Abstract Beton Spring is a water source used for fulfilling the basic needs of domestic activities, irrigation, and fisheries. Concerning water resources, it is particularly unique in that its upper course is an allogenic river with enormous groundwater potential. This research was intended to study the temporal water quality at Beton Spring. For this reason, the spring water was sampled periodically for one year. The water quality was assessed according to the drinking water quality standards, namely Regulation of the Minister of Health of the Republic of Indonesia No. 90 of 2002 and the standards set by experts. The analyses of trilinear and rectangular Piper diagrams were performed in Easy Quim v5.0 software. The analysis results showed that, temporally, the spring water had good quality because almost all samples collected in the dry and rainy seasons met the standards. The trilinear Piper diagram revealed that the Beton Spring mainly contained unpolluted and calcium-enriched groundwater. Meanwhile, the rectangular Piper diagram indicated the abundance of average bicarbonate waters, with only a few samples categorized into cation exchange-controlled groundwater.

O EFEITO DA QUALIDADE DA ÁGUA NO ENTUPIMENTO DE  EMISSORES E NO DESEMPENHO DE FILTROS UTILIZADOS NA IRRIGAÇÃO POR GOTEJAMENTO   Túlio Assunção Pires Ribeiro; José Euclides Stipp Paterniani; Rogério Pereira da Silva Airoldi; Marcelo Jacomini Moreira da SilvaDepartamento de Água e Solo, Faculdade de Engenharia Agrícola, UNICAMP, Campinas, SP, [email protected]   1 RESUMO  O presente trabalho teve como objetivo proceder a investigação experimental de uma fonte hídrica superficial, utilizada em um sistema de irrigação por gotejamento, bem como verificar sua influência na obstrução dos gotejadores e no desempenho de dois filtros um de disco e outro de mata sintética não tecida. A água de irrigação foi clorada, empregando-se hipoclorito  de sódio. Utilizou-se água provinda de um reservatório aberto, onde foi instalado um módulo de irrigação localizada para o estudo.  Analisou-se a variação temporal da qualidade da água durante um ano, onde considerou-se os principais parâmetros físicos, químicos e biológicos da água que causam problemas de entupimentos nos emissores. O desempenho dos filtros foi feito através da comparação das concentrações dos efluentes dos filtros de disco (usualmente utilizado para este fim) e manta sintética não tecida,  em relação aos parâmetros físicos e biológicas. O grau de obstrução dos emissores foi avaliado através de ensaios de vazão que determinaram a uniformidade de distribuição da água através de dois índices, onde variou-se o número de emissores amostrados.  A pesquisa foi desenvolvida em quatro etapas de 30 dias, realizadas em diferentes estações do ano. Os resultados apontaram na água de irrigação, que os parâmetros químicos pH e o ferro apresentaram médio risco de entupimento e sulfetos de hidrogênio mostraram alto risco de entupimento.  Não houve uma diferença no desempenho do filtro de manta e de disco com relação aos parâmetros físicos e biológicos de seus efluentes.  Os valores das médias dos índices de uniformidade de distribuição de água foram bem próximos para as duas parcelas que utilizaram os dois filtros de manta e disco.  UNITERMOS: irrigação localizada, índice de uniformidade, filtração, manta sintética não tecida, tratamento químico  RIBEIRO, T. A. P.; PATERNIANI, J. E. S.; AIROLDI, R. P. da S.; SILVA, M. J. M. da THE WATER QUALITY EFFECT IN THE CLOGGING OF EMITTERS AND THE PERFORMANCE OF FILTERS UTILIZED IN THE TRICKLE IRRIGATION  2 ABSTRACT  The present work aimed to carry out an experimental investigation of a superficial water source utilized in trickle irrigation as well as verify its influence in the clogging of drippers and in the performance of two filters: a disc one and a non woven synthetic one. The irrigation water was chlorinated with sodium hypochlorite. The water used in this experiment was from an open reservoir where an experimental trickle irrigation system was installed. The temporal variations of the water quality was assessed for one year, considering the main physical, chemical and biological parameters of the water that causes clogging in the emitters. The filter performance was assessed by comparing the effluent concentration in the disc filters (normally used for this purpose) and in non-woven synthetic fabric, for physical and biological parameters. The emitter obstruction degree was assessed through flow tests which determined the uniformity of water distribution through two rates where the number of sampled emitters varied. The research was developed in four 30-day stages, carried out in different seasons of the year. For the irrigation water, the results indicated that the chemical parameters (pH) and iron showed a medium risk of clogging whereas hydrogen sulphites showed a high risk of clogging. There was not a difference in the performance of fabric and disc filters in relation to physical and biological parameters of their effluents. The average values for  water distribution uniformity rates were pretty close for the two blocks that utilized both disc and fabric filters.  KEYWORDS: trickle irrigation, uniformity index, filtration, non-woven synthetic fabrics, chemical treatment

