Abstract This study investigated groundwater quality collected from two industrial and residential locations in each of Lagos metropolis. Prescribed standard procedures of American Public Health Association were used to measure physico-chemical parameters of each of the groundwater samples which include pH, EC, DO, TDS, BOD, COD, anions (Cl−, NO3−, SO42−, PO43−) and heavy metals (Cu, Zn, Pb, Mn, Fe, Co, Cd and Cr). From laboratory analysis, measured physico-chemical parameters were within the permissible ranges specified by the WHO and NSDWQ except pH, TDS, EC, Pb, Mn and Fe for groundwater samples from industrial locations and pH, Pb, Mn and Fe for residential locations. Higher concentrations of TDS and EC reported for groundwater samples from industrial locations were attributed to heavy discharge of effluents from industrial treatment plants as well as dissolution of ionic heavy metals from industrial activities of heavy machines. Statistical Pearson’s correlation revealed physico-chemical parameters of water quality to be moderately and strongly correlated with one another at either p  < 0.05 or < 0.01.

The ongoing degradation of the water quality of central Maharashtra’s basaltic aquifer is of great concern for different authorities and agencies involved in the water sector in the Maharashtra, India. The Kham river, which is one of the major tributaries of the Godavari river, receives all domestic and industrial waste water from the Aurangabad city. The river, with no natural flow in the dry season, is extensively used for irrigation. In order to evaluate the quality of river and groundwater in the study area, eight river water and forty groundwater samples along right and left bank of the Kham river were collected and analyzed for various parameters. Physical and chemical parameters of the river and groundwater such as pH, TDS, EC, SO4, NO3 and heavy metals like Pb, Cr, Cd, Zn, and Cu were determined. The results show that the river and groundwater of the area is generally unfit for domestic uses. Most of the physico-chemical parameters and heavy metals in the river and groundwater samples have higher value than the World Health Organization (WHO, 2006) and Bureau of Indian Standards (BIS, 2003) guidelines.

Baseline Information

Water is vital for life sustenance hence adequate, safe and accessible supply must be made available to all. The remote village of Tankpaful located in the town of Pategi has recently witnessed the installation of new boreholes to harness groundwater as an improved source of drinking water. However, there is no known information about the quality of these sources. Hence, this paper aims to investigate the quality of groundwater samples from these boreholes in terms of their physico-chemical, heavy metals and biological parameters and also provide baseline information about the nature of the underground aquifer in this community. Groundwater samples (n=20) were obtained from randomly selected boreholes in the study area and examined for their physicochemical, heavy metal and biological parameters following standard procedures recommended by the American Public Health Association and compared to guideline values. Pearson’s correlation test was done to examine the relationship between measured parameters. With the exception of pH (5.58) and total hardness (296.99mg/L), all physico-chemical parameters were within guideline values specified by the WHO and SON. For heavy metals, mean values for Iron (0.32mg/L), Chromium (0.22mg/L) and Nickel (0.4mg/L) were found to exceed the given standard limits as well. The findings revealed that boreholes were mainly acidic which could be of natural origin such as mineral dissolution. Based on correlation analysis, the major mineral groups contributing to total hardness is the K-Cl group (1.00). We recommend that regular monitoring should be done to ensure guideline values are not breached while residents should be educated on the need to maintain these water sources to prevent deterioration.

The aim of the study was to establish changes in the physico-chemical and agrochemical characteristics of gray forest large-clay loamy soil, depending on the contamination of ecotopes by heavy metals. Methods. Field, laboratory, mathematical and statistical. Results. The results of the study of the soil of areas with an over-dimensioned content of heavy metals and the transformation of agrochemical characteristics of gray forest soil in the cultivation of corn for grain. It was established that under conditions of systematic application of mineral fertilizers in agrocenoses, an increase in the lead concentration to 100 mg/kg, cadmium to 2,0, zinc to 50 mg/kg in gray forest soil did not result in a decrease in the amount available forms of nitrogen, phosphorus, potassium by plants, compared with the natural background. Concentration of lead in the amount of 1000 mg/kg, cadmium – 20, zinc – 500 mg/kg marked an increase in exchange and hydrolytic acidity and loss of humus.

