“…The significance of actions under this program is notable when considering the operational and structural challenges faced by municipal governments in its development. Thus, an intersectoral approach is crucial, ranging from promoting proper treatment of water for supply to implementing ongoing health educational programs (Bárta et al, 2021). Municipal health departments, therefore, monitor parameters through a basic sampling plan composed of analyses for turbidity, free residual chlorine, fluor, and presence of total coliforms and Escherichia coli.…”

Water is a vital natural resource for the existence of life, maintenance of ecosystems and the development of society. Many cities and communities rely on surface catchment systems, which involve collecting water from rivers, lakes and dams. Others, in turn, use underground collection systems, obtaining water from aquifers and artesian wells. Each of these methods presents specific challenges regarding water quality, as surface water is more exposed to organic and inorganic pollutants, while groundwater may contain minerals and dissolved substances that affect its potability. In general, the quality of water that reaches homes and commercial establishments is determined by the analysis of microbiological indicators, free residual chlorine, turbidity, total coliforms and fluoride. This narrative review seeks to clarify the nuances of water capture systems, their particularities and the factors that affect water quality in Brazil, highlighting the importance of constant monitoring, adequate treatment and effective water management policies in guaranteeing access to fresh water high quality for everyone.

“…This situation is aggravated in socially vulnerable and rural communities (WHO, 2017). In developing countries, such as Brazil, one of the main aggravating factors of these issues is the lack of sewage treatment, resulting in negative consequences due to inadequate disposal of liquid waste into the environment (Bárta et al, 2021).…”

“…Indirectly, water is linked to the transmission of worms, such as schistosomiasis, ascariasis, taeniasis, oxyuriasis, and hookworms. These diseases are related to the consumption of non-potable water due to the lack of treatment, deficiencies in the treatment and supply systems, insufficient basic sanitation, and improper waste disposal (Bárta et al, 2021).…”

Springs enable the passage of groundwater to flow to the ground surface, forming and sustaining watercourses. Despite the importance of these ecosystems, their functionality and the availability of water in terms of quantity and quality in rural areas have been threatened. The objective of this study was to evaluate the water quality of springs under different care and preservation scenarios in rural areas and assess the need to combine water potability analysis with biological indicators and the effects of the interaction between aquatic and terrestrial environments on the characteristics of surroundings to generate a systemic and robust representation of the impact of human actions on these threatened environments. The study was developed considering the Ijuí River Basin, in the northwestern state of Rio Grande do Sul, Brazil. It involved the evaluation of springs in a native forest area protected by drainage and a preserved vegetation; in a reforested area with concrete protection and surrounding vegetation; and in a livestock area with no vegetation fragments in the surroundings and with an outcrop protected by concrete pipes. Physicochemical and microbiological analyses are essential for determining the potability of spring water. However, these are specific assessments that do not reflect historical environmental conditions. The use of bioindicators enables these analyses and, together with the determination of surroundings' characteristics, allows for evaluating the degree of preservation to ensure spring quality, providing perspectives that combine care and sustainable use.

Purpose: The objective was to evaluate the water quality based on physical and chemical parameters in different quadrants of an urban wetland and correlate variables that may show possible natural and anthropogenic polluting sources. Theoretical framework: Wetlands are essential ecosystems for the maintenance of ecological balance, biodiversity of organisms, and water reserves. Studies on water quality in urban wetlands are important for understanding their preservation level, elucidating the need for possible conservationist actions. Method/design/approach: The wetland area was divided into four quadrants; water samples were collected for analysis of physical and chemical. When possible, the results were compared with the limits established by the CONAMA Resolution 357/2005 (class 1), which deals with surface waters, and with the literature. Results and conclusion: The Quadrant 3, which presented riparian forest, invasive species, and high deposition of solid waste, showed a greater degree of environmental impact. Changes in several physical and chemical parameters indicate that the impairment of water quality in the evaluated wetland is mainly due to the anthropogenic action of the surrounding population. Research implications: The analysis of wetland water quality as an indicator of socio-environmental actions can be implemented and stimulate public power actions, ensuring its preservation. Originality/value: Studies in urban wetlands are rare. The irregular occupation on the banks denotes a socio-environmental issue. Wetlands are a valuable resource for environmental education practices in schools.
