Full textAbstract:
Water quality is closely linked to water use and to the state of economic development. Water pollution occurs when unwanted pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Water pollution affects plants and organisms living in water bodies and also to the natural biological communities. The present study is to assess the quality of river Khan at Triveni, Ujjain. Khan River flows from Indore via Sanwer it reaches Ujjain and joins Kshipra at Triveni. There are several industries in Indore, which throw their effluents in the river and it receives untreated sewage, drainage, run off from farms from the villages which are situated at the bank of this river. Though Bhangarh treatment plant has been setup at Indore to treat river Khan, only 30% of the river is being treated while rest of the water is untreated. Hence this source has been rendered unsafe for human consumption. Samples were collected from two sampling stations in the month of November. Their physicochemical analysis indicates that river water is highly polluted, BOD, COD, turbidity and TDS values are very high indicating that the water body is not fit for use

Full textAbstract:
The present investigation is centered on the Physicochemical characteristic features in water samples collected from the Puliyanthangal lake of Ranipet region which is suspected to be influenced by the intrusion of tannery effluents and domestic waste by direct and indirect means. Monthly water samples were collected at station 1 and station 2 from the Puliyanthangal lake of Ranipet area for the period of one year from May 2016 to April 2017. The range of physio-chemical parameters such as appearance (turbid/clear), colour (colourless/green), odour (none), total dissolved solids (265-1553), turbidity (0.9 - 13.17 ), electrical conductivity (76-782 Mhc), PH (6.85-7.93), dissolved oxygen (4.73-22.50 ), calcium (46.33-152), magnesium (12.10- 36.33), sodium (211-296), potassium (0.30-24.26), iron (0.02-0.49), manganese (0.01-0.29), free ammonia (0.04-1.14), nitrite (0.01-1.37) nitrate (6-41), sulphate (19.5-234) and phosphate (0.03-3.88) were recorded and discussed. Unit of the chemical parameters is represented as mg/l and physico-chemical parameters were estimated using the standard method of APHA (2005). The data was analyzed using two way ANOVA. However, escalation of physicochemical variables was noticed only in sampling station 1 and this may be due to the entry points to receive the high amount organic load from the discharge of tannery effluents and domestic wastes by direct or indirect means. It is suggested from this study that these biotopes are to be conserved from the intrusion of pollutants so that the biodiversity of the ecosystem would be sustained.

Full textAbstract:
Aquatic ecosystems respond differently to diverse anthropogenic activities in their watersheds. Phytoplankton is sensitive to their environment and is used to monitor anthropogenic impacts. A study was carried out in a South-eastern Nigerian River between December 2017 and November 2018 in 6 stations; to assess the phytoplankton community, water quality, and anthropogenic impacts. Sand mining was a major activity in the river among others. The phytoplankton was sampled with the filtration method while water was collected and analyzed using standard methods. A total of 36 phytoplankton species were recorded with Chlorophyceae being the most abundant group. The most abundant species - Melosira granulata is a pollution indicator. The water quality and phytoplankton structure showed that the water was tending towards eutrophication. This is attributed to the observed anthropogenic activities and cumulative impacts of all the activities in the watershed. The impact of sand mining activities was observed more in the downstream stations (4 – 6) while perturbation from swimming children and related activities was observed in station 1. The community structure reflected the impacts of the activities while CCA showed the major water quality parameters that influenced the phytoplankton community structure.

Full textAbstract:
The importance of water to man and aquatic organisms cannot be overemphasized. Neither aquatic animals nor plants can survive outside water. Despite this, many water bodies, especially surface water are unfit for domestic use because of water pollution as a result of several factors such as, anthropogenic activities, discharge of untreated industrial waste into the water bodies, run off of agricultural waste and chemical into the water bodies. Polluted water has a serious effect of aquatic organism as they require healthy environment for growth, development and productivity. Drinking polluted water can also lead to several diseases which can eventually lead to death. One of the key ways to determine the quality of water is through their physicochemical properties, the physicochemical properties of water is a pointer to the water quality standard. This review was conducted to determine the current status of Nigeria surface water by synthesizing current knowledge on research done on the physicochemical properties of the water in Nigeria water bodies between 2015 and 2025. Based on the finding from this work, it was discovered that most of the Nigeria surface water is polluted as most of the physicochemical parameters were above the WHO limit. By synthesizing recent knowledge this review aims to guide future research on the necessary remediation processes and decision making that help reduce the pollution levels of these water bodies.

