Abstract:
A sensory gas chromatography (sensory GC) procedure with appropriate quality assurance steps was developed to evaluate ng/l concentrations of odorous chemicals in drinking water. Closed loop stripping analysis was used to concentrate the chemicals in the water samples. Sensory GC analysis was completed by smelling the effluent at the exit port of an on-column injector capillary GC system. An identical and parallel GC flame ionization detector system was used to monitor the sensory gas chromatograms. The sensory GC analysis is important because it can detect some of the individual components of the odor that a sensory panel determines on a water sample. The relationship between sensory panel response and the sensory GC procedure were investigated near threshold odor concentration levels and the data shows that sensory GC does not always correlate with sensory panel evaluations. This can be caused by the concentrations differences of the chemicals in the mixture and synergistic and antagonistic effects. Two taste and odor events reported at the Baxter Water Treatment Plant of the city of Philadelphia on the Delaware river were investigated. The events were first a metallic aftertaste accompanied by a burnt rubber odor and second a cucumber odor in the drinking water. The cases studied illustrate the use of FPA, sensory GC and GC/MS to understand the chemical nature of the odors present in the samples.

Abstract:
Abstract Short-chain carbonyls could cause taste and odor issues in drinking water due to their very low odour threshold concentrations (OTCs). Several techniques such as 2,4-dinitrophenylhydrazine (DNPH) derivatization-HPLC and solid-phase micro-extraction (SPME) have been applied for trace short-chain aldehydes analysis in water. However, to study the taste and odor contributors in drinking water, it would be helpful to obtain an extract with representative odor from water samples for further studies, such as GC-olfactometry analysis or sensory test. Therefore, the above techniques still have some constraints due to the derivatization process or complex operating procedures. In this work, we developed a solid-phase extraction (SPE) coupled to dispersive liquid–liquid micro-extraction (DLLME) method to study short-chain aldehydes in ozonated water samples (LOQ = 1 ppb, RSD% = 12–45%). This method enables us to obtain an extract with representative odor from water for further volatile components analysis and sensory evaluation. Pair-wise nose clip sensory evaluation on the taste and odor of ozonated water indicated a high correlation between odor and taste of ozonated water. The SPE-DLLME method enabled a reliable study, for the first time, on correlations of volatile carbonyls and taste & odor performance for ozonated water by applying a series of statistical models.

Abstract:
Earthy and musty odours are amongst the most frequently observed objectionable odours in water supplies, and geosmin and 2-methylisoborneol are identified as the chemical compounds most closely associated with these odours. In this paper, the sensory properties, and the water matrix effects on taste and odour panel studies, as well as the chemical analysis methods for earthy and musty odours in drinking water caused by geosmin and 2-methylisoborneol, are reviewed. Insights are developed to enable better evaluation of earthy and musty odours in drinking water. Early detection of geosmin and MIB can prevent off-flavour occurrence by providing information for potential treatment.

Abstract:
In the majority of the European Community, the assessment of odours and flavours in water supplies are carried out only by sensory analysis. Consequently it is essential for institutes and water companies to use the most accurate method in evaluating odour and flavour in drinking water. Until recently, most of the European countries had their own method or national Standard. Due to the requirements for odour and flavour in EC Directive 80/778 on drinking water quality, applicable throughout Europe, there was a need to standardise their method of evaluation. At the time, no ISO Standard for flavour and odour existed. Moreover, since the materials intended for contact with drinking water must not induce organoleptic problems, manufacturers of pipes, fittings and coatings are also concerned in a standardization. This paper presents the state of the art for flavour and odour evaluation in European countries and the next European Standard for these parameters. The Standard will be based on the dilution method to obtain a threshold flavour number (TFN) and a threshold odour number (TON) of a water. The principle is to compare the successive dilutions of water samples with a reference water. Several methods can be used, for example paired and triangle test, forced and unforced choice. The Standard also includes the selection, training and calibration of panellists. This Standard was elaborated within the scope of CEN/TC 230 “Water Analysis”, and was achieved through the active participation of experts from water institutes, water companies and manufacturers of materials.

