Given the extensive use of pesticides in modern times, residues are frequently detected in water samples. Therefore, this study developed and validated a method utilizing solid-phase extraction (SPE) with a polymeric sorbent for sample preparation in combination with ultra-high performance liquid chromatography coupled to tandem mass spectrometry (UHPLC-MS/MS). The aim was to determine a variety of current-use pesticides (CUPs) in different types of water. The preconcentration step, employing the polymeric sorbent Oasis HLB (60 mg), combined with the high selectivity and sensitivity of the UHPLC-MS/MS analysis, enabled the multiclass determination of pesticide residues in water samples at very low concentrations. The proposed method underwent validation, demonstrating satisfactory linearity, precision, and accuracy. The accuracy results, determined through recovery assays at varying spike levels (0.04-0.4 μg L-1), ranged from 71 to 117%, with precision expressed as relative standard deviations consistently below 19%. The practical limits of detection and quantification for most compounds were 0.01 and 0.04 μg L-1, respectively. This method was effectively employed to analyze drinking water, artesian well water, dam water, and river water, leading to the detection of various pesticides at concentrations of up to 2.24 μg L-1.

The objective of the article is to analyze the impact of the National Sanitation Plan (Planasa) in the State of Mato Grosso (MT). The initial chronological milestone highlights the year Planasa was implemented, and the final milestone highlights the year in which the public financing program for sanitation, implemented by the Civil-Military Regime, ended. The analysis will focus on the following aspects: (1) state government initiatives aimed at promoting basic sanitation; (2) the performance of Companhia Saneamento do Estado de Mato Grosso (Sanemat); and (3) the numbers that record the gradual expansion in the water supply and sewage collection networks. Within this scope, the article was subdivided into four sections. The first corresponds to the Introduction and presents an overview of sanitation in Mato Grosso, before the creation of Planasa. The second highlights the period between the implementation of the Plan and the creation of the State of Mato Grosso do Sul, which occurred in 1977. [ABSTRACT FROM AUTHOR]

Studies involving the hydrological theme are essential to understand the dynamics surrounding the cyclic processes of water. Ensuring water supply is a challenge for human society. In this context, springs are central ecosystems in terms of distribution and supply of water. This research aimed to study the springs, placing the theme in the legal and practical context of conservation of these environments. For the development of the study, the upper course of the Pacoti River was framed, which is inserted in the Massif of Baturité, in the state of Ceará. Field work was carried out for the spatial survey of the springs, as well as the subsequent environmental assessment after determining the degree of protection. To achieve these results, the Environmental Impact Index on Springs - IIAN was applied, with which macroscopic parameters are evaluated. The methodology was applied in 19 springs, using the criterion of preservation of the natural aspects necessary for the development of the analysis. It was possible to make observations about the use of springs on private properties, especially the practice of inserting pipes in the exfiltration site, completely disrupting the flow of natural drainage downstream. These uses were discussed observing the legal provision inserted in the Brazilian Forest Code. The relevance of studies that try to raise spatial and environmental information on springs was verified, since the degradation of these areas can possibly impact the entire surface hydrographic network.

ABSTRACT Objectives: to identify immersion use in hot water to relieve pain in newborns. Methods: an integrative literature review, carried out in the PubMed, VHL, EMBASE, Scopus, CINAHL, Cochrane and SciELO databases, with investigations in English, Spanish, French or Portuguese, published between 2002 and 2022. The Health Sciences Descriptors (DeCS) and Medical Subject Headings (MeSH) were used to answer the following question: what are the uses of hot water immersion in relieving pain in newborns? Results: nine studies were included, mainly Brazilian, experimental, with a predominance of strong and moderate levels of evidence. Hydrotherapy and bath use (immersion and bandaging) was observed, promising interventions in reducing pain scores, assessed using scales, physiological and endocrine parameters. Conclusions: hot water proved to be a promising non-pharmacological intervention in relieving pain in infants in different contexts.

In the face of the global need to reduce resource consumption, green building labels are presented as a possibility for gaining efficiency in the construction industry. This study aimed to measure the energy and water consumption of a vertical residential green multifamily building located in Belém, in the Brazilian Amazon. The energy and water consumption data of two similar buildings were compared, where only one of them implemented mandatory green practices and technologies for the Leadership in Energy and Environmental Design (LEED) Environmental and Core and Shell certification. As a result, it was found that water consumption exceeded the estimated values by 30.64%, while electricity consumption was 24.6% below the estimated values in the design phase and 1.73% lower than the non-green building. These findings differ from some literature and demonstrate that user behavior can significantly impact the energy and water efficiency of green building technologies. Particularly regarding water consumption in the Amazon region, where high water consumption may be related to its abundance and the user's disregard for this resource.