Full textAbstract:
The present study aimed to evaluate the physicochemical parameters and the genotoxic potential of water samples collected in the upper, middle, and lower courses of the Sinos River, southern Brazil. The comet assay was performed in the peripheral blood of fishHyphessobrycon luetkeniiexposed under laboratory conditions to water samples collected in summer and winter in three sampling sites of Sinos River. Water quality analysis demonstrated values above those described in Brazilian legislation in Parobé and Sapucaia do Sul sites, located in the middle and in the lower courses of the Sinos River, respectively. The Caraá site, located in the upper river reach, presented all the physicochemical parameters in accordance with the allowed limits in both sampling periods. Comet assay in fish revealed genotoxicity in water samples collected in the middle course site in summer and in the three sites in winter when compared to control group. Thus, the physicochemical parameters indicated that the water quality of the upper course complies with the limits set by the national guidelines, and the ecotoxicological assessment, however, indicated the presence of genotoxic agents. The present study highlights the importance of combining water physicochemical analysis and bioassays to river monitoring.

Full textAbstract:
This research was carried out for comparision of status of physicochemical parameters in Qua Iboe River, Oruk Anam, Nigeria with portable water standards. Water samples were collected from five sampling locations in the study area for analysis of the physicochemical parameters in wet and dry seasons. Physicochemical parameters were determined using standard methods. Data generated were subjected to statistical analysis with Statistical Package for Social Science. The levels of some of the parameters were higher in dry season than wet season. Higher levels of some of the parameters were obtained in downstream than upstream and was ascribed to variation in levels of anthropogenic activities across the sampling locations. By extension, this indicated a likelihood of future escalation in levels of the physicochemical parameters in the river beyond permissiable limits given by World Health Organisation and other regulatory bodies in areas of higher levels of anthropogenic activities if the trend is not curbed. Comparatively, the levels of all the physicochemical parameters in the river water in both seasons were all within permissible limits for portable water standards set by World Health Organisation among other regulatory bodies. This implies that the river water quality supports life of aquatic organisms and also suitable for some domestic uses. Principal component analysis of some of the physicochemical parameters revealed positive correlation coefficients (loadings) with one another. Hence for sustainability of the river water quality by government, regulation of anthropogenic activities in the study area is strongly advocated.

Objectives: The study was undertaken to evaluate the influences of some physicochemical param¬eters and viable bacterial counts in cultured ponds (water and sediment) on the viable counts of the Pangasius catfish (Pangasianodon hypophthalmus) (gill and intestine) on a seasonal scale. Materials and Methods: Physicochemical parameters, viz., ambient temperature, water tem¬perature, water transparency, pH of the pond waters, and viable bacterial counts of pond water, sediment, fish gills, and intestines, were monitored during four different seasons. The responses of viable counts of bacteria to the seasonal changes of physicochemical parameters were also assessed using redundancy analysis (RDA) and a heatmap coupled with the clustering analysis. Results: Except for fluctuations in air and water temperatures, the other two physicochemical parameters were almost stable throughout the study periods. The gills and water counts were rel¬atively lower than those of the intestine and sediment. Pearson’s correlation analysis established no significant correlations between the physicochemical parameters and viable bacterial counts. However, significant positive correlations were detected between the viable counts of water and sediment and between the gill and intestine. The RDA plot showed that, except in spring, the viable counts of a particular sample type were similar among the four locations. The results of permutation test showed that, individually none of the studied physicochemical parameters was significant; however, the seasons significantly affected the viable counts.