Abstract:
The cause(s) of many taste and odor problems in drinking water remain unknown. If sufficient information about the problem is not available to develop a hypothesis, one can begin to develop a hypothesis to test by using correlation methods from data base information concerning the problem. This paper presents a method to develop a correlation between chemicals and sensory characteristics of.a set of water samples by Principal Component Factor Analysis. The correlations developed hypotheses for the causes of tastes and odors that must be further tested. A correlation indicates that a pattern is occurring between two data bases. In this case, the pattern is a change of a Chromatographie peak's detector response which parallels the sensory response of a flavor profile analysis panel for an organoleptic descriptor. The correlation must always be confirmed by sensory analysis. The results from an application of the method to data from the city of Philadelphia Water Department and Philadelphia Suburban Water Co. are shown. An evaluation of the results is described. The correlation between a sensory response and a chemical concentration in water was described by expanding the Weber-Fechner Law. The Weber-Fechner Law states that the odor intensity of a sensory descriptor is proportional to the logarithm of the concentration of the chemical associated with the odor. Two drinking water data sets from the Philadelphia Water Department and Philadelphia Suburban Water Co. were used to demonstrate the sensory-chemical correlation procedure. Correlations were observed. Clearly, a correlation indicates a possible relationship, a “presumptive result” that must be tested by sensory analysis to “confirm” if the relationship is true. A correlation indicates that a pattern is occurring between two data bases. In this case, the pattern is a change of a Chromatographie peak's detector response which parallels the sensory response of a flavor profile analysis panel for an organoleptic descriptor. The correlation must always be confirmed by sensory analysis as stated by the rules of scientific evidence.

Abstract:
The standards that establish water’s quality criteria for human consumption include organoleptic analysis. These analyses are performed by taste panels that are not available to all water supply companies with the required frequency. In this work, we propose the use of an electronic tongue to perform organoleptic tests in drinking water. The aim is to automate the whole process of these tests, making them more economical, simple, and accessible. The system is composed by an array of electrochemical microsensors and chemometric tools for multivariable processing to extract the useful chemical information. The array of sensors is composed of six Ion-Sensitive Field Effect Transistors (ISFET)-based sensors, one conductivity sensor, one redox potential sensor, and two amperometric electrodes, one gold microelectrode for chlorine detection, and one nanocomposite planar electrode for sensing electrochemical oxygen demand. A previous study addressed to classify water samples according to taste/smell descriptors (sweet, acidic, salty, bitter, medicinal, chlorinous, mouldy, and earthy) was performed. A second study comparing the results of two organoleptic tests (hedonic evaluation and ranking test) with the electronic tongue, using Partial Least Squares regression, was conducted. The results show that the proposed electronic tongue is capable of analyzing water samples according to their organoleptic characteristics, which can be used as an alternative method to the taste panel.

Abstract:
A task of water supply systems is to provide safe drinking water to every customer, which is a basic human need. Aging of water supply networks and increased precaution of terrorism risks led to re-evaluation of drinking water supply system reliability and vulnerability to accidental and intentional contamination. Contamination of drinking water can cause health, social, psychological and economic issues. During the last decade, early warning systems (EWS) were often used to ensure the safety of drinking water. EWS are driven by conventional sets of drinking water quality sensors, and the collected data are analyzed in real time. For detection of contamination events, numbers of algorithms have been developed. Most of the algorithms are based on statistical analysis or machine learning. The aim of this study was to compare existing methods and to identify the method, which is suitable for contamination detection in drinking water from non-compound specific sensors and requires relatively low computational resource. A detailed review of 11 different algorithms was presented in the current study with the primary focus on detection probability. Cluster analysis in combination with Mahalanobis distances of feature vectors and Canonical correlation analysis (CCA) approach were selected as the most promising methods for application in a new generation of EWS to detect and classify possible contamination events and agents. While canonical correlation analysis method was the most accurate for detection of contamination events, an advantage of Mahalanobis distances was that it not only detects the contamination events but also could identify the type of contaminant. In this study, we conclude that CCA and Mahalanobis distance methods might be applied for detection of contamination events with relatively high and reliable precision.

