Governance Challenges

Small drinking water systems (SDWS) are widely identified as presenting particular challenges for drinking water management and governance in industrialised nations because of their small customer base, geographic isolation, and limited human and financial capacity. Consequently, an increasing number and range of scholars have examined SDWS over the last 30 years. Much of this work has been technocentric in nature, focused on SDWS technologies and operations, with limited attention to how these systems are managed, governed, and situated within broader social and political–economic contexts. This review seeks to provide a comprehensive overview of the governance dimensions of SDWS by drawing together existing literature relating to SDWS governance and exploring its key themes, research foci, and emerging directions. This overview is intended to provide guidance to scholars and practitioners interested in specific aspects of SDWS governance and a baseline against which researchers can position future work. The review identified 117 academic articles published in English-language journals between 1990 and 2016 that referred to some aspect of drinking water governance in small, rural, and Indigenous communities in industrialised nations. The articles’ content and bibliographic information were analysed to identify the locations, methods, journals, and themes included in research on SDWS governance. Further analysis of SDWS’ governance dimensions is organised around four questions identified as central to SDWS research: what governance challenges are experienced by SDWS, and what are their causes, solutions, and effects? Overall, the review revealed that the SDWS governance literature is piecemeal and fragmented, with few attempts to theorise SDWS governance or to engage in interdisciplinary, cross-jurisdictional conversations. The majority of articles examine North American SDWS, retain a technocratic orientation to drinking water governance, and are published in technical or industry journals. Such research tends to focus on the governance challenges SDWS face and proposed solutions to systems’ performance, capacity, and regulatory challenges. A small but growing number of studies examine the causal factors underpinning these governance challenges and their socio-spatially differentiated impacts on communities. Looking forward, the review argues for a more holistic, integrative approach to research on SDWS governance, building on a water governance framework.

The occurrence of trihalomethanes (THMs) was studied in the drinking water samples from urban water supply network of Karachi city that served more than 18 million people. Drinking water samples were collected from 58 locations in summer (May-August) and winter (November-February) seasons. The major constituent of THMs detected was chloroform in winter (92.34%) and summer (93.07%), while the other THMs determined at lower concentrations. Summer and winter concentrations of total THMs at places exceed the levels regulated by UEPA (80 μg l-1) and WHO (100 μg l-1). GIS linked temporal variability in two seasons showed significantly higher median concentration (2.5%-23.06%) of THMs compared to winter.

Individual Risk

Many Indigenous communities across Canada suffer from the lack of access to clean drinking water; ensuring individuals and communities have safe water to drink either from their home or from their local environment requires the consideration of multiple factors including individual risk perception. In collaboration with local leaders, semi-structured interviews (n = 99) were conducted over a two-year period in the Dene Tha’ First Nation and Kátł’odeeche First Nation to unpack the issue of risk perception and its meaning to local community members. These local metrics of risk perception including smell, taste, safety, health fears and level of concern were then used to explore patterns in other data on drinking water consumption patterns and bottled water use. The results are consistent with previous research related to water insecurity and indicate that both communities consume more bottled water than the average Canadian. Results also varied by jurisdiction; those in Alberta indicated much higher levels of concern and a greater degree of bottled water consumption.

State Of The Science

The United States Environmental Protection Agency mandates that community water systems (CWSs), or drinking water utilities, provide annual consumer confidence reports (CCRs) reporting on water quality, compliance with regulations, source water, and consumer education. While certain report formats are prescribed, there are no criteria ensuring that consumers understand messages in these reports. To assess clarity of message, trained raters evaluated a national sample of 30 CCRs using the Centers for Disease Control Clear Communication Index (Index) indices: (1) Main Message/Call to Action; (2) Language; (3) Information Design; (4) State of the Science; (5) Behavioral Recommendations; (6) Numbers; and (7) Risk. Communication materials are considered qualifying if they achieve a 90% Index score. Overall mean score across CCRs was 50 ± 14% and none scored 90% or higher. CCRs did not differ significantly by water system size. State of the Science (3 ± 15%) and Behavioral Recommendations (77 ± 36%) indices were the lowest and highest, respectively. Only 63% of CCRs explicitly stated if the water was safe to drink according to federal and state standards and regulations. None of the CCRs had passing Index scores, signaling that CWSs are not effectively communicating with their consumers; thus, the Index can serve as an evaluation tool for CCR effectiveness and a guide to improve water quality communications.

