The study assessed the effect of waste dumpsites on groundwater quality of upper aquifers in Port Harcourt. Water samples were retrieved from hand-dug wells from a dumpsite and a control site and analyzed for physico-chemical parameters and heavy metal content. Results show that electrical conductivity of the dumpsite water samples was 42.06μS/cm while the control site water samples recorded 31.27μS/cm. Turbidity of the water samples ranged from 0.62NTU-0.65NTU. Total Dissolved Solids of the dumpsite water sample was 26.8mg/l while the TDS of the control site water sample was 33.70mg/l. The pH of water samples from both sites ranged from 5.46 -7.34. The pH of water samples from the dumpsite was slightly acidic (5.46). The average temperature of the water samples was approximately 28oC. Phosphate concentration of water samples ranged from 0.32 mg/l-0.54 mg/l while chloride levels ranged from 10.60mg/l-17.12 mg/l. All physico-chemical parameters and heavy metal content of the water samples all fell within the WHO and NSDWQ stipulated standards except for the lead concentration of the water sample retrieved from the dumpsite. The study also revealed that waste dumpsites did not alter the concentration of the measured physico-chemical properties and heavy metal concentration of water samples. However, the study recommended that periodic assessments of groundwater quality of waste dumpsites should be undertaken

Groundwater is generally used for various purposes, particularly domestic and industrial purposes in all over the world. Fresh water from groundwater sources is high in the recent years and the groundwater is polluted high because of rapid population and industrial growth. It is very difficult to restore the contaminated groundwater by various pollutants.  Hence, it is important to analyse physico-chemical parameters of groundwater for its need for various sectors. Therefore, the present study was under taken to define the quality of groundwater with the help of WQI. The ground water samples were collected from 20 different places around Ambattur Industrial Estate in Chennai city. The groundwater quality assessment showed that the water quality of bore wells around Ambattur Industrial Estate is poor for drinking purpose as per WQI for BIS acceptable limit.  WQI observed from those selected 20 groundwater bore wells are ranging from 63.30 to 219.63.   The analysis reveals that the groundwater from the Ambattur Industrial Estate needs pre-treatment before it is being used for various purposes.

Plankton Communities

Composition of plankton communities in two ponds at African Regional Agriculture Centre (ARAC) Aluu, Port Harcourt was undertaken between May and June 2004, to assess the composition, relative abundance and distribution of plankton. The diversity of plankton was poor. Twenty-eight taxa representing four (4) families were recorded for phytoplankton while seventeen taxa representing four families were identified for zooplankton. Chlorophyta and Cladocera were the most dominant classes in phytoplankton and zooplankton in terms of abundance, constitute 13.0% and 17.1% respectively. The water quality of the ponds is evident by high temperature (28.80C), depth (57.5cm), transparency (42), dissolved oxygen (4.9mg/l) and low BOD of (1.4mg/l). The lower density of organisms could be partly attributed due to heavy rainfall which destabilize the surface water and substrate. Hence, extensive studies of the ponds where aquatic organisms are kept should be carried out to maintain proper utilization of ponds.KEYWORDS: Plankton, composition, communities richness, abundance.

Water samples were collected from three points of Louhajong river (Dighulia, Kagmari Bridge and Oloa) to see the seasonal variation in physico-chemical parameters. The results revealed that some of the parameters such as TDS, alkalinity and acidity have exceeded the standard level in dry season in all of the points, which are unsuitable for different purposes including fish culture. During dry and wet seasons the highest concentrations of BOD was recorded as 2.0 and 0.8 ppm at Kagmari Bridge (point-2) respectively. DO ranged from 1.4 to 3.1 and 2.4 to 3.8 ppm during dry and wet seasons. Maximum and minimum EC was recorded as 890 and 130 ?s/cm at Dighulia (point-1) during dry and wet seasons. The results suggest that at wet season Louhajong river may be suitable for fish culture and other purposes.Bangladesh J. Sci. Res. 28(1): 9-16, June-2015

In a bid to ascertain the quality of water for human consumption in Kashere Metropolis, essential physico-chemical parameters were evaluated on samples of drinking water obtained from boreholes, pond and wells located at densely populated areas, labelled as: Kashere cattle market Pond, KP; Kashere cottage Hospital Borehole, HB; Kashere Market Borehole, MB; Federal University, Kashere (FUK) campus Borehole, CB; Kashere cottage Hospital Well, HW; Kashere Market Well, MW and FUK campus Well, CW. Standard procedure for the determination of chemical and physical characteristics of the water samples were used. The results of the investigated parameters in the samples were as follows: ρH 6.61‒7.96, Turbidity 0.0‒2568 FTU, Electrical Conductivity 60.5‒1151 Mhocm-1, Total Dissolved Solids (TDS) 25.9‒518.0 mgL-1, Ca 0.0033‒0.5446 ppm, Mg 0.0793‒1.2215 ppm, Cd 0.0010‒0.0030 ppm, Zn 0.0024‒0.l054 ppm, Pb 0.0002‒0.0026 ppm and Fe 0.0044‒0.5649 ppm. Except for the concentration of Fe (in CB; 0.5649 ppm), all the analyzed minor and major cations in the water samples were in very low concentration and below the permissible limits of WHO standard guidelines values for drinking water.  It is recommended that, water from the pond should be properly treated before consumption due to its high turbidity.  Also periodic assessment of the quality of drinking water from these water sources should be conducted, to ascertain that they are not contaminated by either or both organic and inorganic pollutants.

