“…Un aspecto importante en la prevención de las enfermedades virales trasmitidas por agua es la mejoría de la calidad del agua de las cuencas, lo cual disminuye la contaminación de la fuente de agua, los procedimientos de tratamiento y los costos (34). Por lo tanto, deben instaurarse programas para la prevención de contaminantes en las cuencas y, así, preservar la calidad del agua de las fuentes abastecedoras.…”

Introducción. El agua de consumo humano puede ser vehículo de transmisión de agentes patógenos. La detección de virus entéricos en estas muestras de agua es esencial para establecer las acciones adecuadas de control y prevención de las enfermedades asociadas. Objetivo. Analizar los resultados del diagnóstico de virus entéricos en muestras de agua para el consumo humano recibidas en el Instituto Nacional de Salud y establecer su asociación con los datos sobre la calidad del agua en los municipios de Colombia. Materiales y métodos. Se hizo un análisis descriptivo retrospectivo de los resultados obtenidos en la detección de rotavirus, enterovirus, virus de la hepatitis A y adenovirus, en muestras de agua recibidas para estudios complementarios en la investigación de brotes de hepatitis entérica, de enfermedad diarreica aguda y de enfermedades transmitidas por alimentos. Dicha información se correlacionó con los datos de la vigilancia de la calidad del agua municipal determinada según el índice de riesgo de la calidad del agua (IRCA). Resultados. Se procesaron 288 muestras de 102 municipios de Colombia, de las cuales el 50,7 % fue positivo para algún virus: 26,73 %, para el virus de la hepatitis A; 20,48 %, para enterovirus y rotavirus, y 18,05 % para adenovirus. Se detectaron virus en 48,26 % de las muestras de agua no tratada y en 45,83 % de las de agua tratada. El IRCA no mostró correlación con la presencia de virus. Conclusiones. La presencia de virus en el agua representa un riesgo para la salud pública. La prevención de la transmisión de virus por medio del agua requiere políticas para fortalecer los sistemas de suministro y para mejorar la vigilancia epidemiológica.

“…In fact, described water quality dependent on which kind of using. For example, water utilized for irrigation must be completely minimal in dissolved minerals to avoid salination of soils; water for recreation using should reach criteria for fecal coli forms; and potable water must be safe for drinking and cleaning [6][7][8]. Therefore, traditional method of water quality assessment can be described as the analysis of the biological, chemical, and physical properties of water in guide to natural quality, human health impacts, and wanted uses [9,10].…”

“…The source water protection planning in Ontario does not include SDWSs therefore there is no enhanced safety net for these systems. Health risks of consuming water from an unprotected source are considerably high compared to a protected water source (Davies and Mazumder, 2003). The effects of climate change in the region, which include frequent extreme weather events, might put stress on the safety of the water sources.…”

“…A study examining chemicals in water from 6013 private wells over a 12 month-period concluded that over 25% of the wells exceeded the acceptable levels of chemical contaminants (Harrison et al, 2000). Davies and Mazumder (2003) discussed the negative effects of agricultural, industrial and domestic use of chemicals on water sources and advocated for the reduction of their use and environmentally friendly disposal practices to reduce chemical contamination. Our study recommends greater emphasis on monitoring the chemical composition of the source water to confirm drinking water meets the regulatory limits.…”

Sekercioglu et al.: Relationship between operational characteristics of small non-community drinking water systems and adverse water quality incidents in Southern Ontario, Abstract. Ensuring that water sources are safe by protecting them from disease causing organisms is integral for the continued health of people as drinking contaminated water leads to waterborne diseases which can be life-threatening. The purpose of this study is to examine small non-community drinking water systems' (SDWSs) operational characteristics and their relationships with adverse water quality incidents (AWQIs) which is defined as presence of total coliforms and/or Escherichia coli. We explored the relationship between operational characteristics of SDWSs and the occurrence of adverse water quality outcomes using de-identified data provided by Wellington-Dufferin-Guelph Public Health, Ontario. We examined the associations between water system operational characteristics and the adverse water quality outcome using logistic regression models. The analyses results indicated that operator training was associated with a lower risk for AWQI. None of the other predictors were significantly associated with AWQI: treatment method, water source, operating period, or sampling frequency. Our research concluded that the presence of operator training, an upstream behavioural determinant, is related to the incidence of AWQIs in SDWSs in Ontario, Canada. The high percentage of SDWSs with no treatment and lack of interest in testing for chemicals are potential areas of concern for ensuring the provision of safe drinking water from these systems.