Water treatment plants are of great importance in order to provide drinking water to the population. The present work aimed to study the quality of treated water from the Beni-Haroun dam (northeastern Algeria) through the analysis of its physicochemical and bacteriological parameters in order to ensure they conform to international standards. Physicochemical and bacteriological parameters of untreated water were also analysed and then compared to the same physicochemical and bacteriological parameters obtained after applying treatment procedures in order to evaluate the efficiency of these procedures on the water quality. As a result, the physicochemical parameters of treated water Beni-Haroun dam were revealed in concordance with the established international standards. Concerning bacteriological results, despite the presence of certain microorganisms in some analysed samples, their loads remained very low and do not constitute a major health risk. Based on our analyses, treated water from Beni-Haroun Dam remains generally of good quality.

Abstract <strong>Objectives:</strong> To study the water quality of the El Santuario creek located in the El Santuario Reserve, through the macroinvertebrate community analysis and physicochemical parameters. <strong>Methods/ statistical analysis:</strong> We applied the BMWP/Col-ASPT quality index to characterize surface water quality, collecting aquatic macroinvertebrates in 7 stations of the El Santuario stream, with the measurement of physicochemical parameters between the months of March and August 2017. A constrict correlation analysis (CCA) was conducted to find the relations between macroinvertebrates families and physicochemical variables. <strong>Findings:</strong> Moderately contaminated waters of dubious quality are defined which may lead to limitations in the establishment of the macroinvertebrate community, where the last station that corresponds to the exit of water of the mine, presented the quality of strongly contaminated waters in a critical situation that is reflected with the low presence of organisms. The physicochemical variables that most influence the families of benthic macroinvertebrates are as follows: conductivity, pH, total dissolved solids, and dissolved oxygen; indicating a relationship between concentration and abundance of organisms. According to the BMWP/Col-ASPT index, the biological quality of the El Santuario creek water has improved significantly in two years without coal mining, in relation to the quality reported for 2015. <strong>Application: </strong>These results contribute to environmental decision making in the management of high mountain water resources. <strong>Keywords:</strong> Water Quality, Aquatic Macro Invertebrates, Stream, Physicochemical Parameters, Páramo.

The major aim of this study was to assess the physical and chemical composition of bottled water sold and consumed in Umuahia municipal area. Samples of brands of bottled water sold in Umuahia metropolis were analysed for their physical and chemical parameters. Values obtained for temperature was highest in brand B (30 degrees celsius) and a lower value was obtained in brand C (29 degrees Celsius). Dissolved oxygen was highest in brand C (975.50 mg/l) and lowest in brand E (128.20 mg/l). Colour value was 0.003 for brand B and lowest in brand C with a value of 0.011. Turbidity for brand D was (0.06 at 700mm), while biochemical oxygen demand for brand D was 160.20mg/l. Chemica oxygen demand (COD) was highest in brand E with a vakue of 255.30mg/l as compared to brand D which had the lowest value of 123.38mg/l. Potassium was highest in brand D (1.05mg/l) and lowest in brand B (0.60mg/l). Calcium was highest in brand A (40.10mg/l) and magnesium was highest in brand B. When comparing results to WHO standards, the samples were in conformity and fell within recommended range for safe consumption. However the relative levels of chlorine and phosphate found presuppose that most of the water brands studied had some water treatments. The results obtained from the present investigation might be useful in the future for monitoring the inflow of bottled water around Umuahia metropolis.

