Book Description
This research examined the microbiological quality of drinking water distribution systems typically encountered in First Nation in Canada. Fecal bacteria and a wide range of antibiotic resistance genes (ARGs) were frequently present in tap water of a community that relies on lake water as the source water to its water treatment plant, whereas this was not the case in communities that rely on groundwater. Fecal bacteria and ARGs were predominantly detected in tap water of homes that had water distributed by a truck for storage in underground cisterns, and not in treated water of homes with piped water. Cistern samples that tested positive for fecal bacteria had free residual chlorine concentrations less than 0.2 mg/L, which is required to suppress microbial growth. We are urging all governments in Canada to strategize how to alternatively deliver clean, running drinking water to families living in these homes.

Book Description
This study determined the microbiological quality of drinking water from various water distribution systems of two First Nation communities in Manitoba, Canada. E. coli, other coliforms as well as different types of antibiotic resistance genes (ARGs) were more often detected in water from homes with cisterns than homes with the direct-lined piped system. Cistern water showed the presence of bacteria, as well as ARGs, and had free chlorine concentrations less than the World Health Organization (WHO) standard recommended level that is 0.2 mg/L. Also, environmental changes affect the fecal bacterial counts as warmer months showed higher counts than the colder months. Moreover, this study also showed the presence of mecA gene carrying Mammaliicoccus fleurettii in lake water which is used as source water and recreational purposes in a First Nation community in Manitoba, Canada. Our study suggests that both drinking water and recreational water should be monitored for taking further steps to protect the community residents' health from waterborne illness.

Book Description
"The report, 'Make It Safe: Canada's Obligation to End the First Nations Water Crisis,' documents the impacts of serious and prolonged drinking water and sanitation problems for thousands of indigenous people--known as "First Nations"--living on reserves. It assesses why there are problems with safe water and sanitation on reserves, including a lack of binding water quality regulations, erratic and insufficient funding, faulty or sub-standard infrastructure, and degraded source waters. The federal government's own audits over two decades show a pattern of overpromising and underperforming on water and sanitation for reserves"--Publisher's description.

Book Description
Approximately 50% of the homes on First Nation reserves in Manitoba, Canada, receive piped water from water treatment plants (WTP). Of the remaining homes, 31% are equipped with cisterns filled by a water truck. The overall objective of this thesis research was to compare the quality of tap water in homes with piped water versus those with cisterns. The study was in collaboration with three First Nations communities in Manitoba. Each community was predominantly equipped with belowground concrete cisterns, belowground fibreglass cisterns, or aboveground polyethylene cisterns stored in insulated shelters. Free residual chlorine concentration was significantly lower in water samples from homes with cisterns than piped water. The frequency and severity of Escherichia coli and total coliform contamination were significantly greater in drinking water from belowground concrete and fibreglass cisterns than in piped water samples in each community. The contamination of belowground cisterns by coliform bacteria was greatest in late spring. Data obtained under the Access to Information Act for 2014 and 2018 showed no clear evidence of improved water quality in any of the Tribal Councils linked to the three communities. Field and laboratory chlorine disappearance studies indicated a greater contribution of concrete cistern walls than bulk water to the disappearance, hence lowering free residual chlorine concentration in belowground cisterns. Treated water from the WTP in two of the First Nations communities frequently exceeded the Health Canada guideline of 100 μg L-1 total trihalomethanes (TTHMs), as did 75% of piped water samples and 70% of cistern water samples. Although the water distribution system had no significant effect on TTHM concentration, sampling month significantly affected due to temporal changes in source water dissolved organic carbon content. Dissolved organic carbon removal before further water treatment might be an important process in effectively reducing TTHMs formation, and thereby decreasing the exposure of residents to high levels of TTHMs. Additional treatment at household level, regular cleaning, and maintenance of belowground concrete and fibreglass cisterns are important to reduce the risk of water-borne illnesses. Also, belowground cisterns must be replaced with aboveground cisterns to reduce coliform contamination, although piped water is the preferred option.

Book Description
Indigenous research is an important and burgeoning field of study. With the Truth and Reconciliation Commission’s call for the Indigenization of higher education and growing interest within academic institutions, scholars are exploring research methodologies that are centred in or emerge from Indigenous worldviews, epistemologies, and ontology. This new edited collection moves beyond asking what Indigenous research is and examines how Indigenous approaches to research are carried out in practice. Contributors share their personal experiences of conducting Indigenous research within the academy in collaboration with their communities and with guidance from Elders and other traditional knowledge keepers. Their stories are linked to current discussions and debates, and their unique journeys reflect the diversity of Indigenous languages, knowledges, and approaches to inquiry. Indigenous Research: Theories, Practices, and Relationships is essential reading for students in Indigenous studies programs, as well as for those studying research methodology in education, health sociology, anthropology, and history. It offers vital and timely guidance on the use of Indigenous research methods as a movement toward reconciliation.