Effect Of Treatment

Abstract Mass medication to manage population health can be achieved by providing therapeutics in the drinking water. Young nursery pigs are highly sensitive to the flavor and smell of water. Medications that reduce water palatability often lead to an interruption in water and feed intake. With the availability of several generic water-soluble antimicrobials for pigs, questions have arisen about their palatability compared with the original product. In this study, we compared the intake of water containing tiamulin hydrogen fumarate from two different manufacturers with the intake of unmedicated water. The hypothesis was that the intake of tiamulin-containing water would be similar to unmedicated water. Water intake was monitored upon entry into the nursery and just prior to leaving the nursery. Also, average daily gain (ADG) and feed efficiency (FE) were determined. A total of 300 pigs were individually weighed (4.2–10.9 kg; avg = 6.8 kg) for randomization to pen (n = 30 pens). The experiment had two time points: 1) early nursery (periods 1–3) and 2) late nursery (period 4). Pens were randomly assigned to a sequence (period 1–3) in a crossover experimental design containing three 10-d periods, with 5 d for the resetting of baseline where unmedicated water was provided followed by 5 d on tiamulin source addition [i.e., TriamuloxTM (Zoetis, Parsippany, NJ); Denagard (Elanco Animal Health, Greenfield, IN)] or unmedicated water. After period 3 was concluded, all pens were given unmedicated water (via nipple waterers) and the number of pigs per pen was reduced to six pigs to maintain adequate space per pig. Ten days prior to pigs leaving the nursery, a fourth period was performed. After a 5-d water baseline was achieved, pens were treated with either unmedicated water or Triamulox- or Denagard-containing water. Pigs had ad libitum access to water and feed. During the testing periods, daily water intake was measured by a cup water system in each pen. Feed intake was measured every 5 d. There was no effect of treatment on initial body weights or weights at the beginning or end of each period (P ≥ 0.51). Therefore, there was no effect of treatment on ADG (P ≥ 0.23). Water intake (P ≥ 0.16) and FE (P ≥ 0.35) were not affected by treatment. Water consumption was similar among all treatments in each of the four periods. There appears to be no aversion to water intake when tiamulin hydrogen fumarate is added to the drinking water.

Water governance refers to the material and regulatory control of water and waters. It involves questions such as who makes decisions about water and how; at what scale such decisions are made in relation to different waters; and who and which water or ecosystem benefits. Classical work in anthropology considered how irrigation practices may have given rise to the development of state forms, and in response to early-21st-century privatization regimes, anthropologists have considered how different groups have challenged the apparent global dominance of commodity values and water as property. Infrastructures for water distribution in urban areas (such as systems of canals, pipes, and faucets), and considerations of the sociocultural effects of hydrological unit delineation and definition (e.g., groundwater or river “basins”) have become key sites for the ethnographic investigation of water governance, emerging forms of personhood, and societal inequalities. The diversity in anthropologies of water unsettles generalized models in global regimes of water governance. The anthropology of water governance and ownership considers the context and contingencies of water and power. It reveals the global dominance of markets, rights, and technical approaches to water management, such as the case of “private water” in Chile, in which water markets have failed to provide equity and environmental health, but also how certain groups avoided complete privatization of water under this extreme example. Ethnographic studies of the cultural organization of resource scarcity over topographically complex and remote terrain, such as that of irrigators in the Andean cordillera, express the diversity of human innovation at the intersection of politics and ecology. In arid South Eastern Australia, basin plans that treat water as a unit of calculation and economic trade place social and ecological relations in peril. Infrastructures of development provide a narrative of unsettled state and development ideologies, and the problem of groundwater management reveals governance challenges in the face of unstable, unknown, and invisible material. Anthropological studies of water contribute to knowledge of earth’s diverse humanity, knowledge practices, and ecologies. Researchers propose that water governance might engage with human differences articulated at multiple scales, as well as in understanding water’s material agency and waters as dynamic, especially in an ever-changing climate.

The composition and microbial community structure of the drinking water system biofilms were investigated using microstructure analysis and 454 pyrosequencing technique in Xiamen city, southeast of China. SEM (scanning electron microscope) results showed different features of biofilm morphology in different fields of PVC pipe. Extracellular matrix material and sparse populations of bacteria (mainly rod-shaped and coccoid) were observed. CLSM (confocal laser scanning microscope) revealed different distributions of attached cells, extracellular proteins,α-polysaccharides, andβ-polysaccharides. The biofilms had complex bacterial compositions. Differences in bacteria diversity and composition from different tap materials and ages were observed. Proteobacteria was the common and predominant group in all biofilms samples. Some potential pathogens (Legionellales, Enterobacteriales, Chromatiales, and Pseudomonadales) and corrosive microorganisms were also found in the biofilms. This study provides the information of characterization and visualization of the drinking water biofilms matrix, as well as the microbial community structure and opportunistic pathogens occurrence.
