E por fim, na discussão dos resultados, foram retomados aspectos teóricos e pesquisas sobre Educação Ambiental, Psicologia Ambiental e Cidadania Ambiental.

Dietary adjustment has been studied for the control and prevention of the Feline Lower Urinary Tract Disease. This work studied the influence of the amount of water and food digestibility on water intake and excretion (urinary and fecal). Ten adult female cats housed in metabolic cages were used. Four treatments were tested: low price dry food, low price dry food with 50% added water, super-premium dry food and canned food. Water intake with food and by drinking, fecal and urinary water excretion and food's digestibility coefficient were determined, in a Latin square experimental design with repetitions over time. The results were submitted to variance analysis; to Tukey's test to compare means and to Pearson's Correlation to test the association between variables (p<0.05). Moist food led to the highest water intake and the largest urine volume with the lowest density. The cats balanced the higher water intake with food by drinking less water. Adding 50% water to the food did not result in a higher total water intake and urine excretion. The lowest consumption of dry matter and highest food digestibility resulted in lower fecal water excretion. Dry foods with high and low digestibility had a urine:feces water excretion rate of 0.7:1 and 1.6:1, respectively. Among the nutrients, fat intake had a positive correlation with the urine volume. Foods with higher digestibility resulted in lower fecal water loss. Canned food (high water:dry matter ratio) led to the highest total water intake and urinary volume excretion, and lower urinary density. | A modificação dietética tem sido estudada e empregada no controle e prevenção da Doença do Trato Urinário Inferior dos Felinos. Este trabalho estudou a influência do teor de água e da digestibilidade das rações sobre a ingestão, excreção urinária e excreção fecal de água. Utilizaram-se 10 gatas adultas castradas, alojadas em gaiolas metabólicas.Testaram-se quatro tratamentos: ração enlatada; seca super-premium; seca econômica e seca econômica acrescida de 50% de água. Determinou-se a ingestão de água via alimento e bebedouro, a excreção de água via fezes e urina e o coeficiente de digestibilidade das rações. Foi empregado um quadrado latino com repetições no tempo. Os resultados foram avaliados por análise de variância seguido pelo teste de Tukey para a comparação de médias e a Correlação de Pearson para se verificar a associação entre variáveis (p<0,05). O consumo de ração enlatada proporcionou uma maior ingestão total de água e uma maior excreção de urina, que apresentou menor densidade. Os gatos compensaram a maior ingestão de água alimentar bebendo menos água. Quanto menor a ingestão de matéria seca e maior a digestibilidade do alimento, menor a excreção fecal de água, pois as rações secas de baixa e alta digestibilidade obtiveram, respectivamente, relação excreção de urina:excreção de água fecal de 0,7:1 e 1,6:1. A ingestão de gordura apresentou correlação positiva com o volume urinário. Rações de maior digestibilidade promovem menor perda fecal de água, mas somente a ração enlatada (alta relação água:matéria seca) proporcionou maiores ingestão total de água e volume urinário.

El presente trabajo de titulación se centró en llevar a cabo un examen exhaustivo de la calidad del agua en las vertientes Shushurí, localizadas en la provincia de Tungurahua, específicamente en la ciudad de Pelileo. Se realizaron actividades meticulosamente planificadas con el propósito de analizar los parámetros físico-químicos y determinar el caudal disponible, tanto en el sitio como en el laboratorio. El objetivo principal fue comparar los resultados obtenidos con los criterios de calidad establecidos en el Acuerdo Ministerial 097, Anexo 1, que regula las normativas pertinentes. Los parámetros analizados se seleccionaron debido a su alta prevalencia natural en el agua subterránea y su capacidad para indicar posibles contaminaciones externas y microbiológicas. Los datos recopilados proporcionaron información esencial para definir un uso específico del agua a través del método de índice de calidad del agua, evaluando su idoneidad para fines recreativos. Aunque se observó que el agua cumplía en su mayoría con los estándares establecidos, se identificaron ciertos parámetros, como el arsénico, que excedían los límites permitidos. Por lo tanto, se propuso un detallado plan de tratamiento del recurso hídrico con el fin de adaptarlo y mantenerlo en condiciones óptimas para su uso. Entre las medidas sugeridas se incluyó la aplicación de una titulación con ácido para reducir la concentración de alcalinidad y mantener un pH constante en el agua. Además, se recomendó la implementación de un aireador de escaleras, diseñado para aumentar la saturación de oxígeno en el recurso hídrico. Estas estrategias se consideraron soluciones efectivas para mejorar la calidad del agua y asegurar su aptitud para el uso recreativo, sin comprometer los estándares de calidad establecidos. | The present thesis focused on conducting a comprehensive examination of water quality in the Shushurí springs, located in the Tungurahua province, specifically in the city of Pelileo. Meticulously planned activities were carried out to analyze the physicochemical parameters and determine the available flow, both on-site and in the laboratory. The main objective was to compare the results obtained with the quality criteria established in Ministerial Agreement 097, Annex 1, which regulates the relevant regulations. The analyzed parameters were selected for their high natural prevalence in groundwater and their ability to indicate possible external and microbiological contaminations. The collected data provided essential information to define a specific use of water through the water quality index method, evaluating its suitability for recreational purposes. Although it was observed that the water mostly complied with the established standards, certain parameters, such as arsenic, were identified to exceed the permitted limits. Therefore, a detailed plan for treating the water resource was proposed to adapt it and maintain it in optimal conditions for use. Among the suggested measures was the application of acid titration to reduce alkalinity concentration and maintain a constant pH in the water. Additionally, the implementation of a staircase aerator was recommended to increase oxygen saturation in the water resource. These strategies were considered effective solutions to improve water quality and ensure its suitability for recreational use without compromising the established quality standards.

