Abstract:
Water is the basis of life and means must be put in place to check its quality for domestic purposes. The river Osse is one of the rivers located in Kabba, Kogi state, and it serves various purposes for the residents of its community. Water samples were collected from 3 stations of Osse river namely; Okoro, Odolu and ABU. These samples were accessed to determine if the water is suitable for domestic purposes. The results of the analyses of the water samples showed that the river had relatively good quality as the dissolved oxygen (DO2) was within the international and local standards i.e. world health organization (WHO) and Nigeria industrial standards (NIS) respectively. The highest value recorded was 0.60 mg/l at station 1 in August and the lowest value was 0.18 mg/l at the same station in May. The highest mean value for the Nitrate concentration of the river was 36.47 mg/l at station 3 and the lowest was 26.12 mg/l at station 2 and this still falls within the standards laid down. TDS, chloride, alkalinity were in the range of 29-70 mg/l, 3.15-30 mg/l and 16-20 m /l respectively and none was above the limit set down by WHO and NIS. The pH level of all the stations throughout the study ranged from 7.4-7.9 meaning they were also within standards. The BOD highest value was 3 and was also within the tolerance range for pure water. The result shows that the River Osse was within the WHO international standard and not above the standards of the local set limits by NIS. Thus, making the river fit and good for domestic purposes.

Abstract:
Currently, the issue of protecting natural resources from polluting and preventing pollution requires worldwide attention. In general, water resources are becoming an invaluable resource that explains the sustainable development of any state. Rational use and protection of water sources is becoming one of the most pressing issues in our country. Pollution of water sources, in turn, affects the deterioration of water quality, living organisms that live in water sources (algae, fish, etc.), and the health of consumers. Since water is the most important resource in the world, it is a task to protect and prevent environmental risk. Therefore, to monitor the aquatic ecosystems of Akmola region, the research team conducted research in laboratory conditions, taking water samples from water bodies (Nura, Ishim Riversand Taldykol, Maybalyk, and Zhaltyrkol Lakes) from a practical trip organized by the research group. Research studies on water samples taken from water bodies showed that the water was polluted, and in some indicators the maximum rural concentration was exceeded. It is clear that pollutants affect water biota, although in most cases they are not the cause. According to water samples, the level of pollution of water sources was assessed. Protection of Water Resources in general from pollutants is one of the strategic tasks of the country.

Abstract:
This article provides a deep analysis of the water quality at the upper basin of the Bogota River (Colombia) between 2008 and 2017. The Water Quality Index has been the indicator employed to determine the ecological status of the river. This index was chosen in order to normalize the analysis, given that it is commonly used by the Institute of Hydrology, Meteorology and Environmental Studies, a government agency of the Ministry of Environment and Sustainable Development of Colombia, to determine the state of surface effluents. The results obtained were organized in a double-entry matrix in order to relate the variables of the sample period and the sampling station. The research revealed an insufficient quality of water, demonstrating that the high stretch of the Bogota River basin has, in general, regular or acceptable water quality, while only five stations showed an acceptable status. Surprisingly, the stations located close to the wastewater treatment plants of the municipalities of Choconta, Suesca, Gachancipa, and Tocancipa, as well as Rio Negro, have a poor water quality, discharging a high load of contaminants into the river. Although great efforts have been made by Colombian authorities to restore the critical state of the majority of their aquatic ecosystems, recent implementation of policies and instruments have not shown significant achievements yet. For this reason, this study aims to present a powerful decision-tool for the monitoring and evaluation of correction measures implemented on this river basin. The data used in this research were provided by the Regional Autonomous Corporation of Cundinamarca.

Abstract:
Long-term studies (1998–2018) of shallow lakes Krugloe and Krutoe (Russia) were carried out. The trophic status of the lakes was estimated using physicochemical parameters of water and the indicators of zooplankton. Physicochemical studies of Krugloe and Krutoe lake water make it possible to classify these reservoirs as eutrophic according to their trophic status. The lakes are characterized by low water transparency, a high content of organic substances in water, the “blooming” of water is observed periodically, accompanied by the increase of pH to 8–9 units. The zooplankton communities of Krugloe and Krutoe lakes are characterized by relatively low species richness, the dominance of a small number of species, and the predominance of species that are indicators of eutrophic waters. Quantitative indicators of zooplankton are characterized by significant fluctuations in values over the years, the prevalence of rotifers. They showed that zooplankton community is a good indicator of the trophic state of lakes. Such indicators of zooplankton communities as the composition of dominant species, their number, the presence of indicator species, the quantitative indicators of zooplankton and individual taxonomic groups, and the average individual mass of the zooplankton can be used to characterize the trophic status of lakes. They can be recommended for use during monitoring of the lake condition in the Volga-Kama State Natural Biosphere Reserve.

