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

Coupling Between Water Chemistry and Thermal Output at Unsaturated Repositories

Water Chemistry of Lead Corrosion Control
Requirements of the Lead and Copper Rule (U.S. EPA) makes it necessary for regulators, consultants, and water purveyors to understand the fundamental relationships between water quality...

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...

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...

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,...

The Chemistry of MDF Materials

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

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...

Products of Chloramination in Dilute Aqueous Solution
Chloride and nitrate formation was determined in the reaction of chlorine with ammonia in molar excess, in dilute aqueous solution. Nitrate was formed under all conditions investigated....

Air-Water Transfer: The Role of Partitioning
A review is presented of the role of air-water equilibrium in determining the direction and rate of transfer of chemicals between water bodies and the atmosphere. Because this diffusive...

Effects of Water Composition on the Dissolution Rate of UO2 Under Oxidizing Conditions
Dissolution rates were measured on crushed unirradiated UO2 fuel pellet samples under oxidizing conditions using a flow-through testing method. Water...
