Water shortage is a common problem in the high density settlement along the riverbank of Ciromban and Cibeureum River, Tasikmalaya, as the quality of the water also decreases. One of the solution is to maximize the use of river water. This study aims to investigate the interaction between river and groundwater along the riverbank as a function of land use impact. A river water and unconfined groundwater level mapping has been conducted to make water flow map, assuming both waters are in the same flow system. Physical parameters, temperature, TDS, and pH were measured at each stations to understand water characteristics. Based on observations at 50 dug wells and 12 river stations on July-August 2014, a close interaction between both water bodies has been identified with two flow systems: effluent flow (or gaining stream) at Cibereum river segment and influent flow (losing stream) at Ciromban river segment. Physical parameters show a high correlation in temperature, pH, and TDS. Hence, further evaluation from health point of view should be taken before using river water as raw water supply in Tasikmalaya area.

Study on raw water coagulation process for potable water production in the post-tsunami disaster areas district aceh besarThe coagulation – flocculation process in potable water treatment is very important to be studied in greater detail, since it has a very major impact on subsequent water purification processes and the quality of the water product. Types of coagulant that are commonly used are aluminum sulfate (alum) and poly-aluminum chloride (PAC). The objective of this research was to determine the optimum coagulant type and concentration to be applied for the treatment of surface water in post-tsunami disaster areas. This research is urgently required to design clean water installation in such area. Jar test of coagulants was performed to measure the efficiency of coagulation and sampling interval. From the obtained results, it can be concluded that the raw water turbidity influences the sedimentation time. At turbidity below 15 NTU, the optimum sedimentation time was 5 minutes. At turbidities above 15 NTU, the sedimentation was quicker, namely 1 minute. Based on jar test results on Krueng Raya river water, it can be observed that this river water can be treated with aluminum sulfate coagulant at 20 ppm dose. When PAC coagulant was used, the optimum dose was 15 ppm.Keyword: coagulant, efficiency, coagulation, water quality.AbstrakProses koagulasi flokulasi dalam pengolahan air minum sangat penting untuk ditinjau lebih jauh karena mempunyai pengaruh yang sangat besar terhadap proses purifikasi air berikutnya dan kualitas air produksi. Jenis koagulan yang sering dipakai adalah alumunium sulfat (alum) dan poly alumunium chloride (PAC). Tujuan penelitian ini adalah untuk menentukan tipe dan konsentrasi optimal koagulan yang diaplikasikan pada air baku berupa air permukaan di wilayah bencana pasca tsunami. Hal ini sangat diperlukan untuk membuat perencanaan rancangan instalasi pengolahan air bersih di wilayah tersebut. Jar test koagulan dilakukan untuk menentukan efisiensi koagulasi dan waktu sampling. Dari hasil penelitian ini dapat disimpulkan kekeruhan air baku mempengaruhi waktu sedimentasi. Pada kekeruhan di bawah 15 Nephelometric Turbidity Unit (NTU), waktu optimum sedimentasi adalah lima menit, tetapi pada air baku yang kekeruhannya di atas 15 NTU, waktu sedimentasi lebih cepat yaitu satu menit saja. Dari hasil jar tes yang dilakukan terhadap air di sungai Krueng Raya dapat dilihat bahwa air sungai Krueng Raya dapat diolah dengan bahan koagulan aluminium sulfat pada dosis 20 ppm, sedangkan jika menggunakan bahan koagulan PAC memerlukan dosis optimal 15 ppm.Kata kunci : koagulan, efisiensi, koagulasi, kualitas air

Hydrogeochemical and isotopic composition of river and groundwater in Kandi and Sirowal belts of Jammu District in the Union Territory of Jammu and Kashmir was carried out to understand the recharge source and chemical nature of these waters for drinking water quality criteria. Physical parameters (temperature, pH, Total dissolved solids, total hardness and electrical conductivity), major cations and anions (Ca2+, Mg2+, Na+, K+, HCO3-, Cl-, SO42-, NO3-) and stable isotopes (d18O and d2H) inTawi river and groundwater samples from hand pumps and tube wells were measured. The dominant cation is Ca2+ and the dominant anion HCO3- implyingCaHCO3type water in both river and groundwater. To assess the quality of water for drinking purposes, Groundwater Quality Index (GWQI) has been calculated. The GWQI indicates that Kandi and Sirowal belts are showing “Excellent” to “Good” category for drinking purposes. The stable isotopic composition of river water and groundwater is indicative of meteoric origin and enrichment before groundwater recharge. The stable isotopes in water suggest that the active canals in Sirowal belt,and rainfall and river water near the banks in Kandi belt contribute to ground water recharge.

Results are presented from a field study performed on the Ciliwung, Sunter and Krukut Rivers in Jakarta. The rivers are used as raw water sources for Jakarta municipal water supply systems, yet the rivers are used as receiving bodies by some inhabitants and industries. In this study, the quality of the rivers' water was determined using a Water Quality Index (WQI) which is scaled from zero to a hundred. The higher number of the WQI indicates, the better quality of the river water. Among the results presented are the WQI and heavy metals concentration. River water sampled from upstream of Jakarta, intake areas, and estuary areas were tested during the dry and rainy seasons. In the dry season the WQIs of Ciliwung, Sunter and Krukut Rivers ranged between 21-42, 20-29 and 21-38, respectively. In the rainy season the WQIs of Ciliwung, Sunter and Krukut Rivers ranged between 34-47, 32-50, and 34-47, respectively. The level of heavy metals did not exceed current Indonesian Standards. It was concluded that the overall water quality of the Ciliwung, Sunter, and Krukut Rivers was between very poor and poor, and the rivers were polluted by Cu, Pb, Cd, Zn and Hg.

Imbalance of supply and demand is the beginning of a scarcity of clean water. To detect the occurrence of water scarcity needed calculation of water demand to estimating water source to be used. Water scarcity occurs due to natural factors associated with limited sources of raw water to water drinking, the system performance of water supply services are inefficient and increasing of water demand. The high level of leakage, inefficient processing, and low of coverage service from PDAM are performance factors that is causing water scarcity. Meanwhile, population growth and development of the region is demand side factor which led to the scarcity of water. Shortage of safe drinking water to the community caused by the condition of water management is not optimal. This is demonstrated by the leakage rate is still above the standard that tolerated (20%), a relatively small customer coverage is 15.69% of the population that has been underserved by the piping systems, idle capacity because of unoptimal instalation. Scarcity can anticipate with three ways: (1) increasing quantity and quality of raw water, (2) save the use of water and recycle waste water, (3) decrease of leakage, improve PDAM performance, and efficiency of water treatment.