Christian Petzold’s drama Undine, a Franco-German co-production released in 2020, transfers the romantic myth of the scorned nymph into present Berlin. This is the first part of a trilogy planned by Petzold on figures of German Romanticism, which will intend to bring the so-called elemental spirits closer to our reality. The result is a poetic film fairy tale, in which the main characters move between two worlds: not only underwater and on land, but also between reality and fantasy, between the present and the past. Petzold shows that the myth of Undine is ahistorical and doomed to be repeated endlessly. His adaptation, however, deviates decisively from the literary models and thus not only reveals a determined reshaping of the myth, but also blurs through its peculiar aesthetics, grounded in the foundations of the Berlin School, the fine line between reality and fantasy.

Evaluation studies contribute to the identification of parameters that can affect the accuracy and precision of analytical methods. This study describes the analysis of δ18O and δ2H in water samples by the equilibrium method at the Isotope Geology Laboratory (LGI), Center for studies in Petrology and Geochemistry (CPGq) of the Federal University of Rio Grande do Sul (UFRGS). For that, six batches of analyzes were carried out under different ambient temperature conditions. For the reproducibility tests, four aliquots of the control sample were analyzed at the Polar Climate Center (CPC). Results showed that ambient temperature did not significantly affect the accuracy of the oxygen analysis. However, the mean result at 20 °C showed greater accuracy and acceptable precision. Hydrogen analyzes at a room temperature of 18 °C showed an external standard deviation and an internal precision exceeding the recommended, while at 20 and 22 °C the results were statistically acceptable, being the first more accurate. From that, it is possible to conclude that the determination of δ18O and δ2H in water at the LGI, employing the equilibrium method at an ambient temperature of 20 °C, showed satisfactory repeatability and reproducibility.

Objective: To assess the fluoride concentration of bottled waters from municipalities in northeastern Brazil. Material and Methods: Bottled mineral waters were purchased in two periods at different commercial places of four large municipalities (João Pessoa, Campina Grande, Patos, and Cajazeiras) in the Paraíba state. The municipalities selected to present the following annual average temperature: João Pessoa 26.5 °C, Campina Grande 23.3 °C, Patos and Cajazeiras 27.5 °C. Fluoride concentration was determined using a combined ion-specific electrode. Readings (in mV) were conducted in triplicates for each standard solution and converted into fluoride concentration (mg F/L) using the Excel® software. Results: A total of 72 samples from six brands of bottled water were analyzed. The fluoride concentrations of all samples were low (0.11-0.21mg/L) but higher than those reported on the label and varied among different batches of the same brand. Conclusion: The fluoride levels in bottled water vary among brands, and these actual values are not stated in the labels.

In Brazil, the National Health Surveillance Agency (ANVISA) created the Program for Analysis of Pesticide Residues in Food (PARA) in 2001 with the purpose of evaluating pesticide residue levels reaching the consumer’s table. Currently, all Brazilian states participate in this program, except for Paraná, which established its own program in 2011 and ceased to participate in ANVISA’s analyses in 2016. In this context, this article aimed to analyze the results of pesticide residue monitoring in food in the state of Paraná and discuss the advances and limitations within the state program. The methodology relied on exploratory documentary research, analyzing reports from the Program for Analysis of Pesticide Residues in Food coordinated by ANVISA and the State Program for Analysis of Pesticide Residues in Food (PARA/PR), made available on the website of the Paraná State Health Department (SESA/PR). Additionally, bulletins and reports from the Surveillance and Health Care Plan for Populations Exposed to Pesticides in the State of Paraná (PEVASPEA) were also examined. It was identified that, on average, 60% of food samples analyzed in Paraná between 2001-2019 contained some level of pesticide contamination. The most frequently detected irregularities were found in samples of bell peppers, strawberries, cucumbers, and grapes. There are indications of multiple exposures, as some foods, such as strawberries, presented an average detection of up to eight different active ingredients per sample. The mos detected pesticides belong to the dithiocarbamate group, as well as carbendazim, imidacloprid, and tebuconazole. Thus, this study intends to raise awareness about the essential need to consider and demand less harmful methods for the environment and human health in food production, while promoting strategies for proper nutrition