Abstract Selulu Reservoir is located in Waru District, North Panajam Paser Regency. It is one of the tourist destinations in supporting the tourism sector. Land use changes and urbanization have potential impacts on the environment. This study aimed to determine Water Quality Status and Water Quality Index (WQI) in Selulu Reservoir. Hopefully, the result will become the basis for future reservoir management to keep the water quality well. The method in this study used the survey method. These research steps include surveys, water samples, laboratory analysis, and data analysis. Parameters analyzed include temperature, pH, BOD, COD, and DO. The results showed that the reservoir’s water quality in all samples still met the standard, except for pH at point 3. The difference fluctuating value found in COD at point 3, although it still meets the standard. This location is close to residential areas that dump their waste into the reservoir. The Water Quality Status of the reservoir still meets the standards, and WQI is in the excellent category. This is due to the dominant land use of forest and plantations with few settlements around the reservoir, domestic waste is small, and the reservoir capacity is still supportive. Management is needed to maintain reservoir water quality in the future.

RESUMO Este estudo avaliou a qualidade da água do reservatório Carlos Botelho, SP, Brasil, empregando a base de dados da Companhia Ambiental do Estado de São Paulo para os anos de 2017 a 2019. Foram utilizadas as concentrações de clorofila a e o número de células de cianobactérias, relacionando-os com o algoritmo de processamento de imagens da Agência Espacial Europeia. Foram utilizadas imagens dos satélites Sentinel 2, com resolução espacial de 10 m e correção atmosférica Case 2 Regional Coast Color. Os dados de clorofila a da Companhia Ambiental do Estado de São Paulo e os estimados pelo algoritmo apresentaram alta correlação (R²=0,6052, RNMSE=27%, n=8) e também se relacionaram estatisticamente com o número de células de cianobactérias, o que permitiu estimar o número de células de cianobactérias nas imagens S2, por meio das concentrações de clorofila. Com base nas estimativas, o reservatório Carlos Botelho apresentou padrão eutrófico em praticamente o ano de 2020; os dados sugerem a presença e substancial predomínio de cianobactérias em toda massa de água e durante todo 2020 (da ordem de 10.000 a 20.000 células.mL); na sua água já foi constatada a presença de cianotoxinas potencialmente tóxicas; o reservatório possui uma praia pública, para recreação de contato primário; e tem no entorno condomínios com casas, clubes e chácaras. Este conjunto de características deve servir de alerta às autoridades locais, pois há necessidade para se discutir o programa de monitoramento ora em curso, com indicação da redução do monitoramento para no mínimo mensal e avaliações complementares, para verificação periódica da presença de cianotoxinas.

Abstract:
Determination of status of water quality of a river or any other water sources is highly indeterminate. It is necessary to have a competent model to predict the status of water quality and to advice for type of water treatment for meeting different demands. One such model (UNIQ2007) is developed as an application software in water quality engineering. The unit operates in a fuzzy logic mode including a fuzzification engine receiving a plurality of input variables on its input and being adapted to compute membership function parameters. A processor engine connected downstream of the fuzzification unit will produce fuzzy set, based on fuzzy variable viz. DO, BOD, COD, AN, SS and pH. It has a defuzzification unit operative to translate the inference results into a discrete crisp value of WQI. The UNIQ2007 contains a first memory device connected to the fuzzification unit and containing the set of membership functions, a secondary memory device connected to the defuzzification unit and containing the set of crisp value which appear in the THEN part of the fuzzy rules and an additional memory device connected to the defuzzification unit. More advantageously, UINQ2007 is constructed with control elements having dynamic fuzzy logic properties wherein target non-linearity can be input to result in a perfect evaluation of water quality. The development of the fuzzy model with one river system is explained in this paper. Further the model has been evaluated with the data from few rivers in Malaysia, India and Thailand. This water quality assessor probe can provide better quality index or identify the status of river with 90% perfection. Presently, WQI in most of the countries is referring to physic-chemical parameters only due to great efforts needed to quantify the biological parameters. This study ensures a better method to include pathogens into WQI due to superior capabilities of fuzzy logic in dealing with non-linear, complex and uncertain systems.

