Opis:
The self-purification capacity of river water is an essential indicator for a healthy river. Various organic and inorganic pollutants, both from point sources and nonpoint sources, in most streams in Banjarmasin were beyond the river self-purification capacity, which caused a decrease in the river water quality. This study attempted to identify the river water pollution distribution in the city of Banjarmasin and determined the self-purification points. We used the purposive sampling technique to carry out river water sampling, with criteria for pollutant sources and distance of pollution taken into consideration. By using the trend analysis techniques, we analyzed the parameters concentration to relate it to the range of pollution so that we were able to identify the pollution distribution and determine the self-purification distances. The results indicated that the self-purification process could take place on the river flow in of Banjarmasin even though it did not reach the clean water zone. The river in Banjarmasin requires a longer purification distance so that the self-purification process can run correctly.

Opis:
The Cisadane River, Tangerang City, is one of the most important rivers in Indonesia. This river provides raw water for Municipal Waterworks (PDAM) of the Tangerang City and Soekarno-Hatta International Airport, but the water quality tends to deteriorate due to pollution. The government has made various efforts to manage the river water quality, but no significant resolution was issued yet. The problem is becoming more complicated due to land-use changes that affect the pollutant load. Therefore, more precise, integrated, and comprehensive management is needed. This study used an approach with various methodologies according to the stages of the research, including; qualitative and quantitative analysis, GIS, statistics, risk management, and System Dynamic. The outcome of this research was the development of the policies in river water quality management, specifically land use manage-ment, separation of drainage channels from domestic sewage channels, enhancement of Wastewater Treatment Plant (WWTP) services coverage, as well as reinforcement of institutional and regulatory aspects, especially in funding commitments.

Opis:
The main purpose of the study was to evaluate water quality of the Supraśl river and identify its main pollution sources. On the river and its tributaries, 8 control points were selected, located near Krynica, Gródek, Nowosiółki, Zasady (mouth of the tributary Sokołda), Supraśl, Nowodworce, Dobrzyniewo (mouth of the tributary Biała) and Dzikie. The control points were selected in such a way as to take into account the impact of major point sources of analyzed components located along the river and its main tributaries on water quality in the main stream catchment. Water samples were collected once a month during the period from May to November in 2014. In water samples the concentration of dissolved oxygen, Cl-, SO42-, N-NH4+, P-PO43- and the values of pH, BOD5 and electrolytic conductivity were indicated. Based on the obtained results, loads of the individual components in river waters were calculated as a product of concentration and Supraśl waters flow rate in a particular month. Supraśl waters, due to values of most analyzed parameters, should be classified as first quality class. The source of Cl-, SO42-, N-NH4+ in Supraśl waters were treated wastewater and other anthropogenic sources associated with the basin development. Reduced Supraśl water quality is caused by the inflow of organic substances expressed by BZT5 from natural and anthropogenic origin and concentration of PO43-, which were mainly delivered with treated wastewater.

Opis:
W pracy określono wpływ wód kopalnianych na jakość Potoku Goławieckiego (woj. śląskie), który jest odbiornikiem wód dołowych kopalni "Ziemowit". Badaniami objęto około 900 m odcinek biegu potoku znajdujący się poniżej zrzutu wód dołowych z osadnika ziemnego. W okresie od czerwca do grudnia 2002 r przeprowadzono 7 poborów próbek wody, w których na miejscu oznaczono temperaturę, tlen rozpuszczony, pH i mętność, natomiast w laboratorium -zawartość zawiesin, jonów siarczanowych, chlorkowych i substancji rozpuszczonych. Ocena jakości wody z Potoku Goławieckiego wykazała, iż rzeka znajduje się pod silnym wpływem wód dołowych. Duża mętność wody oraz ponadnormatywna zawartość zawiesin, chlorków i siarczanów klasyfikują wody odbiornika do V klasy czystości. Wykazano, że znaczna ilość zasolonych wód dołowych, w stosunku do średniego niskiego przepływu w odbiorniku tych wód, nie pozwala na utrzymanie dopuszczalnej zawartości chlorków i siarczanów w wodzie z Potoku Gołowieckiego. Przeprowadzone badania wykazały, że charakter hydrochemiczny Potoku Goławieckiego jest współkształtowany przez zrzuty wód kopalnianych, które przyczyniają się do zakłócenia jego naturalnego reżimu wodnego.
The investigations covered an approximately 900-meter length of the recipient downstream from the points of drainage water discharge from a settling pond. Samples were collected seven times between June and December 2002. Temperature, pH and turbidity were measured in situ; the concentrations of suspended solids, sulfate ions, chloride ions and total dissolved substances being determined under laboratory conditions. The findings produced by the study can be itemized as follows. (1) The mine water discharge strongly impacts upon the recipient. (2) Owing to a high turbidity level, as well as to the excessive concentrations of suspended solids, chlorides and sulfates, the Potok Golawiecki has been classified as a watercourse of Class V purity. (3) The large amount of the high-salinity waters received by the Potok Golawiecki, compared to their mean low flow in the recipient, does not allow the concentrations of chlorides and sulfates to be kept within the admissible levels. (4) The discharge of drainage water is a major contributor to the hydrochemistry of the recipient stream, thus disturbing its natural regime.