Abstract:
As the bottled water trend continues to rise across the nation, drinking water utilities have become more concerned with ensuring consumer satisfaction of their product. Although public water supplies are safeguarded by regulations, aesthetically unappealing taste-and-odor problems have led consumers to search for alternative water sources, such as bottled water or tap water processed by point-of-use filters. Consequently, taste-and-odor monitoring has become important to the drinking water industry. Because many utilities use chlorine to disinfect the water, chlorine odor often masks other more subtle odors that may eventually cause consumer complaints. As treated water travels from the water treatment plant to the consumer, chlorine residual diminishes and may reveal a water's naturally less-pleasing odors. Consequently, odor monitoring at the water treatment plant, where chlorine concentrations are at a peak, may not identify potential displeasing smells. Proper evaluation of these odor-causing substances requires that the chlorine odor first be eliminated before evaluating any remaining odors. Dechlorinating agents can remove chlorine, but some will produce other unwanted odors or even remove certain odorous compounds. This research describes the efficiency of several of these agents (ascorbic acid, hydrogen peroxide, oxalic acid, sodium nitrite, and sodium thiosulfate) in dechlorinating chlorinated solutions of the earthy-smelling compound geosmin and musty-smelling MIB. Interfering odors in reusable containers pose another problem in drinking water odor analysis. The most common odor-analysis methods (TON and FPA) involve the use of glass flasks, which often either develop chalky odors or have persistent lingering odors from previous evaluations. Furthermore the glass flasks break easily and are difficult to clean. This research also evaluates the suitability of four types of disposable plastic containers for odor analyses.

Abstract:
In recent years, communities that source raw water from the Dan River experienced two severe and unprecedented outbreaks of unpleasant tastes and odors in their drinking water. During both TandO events strong 'earthy', 'musty' odors were reported, but the source was not identified. The first TandO event began in early February, 2015 and coincided with an algal bloom in the Dan River. The algal bloom was thought to be the cause, but after the bloom dissipated, odors persisted until May 2015. The second TandO in October, 2015 did not coincide with observed algal blooms. On February 2, 2014 approximately 39,000 tons of coal ash from a Duke Energy coal ash pond was spilled into the Dan River near Eden, NC. As there were no documented TandO events before the spill, there is concern the coal ash adversely impacted water quality and biological communities in the Dan River leading to the TandO events. In addition to the coal ash spill, years of industrial and agricultural activity in the Dan River area may have contributed to the TandO events. The purpose of this research was to elucidate causes of the two TandO events and provide guidance to prevent future problems. Monthly water samples were collected from August, 2016 to September, 2017 from twelve sites along the Dan and Smith Rivers. Multivariate analyses were applied to look for underlying factors, spatial or temporal trends in the data. There were no reported TandO events during the project but sensory analysis, Flavor Profile Analysis, characterized earthy/musty odors present. No temporal or spatial trends of odors were observed. Seven earthy/musty odorants commonly associated with TandO events were detected. Odor intensity was mainly driven by geosmin, but no relationship between strong odors and odorants was observed.

Abstract:
Implications of water chemistry on milk synthesis are not well described yet water is an important nutrient for dairy cattle. High mineral concentrations (>0.3 mg/kg Fe and others) may be associated with natural levels in ground water, contaminating sources, drought conditions, or storage systems. This study evaluated effects of added iron in bovine drinking water on milk composition (Ca, Cu, Fe, P) measured by inductively coupled plasma mass spectrometry and oxidative stability measured by thiobarbituric acid reactive substances assay for malondialdehyde (MDA), volatile chemistry and sensory analysis (triangle test). Prepared ferrous lactate treatments, corresponding to 0, 2, 5, and 12.5 mg/kg drinking water levels were given abomasally (10 L/d) to 4 lactating dairy cows over 4 periods (1 wk infusion/period) in a Latin square design. Milk was collected (d6 of infusion), processed (homogenized, pasteurized), and analyzed within 72 h of processing and 7 d of refrigerated storage. No differences in MDA (1.46�0.04 mg/kg) or iron (0.22�0.01 mg/kg) were observed in processed milk. Cross effects analysis (treatment*cow) showed significant differences in calcium, copper and iron (P < 0.05). Sensory differences (P < 0.05), in treatment vs. control, suggested iron from water sources contributes to milk flavor changes. A case study with high and low (0.99; 0.014 mg/kg) iron treatments revealed no significant differences (P > 0.05) in mineral composition (0.23�0.06 mg/kg Fe) or MDA (0.77�0.03 mg/kg) of raw milk. Iron added to milk causes changes in oxidation; high levels of iron in bovine drinking water may not have observed effects.