This article proposes a comparative literary analysis through two texts: Isabel Allende’s Paula, a memoir inspired by her daughter’s death, and Love in the Time of Cholera by Gabriel García Marquéz, a fictional novel that incorporates magical realism, to recognize the generative possibilities and power of water in illness narratives. The texts unfold in Chil, San Francisco, and the Caribbean coast of Colombia, situating the Latinx texts as coastal, place-based stories. Thus, I am interested in the implicit and explicit ways water functions as a sustaining lifeforce and a symbolic border between life and death. Given water’s duality, I am also interested in the generative relationship and tension between bodies of water and the human body, which is 75% water. I will explore how each text uses metaphors of water to explain, or conceptualize, loss and love related to illness. Each text deals with transition in illness – at times painful, transformative, heartbreaking, and revelatory – and I argue that in so doing they embody the fluidity and ambiguity of water.

Fossil fuels are used throughout the world as the main sources of energy, they are present in nature thanks to the accumulation of biomass over millions of years. Although many countries depend largely on exports of oil and its derivatives to maintain their economy, fossil fuels have caused pollution to the environment due to their extraction from the subsoil, causing harmful effects on the human being and the environment as a result of the operations related to their exploitation. This bibliographic review article exposes a series of theoretical and conceptual considerations about the effects of the exploration, exploitation, and production of fossil fuels such as oil and gas, focusing on the negative effects that these activities cause on natural resources in Colombia. and Latin America, in addition to considering different measures to prevent and mitigate the impacts caused.

Water is a factor present in human life at all times of its existence. The correct management of it, whether for the supply and enjoyment of social needs, or the control of rainwater and the like are challenges present in virtually all major population centers in the world. In this way, the present research aimed to study the Canal da Avenida Doutor Moraes, in Belém/PA, inserted in the Estrada Nova Hydrographic Basin, to evaluate its performance conditions, the authorities' care for this system, the users' responsibility, and the physical state and conservation of its micro and macro drainage components. The canal cuts through several avenues in the neighborhood of Batista Campos, being very close to the neighborhoods of Cremação and Jurunas. The components of the Canal are well preserved due to a certain awareness of local residents and a well-defined agenda of the competent authorities that carry out periodic cleaning in the place, in addition to plans for dredging the channel, which in a certain section suffers from silting. The problems only revolve around occasional situations of disrespect on the part of users who irresponsibly dump residential solid waste, in addition to making clandestine connections without due care for the channel's reinforced concrete structure. Finally, it was observed that the systems can only be preserved with the union and joint work of the public power with the population, where each one performs its role before the responsibilities for the rights and duties can maintain the necessary balance for the well-being of the population as a whole.

The aim of the research was to compare the yields of house fly larvae using different proportions of wheat bran and swine feces as larval development medium, in a randomized block experimental design with five replications: A-100 % wheat bran; B- 50% wheat bran and 50% swine feces; C- 100% swine feces. Measurements of the temperature of the substrates, as well as the temperature and relative humidity of the place where the flies were developing were made every 24 hours. The larval yield per m2 and kg of substrate, (including the water used to moisten the larval media) were also registered. The wheat bran substrate presented the highest temperature values (36.78 oC), with values above the ambient temperature. The relative humidity varied between 44 and 68%. The amount of water used per square meter was 28.75; 27.72 and 28.87 L for A, B and C treatments, respectively. The highest yield for all substrates was obtained during the first harvest after six days with the highest values for treatment B with 2869.11 g m²-1 and 181.16 g kg-1, respectively. The transformation of the crude protein of the substrates by the fly larvae was between 28.0 and 41.0%, with the highest value for treatment B with 2869,11 g m² -1 and 181,16 g kg2-1 . No presence of pathogenic agents was observed in the harvested larvae.

ABSTRACT Diabetes insipidus is a rare disorder characterized by the inability to concentrate urine, which results in hypotonic urine and increased urinary volume. It may occur because of antidiuretic hormone deficiency or resistance to its action in the renal tubules. When there is a deficiency in the synthesis of antidiuretic hormones, diabetes insipidus is called central; when there is resistance to its action in the renal tubules, it is said to be nephrogenic. We report a case of idiopathic partial central diabetes insipidus and highlight the management and treatment of the disease.