Water quality index (WQI) is valuable and unique rating to depict the overall water quality status in a single term that is helpful for the selection of appropriate treatment technique to meet the concerned issues. The aim of the study was to evaluating water quality from Mojen River by Water Quality Index based on National Science Foundation (NSFWQI). For this purpose, samples were collected from stations at up, middle and downstream of Mojen River in Semnan province (the biggest river in region) in a 2 years interval of 2013-2014 years. Nine parameters namely Turbidity, Biochemical Oxygen Demand, Dissolved Oxygen, Fecal Coliform, nitrate, pH, temperature, total solids and total phosphate were considered to compute the index. Our findings highlighted the deterioration of water quality in the river due to industrialization and human activities. According to NSFWQI, the best condition was recorded in the Dark haniab (Upstream) and the worst condition concerned the Pole (Midstream).

Opis:
Mining is an important economic activity in Kosovo. Artana and Kishnica mines are a part of the Trepça industrial complex and the increased exploitation of deposits has resulted in undesirable impact on the environment around the mining sites. More specifically, the mining activity caused water pollution. The aim of the study was to assess the physico-chemical parameters and presence of heavy metals (Ni, Zn, As, Cd, Pb, Cr, Mn, Fe) in water samples of the Graçanka River and household wells in the area. The Inductively Coupled Plasma-Mass Spectrometer (ICP-MS) was used to determine metal concentrations. Samples were collected from five sites along the Graçanka River and from four private water wells during a period from September to November 2019. Concentrations of heavy metals in the Graçanka River were as follows Mn (24–1203 μg∙dm–3), Fe (11–785 μg∙dm–3), Ni (4–299 μg∙dm–3), Pb (2–22 μg∙dm–3), As (1–5 μg∙dm–3), Zn (344–1646 μg∙dm–3), Cr (1–2 μg∙dm–3) and Cd (<1 μg∙dm–3). The well waters were polluted by multiple metals (Mn > Fe > Ni > Pb) with concentrations of Mn 1834–36089 μg∙dm–3, Fe 158–3535 μg∙dm–3, Ni 82–1882 μg∙dm–3, Pb 5–45 μg∙dm–3, As 2–19 μg∙dm–3, Cd 1–12 μg∙dm–3, Zn 979–23474 μg∙dm–3 and Cr 1–2 μg∙dm–3. The pollution has been caused by industrial (mining-related) and urban discharges. The contamination originates from the release of flotation process waste and from the leaching of the tailings dam. Most probably, rainwater has washed contaminants into the aquifers and the Graçanka River. River water is not suitable for irrigation and well water is not suitable for consumption or irrigation. Wastewater should be treated before discharge and the tailings area should be remediated in order to stop the pollution.

The measurements of chemical components in water of Wieprza River showed that water of this river in 2002-2003 was characterised by the high purity. The average values of most indexes were contained in the ranges of standards for the first purity class. Nevertheless considerable increase of investigation parameters was observed in zone of sewage-treatment plant and uncontrolled waste dump. The part of flow downing pollutions were absorbed by peat soils. Kępice town bring into Wieprza River the load of organic matter miscalculating to BOD5 average 133 kg O2 d-1 (85 t O2 y-1), the load of nitrogen 140 kg N d-1 (51 t N y-1) and phosphorus 18 kg P d-1 (6.2 t P y-1). However Wieprza River shows high self-purification ability. The level of investigation components in this river (4 km outside of the Kępice town) returned to the level which was 2 km before the town.
Określenie składu chemicznego wody w rzece Wieprzy pozwoliło stwierdzić, że wody tej rzeki charakteryzują się dużą czystością. Większość analizowanych składników mieściła się w granicach norm dla I klasy czystości. Niemniej jednak w rejonie oczyszczalni ścieków i niekontrolowanego wysypiska odpadów obserwowano znaczny wzrost badanych parametrów. Badania gleb torfowych wykazały, że część spływających ku rzece zanieczyszczeń jest absorbowana przez te gleby. Oszacowano, że miasto Kępice, przez które przepływa rzeka Wieprza, wprowadza do niej ładunek materii organicznej, w przeliczeniu na BZT5, średnio 133 kg O2 d-1 (85 t O2 r-1), ładunek azotu 140 kg N d-1 (51 t N r-1) i fosforu 18 kg P d-1 (6,2 t P r-1). Jednak rzeka Wieprza wykazuje duże zdolności samooczyszczające, ponieważ około 4 km za miastem poziom badanych składników wody powraca do wartości, jakimi charakteryzowały się wody tej rzeki 2 km przed miastem.

