Lessons Learned in Laboratory and Field Evaluation of Accelerated Strength Tests for Quality Control of Concrete Pavements
This paper describes the results of an accelerated strength testing program performed to evaluate flexural strength potential at 28- and 90-days. Based upon a literature review of previous...
Hydrogeology Comes to the Surface
Before concluding whether groundwater is safe or contaminated, engineers must understand the science of hydrogeology. If they don't understand hydrogeology, unnecessary and...
Jet Grouting for Underpinning and Excavation Support
Jet Grouting as a new tool for underpinning and excavation support is presented, describing the systems of Jet Grouting and its advantages over conventional underpinning techniques. A...
Case Histories of Shallow Foundations on Improved Soil
Case histories for four projects, with structures varying from a 27-story high rise to a one-story shopping center, are presented. For each of these projects, improving the soil to allow...
Cost Effective Pile Foundation Supports Fast Track Paper Mill
This paper decribes the generalized subsurface conditions, pile evaluation and load test program, pile and piling contractor selection, production pile installation, and quality assurance...
Hydrobiological Characterization of Guanabara Bay
Guanabara Bay forms an ecological unity with serious environmental problems derived from an accelerated and unorganized process of urbanization without the necessary support. The UFRJ/Institute...
Management of Fisheries in the State of Rio De Janeiro, Brazil
To improve the interdisciplinary knowledge and to subdivide the problem in bio-ecological sectors, international committees recommend the development of integrated evaluation groups. On...
POU/POE Devices: Availability, Performance, and Cost
In order to gather and summarize information and data on point of use/point of entry (POU/POE) devices, a committee was established by the Environmental Engineering Division of the American...
POU/POE Water Treatment: Regulatory Challenge
During the past few years the use of point-of-use (POU) and point-of-entry POE) water treatment devices has grown dramatically. One attendant consequence has been the proliferation of...
Use of POE/POU Technology at US Army Installations
A wide spectrum of adverse water quality characteristics has been experienced at US Army installations throughout the country. These characteristics, both interim and long-term in nature,...
Point-of-Entry/Point-of-Use Water Treatment-? Where Do We Go From Here?
The development and marketing of point-of-entry-entry/point-of-use (POE/POU) devices has become a multi-million dollar business, and is projected to become even larger with the annual...
Radon Entry & Control Versus Indoor Dynamics
The measurements of air infiltration, interzonal transport and exfiltration as the diagnostic procedures have been significantly influential in the selection, implementation and evaluation...
Technical Issues Related to Emission Releases from Subslab Radon Mitigation Systems
Surveys of government and private sector radon mitigation activities indicate that subslab radon mitigation systems account for more than 50 percent of all installed systems. Such systems...
Pre-Treatment Process Control of a Variable Quality Raw Water Supply
The West Coast Regional Water Supply Authority is the public agency charged with the development of public water supply for the Tampa Bay Area in the state of Florida. The Authority's...
Study of Direct Potable Reuse of Reclaimed Wastewater: Preliminary Results