This article aims to present data and indicators that improve the understanding of the central difficulties and challenges at the municipal and regional level in water management and sanitation promotion in the Brazilian Amazon, in compliance with national legislation and the Sustainable Development Goals (SDGs). Official databases and semi-structured interviews are used to gather the perception of scholars, managers, technicians and other key local actors. Central elements that contribute to the large déficit of water and sewage services in two municipalities in the state of Amazonas (Manaus and Manacapuru) are highlighted, including social, economic and municipal management indicators. The results show, in addition to the déficit, social vulnerabilities, structural, economic and management gaps as obstacles to the universalization of sanitation. To overcome this reality, it is necessary to strengthen governance based on local knowledge, opportunities and capacities.

Brazil is recognized internationally as the “Land of Water", in particular for its huge dams distributed throughout the country. More generally, Brazil is famous for its plentiful water resources, consisting of rivers, streams, lakes and springs, and also the accumulation of groundwater, described in studies of several cities in the five official Brazilian regions. In the Northeast region, for example, the impact caused by the construction of the Sobradinho Dam in the state of Bahia in 1973 on a stretch of the São Francisco River, which entered activity in 1979, made it possible to improve the lives of the residents of cities, including in nearby states and promoting stability of the nation's energy supply. In the North region, we can highlight surface water sources and aquifers, respectively, such as the Tapajós, Negro, Solimões rivers, among others, and groundwater reserves such as Alter do Chão located in the state of Pará. In the Southeast region, the state of Rio de Janeiro has plentiful surface water availability from the Paraíba do Sul River, which supports the consumption of more than 50 municipalities. In addition to Rio de Janeiro, the other states of the region (Minas Gerais, São Paulo and Espírito Santo) contain water sources that have ensured the survival of their high demographic density over the years, indicating the importance of preservation and new methods of use of wastewater reuse or restoration to the environment. In the South region, attention has been drawn to the challenge of managing the uses of water resources for better exploitation of the excess water stemming from periods of flood, to reduce the dependence on the use of aquifers in Serra Geral and Guarani. In turn, the Midwest region is supplied by the Tocantins-Araguaia, Paraná, Amazon, Paraguay and São Francisco rivers, but is subject to the problem of deforestation of riverside areas and lack of proper sanitation. In the final analysis, the water resources in Brazil are an intangible heritage requiring measures for wise distribution to the population while preserving the environment, for the benefit of the country itself and the world.

Background: The fluoridation of water supply has been pointed out in national and international studies as the most efficient and equal way of accessing fluorides in the prevention of dental caries. Objective: To report the results of heterocontrol in public water supply in the municipality of Colombo/PR, from December 2013 to November 2014. Method: The samples were monthly collected in 15 Basic Health Units, on random days of the week, from 12/2013 to 11/2014. The samples were analyzed by the electrometric method at the Faculty of Dentistry of Fluminense Federal University. Results: 180 samples were analyzed, ranging from <0.001 to 1.480 mg/L (mean 0.715 ± 0.232 mg/L). According to the criteria established by the Collaborating Center of the Ministry of Health in Oral Health Surveillance, 51.11% of the samples had adequate fluoride levels, 13.34% above ideal fluoride levels, and 35.56% below ideal levels. Conclusion: Heterocontrol could represent one of the main strategies of oral health surveillance, and, therefore, it should be implemented and carried out in all regions that use fluoridated water, in order to guarantee the maintenance of optimal fluoride levels.

Food and waterborne diseases (DTHAs) and healthcare-associated infections (HAIs) represent an important public health problem. Among the possible etiological agents of DTHAs and HAIs, are mainly bacteria. In this context, we can highlight some bacteria such as Escherichia coli and Staphylococcus aureus, which are also involved in the contamination of food and healthcare environments. The objective of this study was to evaluate the microbicidal potential of ozonized water against Escherichia coli and Staphylococcus aureus at different concentrations and exposure times. For this, bacterial suspensions of E. coli and S. aureus were exposed to ozone under different times (1, 2 and 5 minutes) and concentrations (50, 100 and 150 ppm). After each time of ozone application, aliquots of the inoculum were collected and seeded on specific agar and incubated at 37ºC for 24-48 hours. After the incubation time, the colony forming units (CFU) were quantified and the results displayed as mean ± standard deviation and compared using the analysis of variance test (ANOVA) with Tukey as post-test. Ozone when released in a liquid medium proved to be efficient in quantity reduction both species of bacteria tested, above all, it seems to exert greater lethality on E. coli when compared to S. aureus. The action of the gas proved to be very effective, requiring low concentrations, in addition it proved to be quite fast since even in short exposure times it was able to kill bacteria significantly, even when used at low concentrations.