Se describe la evaluación realizada al sistema de tratamiento de agua potable en la comunidad de Tolontag, con el objetivo de identificar las áreas de mejora y garantizar la calidad del agua. Se realizó un plan de muestreo en cinco puntos específicos: tanque de captación, entrada y salida de la planta de tratamiento, y las dos viviendas más alejadas de la planta. Se analizaron parámetros in situ ( pH, conductividad, temperatura, oxígeno disuelto y turbiedad) y parámetros de laboratorio (arsénico, alcalinidad, DQO, DBO5, dureza total, hierro total, manganeso, fosfatos, nitratos, sólidos totales y disueltos, sulfatos, cloro libre residual y total, coliformes totales y fecales). Los análisis realizados al agua cruda de la comunidad indican que es de excelente calidad. Por tal motivo, el tratamiento actual se limita a la desinfección. Sin embargo, las pruebas revelaron que el proceso de desinfección no es efectivo, ya que las concentraciones de cloro total y libre residual son inferiores a los valres establecidos por la normativa. Para garantizar la calidad del agua para el consumo humano, se proponen mejoras al tratamiento actual, que se basa en un hipoclorador por goteo constante. Estas mejoras se enfocan en: Modificar la cantidad de desinfectante para preparar una solución madre adecuada, recalcular el caudal de goteo para asegurar una dosificación precisa y constante, ampliar el tiempo de contacto delmdesinfectante con el agua para una desinfección efectiva. Estas medidas permitirán garantizar que los habitantes de la comunidad tenganm acceso a agua potable segura y de calidad. | The evaluation carried out on the drinking water treatment system in the community of Tolontag is described, with the objective of identifying areas for improvement and guaranteeing water quality. A sampling plan was carried out at five specific points: collection tank, entrance and exit of the treatment plant and the two homes furthest from the plant. In situ (pH, conductivity, temperature, dissolved oxygen and turbidity) and laboratory parameters (arsenic, alkalinity, COD, BOD5, total hardness, total iron, manganese, phosphates, nitrates, total and dissolved solids, sulfates, chlorine) were analyzed. . . free of residual and total coliforms, total and fecal). The analyzes carried out on the community's raw water indicate that it is of excellent quality. For this reason, current treatment is limited to disinfection. However, the tests revealed that the disinfection process is not effective, since the concentrations of total and free residual chlorine are lower than the values ​​established by regulations. To guarantee the quality of water for human consumption, improvements are proposed to the current treatment, which is based on a constant drip hypochlorinator. These improvements focus on: Modifying the amount of disinfectant to prepare an adequate stock solution, recalculating the drip flow to ensure accurate and constant dosing, extending the contact time of the disinfectant with water for effective disinfection. These measures will ensure that community residents have access to safe, quality drinking water.

