Radon Contamination Of Residences In A City Built Upon A Karst Landscape Bowling Green, Warren County, Kentucky, James William Webster

Masters Theses & Specialist Projects

The United States Environmental Protection Agency (EPA) estimates that 8 to 12% of U.S. homes have radon concentrations that equal or exceed 4 picocuries per liter (pCi/l). A statewide screening of Kentucky by EPA resulted in an average residential radon concentration of 2.8 pCi/l with 17% of the homes at or above 4 pCi/l. EPA requires routine monitoring and maintenance or worker health records in mines and caves having radon daughter concentrations at or above 0.30 working levels (WL).

Bowling Green is a city located in a karst region of south central Kentucky. Residents of Bowling Green have been subjected …

Pitzer Faculty Publications and Research

A hunger fast, dubbed Fast Action, was staged in front of the Japanese Consulate General in Honolulu on July 20 to protest the destruction of the most ancient and biologically diverse ecosystem on Earth. Organized by Hawai'i Earth First! and the O'ahu Rainforest Action Group, Fast Action was designed to alert people to the destruction of tropical rainforests in Sarawak, Malaysia. Protesters demanded on immediate moratorium on the cutting of rainforests in,which the Penan and other-native peoples live.

Hawaii's Hottest Issue: Update On Geothermal Development, Paul Faulstich

Pitzer Faculty Publications and Research

Walking through Hawai'i's Wao Kele O Puna rainforest, you can hear the coarse volcanic soil crunch underfoot. A surrealistic calm lingers in the thick air while songbirds call out from the understory. Yet this is a forest under siege.

Geothermal developers want to tap the volcanic heat beneath the Wao Kele O Puna forest and use it to make electricity and profits.

Factors Affecting Wood Fuel Consumption And Environmental Impacts In Warren County, Kentucky, Barry Vann

Masters Theses & Specialist Projects

The purpose of this research is to identify factors that contribute to wood fuel consumption as a space heating source and estimate a county-wide proportion for wood fuel consuming households. In addition, environmental problems associated with deforestation such as erosion and loss of wildlife habitat are delineated; moreover, air pollution resulting from wood fuel emissions are discussed.

An exhaustive literature review provided the basis for the study. Data on Warren County wood fuel consumption patterns were derived from a mail survey. Proportion estimates were tested by using a classical two-tail test of hypothesis. Subsequently, factors were identified and used in …

Moving the West's Water to New Uses: Winners and Losers will be the theme for this year's water conference, June 6-8 at the Law School in Boulder. The conference will consider the changing demands for water in the West and the need to reallocate a portion of the existing uses of water to new uses.

The first day will provide the background by looking at the most likely sources of water to meet these demands, including agriculture, federal water projects, interstate transfers, and …

Enhancement And Monitoring Of The Procambarus Clarkii Population In Lake Mead, Mikell Beth Hager

Publications (WR)

Procambarus clarkii are found in extremely low numbers throughout Lake Mead, AZ-NV. The crayfish are an important dietary component for game fish. Enhancement of the crayfish population would broaden the fishery forage base. Crayfish were stocked and monitored in a study cove on Saddle Island to determine if the Procambarus clarkii population could be enhanced. A trapping survey of the area after the following reproductive season yielded low numbers of crayfish. A comparison of pre-stocking and post-stocking catch per trap day (CPTD) values revealed no significant increase in the population. Procambarus clarkii growth is limited by environmental factors in Lake …

The demonstration drew over 1500 protesters,

A “Drastic” Evaluation Of The Ground-Water Pollution Potential Of Karst Terrain: Lost River Ground-Water Basin, Warren County, Kentucky, David Baize

Masters Theses & Specialist Projects

Karst terrains, such as the Lost River Karst Ground-Water Basin, are extremely vulnerable to ground-water contamination. Seven physical factors: depth to water, recharge, aquifer media, soil media, topography, impact of the vadose zone, and hydraulic conductivity, are evaluated using the DRASTIC system to determine the ground-water pollution potential of the study area. A numerical value is calculated for each of the seven factors, and a map layer for each factor is produced. These layers are then “added” together to produce a DRASTIC ground-water pollution potential map. The effectiveness of each factor in evaluating the pollution potential of karst terrain is …

Warfarin Resistance Of Rattus Tiomanicus In Oil Palms In Malaysia And The Associated Increase Of Rattus Diardii, B.J. Wood, G.F. Chung