Abstract:
In Dolj County there are a number of lakes that are particularly important, because they have a large quantity of water, some of them originating from hydrotechnical accumulations, and other from natural waters. In the present study, it was performed the monitoring of the water quality of the lakes in Dolj County, in the year of 2012, namely: Victoria - Geormane, Bistreţ and Caraula. The ecological conditions of the natural and artificial lakes was established based on the state of acidification, of the oxygen regime (dissolved oxygen, biochemical oxygen demand and chemical oxygen demand), the degree of eutrophication (biogenic substances, phytoplankton biomass and chlorophyll “a”) and also based on transparency. The water samples were taken from three points: tail, middle and upstream of the lake and were analyzed using high performance equipment, namely: pH-meter, spectrophotometer DR 2010, Sechi disc, BOD5 system. In terms of the degree of eutrophication, the water from the studied lakes belongs to the third category of water quality. Geormane is a natural lake which has a very good ecological status, except regarding the eutrophication, which is considerably visible. Bistret lake has a good environmental status and is visible eutrophic. Caraula lake’s water belongs to the third category of water quality, being heavily eutrophic.

Abstract:
Due to alarming increase in population and rapid industrialization, drinking water quality is being deteriorated day by day in Pakistan. This review sums up the outcomes of various research studies conducted for drinking water quality status of different areas of Pakistan by taking into account the physicochemical properties of drinking water as well as the presence of various pathogenic microorganisms. About 20% of the whole population of Pakistan has access to safe drinking water. The remaining 80% of population is forced to use unsafe drinking water due to the scarcity of safe and healthy drinking water sources. The primary source of contamination is sewerage (fecal) which is extensively discharged into drinking water system supplies. Secondary source of pollution is the disposal of toxic chemicals from industrial effluents, pesticides, and fertilizers from agriculture sources into the water bodies. Anthropogenic activities cause waterborne diseases that constitute about 80% of all diseases and are responsible for 33% of deaths. This review highlights the drinking water quality, contamination sources, sanitation situation, and effects of unsafe drinking water on humans. There is immediate need to take protective measures and treatment technologies to overcome unhygienic condition of drinking water supplies in different areas of Pakistan.

The parameters used for assessing water quality and trophic status level include: water temperature, pH, EC, TDS, DO, BOD5, nutrients, Secchi disk transparency, and chlorophyll a. The results reveal that DO is above 5 mg.l-1 in all sites, BOD5 value is within permissible level for domestic uses. Water quality considered as a hard type. High sulfate concentration is recorded during the study period. Trophic state shows that water type is classified as mesotrophic during autumn season, while it is regarded as eutrophic in other seasons. TDN/TDP ratio suggests that phosphorus is a limiting factor for algal growth. Based on IWQI, the water type is classified as excellent type for irrigation purpose.

Abstract:
Large areas of BASHEQA region haven't any source of surface water, at the same time, there are large quantities of olives trees and crops depend in its irrigating on Ground Water (GW) as a main source. So it is important to evaluate its (GW) for different uses. In this study the (GW) of 32 wells had been examined in the college of environmental science and technology laboratories to assess its Water Quality (WQ) for drinking, irrigation, and livestock purposes. Average twelve parameters (pH, Ca, Mg, Na, HCO3, SO4, Cl, NO3, EC, TDS, SAR, TH) data in the period 2008-2009 had been applied in three methods through computing Water Quality Indices (WQIS). The first method was the Weighted Average (WAV). The second one was that adopted by Ministry of Nature and Environment (MNE) of Mongolia, while the last one was the Canadian Council of Ministers of the Environment (CCME). The (WQIs) of the three methods results had been compared to assess the suitability of the best one. Although the statistical analysis indicated that there are no significant differences between both (CCME) and (WAV) methods, the (WAV) data had been used in this study as it gave more restrictive control. The analysis of (WQIs) using (WAM) method indicated that (25, 69, 88)% of (GW) are good for drinking, irrigation, and livestock purposes respectively.

Abstract:
Water is the source of life, and water quality is one of the world's significant environmental problems today; the current state of water quality problems is worrying. Traditional water quality monitoring methods usually use buoys to carry sensors or manual sampling for real-time field water quality monitoring. These methods, although the monitoring accuracy is high, are labor-intensive, expensive and time-consuming. Remote sensing technology now occupies an increasingly important position in water quality monitoring because of its low cost, wide range and fast response time. This study introduces the research status and development problems of water quality remote sensing monitoring neighborhood from water quality remote sensing principle, data source, indicators, and monitoring methods. Results show that the data source mainly contains satellite and emerging UAV data. The remote sensing indicators typically include FUI, suspended solids, CDOM, Chl-a, and TN; Traditional methods like empirical and semi-empirical methods, and developing methods like analytic method and the surging machine learning and automation methods.

