No Semiárido Alagoano os estudos sobre os parâmetros de qualidade de água ainda são pouco documentados e, em alguns casos, escassos, quando comparado à região costeira do estado, desta forma, análises esporádicas nesses corpos d’água tornam-se imprescindíveis. Objetivou-se no presente artigo analisar os parâmetros físico-químicos de qualidade de água em sete nascentes localizadas nas áreas rural e urbana do município de Olho D’Água do Casado, Semiárido Alagoano. Foram coletados dados in situ de pH, temperatura, sólidos totais e condutividade elétrica com auxílio de um sensor óptico. À exceção do parâmetro temperatura, constatou-se que a maioria das nascentes analisadas, nas duas áreas, apresentaram padrões de qualidade de água que extrapolam as diretrizes da Resolução CONAMA/2005. Comparativamente, as nascentes da área urbana apresentaram maior dinâmica e maiores níveis discrepantes nos parâmetros analisados. Faz-se necessário a elaboração de um quadro com medidas mitigadoras que abranjam tanto a esfera socioeconômica quanto a ambiental, visando dar a estes mananciais uma melhor proficiência para a população residente em seu entorno, tanto para fins de abastecimento quanto para criação e agricultura, e concomitantemente buscando o equilíbrio entre sua utilização e a reparação e preservação da dinâmica natural. É pertinente afirmar que o banco de dados obtido tem elevada relevância social, científica e ambiental no que concerne à qualidade de água no Semiárido Alagoano, servindo de base para o uso e manutenção consciente das nascentes estudadas e como subsídios para futuros trabalhos. Water Quality Parameters in Springs in the Municipality of Olho D'Água do Casado, Alagoas Semiarid A B S T R A C TIn the Alagoas Semiarid, studies about the parameters of water quality are still poorly documented and, in some cases, scarce when compared to the coastal region of the state, so sporadic analyzes in these bodies of water become essential. The aim of this study was to analyze the physical and chemical parameters of water quality in seven nascent located in the rural and urban areas of the municipality of Olho D'Água do Casado, Alagoas Semiarid. In situ data of pH, temperature, total solids and electrical conductivity were collected with the aid of an optical sensor. With the exception of the temperature parameter, it was verified that most of the nascents analyzed in both areas presented water quality standards that exceed the CONAMA/2005 Resolution guidelines. Comparatively, the nascents of the urban area presented greater dynamics and higher levels of discrepancy in the analyzed parameters. It is necessary to create a cadre with mitigating measures that cover both the socioeconomic and environmental spheres, aiming to give these sources a better proficiency for the population residing in their surroundings, both for sourcing purposes and for breeding and agriculture, and concomitantly seeking the balance between its use and the repair and preservation of the natural dynamics. It is pertinent to affirm that the database obtained has high social, scientific and environmental relevance regarding water quality in the Alagoas Semiarid, serving as a basis for the conscious use and maintenance of the nascents studied and as subsidies for future works.Keywords: Spring, Semiarid, chemical-physical analysis.

Different Characteristics

<p>A detailed study of the mechanisms generated through the turbidity plume and its variability at the Guadalquivir estuary has been carried out with remote sensing and in situ data. Several sensors with different characteristics have been required (spatial, temporal and spectral resolution), thereby providing information for a multi-sensor analysis. The main objective was to determine the water quality parameters (suspended solids and chlorophyll) and implement the methodology to define the empirical and semi-analytical algorithms from satellite data (MODIS, METIS, Deimos-1). The processes occurred in the estuary and adjacent region have been examined identifying those involved in the different variability scales. The forcings associated with rainfall and discharge from Alcalá del Río dam in addition to the climatic NAO index control seasonal and inter-annual fluctuations, while tide effects (semi-daily and fortnightly cycles) modulate the plume at the mouth throughout the year with significant variability. Special emphasis is focused on diagnosing the role of these mechanisms on the continental shelf ecosystems, constituting a powerful tool for the water quality management and coastal resources.</p>

