River Water Supply Facility, Sonoma County, California
David W. Metge,Ronald W. Harvey,Robert Anders,Donald O. Rosenberry,Donald Seymour,Jay Jasperse +5 more
TL;DR: Carboxylated microspheres were employed as surrogates to assess the transport potential of Cryptosporidium parvumoocysts during forced and natural-gradient tests conducted in July and October 2004.
Journal ArticleDOI
Effects of sediment-associated extractable metals, degree of sediment grain sorting, and dissolved organic carbon upon Cryptosporidium parvum removal and transport within riverbank filtration sediments, Sonoma County, California.
David W. Metge,Ronald W. Harvey,George R. Aiken,Robert Anders,George Lincoln,Jay Jasperse,Mary C. Hill +6 more
TL;DR: This study suggests that in evaluating the efficacy of RBF operations to remove oocysts, it may be necessary to consider not only the geochemical nature and size distribution of the sediment grains, but also the degrees of sediment sorting and the concentration, reactivity, and penetration of the source water DOC.
ReportDOI
Geohydrology, water quality, and nitrogen geochemistry in the saturated and unsaturated zones beneath various land uses, Riverside and San Bernardino counties, California, 1991-93
Terry F. Rees,Daniel J. Bright,Ronald G. Fay,Allen H. Christensen,Robert Anders,Brian S. Baharie,Michael Land +6 more
TL;DR: In this article, the authors present a survey of the state-of-the-art tools and techniques used in the development of the HOGA algorithm and its application in the field of artificial intelligence.
