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

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,...

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...

The Chemistry of MDF Materials

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

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....

History of Lysimeter Design and Use for Evapotranspiration Measurements
Lysimeters are devices for measuring percolation of water through soils and sampling soil water for chemical analyses. Lysimeters have been used for over 300 years to determine water use...