Good water quality is very central to a country's wellbeing. Clean water is required to ensureboth the health of the population and good ecological status of the country. It is thereforeimportant to continually conduct surveys to determine the status of the water used in, forexample, households, industries and agriculture.Elevated levels of metals, sulphate, nitrate and phosphate in drinking water can lead to poorhealth through consumption and reduced harvest when the water is used in irrigation.This report aimed at examining whether the water resources available in the vicinity of Njuliquarry in Chiradzulo, Malawi, meet the requirements of drinking and irrigation water. Thestudy found that most of the studied parameters were within the recommendations set by theMalawi Bureau of Standards (MBS) and the World Health Organization (WHO). However,conductivity in some of the water samples was higher than the recommendations. Both nitrateand iron concentrations were higher than recommended at a few locations.The study cannot conclude that the water from the water sources near the Njuli quarry containharmful levels of metals, nitrate, sulfate or phosphate.

Abstract:
The distribution system is the primary cause of taste and odor complaints in drinking water. This research examined the ability of small diameter pipes used in home plumbing to affect drinking water quality. The properties of the materials were investigated in the absence of disinfectant and the presence of either chlorine or chloramines. A panel was trained in flavor profile analysis (FPA) according to Standard Methods 2170B and used to assess the sensory properties of all samples. Chemical analyses were performed to determine disinfectants, total organic carbon (TOC), pH and specific organic contaminants. The first part of this study investigated PEX pipes manufactured by the silane (PEX-b) and peroxide (PEX-a) cross-linking technology, using the utility quick test (UQT) method. Silane PEX-b had a greater effect on water quality properties such as odor, TOC and residual disinfectant demand than peroxide-linked PEX-a. Chemical analysis revealed that PEX pipes can contribute fuel oxygenates such as ETBE (PEX-b) and possibly MTBE (PEX-a) to drinking water. PEX pipes did not contribute any significant trihalomethanes to drinking water. This study showed that the type of PEX used in homes will determine the extent to which drinking water quality is affected. The second part of this study used simulated plumbing rigs to investigate seven different materials under low flow and stagnant conditions; chlorinated polyvinyl chloride, cross-linked polyethylene, polyethylene, epoxy-lined copper, copper, stainless steel, galvanized iron and glass (control). Results showed that these plumbing materials have the potential to affect water quality characteristics such as TOC concentrations, residual disinfectant and odor when newly installed in homes. A high TOC concentration was consistent with the presence of a distinct odor or a high FPA intensity rating. Galvanized iron produced the worst odors that were consistently described as "motor oil". Polyethylene generated more intense plumbing associated odors than PEX or cPVC plastic material. cPVC and copper generated the least odors. Both copper pipe and epoxy-lined copper consumed residual chlorine and chloramines.

Abstract:
A methodology has been developed and used to evaluate the alternatives to chlorination for primary and residual drinking water disinfection. From the evaluation process it was concluded that at present none of the altemalives could viably replace chlorination for both primary and residual disinfection. The study did however highlight the potential of electrochemical disinfection technologies to provide primary and residual disinfection in the future by the generation of a range of oxidants including chlorine species. Hence, three electrochemical technologies (a mixed oxidant generator, a direct electrolyser with carbon aerogel electrodes, and a direct electrolyser called Zappi ™ )were chosen to assess their potential as an alternative to conventional chlorination for primary and residual disinfection. The disinfection efficiencies of the three devices were assessed. Anolyte produced from the mixed oxidant generator was compared directly with hypochlorite at equal doses. Anolyte was shown be more effective against E. coli, reducing the E. coli count by >6 logs and to have the same potential for trihalomethane formation in slow sand filtered water, generating 30).μg/L when dosed at lmg/L for 24 hours. The carbon aerogel and Zappi™ direct electrolysers were shown to disinfect E. coli in a range of electrolytes and water matrices. Total measurable E. coli log reductions were achieved in both devices using a chloride electrolyte. Significantly, both devices were effective against E. coli in sulphate electrolytes without the generation of chlorine, with 3 and 4 log reductions respectively. The carbon aerogel device was also shown to be effective in a good quality sewage effluent matrix and tap water reducing E. coli by >4 logs. Whilst, the Zappi was shown to reduce E. coli by >2 logs in slow sand filtered water. Phosphate was shown to significantly reduce disinfection in both direct devices. The effectiveness of the direct electrolysers was shown to be variable against other micro-organisms. The Zappi™ device was effective against the virus, bacteriophage MS2 in a sulphate electrolyte, with a >5 log inactivation after 30 minutes. Whilst, the carbon aerogel device achieved a > 1 Jog reduction of Enterovirus after 40 minutes in tap water and a 2 log reduction of Cryptosporidium oocysts in tap water. It should be noted that the reduction in Cryplosporidium could be attributable to removal via filtering rather than inactivation by oxidant attack. Possible mechanisms for electrochemical disinfection were investigated of these oxidant generation was shown t~ be responsible for disinfection_ Determination of the oxidant species generated proved to be problematic. The presence of chlorine and the high voltages used in all three devices made it difficult to isolate specific oxidants. The bactericidal properties of two poly-viologens were assessed 10 determine their potential for mediating oxidant generation for drinking water disinfection. The poly-viologens were shown to reduce the E. coli count by 6 logs. However, the results were inconclusive due to the variability between poly-viologen batches. These studies do however infer that poly-viologens may still have a future use as oxidant mediators in disinfection devices.