Abstract:
Utilizing hygienic and sanitary water is absolutely necessary to avoid unwanted negative impacts. This research was conducted in PIR 2, Arso, Keerom Regency from August to October 2022. This research aims to determine the quality status of dug well water by using the pollution index method with 18 (eighteen) water pollution parameters namely: physical parameters (turbidity, color, TDS, temperature, taste and smell), chemical parameters (pH, iron, fluoride, hardness, manganese, nitrate, nitrite, cyanide, detergents and total pesticides) as well as biological parameters (total Coliform and Escherichia coli). The samples in this research were taken from four sample points (research stations), namely station 1 (line 1), station 2 (line 2), station 3 (line 3) and station 4 (line 4). The results showed that the water quality status of dug wells at stations 2 and 3 obtained a pollution index of 10.28 and 12.72 respectively and classified as heavily polluted, while at stations 1 and 4 the pollution index was 2.38 and 4.80 respectively and both stations were classified as lightly polluted. Water parameters that did not qualify water quality standards were turbidity, iron content and Escherichia coli. A suitable water management plan to fulfill the quality standard requirements was the well water must be filtered using zeolite media, sand, palm fiber and activated carbon (coconut shell charcoal) and added a little chlorine (chlorine) or alum to the reservoir before filtration.

Abstract:
Situ Gede is one of the artificial lakes/reservoirs in Tasikmalaya, West Java. The lake has functioned as a source of household water needs, fisheries, and tourism. According to determine the development of water management requires information on the trophic status and water quality. This study aimed to obtain information on the trophic status and water quality of Situ Gede. The research was conducted in Situ Gede, Tasikmalaya, West Java, in 2018. Measurement and analysis of water quality parameters used the SNI and APHA methods, while the measurement of trophic status used the Carlson Trophic State Index (TSI). The relationship between water quality parameters and TSI scores was analyzed using Statistica version 8. Based on the analysis, the trophic status of Situ Gede ranged from 69.06-79.04, with an average of 74.61. This value indicated that Situ Gede's trophic status was on a eutrophic level. The physical and chemical parameters that affect the trophic status of Situ Gede are TP, pH, conductivity, TDS, and temperature. The TP values, conductivity, pH, and temperature at Situ Gede were still categorized as normal. The trophic of Situ Gede can be a source of fish growth. Moreover, in general, Situ Gede waters still have sufficient water quality for fish life. Therefore, Situ Gede has the potential to capture fisheries, recreational fisheries, and aquaculture.Keywords:Trophic statusSitu GedeFisheryChlorophyll-aFish Reserve

Abstract:
The rapid growth of urbanization, industrialization and poor wastewater management practices have led to an intense water quality impediment in Lake Hawassa Watershed. This study has intended to engage the different water quality indices to categorize the suitability of the water quality of Lake Hawassa Watershed for anthropogenic uses and identify the trophic state of Lake Hawassa. Analysis of physicochemical water quality parameters at selected sites and periods was conducted throughout May 2020 to January 2021 to assess the present status of the Lake Watershed. In total, 19 monitoring sites and 21 physicochemical parameters were selected and analyzed in a laboratory. The Canadian council of ministries of the environment (CCME WQI) and weighted arithmetic (WA WQI) water quality indices have been used to cluster the water quality of Lake Hawassa Watershed and the Carlson trophic state index (TSI) has been employed to identify the trophic state of Lake Hawassa. The water quality is generally categorized as unsuitable for drinking, aquatic life and recreational purposes and it is excellent to unsuitable for irrigation depending on the sampling location and the applied indices. Specifically, in WA WQI, rivers were excellent for agricultural uses and Lake Hawassa was good for agricultural uses. However, the CCME WQI findings showed rivers were good for irrigation but lake Hawassa was marginal for agricultural use. Point sources were impaired for all envisioned purposes. The overall category of Lake Hawassa falls under a eutrophic state since the average TSI was 65.4 and the lake is phosphorous-deficient, having TN:TP of 31.1. The monitored point sources indicate that the city of Hawassa and its numerous industrial discharges are key polluters, requiring a fast and consequent set-up of an efficient wastewater infrastructure, accompanied by a rigorous monitoring of large point sources (e.g., industry, hospitals and hotels). In spite of the various efforts, the recovery of Lake Hawassa may take a long time as it is hydrologically closed. Therefore, to ensure safe drinking water supply, a central supply system according to World Health organization (WHO) standards also for the fringe inhabitants still using lake water is imperative. Introducing riparian buffer zones of vegetation and grasses can support the direct pollution alleviation measures and is helpful to reduce the dispersed pollution coming from the population using latrines. Additionally, integrating aeration systems like pumping atmospheric air into the bottom of the lake using solar energy panels or diffusers are effective mitigation measures that will improve the water quality of the lake. In parallel, the implementation and efficiency control of measures requires coordinated environmental monitoring with dedicated development targets.