Paraná is a geographically privileged state in terms of water resources. Nevertheless, there is a growing concern about the supply to population, especially in large urban centers. The growth of population and economie, as well as the demands for natural resources, are distinct between cities throughout the state, causing imbalances in the supply of water and sanitation. This article seeks to raise projections of water demands, already made available by competent bodies in the country, and identify needs in sanitation, in order to list possible bottlenecks to long-term economic development. Therefore, a documentary research was carried out, as well as a brief literature review on the subject, highlighting the reading in which the growth of water demand is considered under four scopes: human, economic, ecosystem and resilience. Access to water is an essential condition for maintaining life and productive activities. The potential pollution of rivers in large cities, especially in the Metropolitan Region of Curitiba, can be circumvented with efficient measures and strategic studies, as highlighted by the State Water Resources Plan of Paraná. Regarding sanitation, remains a necessary attention to the sewage collection network, for which there is a significant margin for closing indices near to universalization levels. The task is accentuated in areas of the interior of the state. [ABSTRACT FROM AUTHOR]

The aim was to design a continuous flow reactor for the experimental removal of lead by electrocoagulation in the waters of the Coata River in Puno, Peru. The reactor design consisted of two flow-through cells that were connected by a pipe channel. The dimensions of the cells were as follows: 17 x 20 x 30 cm. The electrodes measured 23 x 11 cm. and with an additional 1 cm2 . Likewise, the voltage source was 50 Vdc with a current density of 0.8 A. The exit angle for the fluid was 45° where there was a flow of 0.008 L/s with 18.36 minutes of retention time in the first cell. and 34.68 min in the second, respectively. The initial concentration of lead in the untreated water sample was 0.081 mg/L-1. For the first cell, the concentration found was 0.038 mg/L-1, while 0.011 mg/L-1 corresponded to the second cell. The results indicate a removal percentage of 53% and 86% for each cell. It is concluded that the design of the continuous flow rector satisfactorily removed lead concentrations in the waters of the Coata River in Puno, Peru under experimental conditions.

Currently, in critical times of confinement, hydroponics is a viable alternative that allows the production of plant biomass derived from the initial development of plants in the stages of germination and early growth of seedlings from feasible seeds, it is the sowing of soilless cultivation, this method facilitates the productive, sustainable, and ecological development of plants. Hydroponic crops are developed in a medium or culture system fed by a nutrient solution that offers the precise food for the entire period of growth of the forages, free of pesticides and fungicides with this we get healthy food for the feeding of domestic animals. In addition, it allows the use of simple or complex structures to produce fodder, taking advantage of spaces or areas such as terraces, infertile soils, rugged terrain, technical or traditional greenhouses. Based on this idea, techniques were deployed that are supported by using substrates, or methods with contributions of nutrient solutions, always considering the needs of the plant such as temperature, humidity, water, and nutrients. Based on practice, the benefits per unit of planted area are high due to greater consistency, productivity, safety, and efficiency in the use of water, light, and nutrients, and it is also economically viable that deserves to be considered by small and medium- sized companies. rural producers of domestic animals.

The use of water as a natural resource is essential for the existence of life on the planet, and a recurring theme in various spaces of discussion and investigation, due to the concern of all social spheres. Water resources and related ecosystems are related to water resources, sustainable use of water changes and climate change. A worldwide source with a view to large use, due to its global form, it is guaranteed to verify the patterns of use by the large capacity, not considering that they can be presented by the large amount of water predicted9. 2011, in addition to the ability to transmit pathogens presents in the feces. There are several methods for the analysis of bacteria of the coliform group and Escherichia coli, among them the organisms are of the Most Probable Number, in which a technical estimate is made of how many are present in the original sample. This method is done through a series of serial dilutions, using the inverted Durhan tube to analyze the presence of microorganisms and the bright green broth 2% lactose bile to confirm the presence of total and thermotolerant coliforms. After the sample sampling period, the calculation of how many microorganisms that were analyzed are present in the sample is made. The present reviews data on water use, consumption and distribution, use of the most likely number method and its application to the analysis of water from artesian wells. With an increase in the need for education and an increase in the need to increase the number of equipment, in addition to the need to increase the amount of information, and not to increase the need to increase the number of equipment needed, in addition to the need to increase the amount of information and not to increase the need to increase the number of equipment needed.

