Assessing Bioavailability of Metals in Biosolids-Treated Soils
Plant-availability of metals in biosolids-treated soils may be mathematically described by Mt = C x [1 - e- (k x t)] where Mt (mg kg-1) is the...
Sensor Technology for Water Quality Monitoring
The main objective of this project is to demonstrate that the technology of on line monitoring of waterborne metals by X-ray Fluorescence (XRF) at part per billion (ppb) and sub-ppb levels, which...
Safe Drinking Water
Drinking water provides an efficient source for the spread of gastrointestinal microbial pathogens capable of causing serious human disease.
The massive death toll and burden of disease...
Visual Hydrology
One approach to the introduction of computational material to the classroom is to supplement a textbook with modern computer codes. Unfortunately most codes are expensive, designed for commercial...
Organic Compounds and Genotoxicity in Drinking Water
Until recently only lipophilic compounds were analysed in any research on the occurrence of mutanogenic and carcinogenic compounds in water. They were isolated using XAD-resins. They contain...
Scaling Propensity of Water
The commonly used Saturation Index calculated at 10°C (SI10) is not suitable for practical situations. New parameters have been developed for simple and rapid analysis of calcium...
Development of Practical Methods to Assess the Presence of Bacterial Pathogens in Water
The objective of this project was to develop and evaluate a practical technique to indicate the probability of the presence of bacterial pathogens in receiving waters. A practical method was...
Case Studies of Modified Treatment Practices for Disinfection By-product Control
Utilities must decide whether to modify their existing treatment practices to achieve compliance with the D/DBP regulations. A regulatory impact analysis predicted that up to 70% of large surface-...
Chemical Occurrence Data Sets for Source Water Assessments
This research project aims to identify, list, and characterize chemical occurrence databases and data sets that can be used by states and utilities to perform source water assessments. The data...
Cyanide Formation and Fate in Complex Effluents and its Relation to Water Quality Criteria
Cyanide occurs in many industrial and municipal wastewaters and is often an expected constituent of typical treatment plant wastewater streams. However, a growing number of wastewater treatment...