The objective of this work is to evaluate the physico-chemical quality of the groundwater of the Merdja plain and to determine the sources of mineralization. This quality is influenced by several environmental and anthropogenic factors such as geological context, climate, precipitation and interaction between groundwater and aquifers and human activities.  A Principal Component Analysis (PCA) on samples taken from several wells spread over the entire Tebessa plain (Merdja) allowed us to detect two axes that explain 73.4% of the information. The first axis describes the variables related to mineralisation and the second one describes those related to agricultural activity. Multidimensional Positioning (MDS) confirmed the interaction of physico-chemical parameters between them and their influence on groundwater quality by highlighting three groups of wells according to their physico-chemical characteristics, particularly those containing high concentrations of nitrates. This contamination is mainly the result of spreading the fertilisers and wastes that are dumped into the plain without treatment. Salinization is the result of long-term interactions between groundwater and geological formations.

Considering the well-documented impacts of land-use change on water resources and the rapid land-use conversions occurring throughout Africa, in this study, we conducted a spatiotemporal analysis of surface water quality and its relation with the land use and land cover (LULC) pattern in Mokopane, Limpopo province of South Africa. Various physico-chemical parameters were analyzed for surface water samples collected from five sampling locations from 2016 to 2020. Time-series analysis of key surface water quality parameters was performed to identify the essential hydrological processes governing water quality. The analyzed water quality data were also used to calculate the heavy metal pollution index (HPI), heavy metal evaluation index (HEI) and weighted water quality index (WQI). Also, the spatial trend of water quality is compared with LULC changes from 2015 to 2020. Results revealed that the concentration of most of the physico-chemical parameters in the water samples was beyond the World Health Organization (WHO) adopted permissible limit, except for a few parameters in some locations. Based on the calculated values of HPI and HEI, water quality samples were categorized as low to moderately polluted water bodies, whereas all water samples fell under the poor category (>100) and beyond based on the calculated WQI. Looking precisely at the water quality’s temporal trend, it is found that most of the sampling shows a deteriorating trend from 2016 to 2019. However, the year 2020 shows a slightly improving trend on water quality, which can be justified by lowering human activities during the lockdown period imposed by COVID-19. Land use has a significant relationship with surface water quality, and it was evident that built-up land had a more significant negative impact on water quality than the other land use classes. Both natural processes (rock weathering) and anthropogenic activities (wastewater discharge, industrial activities etc.) were found to be playing a vital role in water quality evolution. This study suggests that continuous assessment and monitoring of the spatial and temporal variability of water quality in Limpopo is important to control pollution and health safety in the future.

This paper intends to prepare the environmental impact of "Ganesh Idol" & "DurgaPratima" immersion on water quality of Kakerpura Lake, Mhow. For this purpose site of Kakerpura lake was selected where idols are actually immersed. Water samples were collected in morning at different intervals i.e. pre-immersion (August) immersion (September, October) Post immersion period (November). The "Ganesh Idols" & "DurgaPratima" are made up of degradable and non-degradable components and paints containing heavy metals due to that immersion activity deteriorates water quality. The physico-chemical parameters were analysed to study the environmental impact of idol immersion on Kakerpura Lake and these parameters shows the significant variation due to immersion of idols.

The quality of water from surface and ground water sources in Hong Local Government Area of Adamawa State was studied to determine their suitability or otherwise for drinking and domestic purposes. Nine (9) samples, three (3) each from streams, dug wells and boreholes were randomly collected, during the dry season, in the months of October and November, 2016. The samples were analysed, and the values compared with WHO and NAFDAC standards to ascertain their compliance. The results of the analysis revealed that the physico-chemical parameters studied and concentrations of heavy metals determined, falls within the maximum permissible limits of WHO and NAFDAC standards for drinking water. However, the water samples were predominantly alkaline (pH 6.30 ± 0.10 to 7.00 ± 0.10), (6.70 ± 0.20 to 7.30 ± 0.20), and (7.60 ±0.20 to 8.20 ± 0.10), for boreholes, dug wells and streams respectively. The heavy metals concentrations were determined using Atomic Absorption Spectrophotometric method. The suitability of water for domestic and drinking purposes indicates that water samples were within the standards prescribed for potable waters.