This article aims to investigate the profile of water consumption during the pandemic period caused by the new coronavirus (SARS-CoV-2), analyzing the behavioral specificities of the population in this new everyday reality, limited to the perception of water consumers in the region. metropolitan region of Belo Horizonte. A field research proposal was adopted with different users from the municipalities of Belo Horizonte, Betim, Contagem, Ibirité and Ribeirão das Neves, in the state of Minas Gerais, evaluating the behavior of water consumption during the Covid-19 pandemic in the months of April to September, from 2019 and 2020. It was noticed that there was an increase in water consumption for 65% of respondents in view of the routine changes caused by Covid-19. In all the homes studied, it was identified that water consumption occurred through washing clothes, bathing and washing cars, representing, therefore, an opportunity to adopt practices aimed at saving water.

En el artículo que presentamos ofrecemos una aproximación a la poesía infantil, centrándonos en la presencia que el “agua”, como símbolo y elemento estético, adquiere en los textos contemporáneos. Desde el prisma de la ecocrítica literaria, nos acercamos a algunos de los referentes más importantes en la actualidad para hacer una descripción general. A la vez, ponemos de manifiesto el papel tan importante que este elemento de la naturaleza adquiere en el germen de la escritura poética y, al mismo tiempo, en su recepción por los lectores infantiles y juveniles. Partimos de la necesidad de recuperar la lectura de la poesía en las aulas, de dar de nuevo el protagonismo a este género que va quedando marcado por un halo de elitismo que lo aleja de los lectores, para pasar a describir cómo los elementos naturales y, concretamente, el agua, se manifiestan en muchos de los autores y títulos actuales. Con ello, mediante una metodología de análisis descriptivo, tratamos de ofrecer un corpus que sirva de referencia a los mediadores para abordar la lectura poética en el aula desde una conciencia ecológica, que ayude a conectar a los escolares con un imaginario cargado de simbolismo. In the article we present, we offer an approach to children's poetry, focusing on the presence that “water”, as a symbol and aesthetic element, acquires in contemporary texts. From the prism of literary ecocritics, we approach some of the most important references today to make a general description. At the same time, we highlight the important role that this element of nature acquires in the germ of poetic writing and, at the same time, in its reception by children and young readers. We start from the need to recover the reading of poetry in the classroom, to give prominence again to this genre that is being marked by a halo of elitism that takes it away from readers, to go on to describe how natural elements and, specifically, water is manifested in many of the current authors and titles. With this, through a descriptive analysis methodology, we try to offer a corpus that serves as a reference to mediators to address poetic reading in the classroom from an ecological conscience, which helps connect schoolchildren with an imaginary loaded with symbolism.

This article starts from the problematic about the approach to water in the scope of Environmental Education (EA), resulting from reflections from an extracurricular internship carried out through the institutional agreement between the Federal University of Santa Maria (UFSM) and the University of Minho (UMinho), in Portugal. The objective of this article is to carry out an analysis of the techniques used in EA and water activities promoted by the Landscape Laboratory (LdP). The methodology was based on a work plan based on three actions: survey and inventory of environmental education programs and activities; proposed pedagogical practices around water; transnational action. The analysis of the activities was carried out from a data survey and organization in spreadsheets. As a result, we evaluated 18 AE actions promoted and/or articulated by LdP, highlighting LdP as a reference in the scope of EA and water. [ABSTRACT FROM AUTHOR]

Water has a sensitive role in shaping both urban landscape and social life in Belem. In contrast, Belem's urban history is dominated by discourses and public policies responsible for creating an antinomy between city and water. This denial of the relationship with water unfolds, in part, interventions over city lowlands which were historically habitated by poor migrants from the countryside or other states. This article focuses on everyday practices related to water from inhabitants of the areas known as baixadas after the conclusion of a massive urban development program in the Una River Basin. Data was built through ethnographic research specially walks along the river basin channel, participant observation, interviews, and informal conversations with residents from areas affected by the Una River Basin Project. The relationship of these residents with hydric landscapes is altered by urbanization, but last in time through memory, since water articulates with their collective and individual trajectories. Thus, Belem's river margins must be considered not only as objects of intervention, but also as spaces of sociability in which everyday practices informed by memory reshape the public policies on water.
