The focus of this work is on the evaluation of selected water quality indicators as per the applicable regulations, taking into account European and national legislation and the evaluation of the risk of contamination of surface waters with toxic elements using the contamination factor (Cfi) and the degree of pollution (Cd). The studied area of Slovinky is an important ore region, with rich deposits of copper and silver ores that have been mined for centuries. One of the most important remnants of mining activities in this area is the Slovinky tailing impoundment. The sludge pond area has an area of 15 ha, and the height of the dam is 113 metres above sea level, which makes the sludge pond one of the tallest water structures in Slovakia. The Slovinský creek was monitored in the years 2010, 2011, and 2019 at five sampling points, which were selected to map the entire length of the water flow from the source to the estuary to the river Hornád. Risk elements (As, Cu, Cd, and Fe) and physicochemical parameters (such as temperature, dissolved oxygen concentration, conductivity, resistivity, salinity, total dissolved solids, NaCl, redox potential, and pH) were included in this study and evaluated according to applicable regulations, taking into account European legislation (Act No. 269/2010 Coll., guideline value WHO 2011). The results of the experimental studies showed that the highest values of As and Cu were measured at the site where drainage waters from the Slovinky tailing impoundment and mining water of the Alžbeta shaft flow into the creek. The concentration of As exceeded the limit value by up to 31 times and the concentration of Cu 16.8–134.5 times. At the same time, the highest values of conductivity, salinity, total dissolved solids, and NaCl were found, and there was no acidification of water at the site that had the highest pollution. Water contamination was assessed based on Cfi and Cd; our findings showed that the surface water from the site of contamination, along the entire length of the stream, was very highly contaminated with risk elements in the order of As > Fe > Cu, and the level of contamination decreased with distance from the site of contamination. Our research shows that seepage of toxic substances from sludge ponds and abandoned mines has caused the requirements for the quality of surface water of the Slovinský creek not to be met. In connection with mining activities, surface streams act as a transport medium through which other components of the environment can be polluted.

Abstract The objective of the study was to assess the quality of the Shule River water for irrigational purposes. Surface water samples were collected along the course of the river in May and October 2012. The samples were analyzed for pH, electrical conductivity (EC), bicarbonate, chloride, sulphate, sodium, potassium, calcium and magnesium. Surface water was generally alkaline (average pH 8.17) and water pH and total dissolved solids in May were higher than those in October. EC ranged from 0.24 to 2.15 mS cm−1. Sodium was identified as the dominant cation, sulphate was identified as the dominant anion in May for both samples of river water but, in October, the dominant anions are respectively sulphate, bicarbonate and chloride from the upper region to the lower region. The total dissolved solids, chloride and sodium were found to exceed the permissible limits for irrigation water in the lower region. According to the principal factor analysis results, among water quality parameters measured in this study, chloride is the best indicator for monitoring water quality. The results revealed a deteriorating water quality in the lower region of the river.