The new calabar river (NCR) is very important to the people of Niger delta because of the pivotal role it plays in the economic development of the place with numerous companies within the vicinity of the river. The quality of water of the river felt threaten with this development. Therefore, some physicochemical parameters of the river were investigated to determine the pollution status of the river with particular reference to physicochemical parameters. Water samples were collected from the river and subjected to standard method of analysis as provided by APHA. The results of the analysis showed the following mean concentrations of the physicochemical parameters: pH (7.46), conductivity (3847.41µS/cm), TDS (417mg/l), turbidity (4.79NTU), salinity (2560.73mg/l), DO (5.8), SO<sub>4</sub><sup>2-</sup> (22.48mg/l), NO<sub>3</sub><sup>-</sup> (20.39mg/l), PO<sub>4</sub><sup>2-</sup> (0.83mg/l), Cl<sup>-</sup> (1557.66mg/l) and total harness (40.29mg/l). Of the twelve physicochemical parameters investigated, only pH, PO<sub>4</sub><sup>2-</sup>, and total hardness were within the limits set by WHO. The investigation revealed that the NCR is polluted with regard to the physicochemical parameters. It is our view that the operating companies within the vicinity of the river to ensure that their wastes are properly treated before discharged and government should see as a matter of necessity that proper environmental audit is carried out on the river.

Water-quality monitoring is one of the main instruments for water-resource management. This work therefore evaluated the water quality of the contribution basin of the Sinnott water treatment plant as well as the relationship between physicochemical water parameters, and analyzed the seasonal variation of water quality parameters as a function of rainfall. The study area encompassed the contribution basin of the Sinnott water treatment plant, formed mainly by the drainage areas of the Pelotas stream and its tributary, the Quilombo Stream, located in the city of Pelotas - Rio Grande do Sul, Brazil. A set of 118,368 data points for each stream was analyzed between 2007 and 2012. The following water quality parameters were evaluated: turbidity, temperature, color, pH, hardness, dissolved oxygen, organic matter, and alkalinity. Results showed that dissolved oxygen and water pH values conformed with Brazilian legislation in the 6 years evaluated. However, water color was the parameter that remained the greatest number of days above the set limits, mainly in the Pelotas Stream. Result indicates the need for conservation actions in the catchment, especially considering the importance of color for the assessment of water quality for public supply, in terms of both treatment costs and of public health. Highest values for water color, turbidity, and organic matter coincided with the occurrence of the highest rainfall values. Agricultural activities may potentiate sedimentation in the contribution basin of the Sinnott water treatment plant.

Seven lakes of San Pablo, Laguna were formed by a unique process called a phreatic explosion caused by steam derived groundwater. This is a one-day study done during February 7, 2017 between 8:00 am and 3:00 pm by conducting water sample in the middle of four lakes to compare the physicochemical parameters of the water and determine the presence of phytoplankton and zooplankton in each lake. It was found out that the water parameters of each lake were similar with differences and the phytoplanktons Synedra sp. and Pediastrum sp. were present and the most dominant in each lake. The similarities of the lake may be attributed to the similar environments of the lake, but the difference is influenced by the direct surroundings that differ in each lake.

This study was conducted at three selected stations in Maksutlu Dam Lake (?ark??la, Sivas), covering both the dry season (August 2023) and the rainy season (May 2024). Water samples were collected from the lake, and a total of 18 physicochemical parameters were analyzed. The Eutrophication Index (EI), Organic Pollution Index (OPI), and Nutrient Pollution Index (NPI) values were calculated for both seasons based on the physicochemical parameters of the lake water. Additionally, a Geographic Information System (GIS) was used to show the seasonal variation in index values. Bray-Curtis and Pearson correlation analyses were applied to the physicochemical parameters of the water. As a result, it was found that both the physicochemical parameters and water quality indices of the lake exhibited seasonal variation. Phosphate pollution was detected in the lake, and it was found that the lake may be oligotrophic in terms of NO? and Mg values. Several suggestions were also made for the sustainable management of the dam lake.