The use of sewage sludge in agriculture decreases the pressure on landfills. In Romania, massive investments have been made in wastewater treatment stations, which have resulted in the accumulation of important quantities of sewage sludge. The presence of these sewage sludges coincides with large areas of degraded agricultural land. The aim of the present article is to identify the best technological combinations meant to solve these problems simultaneously. Adapting the quality and parameters of the sludge to the specificity of the land solves the possible compatibility problems, thus reducing the impact on the environment. The physico-chemical characteristics of the fermented sludge were monitored and optimal solutions for their treatment were suggested so as to allow that the sludge could be used in agriculture according to the characteristics of the soils. The content of heavy metals in the sewage sludge was closely monitored because the use of sewage sludge as a fertilizer does not allow for any increases in the concentrations of these in soils. The article identifies those agricultural areas which are suitable for the use of sludge, as well as ways of correcting some parameters (e.g., pH), which allow the improvement of soil quality and obtained higher agricultural production.

Mass Transport Process

The operational variables of electrokinetic remediation have not been cleared yet, because this method is relatively new and is an innovative technique in the aquifer remediation. In order to investigate the operational variables of the electrokinetic remediation, a mathematical model has been constructed based on the physico chemical mass transport process of heavy metals in pore water of contaminated aquifer. The transport of the heavy metals is driven not only by the hydraulic flow due to the injection of the purge water but also by the electromigration due to the application of the electric potential gradient. The electric potential between anode and cathode is the important operational variable for the electrokinetic remediation. From the numerical simulations with use of this model it is confirmed that the remediation starts from the up stream anode and gradually the heavy metal is transported to the down stream cathode and drawn out through the purge water.

The present study was conducted in the proximity of a contaminated site from Cluj-Napoca city (Cluj County, Romania), where metal processing activities have been carried out for decades. Metal content and physico-chemical parameters were analyzed in soil, water and sediment samples, while organic matter (OM) and total organic carbon (TOC) was additionally analyzed for the soil samples. The sources of heavy metals were evaluated based on multivariate statistical analysis, while the soil and sediment contamination degree was assessed based on specific pollution indices. The calculated indices indicated a significant pollution with Cd and Pb, which may represent a risk if the area would become a residential area.

Developing countries like Nigeria are faced with increased in generation of domestic, industrial and agricultural wastes, with a large percentage moving. This study evaluates the physico-chemical and some heavy metals concentration in three common species of fish from Tungan Kawo reservoir Kontagora, Nigeria; using standard methods between (July 2018 – February 2019); at four different sampling stations of human activities on the water. Five heavy metals were evaluated (Lead, Copper, Manganese, Iron and Chromium) in the fish samples. Phosphate (0.4 – 2.5) mg/L, Nitrate (3.2 – 7.5) mg/L, Temperature (27 – 32.4) 0C, Dissolved Oxygen (2.4 – 5.2 mg/L), Conductivity (81 – 125 µS/cm), Biochemical Oxygen Demand (1.9 – 4.4 mg/L), Alkalinity (mg/L) and Total Dissolved Solids (117 – 198) ppm were within the standard for drinking water and survival of fish.  However, the pH (6.3 – 9.8) was above the standard for NIS and WHO drinking water but can support aquatic life. Iron (0.64 ± 0.072 mg/kg) was the most highly concentrated in Synodontis clarias while lead (0.01 ± 0.013 mg/kg) was the lowest in Oreochromis niloticus and Coptidon zillii (formerly Tilapia zillii. This current finding indicates that the water is safe for both aquatic life and domestic purpose but not suitable for direct human consumption without being properly treated. However, there is the need for regular monitoring of the heavy metals load in this water body and the aquatic organisms because of the long term effects

The Impact

Dilúvio Stream flows through an area with a great population density in Porto Alegre, Southern Brazil. The anthropogenic influence in the surroundings impacted negatively the quality of the sediments of Dilúvio Stream and Lake Guaíba. This study evaluated the physico-chemical variability of surface sediments in a non-channeled section of Dilúvio Stream. Additionally, we compared the concentration of several heavy metals in this section with data from previous studies in the margins of Lake Guaíba near the outflow of Dilúvio Stream in order to evaluate the impact of urbanization on sediment pollution. The pH, bulk density, particle-size distribution, electrical conductivity, organic carbon, assimilable phosphorus, total nitrogen, mineralogical composition (X-ray diffractogram) and pseudo total concentration of several metals (Fe, Al, Ca, Mg, Na, K, Mn, Ba, Zn, V, As, Pb, Cu, Cr, Co, Ni, Cd, Mo, and Se) were evaluated. The results showed that the sediments in the non-channeled section of Dilúvio Stream are predominantly sandy, with heavy metal contents below the quality reference values. Quartz and feldspar predominated in all sites. The concentration of Zn, Pb, Cu, Cr, and Ni were lower than that observed in the margins of Lake Guaíba near the outflow of Dilúvio Stream, possibly due to pollution input throughout the channeled section. The Dilúvio Stream shows indications of an anthropogenic influence in the heavy metals concentration through the channeled area.