Abstract:
Exposure to excess manganese via drinking water raises concerns due to potential for adverse neurological impacts, particularly in children. Manganese is ubiquitous in US groundwaters above the SMCL = 0.05 mg/L. Manganese is an essential nutrient, but exposures to elevated manganese have neurotoxic effects. Chapter 2 focuses on human senses\' ability to detect manganese in drinking water. Findings indicate human senses cannot be relied upon to detect excess Mn(II) in drinking water. Mn(IV) is easily visually detected, but cannot be tasted at 10 times the SMCL. Chapter 3 is an assessment the ability of an ultrasonic humidifier to expel drinking water impurities in aerosols. The quality of the water used to charge the humidifier reservoir affects the composition of elements in the aerosols and condensate. Findings indicate condensed humidifier aerosols contain 85% of elements present in the reservoir water for a variety of water types if there is no precipitation. Waters with high concentration of hardness or iron formed precipitates that decreased the concentrations of these metals in the aerosols causing variable results for other elements that were initially present at < 1mg/L in the charge water. This indicates that humidifiers could be a source of inhalation exposure for source water contaminants.

Abstract:
For water suppliers, using chlorine is necessary to ensure water bacteriological quality from the treatment plant to the consumers' tap. However, chlorine flavour is one of the most common reasons advocated for choosing tap water alternatives as drinking water. As a consequence, the putative link between chlorine flavour perception and tap water consumption is an issue in drinking water habits studies. Since the sensory mechanisms involved in chlorine flavour perception remained largely unknown, the main objective of this thesis work was to first highlight those mechanisms and then to identify potential lever chlorine flavour sensory neutralisation.In a first step, we demonstrated that hypochlorous acid associated, which is likelyresponsible of chlorine flavour in tap water, could activate the olfactory system at low concentrations and the trigeminal system for concentrations up to 4 mg/L Cl2. Additionally, our results suggested that tap water consumption does not seem to be related to sensitivity to chlorine flavour but rather to consumers' tap water representation.In a second stage, we explored the impact of water mineral matrix on chlorine flavour perception. We demonstrated first that water molarity and cationic content variations modulate drinking water taste. We also evidenced that chlorine flavour intensity is modulated according to water composition. Nevertheless, our data suggest that physico-chemical, in- mouth physiological and sensory mechanisms are likely involved in such modulation.In the last part of the Thesis work, we investigate the putative influence of aroma perceptionon chlorine flavour. Our results showed that beyond chemical reactions between hypochlorous acid and odorants, aromas at peri-threshold concentration enhance chlorine flavour and decrease tap water acceptability

Abstract:
Access to safe drinking water is a fundamental right of people. The West Bengal Drinking Water Sector Improvement Project is assisting the Government of West Bengal to provide safe, sustainable, and inclusive drinking water services to over 1.65 million people in the arsenic, fluoride, and salinity-affected areas of Bankura, North and South 24 Parganas, and Purba Medinipur districts. This publication sets the baseline of the project by providing the benchmark comparison of primary outcomes for the project and non-project households, before implementation, so that an impact evaluation can be carried out at project completion.