Book Description
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 worldwide caused by unsafe drinking water is a compelling reason to value the privilege of having safe drinking water delivered to individual homes. On rare occasions, that privilege has been undermined in affluent nations by waterborne disease outbreaks traced to the water supply. Using the rich and detailed perspectives offered by the evidence and reports from the Canadian public inquiries into the Walkerton (2000) and North Battleford (2001) outbreaks to develop templates for understanding their key dimensions, over 60 waterborne outbreaks from 15 affluent countries over the past 30 years are explored as individual case studies. Recurring themes and patterns are revealed and the critical human dimensions are highlighted suggesting insights for more effective and more individualized preventive strategies, personnel training, management, and regulatory control. Safe Drinking Water aims to raise understanding and awareness of those factors that have most commonly contributed to or caused drinking-water-transmitted disease outbreaks - essentially a case-history analysis within the multi-barrier framework. It contains detailed analysis of the failures underlying drinking-water-transmitted disease epidemics that have been documented in the open literature, by public inquiry, in investigation reports, in surveillance databases and other reliable information sources. The book adopts a theme of 'converting hindsight into foresight', to inform drinking-water and health professionals including operators, managers, engineers, chemists and microbiologists, regulators, as well as undergraduates and graduates at specialty level. Key Features: Contains details and perspectives of major outbreaks not widely known or understood beyond those directly involved in the investigations. Technical and scientific background associated with case studies is offered in an accessible summary form. Does not require specialist training or experience to comprehend the details of the numerous outbreaks reviewed. By providing a broad-spectrum review using a consistent approach, several key recurring themes are revealed that offer insights for developing localized, tailor-made prevention strategies.

Book Description
Centuries-old community planning practices in Indigenous communities in Canada, the United States, New Zealand, and Australia have, in modern times, been eclipsed by ill-suited western approaches, mostly derived from colonial and neo-colonial traditions. Since planning outcomes have failed to reflect the rights and interests of Indigenous people, attempts to reclaim planning have become a priority for many Indigenous nations throughout the world. In Reclaiming Indigenous Planning, scholars and practitioners connect the past and present to facilitate better planning for the future. With examples from the Canadian Arctic to the Australian desert, and the cities, towns, reserves and reservations in between, contributors engage topics including Indigenous mobilization and resistance, awareness-raising and seven-generations visioning, Indigenous participation in community planning processes, and forms of governance. Relying on case studies and personal narratives, these essays emphasize the critical need for Indigenous communities to reclaim control of the political, socio-cultural, and economic agendas that shape their lives. The first book to bring Indigenous and non-Indigenous authors together across continents, Reclaiming Indigenous Planning shows how urban and rural communities around the world are reformulating planning practices that incorporate traditional knowledge, cultural identity, and stewardship over land and resources. Contributors include Robert Adkins (Community and Economic Development Consultant, USA), Chris Andersen (Alberta), Giovanni Attili (La Sapienza), Aaron Aubin (Dillon Consulting), Shaun Awatere (Landcare Research, New Zealand), Yale Belanger (Lethbridge), Keith Chaulk (Memorial), Stephen Cornell (Arizona), Sherrie Cross (Macquarie), Kim Doohan (Native Title and Resource Claims Consultant, Australia), Kerri Jo Fortier (Simpcw First Nation), Bethany Haalboom (Victoria University, New Zealand), Lisa Hardess (Hardess Planning Inc.), Garth Harmsworth (Landcare Research, New Zealand), Sharon Hausam (Pueblo of Laguna), Michael Hibbard (Oregon), Richard Howitt (Macquarie), Ted Jojola (New Mexico), Tanira Kingi (AgResearch, New Zealand), Marcus Lane (Griffith), Rebecca Lawrence (Umea), Gaim Lunkapis (Malaysia Sabah), Laura Mannell (Planning Consultant, Canada), Hirini Matunga (Lincoln University, New Zealand), Deborah McGregor (Toronto), Oscar Montes de Oca (AgResearch, New Zealand), Samantha Muller (Flinders), David Natcher (Saskatchewan), Frank Palermo (Dalhousie), Robert Patrick (Saskatchewan), Craig Pauling (Te Runanga o Ngai Tahu), Kurt Peters (Oregon State), Libby Porter (Monash), Andrea Procter (Memorial), Sarah Prout (Combined Universities Centre for Rural Health, Australia), Catherine Robinson (Commonwealth Scientific and Industrial Research Organization, Australia), Shadrach Rolleston (Planning Consultant, New Zealand), Leonie Sandercock (British Columbia), Crispin Smith (Planning Consultant, Canada), Sandie Suchet-Pearson (Macquarie), Siri Veland (Brown), Ryan Walker (Saskatchewan), Liz Wedderburn (AgResearch, New Zealand).