Proceedings of the Fourteenth Vertebrate Pest Conference 1990

Rattus tiomanicus is a serious pest of oil palm plantations in Peninsular Malaysia, feeding on the ripening fruit. R. diardii is a rat of human habitations and has been only an occasional field species, presumably because it cannot compete with better adapted species. A widely used control for R. tiomanicus of proven effectiveness uses maize-based baits containing warfarin at 0.05% in 2 cm3 (14.5 g) wax-bound cubes. These are applied in campaigns at one per palm, replaced on 4 daily rounds, until acceptance has declined to 20%. This "standard method" is applied at about 6-month intervals, and rat populations remain …

Politics And Economics Of Maintaining Pesticide Registrations, Kathleen A. Fagerstone, Roger W. Bullard, Craig A. Ramey

Proceedings of the Fourteenth Vertebrate Pest Conference 1990

The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) was amended in 1988 to require the reregistration of all pesticides registered before 1984 within 9 years. The FIFRA 88 required that all pesticide active ingredients must meet current registration standards, suspended the previous fee structure, and imposed a one-time registration fee and annual maintenance fees. New data generated because of FIFRA 88 must conform to EPA's Good Laboratory Practice Standards and animal studies must follow guidelines of the Animal Welfare Act. FIFRA 88 has significantly increased data requirements, data costs, and other pesticide registration and reregistration costs for most pesticides. The …

The Effect Of Seed Coat Colour And Depth Of Planting On Bushfowl Damage To Planted Maize Seeds, Modupe Akande, A.O. Obajimi

Proceedings of the Fourteenth Vertebrate Pest Conference 1990

The bushfowl (Francolinus bicalcaratus bicalcaratus L.) is a major avian pest on planted maize seeds. Maize seeds colored green and normal white seeds were planted at different depths of 2.5 cm, 5.0 cm, 7.5 cm, 10.0 cm, 12.5 cm, and 15.0 cm in three different trials between 1987 and 1988. The effect of planting depth was highly significant. Damage occurring to seeds planted at a depth of 2.5 cm was significantly higher than all the other depths, even though there was not significant damage among the other depths.

Closing Remarks For The Fourteenth Vertebrate Pest Conference, John E. Borrecco

Proceedings of the Fourteenth Vertebrate Pest Conference 1990

This concludes the 14th Vertebrate Pest Conference. Before my closing remarks, let us acknowledge the excellent job done by our session chairpersons and speakers.

For your information, we had 345 people registered at the conference, representing 37 states and 11 other countries.

I first attended the Vertebrate Pest Conference some 14 years ago at the 7th Conference. At that time I was impressed with the breadth of subjects presented, the international scope, the professional exchange of information, and the opportunity to meet noted experts in vertebrate pest control. Since that meeting, I have always looked forward to the next conference …

Native Heteromyid Rodents As Pests Of Commercial Jojoba, Rex O. Baker

Proceedings of the Fourteenth Vertebrate Pest Conference 1990

After crop losses of 5 to 60% were noted on two 500-acre Jojoba (Simmondsia chinensis) plantings in a desert area of southern California, a study was conducted to identify the animals responsible. Various population census and pestidentification techniques were utilized. Four native rodents of the Heteromyid family, not previously known to be pests of Jojoba, were found to be present in sufficiently high numbers to cause severe economic crop loss. The Bailey's pocket mouse (Perognathus baileyi) was the only rodent previously known to survive on Jojoba beans as a food source. A natural chemical, cyanogenic glucoside, …

Effect Of Artificial Perches And Nests In Attracting Raptors To Orchards, Leonard R. Askham

Proceedings of the Fourteenth Vertebrate Pest Conference 1990

Artificial perches and nest boxes were placed in three Pacific Northwest orchards to assess their effectiveness in attracting birds of prey to reduce vole populations. The data indicated that birds could be attracted under some conditions, but vole populations were not significantly affected. Additional factors such as vegetative biomass and human activity may limit their usefulness in reducing rodent populations under intensive agricultural conditions.

Animal Damage Problems And Control Activities On National Forest System Lands, John E. Borrecco, Hugh C. Black

Proceedings of the Fourteenth Vertebrate Pest Conference 1990

A questionnaire survey of the National Forests in 1988 indicated that animal damage control (ADC) was conducted on 208,000 acres of reforestation and older stands, nearly all in the West, at a cost of about $9 million. Sixty-two percent of the total acreage treated, or 128,600 acres, and 49 percent of the ADC costs, or $4.3 million, was in the Pacific Northwest Region (Oregon and Washington). Most of the forests in all regions of the Forest Service, except Alaska, rated animal damage to reforestation and older stands as very important or moderately important. One-third of the forests rated damage as …
