A consistent classification and nomenclature of the aquifer systems in the state of Hawaii do not exist in spite of the fact that groundwater is an essential water supply source in each island. The classification of water resources currently in...

Groundwater is the source of 99% of the drinking water provided to consumers on Oahu, the major island in the state of Hawaii. However, virtually all approved sources of water on Oahu have been planned for use. As a result, plans for new urban...

A theoretical function is derived to predict the transient position of the saltwater-freshwater interface set in vertical motion from an initially static equilibrium state. The function is found to be proportional to the square root of time after...

Shallow wells and individual rainwater catchment systems meet the water requirements of many Micronesians. The quality of this water is a matter of public health interest because this region suffers from a high incidence of gastrointestinal...

During the period July 1978 to December 1980, a detailed study of the fresh groundwater resources of Kwajalein Island, Marshall Islands, was conducted. A total of 23 observation wells was constructed to monitor the thickness, areal extent, and...

Many resource planning models have been developed, but few have been implemented. Frequently, months are needed to prepare inputs for a few seconds of analysis. The analysis output again requires weeks of plotting for easy comprehension. Although...

Since its establishment in the spring of 1971 the Hawaii Environmental Simulation Laboratory (HESL) has attempted to simulate some of the consequences of alternative land use-economic decisions. The Kane'ohe region on O'ahu Island, Hawai'i was...

Human enteric viruses were recovered from 0.19 to 0.76 m^3 samples obtained from various natural marine water sites using the portable virus concentrator (Aquella). The concentration and frequency of viruses and coliform bacteria were highest...

Present experience with extended aeration plants in high density resort and suburban developments in Hawai'i has been generally unsatisfactory due to (1) inadequate system management resulting from insufficient manpower resources, and (2) high...

In this memorandum repoTt. an attempt will be made, based on previous and present findings, to predict the changes in the ground-water hydrology as a consequence of the accelerated rate of shift of agricultural lands to urban developments.

Cover series title: Technical Memorandum Report No. 23
1970-06-01
A computerized system for the storage and retrieval of Water Quality data and corresponding stations has been compiled for the Department of Health (DOH), State of Hawaii. Specific data banks include: zones of mixing, waste discharge and effluent,...

Although efforts to include market concepts in the study of water demand appear in the technical literature as early as 1926 (Metcalf, 1926), it was not until 1959 that some of the more difficult conceptual issues relating to economic demand...

The purpose of this study is to determine for watersheds contributing to specified important estuaries in the State of Hawaii, the types and quantities of "agricultural chemicals” (pesticides and fertilizers) applied, the timing of such...

Mill discharge from Kilauea Sugar Company discolors the receiving waters off the north coast of Kauai and increases the turbidity thirtyfold over that for normal waters. Coral growth is abundant in this area except near the mill discharge outfall....

The use of the coliform bacteria as the indicator organism to identify fecal contamination has universal acceptance in the fields of public health and pollution control. However, it is well documented that the interpretation of the results using...