Abstract Periodic quality assessment of drinking water sources is necessary to guarantee the quality and security of water supply to people. Accordingly, this study assessed the drinking water quality of spring water of some villages located in Barwari Bala region of Duhok Governorate, Kurdistan region, Iraq, using the water quality index (WQI). To realize this objective, 120 spring water samples were collected from ten villages during the dry and wet seasons in 2018 and were analyzed for major physicochemical characteristics, including: calcium (Ca2+), magnesium (Mg2+), sodium (Na+), potassium (K+), chloride (Cl−), sulfate (SO42−), nitrate (NO3−), pH, total dissolved solids (TDS), turbidity, total hardness (TH) and total alkalinity (TA). The results for pH, turbidity, sodium, potassium, chloride, sulfate and nitrate showed that the water samples at all the sampled springs were suitable for drinking and within permissible limits based on given standards. However, TDS, TA, calcium and magnesium exceeded the permissible limits at some sites. It was also observed that, except for SO42−, at almost all the sites, the majority of parameters were significantly greater during the wet season compared to the dry season. With reference to all the parameters, the WQI values ranged from 10.76 to 18.13 during the dry season and from 17.10 to 20.45 during the wet season, indicating that all water samples are classified as having “excellent” water quality for drinking purposes. The calculation of WQI based on specific parameters, where values were close to or exceeded the maximum acceptable limits, showed that the water quality status of all water samples was “good” quality, except for sites S6 and S8, which were classified as “poor” quality and are not considered suitable for drinking purposes without treatment. Water from almost all the sampled spring sites can be considered as suitable for drinking purposes, although some parameters exceed permissible limits. Simple filtration treatment of the sampled spring water before use is desirable for ensuring good quality and security of the water supply to people of these areas.

Flow moving slowly (infiltration), and known as steady flow or baseflow is the only supplier of water in underground flows in the form of karst fields during the dry season. Certainly, the character contribution of this flow plays a major role in supporting the supplier of clean water. Understanding related to the character of baseflow in detail has a very high urgency to be studied. This Research aims to do a temporal analysis of baseflow contributions on epikarst water springs in Gunungsewu Karst Area, Indonesia. The research takes place in Guntur Springs that occupy the hydrogeological subsystem. Data used in this Research includes flow data from Guntur Springs for one year. The method used in this Research is automated base flow separation by digital filtering. Results of the analysis show that baseflow contribution in Guntur Springs are between 79.57% and 93.96%.

Source protection is part of a multi-solution approach for the provision of safe drinking water. In the Republic of Ireland, community-led Group Water Schemes (GWS) provide treated drinking water to approximately 69,000 rural households. Between 2009 and 2019, preliminary source protection assessments were undertaken for 70 GWS abstracting from surface water sources to provide physical catchment characterisation and untreated and treated water quality analysis. Catchment areas upstream of abstraction points varied in size, with 51.5% being less than 5 km2 and only 10.7% being larger than 100 km2. The majority (91%) of assessed GWS serve a population of less than 3000 people, and 94% supply less than 1500 m3 per day. Exceedances of the EU Drinking Water Regulations were recorded for 27 parameters, with the greatest number of exceedances due to total trihalomethanes followed by microbial contamination. The most frequent recommendation for improving GWS drinking water quality was associated with managing livestock access to local water bodies. Improving stakeholder engagement represented 38% of all recommendations made. Drinking water source protection measures and catchment-scale actions can be an additional model to assist in the delivery of Integrated Catchment Management and river basin management planning in the Republic of Ireland. For the GWS sector, challenges lie in securing resources to improve both source water and drinking water quality to deliver integrated catchment management plans for source protection.

As a small island and tourist destination, Karimunjawa municipal is need fresh water to support the tourist activity, mainly to supply drinking water. Unfortunately, freshwater on a small island is obtained from groundwater which is very limited and vulnerable to climate change and anthropogenic activities. A groundwater assessment is necessary to receive up-to-date information on groundwater quality, to assess the groundwater feasibility for drinking water, and determine the pollutant source. The assessment was conducted by collected groundwater sampling from dug wells and swamp area in Karimunjawa municipal and then analyzed the samples in the laboratory to obtain the value of Nutrient (NO3-, NO2-, NH3-N); Heavy Metals (Cu, Fe, and Pb); and Salt (TDS, Cl-, Na+). These obtained parameters were compared with the quality standard of the minister of health regulation of the Republic of Indonesia about water quality standards for drinking water. In this study, 14 samples were collected and analyzed. The result shows that nutrient contaminant is low, but some groundwater sample was contaminated by ammonia. Heavy metal is undetectable, but almost all samples are contaminated by salt. Therefore, the groundwater in Karimunjawa municipal experienced seawater intrusion and not feasible to be consumed as drinking water.