Opis:
The concentrations of zinc and cadmium were determined in the sediment cores sampled from the floodplain and the channel in the middle reach of the Biała Przemsza River valley (southern Poland). The results were compared to the river water and groundwater chemistry in order to reveal the average extent of the hyporheic flow. The loss of river waters through the river bed due to the natural migration modified by the drainage of the lead-zinc ore mine caused the strong pollution of the river bed sediments with heavy metals to the depth of almost three meters below the water table in the river. Moreover, the similar groundwater and river water chemistry at that depth suggests that the vertical extent of the hyporheic zone, which exceeds a depth of several meters below the channel, can be affected by the drainage of river waters by the lead-zinc mine. The lateral extent of the hyporheic flow, indicated by changes in groundwater chemistry and elevated heavy metal concentrations in the sediments, was of the order of dozen of meters. The investigation documents the large impact of the secondary in situ enrichment of sediments with heavy metals in the hyporheic zone.

The aim of this paper was to evaluate the influence of anthropogenic pollution on the water quality of the Ciemięga River, which flows through the Jastków commune, located in the Lublin Province in the South-Eastern Poland. The analyses of the river water were conducted in the years 2019–2020. Each year, the samples for physicochemical analyses were collected seasonally (in February, May, August and November) from the seven selected Ciemięga River sampling points found in the following localities: Ożarów, Moszenki, Sieprawice, Jastków, Snopków and Jakubowice Konińskie. In addition, 3 series of microbiological analysis were conducted in 2020. Electrolytic conductivity, total phosphorus, nitrate-nitrogen and sulfates constituted the physicochemical indicators of poor water quality in the river. Their average values exceeded the standards for the 2nd class of water quality. High concentration of these indicators, especially of the total phosphorus, could have been related to the influx of domestic wastewater from agricultural holdings, wastewater flows from agricultural areas as well as soil erosion and leaching. The levels of E. coli bacteria and fecal coliform allocated the Ciemięga River waters to the 4th class of water quality and could result from domestic wastewater flow to the river. In order to improve the water quality of the Ciemięga River, it is necessary to reduce or eliminate point and non-point sources of pollution by means of streamlining of the agricultural areas fertilization, regulating the water and wastewater management, regulating of the waste management, as well as the appropriate spatial policy and landscaping of the water catchment areas.

As a result of this, the water in the river for these substances was rated as “dirty” in terms of purity and corresponded to water quality class IV, namely: phosphorus was observed to exceed the MPC at the observation point Ambukіv village in 2015 (9.7 times), for manganese – an excess of the MPC at the observation point Ambukіv village in 2018 (9.7 times) and in point Zabuzhzhia village in 2014 (7.9 times), 2015 (8.0 times), 2017 (7.1 times), 2018 (8.3 times); for the total iron – the exceeding of MPC at the observation point Ambukіv village in 2016 (5.95 times) and 2017 (6.13 times); at the observation point Ustilug town in 2016 (5.23 times); in the observation point Zabuzhzhia village in 2016 (9.44 times) and 2017 (5.27 times). The assessment of the surface waters based on the determination of the pollution factor showed that during the study period their quality did not deteriorate but did not meet the norms. In general, surface waters of the river correspond to the second class of quality and are characterized as “poorly polluted” waters by the level of pollution.