The study was conducted in a peri-urban village named, Panchpy under Gafargaon upazila of Mymensingh district with stinging catfish (Heteropneustes fossilis ) and carps ponds to produce aquaponics vegetable kolmi (water spinach, Ipomoea aquatica ) towards using waste substances of intensive stinging catfish ponds. Aquaponic plant (water spinach, Ipomoea aquatica ) was grown in floating trays in the selected ponds. The water quality parameters including, temperature, pH, dissolved oxygen, nitrite and ammonia were measured during study period.The level of ammonia was higher in catfish pond compared to carps pond water. Inversely, the dissolved oxygen content of catfish pond water was lower than that of carps pond. In the stinging catfish pond, the mean value (± SE) of plant length, weight, number of branches and leaves were recorded at 27.67 ± 1.76, 62.67 ± 2.03, 13.00 ± 1.15 and 55.33 ± 3.18, respectively. The corresponding values 19.33 ± 1.45, 46.67 ± 1.86, 9.33 ± 1.45 and 43.00 ± 2.88, respectively in carps pond, were significantly lower than that of catfish pond. Overall the percent weight gain of kolmi was higher in catfish pond. A positive correlation was found between the length and weight of kolmi produced in both catfish and carp ponds, however R2 value of that relationship was higher for catfish pond due to higher level of available waste nutrients in water. This indicates that the potential of aquaponics research and development in intensively feed catfish aquaculture ponds at the farmer level that can feed the growing population in both rural and urban areas of Bangladesh.Res.

<p>Trophic structure deterioration in continental water bodies (lakes and damps) has been a growing problem during the last years. Numerous factors, either natural or man-made contribute in value increments of various water quality indexes ranging toward eutrophication. Our study had objective to use remote sensing as complementary tool to study the spatial distribution and dynamics of Lake Vichuquén water quality parameters in two seasons of 2016 through the use of two satellite images of the Landsat 8 OLI sensor, with in situ and laboratory data. The Chl-a and Z<sub>SD</sub> parameters were estimated from multiple linear regression models. The results indicate that the trophic state of Lake Vichuquén corresponds to a eutrophic level in summer and mesotrophic in autumn. The laboratory analyzes establish for the summer and autumn season that the Chl-a data oscillate between 14.1 and 5.5 μg/l and for the Z<sub>SD</sub> between 3.7 and 2.5 m respectively. The increase in the levels of eutrophication of Lake Vichuquén is influenced in the first place by the seasonality and secondly by the different land uses that accelerate this type of processes; such as the plantations of radiata pine and eucalyptus, the agricultural activities and the urban areas surrounding the lake. The mean square error for each variable and each season varied in Chl-a in summer and another year 0.74 and 0.01 µg/l and Z<sub>SD</sub> 0.16 m respectively.</p>

The São Jorge stream micro basin, located in the municipality of Tarabai-SP, is divided into rural and urban areas, with the presence of livestock activities, residential and commercial buildings, as well as a flour industry. Human interference has been modifying water resources, making it necessary to monitor them and identify negative changes. Thus, in order to analyze the water quality of this micro-basin, pH, chemical oxygen demand, turbidity, electrical conductivity and nitrogen were analyzed to check for possible disagreements with the legislation. The results were compared to CONAMA 357/2000, which allowed to find discrepancies in the sample with greater proximity to the industry (4). The qualitative analysis of the stream made it possible to understand how much interference in the micro basininterferes negatively in thequality of its water; they are often not visible or easy to identify, but they are present altering the characteristics of the water.

Laundry services are rapidly becoming ubiquitous in rural and urban areas, generating high domestic waste volumes. Their growth has raised concerns about the quality of natural waters, particularly the rivers into which most laundry businesses discharge their wastewater. The research set out to study laundry wastewater characteristics and their relationship with the river water quality as water pollution indicators in Code Watershed (Indonesia). It lies in three administrative units where many human activities take place in the watershed’s upper to the lower reaches. BOD and COD of 25 sampled laundry businesses were analyzed descriptively and compared to the laundry wastewater standards stipulated in Regulation No. 7 of 2016 and the class II water quality standards issued in Governor Regulation No. 20 of 2008. The results showed that the BOD of four laundry businesses and the COD of 18 laundry businesses exceeded the predetermined standards. Overall, rivers in Code Watershed meet the class II river water criteria for BOD at three of the seven sampling points and COD at all points.