ABSTRACTSerang District is one of the flood-prone areas, that about 20 subdistricts were affected by the flood in Serang District. Problems of clean water necessity occurred in the flood area, especially water quality in both of surface water and groundwater. To know the condition of clean water in Serang District, it is necessary to study the quality of water both surface water and groundwater in the flood-prone areas. The study was conducted by water sampling and in-situ water quality measurements at 28 open-pit points used by communities and river bodies in the potential flood in 2012-2015. In-situ physical water quality measurements are performed during sampling of well water and river water using multiparameter quality checker equipment. Water quality parameters that were measured in-situ are total dissolved solids (TDS) and turbidity. Laboratory tests of water samples were performed for suspended solids (TSS), Ammonium (NH3-N), Iron (Fe), Manganese (Mn) and total hardness parameters. The standard method of water quality analysis of these parameters is carried out using Indonesian National Standard SNI 06-6989.3-2004 water and wastewater. Turbidity tends to increase towards the downstream of the river indicating additional sediment material is transported downstream. The high total suspended solids in the river, especially in Kragilan, is caused by the waste from high domestic, commercial, and industrial activities in the area. Generally, groundwater and surface water in the flood areas at the study sites still largely indicate that quality is still feasible for consumption by the community, except for high Fe and Mn content and NH3-N in some wells due to the influence of surface water entering groundwater.Keywords: Serang district, water quality, flood areas, water supply ABSTRAKKabupaten Serang termasuk wilayah yang rawan banjir, dari 29 kecamatan yang ada sekitar 20 kecamatan pernah terkena dampak banjir. Permasalahan kebutuhan air bersih terjadi pada kawasan banjir tersebut, terutama kualitas air baik air permukaan maupun airtanah. Untuk mengetahui secara rinci kondisi air bersih di kabupaten Serang, maka perlu dilakukan kajian kualitas air baik air permukaan maupun airtanah pada kawasan rawan banjir tersebut. Kajian dilakukan dengan pengambilan sampel air dan pengukuran in-situ kualitas air pada 28 titik sumur terbuka yang digunakan oleh masyarakat dan badan air sungai pada wilayah potensial genangan banjir tahun 2012-2015. Pengukuran kualitas air fisik secara in-situ dilakukan pada saat pengambilan sampel air sumur dan air sungai dengan menggunakan peralatan multiparameter quality checker, adalah: zat padat terlarut (total dissolved solids/TDS) dan turbiditas/kekeruhan. Sedangkan pemeriksaan laboratorium terhadap sampel air dilakukan untuk parameter zat padat tersuspensi (total suspended solid/TSS), Amonia bebas NH3-N), Besi (Fe), Mangan (Mn) dan kesadahan total. Metode standard analisis kualitas air terhadap parameter-parameter tersebut dilaksanakan menggunakan Standard Nasional Indonesia SNI 06-6989.3-2004 air dan air limbah. Kekeruhan cenderung meningkat ke arah hilir sungai menunjukkan adanya tambahan material sedimen tertransport pada bagian hilir. Tingginya zat padat tersuspensi pada sungai khususnya di Kragilan akibat dampak limbah dari aktivitas domestik, komersial dan industri yang tinggi di daerah tersebut. Secara umum airtanah dan air permukaan pada daerah banjir di lokasi penelitian sebagian besar masih menunjukkan kualitas yang masih layak untuk dikonsumsi oleh masyarakat, kecuali kandungan Fe dan Mn yang tinggi serta NH3-N pada beberapa sumur penduduk akibat pengaruh air permukaan termasuk air banjir masuk ke dalam airtanah.Kata kunci: Kabupaten Serang, kualitas air, kawasan banjir, penyediaan air bersih

Groundwater Surface Water Interaction

Abstract. Identifying areas of interaction between groundwater and surface water is crucial for effective environmental management, because this interaction is known to influence water quantity and quality. This paper applies hydrochemistry and multivariate statistics to identify locations and mechanisms of groundwater-surface water interaction in the pastorally dominated Wairarapa Valley, New Zealand. Hierarchical Cluster Analysis (HCA) and Principal Components Analysis (PCA) were conducted using site-specific median values of Ca, Mg, Na, K, HCO3, Cl, SO4 and electrical conductivity from 22 surface water sites and 246 groundwater sites. Surface water and groundwater monitoring sites were grouped together in three of the seven clusters identified by HCA, with the inference made that similarities in hydrochemistry indicate groundwater-surface water interaction. PCA indicated that the clusters were largely differentiated by total dissolved solids concentration, redox condition and ratio of major ions. Shallow aerobic groundwaters, located in close proximity to losing reaches of rivers, were grouped with similar Ca-HCO3 type surface waters, indicating potential recharge to aquifers from these river systems. Groundwaters that displayed a rainfall-recharged chemical signature with higher Na relative to Ca, higher Cl relative to HCO3 and an accumulation of NO3 were grouped with neighbouring surface waters, suggesting the provision of groundwater base flow to these river systems and the transfer of this chemical signature from underlying aquifers. The hydrochemical techniques used in this study did not reveal groundwater-surface water interaction in some parts of the study area, specifically where deep anoxic groundwaters, high in total dissolved solids with a distinct Na-Cl signature, showed no apparent link to surface water. The drivers of hydrochemistry inferred from HCA and PCA are consistent with previous measurements of 18O, water age and excess air. Overall, this study has shown that multivariate statistics can be used as a rapid method to identify groundwater-surface water interaction at a regional scale using existing hydrochemical datasets.

The most common methodology for removal of Cr(VI) in literatures is the combination of reduction and precipitation process. The disadvantages of this method are presence of high total dissolved solids in the treated water and sludge generation. In order to find a new solution, efforts have been focussed to convert Cr(VI) present in the groundwater, into the useful products like zinc chromate and barium chromate under appropriate conditions. The efficiency of these conversions is compared with the efficiency of the reduction and precipitation process adopted in this study, using sodium metabisulphite. These experimental studies were carried out with stimulated water containing 2000 mg/L of Cr(VI) and then extended to Cr(VI) contaminated groundwater with same concentration. The results are compared and validated through batch experiments.
