(Water Resources Research Center, University of Hawaii at Manoa, 1982-01)Natural streams collect runoff and discharges from many sources which alter the quality of stream water. To determine the hygienic quality of streams, water samples from streams are collected and assayed for two human ...
-
(Water Resources Research Center, University of Hawaii, 1983-01)Phase 2 of this project represents the analytical monitoring of an estimated 64,800 ft^3 (1,835 m^3) of chromium-contaminated soil, classified as a hazardous waste (>5 mg/l chromium extract concentration as measured ...

(Water Resources Research Center, University of Hawaii at Manoa, 1983-05)The primary purpose for the analysis of the Haina Well water by the Water Resources Research Center of the University of Hawaii at Manoa was to determine the presence or absence of human enteric viruses in the well water. ...
-
(Water Resources Research Center, University of Hawaii at Manoa, 1983-09)Annual maximum rainfall series at 157 gages were used to evaluate extreme value rainfall. Daily fixed-interval data were adjusted by a factor of 1.143 to represent true maxima. Records of short-term stations were extrapolated ...
-
(Water Resources Research Center, University of Hawaii at Manoa, 1984-03)The rotating biological contactor CRBC) is an attached (fixed) growth, biological treatment unit which consists of closely spaced, rotating shaft-mounted discs that generally have approximately 40% of their surface submerged ...
-
(Water Resources Research Center, University of Hawaii at Manoa, 1984-06)Habitat utilization curves were developed for life stages of three species of Hawaiian native stream fishes. The development of such curves is necessary for implementation of the Incremental Flow Instream Methodology (IFIM) ...
-
(Water Resources Research Center, University of Hawaii at Manoa, 1984-12)A desalting test using low pressure, reverse osmosis (RO) FT-30 and FT-50 membranes was conducted on Pump 10 well water at Oahu Sugar Company near Campbell Industrial Park on O'ahu. The brackish test water from the Waianae ...
-
(Water Resources Research Center, University of Hawaii at Manoa, 1985-07)In recent years, various chemical contaminants have been detected in Hawai'i’s groundwater sources. Several agencies in Hawai'i have been monitoring the groundwater quality for the contaminants, dibromochloropropane (DBCP), ...
-
(Water Resources Research Center, University of Hawaii at Manoa, 1985-11)Pesticides applied to pineapple fields in central O'ahu to control nematode populations have been detected in groundwater drawn from the underlying aquifer. These nematicides have persisted in surface soils and deep saprolite ...
-
(Water Resources Research Center, University of Hawaii at Manoa, 1985-11)A reliable and practical method is required to reduce the concentrations of hazardous chemicals (EDB, DBCP, TCP) which have been detected in some of the groundwaters used for drinking on O'ahu. This study evaluates the ...
-
(Water Resources Research Center, University of Hawaii at Manoa, 1985-11)In recent years, several pesticide-related contaminants have been detected in the basal waters of southern and central O'ahu aquifers. Dibromochloropropane (DBCP) and ethylene dibromide (EDB), two soil fumigants which were ...
-
(Water Resources Research Center, University of Hawaii at Manoa, 1985-11)Efforts are being made to identify the sources, concentrations, spatial extent, movements, and rates of degradation of recently detected groundwater contaminants in Hawai'i. A spatially detailed evaluation of the time ...
-
(Water Resources Research Center, University of Hawaii at Manoa, 1985-11)As part of the ongoing research of the WRRC Subsurface Water Quality Project, a drilling program was begun in October 1985 to collect soil and saprolite core samples from sites located in central O‘ahu pineapple fields. ...
-
(Water Resources Research Center, University of Hawaii at Manoa, 1985-12)This progress report is a study of the unprecedented problem of low-level organic chemical contaminants discovered principally in 1983 in potable groundwater sources on O'ahu. A number of inmediate and serious concerns are ...
-
(Water Resources Research Center, University of Hawaii at Manoa, 1986-09)A self-contained pilot unit (including primary and secondary sedimentation) complete with electric motor driven plastic discs (surface area approximately 500 ft2), located at the U.S. Navy's 7.5 mgd Fort Kamehameha Wastewater ...

WRRCSR No.1:15:87 A Virus Monitoring Program for Irrigating Sugarcane with Mililani Sewage Effluent (Water Resources Research Center, University of Hawaii, 1987-01)The City and County of Honolulu (CCH) and the Oahu Sugar Company (OSC) have entered into a long-term agreement to use sewage effluent to irrigate sugar cane. Briefly, the objective of this monitoring program is to establish ...
-
(Water Resources Research Center, University of Hawaii at Manoa, 1987-07)The 'Ewa caprock aquifer has been a long-standing water source for southern Oahu, but the freshwater viability of the aquifer is being threatened with a gradual increase in the salinity level of pumped aquifer water in ...