The present study investigates the different Physicochemical parameters of 8 ponds water in the Jashore district to identify whether the water quality in the ponds is feasible for fish cultivation. The samples were taken from various places in Jashore municipalities for preliminary analysis of Physicochemical parameters. Different physicochemical parameters of collected samples were analyzed. The result showed that the water quality parameters of all ponds were unsuitable for farming purposes with high electrical conductivity and temperature. At the same time, their nitrate levels were far lower than what was considered acceptable. The ponds have a very high bicarbonate concentration and obtained sample’s Mg ion positively correlated with electrical conductivity (P<0.05). Additionally, bicarbonate (P<0.05) and pH (P<0.01) have a very significant connection with chloride (P<0.01). Electrical conductivity of the sample used has been demonstrated to correlate positively with magnesium ions. Bicarbonate and pH have a significant and profound link with chloride where sulfate and total soluble solids are correlated. The comparative investigation of the Physicochemical characteristics of water samples with the standard parameters was carried out periodically to develop the water source for fish cultivation in the future.

AbstractThe physicochemical properties of freshwater bodies are essential indicators of the health and water quality of aquatic ecosystems. These parameters not only reflect the overall state of the water but also provide critical insights into potential threats to biodiversity and public health. This study investigates the seasonal variations in physicochemical parameters of Kalvati Lake, located in Ambajogai City, District Beed, Maharashtra, aiming to assess the lake's ecological status. Key parameters such as pH, biochemical oxygen demand (BOD), total dissolved solids (TDS), temperature, and nutrient levels (nitrates and phosphates) were analyzed over the course of different seasons to provide a comprehensive understanding of water quality fluctuations. The findings revealed significant pollution levels in the lake, primarily due to anthropogenic activities such as agricultural runoff, domestic sewage, and religious practices that contribute to nutrient overload and organic waste. Elevated levels of nitrates and phosphates were particularly concerning, indicating a high potential for eutrophication, which can lead to algal blooms, oxygen depletion, and further degradation of aquatic life. Seasonal variations in parameters like temperature and TDS also demonstrated how changes in environmental conditions influence the water’s ability to maintain ecological balance. The study emphasizes the urgent need for effective conservation strategies to address the pollution sources, such as the implementation of proper waste management systems, reduction of agricultural runoff, and community engagement in lake protection initiatives. Additionally, policy measures at the local and regional levels are essential to curb further degradation of water quality. By promoting sustainable practices and restoring the ecological balance of Kalvati Lake, the health of this vital freshwater ecosystem can be safeguarded.

This study reports the concentrations of organic pollutants, nutrients, and some physicochemical parameters in water samples from Vlora Port. Organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAH) and BTEX (Benzene, Toluene, o-, m- and p-Xyelenes, Ethylbenzene) were analyzed organic pollutants. The levels of NO3-, NO2-, NH4-, N-total, PO4-, and P-total were determined. Temperature, PH, Conductivity, Turbidity, TDS, TSS DO, BOD and COD were physical-chemical parameters determined in the water samples. Vlora Port is located in the southern part of Albania in Vlora Bay, near Vlora City in the Adriatic Sea. Elevated activities in port areas (terrestrial and marine areas) are the main causes of water pollution. Urban pollution, agriculture, and water currents can influence marine water pollution in this area. To evaluate pollution levels at the port of Vlora, water samples (12 stations) were analyzed over a two-year period (2022 – 2023). Water samples were collected during two seasons: March and July of each year Analyses of organic compounds were performed using a gas chromatograph (Varian 450 GC) equipped with ECD and FID detectors. Nutrients were analyzed using the UV-VIS technique. Titration, automatic, semi-automatic, and gravimetric methods were used to determine the physicochemical parameters. Organic pollutants were detected in all the water samples. Nutrient concentrations and physicochemical values classified the marine water of Vlora’s port as moderately good. Levels of organic pollutants, nutrients, and physicochemical parameters in water samples from Vlora’s port were higher/comparable with those reported in previous studies of the Adriatic Sea (Albania coastline).