La presente investigación se ejecuto desde el 21 de octubre del 2021 hasta el 20 de junio del 2022 se llevó a cabo con el objetivo de determinar la calidad microbiológica del agua potable en el centro poblado de Marona, para el cual se seleccionó 20 puntos de monitoreo en las viviendas, de acuerdo a la ubicación de estas respecto a la red principal de distribución de agua. Se realizó los cálculos hidráulicos necesarios para el modelado de la red hidráulica del centro poblado Marona, para la posterior calibración del modelado de cloro residual, siendo esta un vertimiento de cloro de 1,80mg/L, el cual posteriormente fue verificado in situ que las concentraciones de cloro libre residual en campo sean considerablemente aproximadas a las concentraciones de cloro residual obtenidas en la simulación en el software WaterCAD. Para la determinación in situ se utilizó un medidor digital de cloro libre, realizándose dos muestras por vivienda, en el cual se obtuvo promedios entre 0,48mg/L a 1,14mg/L, los mismas que se encontraron aproximados a las concentraciones arrojadas en la simulación de cloro residual aplicada. Los resultados obtenidos fueron óptimos, entendiéndose así que, la calidad microbiológica del agua del centro poblado Marona se encuentra apta para el consumo su población. | Modeling and simulation of residual chlorine in drinking water to determine the microbiological quality of the water in the Marona village The Peruvian standard requires a minimum residual chlorine concentration of 0.50 mg/L in drinking water. The present investigation was carried out from October 21, 2021 to June 20, 2022 with the objective of determining the microbiological quality of drinking water in the town of Marona, for which 20 monitoring points were selected in households, according to their location with respect to the main water distribution network. The necessary hydraulic calculations were made for the modeling of the hydraulic network of the Marona village, for the subsequent calibration of the residual chlorine modeling. A chlorine discharge of 1.80 mg/L was obtained, which was later verified in situ to ensure that the free residual chlorine concentrations in the field are considerably close to the residual chlorine concentrations obtained in the simulation in the WaterCAD software. A digital free chlorine meter was used for the in situ determination, and two samples were taken per household, obtaining averages between 0.48 mg/L and 1.14 mg/L, which were found to be close to the concentrations obtained in the residual chlorine simulation applied. The obtained results were optimal, meaning that the microbiological quality of the water in the Marona village is suitable for human consumption.

La gran mayoría de las personas de la ciudad de Bogotá durante la actividad de aseo personal o ducha dejan evacuar el agua fría hasta tanto ésta se caliente. De esta manera hay un volumen de agua que se desperdicia, al no darle ningún uso. Dicho desperdicio tiene un costo para el usuario y además una pérdida de disponibilidad de agua potable, los cuales pueden ser bastante significativos. Este estudio evalúa el volumen de agua que se pierde desde el momento en que se abre la llave de agua caliente en la ducha hasta el momento en que el agua alcanza la temperatura deseada por el usuario para tomar un baño. Para esta evaluación se realizó un muestreo de 100 viviendas (20 por cada estrato), con excepción del estrato 1 para el cual no se encontró vivienda que tuviera un sistema de agua caliente para la ducha. Se encontró que el Estrato 2 pierde un volumen promedio de 2,87 L por habitante por ducha; el Estrato 3 un promedio de 2,3 L; el Estrato 4 un promedio de 2,51 L; el Estrato 5 un promedio de 3,1 L y el Estrato 6 un promedio de 4,3 L. Para la población total suscrita al sistema de acueducto que toma una ducha, la pérdida en el mes es de 542.000 m3, con un costo aproximado de 2.400 millones de pesos mensuales. | In the city of Bogota, most of the people during the activity of personal hygiene or shower leave to drain the cold water until it warms up. In this way there is a volume of water that is wasted, by not using it at all. This water waste has a cost for the user and a loss of availability of drinking water, which can be quite significant This study evaluates the volume of water that is lost from the moment the hot water tap is opened in the shower until the moment when the water reaches the desired temperature for the user to take a bath. For this evaluation, a sampling of 100 homes was carried out (20 for each social stratum), with the exception of stratum 1 for which no home was found that had a hot water system for the shower. The results shows that Stratum 2 loses an average volume of 2.87 L per habitant per shower; Stratum 3 an average of 2.3 L; Stratum 4 an average of 2.51 L; Stratum 5 an average of 3.1 L and Stratum 6 an average of 4.3 L. For the total population subscribed to the aqueduct system that takes a shower, the loss in the environmental impact reaches 542,000 m3 per month, with an approximate cost of 2,400 million pesos per month. | Maestría | Magíster en Ingeniería Civil con Énfasis en Recursos Hidráulicos y Medio Ambiente