Abstract:
The soil and thermal resources of the Odessa region allow growing a variety of agricultural crops with a yield much higher than currently obtained. But this is possible only when using irrigation. The southwestern part of the region has such a powerful source of water as the Danube River, from which irrigation is carried out and the lakes Cahul, Yalpug, Katlabukh, China and a number of reservoirs are filled. For a number of reasons, after 2000 the actual amount of irrigated land has decreased significantly. Along with this, the quality of water in reservoirs changes, and sometimes they disappear from the map. At the state level, various programs are being adopted to restore irrigation in the southern regions of Ukraine without understanding the presence and hydrochemical composition of the waters of reservoirs. To do this, it is necessary to conduct a detailed analysis of the presence of water bodies and assess their chemical composition. This work is devoted to one of the sources of water supply for the national economy, namely Lake Katlabukh. Lake Katlabukh is used as the main source of irrigation for three state systems - Suvorivskaya, Izmailskaya and Kislytskaya (formerly Kirovskaya) irrigation systems (IS) and small irrigation areas (SIA) on an area of 16.671 hectares. In addition, the Loschinivske, Kaminske, Banivske and Muravlivske reservoirs were additionally filled with lake waters to irrigate 22063 hectares within the limits of the Loschinivske, Tashbunarske, Muravlivske and Banivske IS and the SIA adjacent to them. The aim of the work is to analyze the hydrochemical state and assess the quality of water according to agronomic criteria over a thirty-year period of one of the lakes, the waters of which have been and continue to be used for irrigation. To solve this problem, materials of hydrochemical observations were collected and processed. The main indicators of anionic and cationic composition, mineralization index and pH are summarized and averaged for every five years from 1991 to 2020. Separately, data for 2021 is given. To assess the quality of water according to agronomic criteria, all indicators were calculated according to the latest methodology. The main reasons for the deterioration of water quality have been identified.

Abstract:
The study investigated the water supply sources in Old Umuahia semi-urban district in Abia State, Nigeria. Emphasis was on the quality and quantity of available water sources. Some socio-economic considerations such as family sizes, proximity of source, quality and quantity of water actually used per day as compared with quantity required per day were all evaluated. Water supply shortfall was hence evaluated and quantified. Different sources of water in use were evaluated. They include motorized boreholes, Springs, Streams, commercial water vendors and harvested rainwater. The study showed that the majority of residents had bread winners who were civil servants (48%) with an average family size of 5-8 people. Most people practice conjunctive water use of water combining more than one source with comparative advantages. 89% of the people depend on water boreholes for their drinking water supplies. Available hydrogeological data from the area were reviewed. The area was found to be underlain by a prolific aquifer capable of sustainably supplying the area. Water samples were collected from the different water sources and analysed for concentration of key physico-chemical parameters such as pH, Dissolve d Oxygen, conductivity, turbidity, totaldissolved solids, total hardness, chloride, salinity, total alkalinity, copper, iron, manganese, sulphate, chromium, colour and zinc. The results were compared with World Health Organisation (WHO) standards for domestic water supply. From the results, water in the area was found to be acidic with pH values ranging from 4.9 to 5.15 (mean value, 5.02). All the other physico-chemical parameters showed values that plot within the limit of acceptability of WHO standards except for two boreholes sources, two streams sources and samples from the commercial water vendors whose water samples indicated serious bacteriological contamination. Supplies from groundwater sources is of highest quality. Since the area is underlain by aquifers with excellent water yielding properties, the studyrecommended the development of water supply in the area mainly from groundwater sources. This will require additional hydrogeological studies to determine the number, location and depths of new boreholes to serve the domestic water demands of the inhabitants of the area. Existing four boreholes are grossly inadequate to meet and sustain the domestic water needs of about 8000 people who presently inhabit the area. Similarly, people should be discouraged from using the water from commercial water vendors for domestic purposes. This will drastically reducethe incidence of water-borne diseases in the area
