Chloramines: A Better Way?
Chlorination of drinking water has been linked to the formation of carcinogenic trihalomethanes (THMs). By adding ammonia to the water, the chlorine becomes chloramines which don't...

Integration of EPA Guidelines Air Quality Models with Human Exposure/Risk Estimation Procedures
Techniques, based on dispersion models which are currently available, for performing population and maximum individual exposure and risk assessments due to ambient air emissions are described....

Unit Operations Approach in Exposure/Release Evaluation for New Chemicals
The unit operations approach may also be applied to the estimation of potential exposure and release of toxic materials from the manufacture and/or processing of new chemicals. By characterizing...

Health Effects,Risk Assessment and Guidance for Indoor Radon
Unlike many inorganic elements, radionuclides have no nutritional value. Radionuclides are carcinogenic and uranium is also known to be non-carcinogenic as well. This paper is primarily...

Responsibility/Liability Related to Mudflows/Debris Flows
The combined experiences of the authors during the past few decades indicate that many of the problems and losses related to damage from floods, landslides, mud/debris flows, and water-related...

Facilities Planning in the Caribbean a Case Study
Culebra has significant problems of water scarcity and poor wastewater treatment. In 1984-1985, a formal Environmental Impact Statement (EIS) was prepared for improved wastewater treatment...

Ground Water Strategy in California
There is great debate over when and how much new water California needs. Yet of the backbone supply, wells that could serve over 1 million people have been either removed from use or blended...

Policy Issues in Managing Nonpoint Source Pollution
Attention is first given to the extent of the right of the landowner to generate contaminated runoff. The previously recognized privilege of landowners to make point source waste discharges...

Civil Entrepreneuring
Increasing numbers of people are leaving secure, well-paying positions with the government, academia and the private sector to go the risky route of establishing their own firms. The rewards...

Lessons Learned from Design, Construction, and Performance of Hydraulic Structures
The intent of this publication is to provide lessons learned, both positive and negative, from activities associated with design, construction, and performance of hydraulic structures....

Water Project Design and Safety: Prospects for Use of Risk Analysis in Public Sector Organizations
After offering some initial definitions, the authors will describe a highly structured model of risk analysis and water resources decision making in the public sector. The primary emphasis...

Approaches to Acceptable Risk
Acceptable risk has numerous meanings, that are derived from its having been defined in multiple arenas and by multiple groups. This paper describes several approaches to the question...

The Credibility of Probabilities: An Application to Water Resources Policy
This paper focuses on one particularly troublesome issue in decision analysis, the issue of the credibility of subjective probabilities. A water resources policy problem is used to illustrate...

The Metropolitan Boston Area Earthquake Loss Study
This study develops an inventory of critical facilities in the Metropolitan Boston area and analyzes the impact of a project earthquake (Cape Ann Event) on their structural integrity and...

Lifeline Risk Analyses: The Mokelumne Aqueduct Study
Probabilistic risk analysis methods are applied to the evaluation of seismic and non-seismic vulnerability of a 25-kilometer length of a major lifeline aqueduct system. In addition to...