Reservoirs, as critical water resources, serve diverse purposes such as irrigation, fisheries, and domestic water supply. This study evaluates the physicochemical parameters of Sabke Reservoir in Katsina State, Nigeria, with focusing on understanding their ecological impact and pollution status. The research, conducted between June and November 2024, analysed parameters such as temperature, pH, turbidity, dissolved oxygen (DO), biochemical oxygen demand (BOD), total dissolved solids (TDS), and conductivity across three sampling stations (upstream, middle, and downstream). Measurements were taken following APHA standards and subjected to statistical analysis using ANOVA and the Duncan Multiple Range Test at a 95% confidence interval. Results revealed significant seasonal and spatial variations in the reservoir’s physicochemical parameters. Temperature ranged from 27.96°C to 30.00°C, with higher values observed during October. Turbidity peaked at 55.83 NTU in November, exceeding WHO permissible limits and reflecting sedimentation and runoff impacts. pH values remained neutral to slightly acidic (6.32–6.89), suitable for aquatic organisms. DO concentrations (5.09–5.63 mg/L) were stable but slightly below WHO recommendations for aquatic life. TDS values (319.3–397.3 mg/L) exceeded permissible limits, correlating strongly with conductivity (r=0.617, p<0.01), indicating increased ionic concentrations. The study underscores the influence of seasonal changes and anthropogenic activities on water quality. High turbidity and TDS levels pose potential risks to aquatic biodiversity and ecosystem functionality. These findings are consistent with studies across Nigeria and other tropical regions, emphasizing the need for integrated management strategies to mitigate pollution and sustain the ecological health of reservoirs.

Findings: Parameters like temperature (ranging between 24.36 ± 0.12 to 27.63 ± 0.66), pH (8.23 ± 0.02 to 9.55± 0.01), TDS (143.67 ± 1.52 to 174.67 ± 2.08), TSS (148.00 ± 2.00 to 201.67 ± 1.52), EC (215.67 ± 3.51 to 285.33 ± 2.51), TH (75.33 ± 1.52 to 108.00 ± 01) and Nitrate etc. showed statistically significant difference between the three seasons. However, among the sites there was no significant difference observed in the three seasons. All the parameters except pH were found to fall within the permissible limits of BIS. Heavy metals such as Arsenic and Nickel were also detected in the water samples. Novelty: The surface water quality is affected continuously by various factors. Periodic assessment of water quality is hence very important. This study provides supportive evidences for season based special management to maintain the lake health for the development of sustainable biodiversity.

Full textAbstract:
Nigeria has sufficient shallow and deep water, that if polluted can be unhealthy to human life. Obibia stream is an essential water source in Amawbia-Nibo axis of Awka, Anambra State, Nigeria especially for its drinking purposes, urban agricultural usage and domestic uses. Water quality is often altered by anthropogenic activities, leachates and run off. It is therefore necessary to determine the influence of seasonal changes and its effects on the health of populace in this locality. The aim of this study is to evaluate the influence of seasonal changes on the physicochemical parameters of Obibia stream. The statistical analysis was done using ANOVA, Post Hoc Test, Correlation analyses and Paired Test. The physicochemical parameters were within the WHO standard, and the values obtained in the wet season were non-significantly (p>0.05) higher than the values obtained from the dry season, although there was moderate correlation between some selected parameters. The physicochemical parameters were observed to be higher in the wet season than the dry season. Therefore, adequate treatment before use and periodic evaluation of its physicochemical qualities are recommended.

Full textAbstract:
The physicochemical characteristics and heavy metal levels of leachates at the Rumuodumaya dumpsites and the surface water of its adjacent river was investigated by appropriate field instrument for in situ measurement, standard procedures and AGILENT 55B spectra for the heavy metals. The results from the dumpsites and surface water of the river generally indicate that as of the time of analysis, there is no serious threat to its immediate environment except the nickel concentrations in the dumpsites and surface water of the river, respectively and whose values were beyond the recommended limit of WHO/USEPA (0.05 mg/L) for safe drinking water. The trend of the results also indicates that the dumpsites are sources of numerous soil and water pollutants capable of depleting oxygen levels in the river and this could pose several and serious health risk to humans and aquatic life. Adequate solid waste disposal technique should be adopted by the appropriate agency to forestall this threat to the Rumuodumaya environment.
