Mediation of Metal Element Partitioning in Urban Runoff by Entrained Solids

Reflections on the Regulatory Reform Debate

Leachate Chemistry: Its Implications for Clogging
The clogging of leachate collection systems is controlled by interrelated mi and chemical phenomena. Mesocosms containing landfill materials and simulating leachate collection were infiltrated...

Soil Water Chemistry of Irrigation with Drainwater
The use of drainwater for irrigation was demonstrated as a management option that reduces net farm drainage and provides control over water quality (O'Brien and Guitjens,...

Effects of Hydraulic Gradients on Pore Fluid Chemistry

The Role of Cation Exchange in Controlling Groundwater Chemistry at Äspö, Sweden

Coupling Between Water Chemistry and Thermal Output at Unsaturated Repositories

The Urge to Merge
A report issued in 1994 by the Professional Services Management Association offers a glimpse into the world of mergers and acquisitions in the architecture/engineering industry, through...

The Chemistry of MDF Materials

Arsenic Removal Via Softening
The removal of arsenic during softening was investigated using synthetic solutions. Arsenic removal is facilitated by formation of a variety of solids including Mg(OH)2,...

Assessment of BNR Systems in Florida
Operating data from eight, full-scale, single-sludge, biological nutrient removal (BNR) wastewater treatment facilities in Florida were collected and evaluated. Three types of BNR facilities...

Arsenic Removal by Manganese Greensand Filters
Some of the small communities in Saskatchewan are expected to have difficulty complying with the new maximum acceptable concentration (MAC) of 25 μg/L for arsenic. A test column was set...

Quantification of the Mechanisms Controlling the Removal Rate of Volatile Contaminants by Air Sparging
Air sparging is a technology for removing dissolved and volatile phase chemicals (VOCs) from the saturated zone. It is used in conjunction with soil vapor extraction (SVE) and sometimes...

NOAA, Bioassessment Techniques and the Superfund Process
The National Oceanic and Atmospheric Administration's (NOAA) assessments of SUperfund sites require an evaluation of whether contaminants are present in an aquatic environment of concern,...

TM Bands' Remote Measure Test for Seawater's Multi-factors—First Step Research on Remote Sensing for Bay's Self-Purificability
Marine Remote Sensing is different from Land Remote Sensing in someways, one of which is that ocean is a 3-d fluid with large changes in time and space. So the field sampling in sea-water,...

Pond Water, Sediment and Crystal Chemistry
The chemistry of pond waters is characterized with respect to TDS, major solute species and trace elements. Similar chemical characteristics are presented for pond bottom sediments as...

Permanence of Grouted Sands Exposed to Various Water Chemistries

The Potential Use of Genetically Engineered Microorganisms in the Remediation of Environmental Pollution
Naturally occurring microorganisms express a broad range of metabolic activities which are being successfully applied to the field of bioremediation. Genetic engineering will enhance such...

Magnetic Fluid Conditioning
Industry is now turning to develop magnetic water treatment in an effort to discontinue the use of chemicals. Magnetic water treatment takes a different approach to solving the same problem...

Effects of Uranium Mining, Puerco River, New Mexico
Effluent from uranium-mine dewatering and acidic water released by a tailings-pond dike failure increased radionuclide activities in streamflow in the Puerco River in New Mexico and Arizona....