The pollution of rivers is an important issue because the utilization of polluted water has a direct effect on the health of people and other living beings, economy, etc. Sediments represent a very suitable indicator for monitoring and detecting pollution sources of river waters. The aim of this study is to analyze the contents of selected metals in the sediments of the rivers Likova, Kumanova and Pçinja rivers. The water samples were taken in June 2014 from six sampling stations. Several physicochemical parameters of rivers were determined and the contents of twenty-two metals was indicated in the sediment samples taken from these rivers. The obtained physico-chemical quality of the water from these rivers resulted in classification to the first/second category. The sediments were mostly polluted by Al, Ca, Na and Mg. The metals that exceeded the Dutch standard were: Ba, Ni, Zn, Cr and Cu. The order of metals in sediments was as follows: Fe > Al > Ca > Na > Mg > K > Mn > Ba > Sr > Cr > Zn > V > Ni > Cu > Pb > Li. The study results reveal a mild pollution in rivers caused by urban, agricultural and industrial activities.

Opis:
The results of five-year (2008–2012) hydrochemical research of the Poprad river, the right bank tributary to the Dunajec, were analyzed in the paper. The Poprad, 167 km long and with the catchment area of 2077.3 km2, flows for over 100 km through the territory of Slovakia, along the length of 31.1 km is a transboundary river, whereas its 31.0 km long reach is situated in Poland. Concerning its abiotic character, it is an eastern upland river of type 15. The research was conducted in three measurement-control points: 1) located in Leluchów on the Polish-Slovak border at 61.1 kilometer of the river course, 2) in Piwniczna-Zdrój – 23.9 km and 3) in Stary Sącz – 2.9 km before the Poprad outlet to the Dunajec. 21 physicochemical indices and 2 microbiological indicators were assessed in the water samples once a month using referential methods. The paper assesses changes of water quality classes and its usable values along the analyzed Poprad river reach. Moreover, statistical differences between the values of individual indices assessed in various measurement-control points were estimated by means of Mann-Whitney U nonparametric test. On the basis of the conducted analyses of the empirical data it was stated that due to the physicochemical indices, water quality along the whole length of the analyzed river reach was good (class II) – in points 1 and 3 it was determined by mean concentration of total suspended solids, whereas in point 2 COD-Mn values.

Opis:
The Timok River (202 km long, 4547 km2 basin area) is located in East Serbia. It is a right tributary of the Danube River and one of the most polluted watercourses in Serbia. On the basis of the data provided by the Republic Hydrometeorological Service of Serbia, the paper presents an analysis of water quality and pollution using the combined physico-chemical WPI index (Water Pollution Index) calculated for two periods - 1993-96 and 2006-2009 at four hydrological stations: Zaječar-Gamzigrad (Crni Timok River), Zaječar (Beli Timok River), Rgotina (Borska Reka River) and Čokonjar (Timok River). The following parameters were taken into consideration: dissolved O2, O2 saturation, pH, suspended sediments, Five Day Biochemical Oxygen Demand (BOD5), Chemical Oxygen Demand (CODMn), nitrites, nitrates, orthophosphates, ammonium, metals (Cu, Fe, Mn, Hg, Ni, Zn, Cd), sulphates and coliform germs. The average WPI values were calculated for the observed periods based on the comparison of the annual average values of the listed parameters and defined standard values for the I water quality class (according to the Regulation on the Hygienic Acceptability of Potable Water of the Republic of Serbia). The highest pollution degree was recorded in the Borska Reka River, where heavy metal levels (especially manganese and iron) were significantly increased. These metals are indicators of inorganic pollution (primarily caused by copper mining). Also, increased values of the organic pollution indicators (ammonium, coliform germs, Five-Day Biological Oxygen Demand - BOD5) in the Borska Reka and the Timok rivers are the result of uncontrolled domestic wastewater discharge.

Opis:
The dynamics of hydrochemical parameters of surface waters from the upper, middle and lower reaches of the river was analyzed. On the basis of the analysis of temporal and spatial monitoring data, a comprehensive assessment of the environmental status of the Inhulets river (Ukraine) waters by hydrochemical indicators was carried out. The study performed a comparative analysis of the river water quality assessment using different methods: an integrated assessment based on the calculation of water pollution indexes, pollution rate. A result of the evaluation of water quality in certain classes: in terms of ammonium ions and BOD5 – III quality class, the water is slightly polluted; phosphate content – V quality class, water is very low in the bottom; according to the content of suspended solids, in phosphates and BOD5 – III class of water quality, water is polluted; by a concentration of chlorides – V class of quality, degree of purity – very dirty; the value of suspended solids and chlorides – III class; in terms of the sulfate content – IV class. In general, the very excessive concentration of substances in the middle course remains stable, the environmental state is poor (quality class IV).
