The quality of natural and induced storm runoff was ascertained from the 11.33 x 10^6 m^2 (2800 acre) Honolulu International Airport (daily average air traffic volume of about 1000 planes and a mean annual rainfall of approximately 508 mm [20...

DBCP (dibromochloropropane) has been used as a soil fumigant for nematode control for decades by the Hawaii pineapple industry. Recent detection (parts-per-trillion range) of the fumigant in potable well water has spurred a study of the behavior...

The quality of natural and induced storm water runoff from several smaller public airports in Hawaii (air traffic volume of approximately 130 to over 350 airplanes/day) was compared to results from the previous Phase I study of the Honolulu...

The mCP medium devised by Bisson and Cabelli in 1979 was used to recover Clostridium perfringens from sewage and streams. This membrane filtration method proved to be uncomplicated and reliable. Of 98 presumptively positive colonies recovered from...

Most economists advocate full compensation for natural resource use and for personal injury. The intent of these positions is to assure proper resource allocation and equity. However, this advocacy often neglects nonmarket resources and...

Wastewater disposal into injection wells almost inevitably results in aquifer clogging and reduced injection capacity. In Hawaii, clogging has produced well overflows resulting in numerous public health, legal, and financial problems. Near-well...

Intensive stream surveys were conducted on Maui and Kauai in Hawaiian island streams during October 1979 through 1982 to investigate whether the presence of predaceous eleotrids in terminal reaches of low-gradient streams excluded the rare goby,...

The purpose of the 1981 to 1983 monitoring program at the Barbers Point Outfall on Oahu, is two-fold: to describe the benthic community by utilizing micromollusks as index species and to establish a data base for continuing community analysis....
