Mercury-free methods for determination of heavy metals in boiler feed, drinking, and sea water samples. Stripping voltammetry uses electrochemical sensors for the determination of heavy metal ions in different types of samples. These can include boiler feed water, drinking ...
Haloacetic acids (HAAs) are commonly produced as disinfection byproducts (DBPs) from water treatment processes. Some HAAs are regulated by the author- ities and have been classified as potentially carcino- genic. They have traditionally been analyzed by gas chromatography (GC), a technique that requires time-consuming sample extraction and derivatiza- tion, leading to higher costs per analysis. ...
Analyzing different types of water samples on a regular basis presents several challenges for analysts. Depending on the type of lab (e.g., municipal or water bottling facilities), the number of samples to be analyzed can vary significantly. Every day such laboratories receive hundreds of samples that must go through pH, conductivity, and alkalinity testing, among others. If additional tests ...

The Société des établissements de plein air du Québec’s (SÉPAQ) key mandate is to manage and develop public spaces along with regional tourism facilities. Its mission is to make sure they are readily accessible to the public, developed in a conscientious manner and to provide protection ensuring best in class facilities for the public, the Province of ...
Owned by the city of Porvoo, the Porvoo vesi is a public utility that delivers water for households and businesses for consumption and also receiving and cleaning wastewater. Although the plant began operating in 1913 many upgrades have occurred making it one of the most technologically advanced and environmentally friendly plants in the region. The number of people the plant now serves has ...
University of Guelph The departments of Engineering and Environmental Sciences at the University of Guelph have used our ColiPlate™ water testing system in numerous graduate level research projects. These projects have included research on bacterial transport in hydrologic systems, projects evaluating the impact of septic systems on ground and surface ...
The Australian Drinking Water Guidelines (ADWG) were developed to provide regulations that ensure drinking water safety. ...
More needs to be done by the municipal water suppliers to minimize Legionella bacteria in the drinking water supply before it can enter building water systems. ...
Jayasumana provided Dr. Gunatilake with rice, drinking water, and urine samples that were subsequently analyzed in the lab. Results found that drinking water was contaminated with glyphosate and heavy metals, and that these compounds were making their way to workers kidneys. Evidence shows that glyphosate bonds ...
Abstract US EPA Method 524.2 was used to determine the concentration of volatile organic compounds (VOCs) in drinking water. The Teledyne Tekmar Lumin purge and trap (P&T) concentrator, along with an AQUATek LVA (liquid vial autosampler) and Agilent 7890B GC/5977A MS was used to create a working linear calibration curve and method detection limits (MDLs) for ...
Abstract The implementation of dual reticulation systems for returning recycled water to the home for nonpotable use is now common in new Australian housing developments. Managing the associated public health risk requires consideration of the potential for crossconnections between recycled and potable water pipes. While current protocols for detection exist, they are time consuming and ...
Under instructions of the Sri Lankan Ministry of Irrigation and Water Resources Management, Royal Eijkelkamp will start this month in various regions of the South Asian country with the realisation of a groundwater monitoring network. ...
This study compares the performance of a novel most probable number (MPN) method (Legiolert™/Quanti-Tray®) with Standard Methods for the Examination of Water and Wastewater 9260 J for the enumeration of Legionella pneumophila from potable and nonpotable waters. Data from the study showed that Legiolert exhibited higher sensitivity for the detection of L. pneumophila for potable water and ...
The aim of this work was to assess the suitability of matrix-assisted laser desorption/ionization–time of flight mass spectrometry (MALDI-TOF MS) for routine heterotrophic monitoring in a drinking water treatment plant. Water samples were collected from raw surface water and after different treatments during ...
A new rapid, sensitive and selective method for rotavirus detection in water samples is described in this paper. Amino pink magnetic microparticles were functionalized with monoclonal antibodies and used to capture, concentrate, separate and detect infectious rotavirus particles in distilled and drinking water ...
ECH-based polymer pipes are widely employed in the production of drinking water. Due to its extreme reactivity and toxicity, many nations have begun imposing limits on the amount of ECH allowable in drinking water. Drinking water analysis of Volatile Organic Compounds (VOCs) is normally ...
For example, after examining data from more than 36,000 water samples collected nationwide by the U.S. Environmental Protection Agency from 2013 to 2015, Harvard researchers found unsafe levels of toxic chemicals in the drinking water of 33 states. In 2016, a USA Today Investigation reported that after analyzing ...
Natural radioactivity and radon concentration were studied in drinking water samples from Baling area, Kedah, Malaysia, using HPGe and RAD-7 detectors, respectively. ...
Southwest Giza area is one of the most complicated regions in Egypt because of the combination of agricultural, industrial and urbanization activities with few studies about water resources contamination with heavy metals. In this study, ten surface water samples and eight groundwater samples were collected and analyzed for ...
