<div><p>Development of organic farming in tidal land should be wise and considers all aspects supporting the development of sustainable agriculture. The aim of this research was to quantify concentration of metals contained in tidal swamp water both at the single and double tides of various tidal typologies, including Pb, Cd, Cr, and Fe ions. The research was conducted in four villages in Barito Kuala regency (South Kalimantan) to represent tidal land types A, B, C and D, respectively. Sampling was carried out at spring and neap tides in each villages and the Barito river nearest to the villages. The water samples were collected in plastic bottles in the irrigation canals and brought to the laboratory for analysis of Pb, Cd, Cr and Fe concentrations.  The results showed that the Pb, Cd, Cr and Fe concentrations in studied area were &lt;0.002 - 0.0122 ppm, 0.0067 - 0.0122 ppm, &lt;0.002 - 0.0064 ppm and 0.0358 ppm - 9.0807 ppm for Pb, Cd, Cr and Fe, respectively. Based on he limiting factor in heavy metals of water quality for agricultural crops in land C and D type are cadmium (Cd) and iron (Fe) elements. Acidity of water on the land types C (pH 2.72 - 2.95) and D (pH 2.68 - 4.41) were lower than those in the land types A (pH 6.01 - 6.83) and B (pH 3.6 - 6.29).</p></div>

The Impact

This study aims to investigate the quality and vulnerability of surface water (Aries River catchment) in order to identify the impact of past mining activities. For this purpose, the pollution and water quality indices, Piper and Durov plots, as well vulnerability modeling maps were used. The obtained results indicate that the water samples were contaminated with As, Fe, Mn, Pb and have relatively high concentrations of SO42−, HCO3−, TDS, Ca, K, Mg and high values for the electrical conductivity. Possible sources of the high content of chemicals could be the natural processes or the inputs of the mine drainage. Generally, according to the pollution indices, which were correlated to high concentrations of heavy metals, especially with Pb, Fe and Mn, the water samples were characterized by heavy metals pollution. The water quality index classified the studied water samples into five different classes of quality, namely: unsuitable for drinking, poor, medium, good and excellent quality. Similarly, medium, high and very high vulnerability classes were observed. The Durov and Piper plots classified the waters into Mg-HCO3− and Ca-Cl− types. The past and present mining activities clearly change the water chemistry and alter the quality of the Aries River, with the water requiring specific treatments before use.

Formation Zone

The water quality of the transboundary Pyanj River in the formation zone and along the riverbed before merging with another tributary of the transboundary Amu Darya River-the Vakhsh River was studied. The water quality on the upstream river corresponds to the very soft class (> 1.5 mmol/dm3) and in the middle and the downstream to the soft class (1.5-3.0 mmol/dm3). At the upper, middle and lower reaches of the Pyanj river the concentration of alkaline earth exceeds alkali metals (Ca2+ + Mg2+> Na+ + K+) at HCO3- > SO42- + Cl- and according to the Handa classification they are characterized by temporary rigidity. To assess the criterion of applicability of the Pyanj river water for irrigation the coefficient of sodium adsorption (SAC) was calculated for water samples from the upstream (Khorog), middle (Darvaz) and the downstream (Lower Pyanj) of the Pyanj river that were equal to 0.88; 1.07; 1.71, respectively. The SAC values for all water samples (from the upper, middle and lower reaches) of the Pyanj river indicate their good qualities for irrigation of agricultural land. The concentration of heavy metals in the Pyanj river is significantly lower than the maximum permissible concentration (MPC).

Water Quality Indices

The present study was conducted to evaluate the quality of drinking water in randomly selected schools in Erbil city, Kurdistan Region, Iraq. The water quality indices such as the Heavy metal Pollution Index (HPI) and Heavy metal Evaluation Index (HEI) were applied to characterize water quality. Eighteen schools were incorporated and sampled for their water storage tanks available to students. Water samples and sediment samples from tanks floor were analyzed by Inductively Coupled Plasma Optical Emission Spectrometer for the determination of twenty-two metal elements. In drinking water samples, all detected metals did not exceed the permissible limits of the World Health Organization. The results of this study showed that the average values of HPI and HEI for As, Cd, Cr, Cu, Fe, Pb, Mn, Ni, and Zn were 54.442 and 0.221, respectively. According to data of the water quality indices, the schools drinking water quality are good and suitable for drinking in terms of heavy metals. However, sediments samples contained high concentrations of all elements including the toxic heavy metals (As, Cd, Cr, and Pb). Re-suspension of sediments into water column after refilling storage tanks can pose a serious threat to students drinking water from such vessels. It is therefore recommended that proper storage tanks are provided to the schools accompanied by continuous sanitation and hygiene practice to mitigate the corrosion of tanks to avoid health risks of toxic metal

This study was conducted to know the status of physicochemical water quality parameter and heavy metal concentration in the water of Buriganga river, adjoining to Dhaka city. Water samples were collected from five different points of Buriganga river and were analyzed to determine pH, electrical conductivity (EC), total dissolved solids (TDS), dissolved oxygen (DO), biological oxygen demand (BOD), chromium (Cr), lead (Pb), cadmium (Cd), copper (Cu) and manganese (Mn) content. Most of the measured water quality parameters and concentration of heavy metals were exceeded the standard level set by ECR and ADB. Among heavy metals concentration, level of chromium and cadmium were 4-5 times higher than the standard drinking level, these results indicate that surrounding industrial wastewater discharging from textile and tannery industries, which pollute the Buriganga river water. During the observation, at Hazaribagh station BOD level was found 32 times higher than drinking water standard level and 6 times higher than standard irrigation level, indicating Buriganga river water is extremely polluted by microorganism and is not suitable for household and irrigational use. Similarly, DO level at Buriganga river water was 5 times lower than the standard level, which indicates that Buriganga river water is extremely polluted and is unsuitable for aquatic life which are dependent on DO for their sustain. In the present study, the measured level of EC, chromium, cadmium and copper were found higher level as compare to the previous studies.J. Environ. Sci. & Natural Resources, 9(2): 97-104 2016

Abstract Background An increase in the urban population and the rising demand for food and other essentials perpetuate a rise in the amount of waste being generated daily by each household. In low-income countries, this waste is eventually thrown into open dump sites. It can cause severe impacts on human health and the surrounding environment. This study was aimed at assessing the effect of a solid waste dump site of Teppi town on surrounding soil and river water quality. Methods A total of three surface water, one leachate water samples, and four soil samples were collected and were analyzed. Six heavy metals for surface water and leachate samples and four heavy metals for soil samples were measured by flame atomic absorption spectroscopy. Additionally, physical and chemical parameters were analyzed using standard methods. The soil and water data were analyzed statistically using Origin pro version 8.0 computer software packages. Analysis of variance (ANOVA) was used to assess whether the mean values of heavy metals and physicochemical parameters in soil and water samples varied significantly between distances and location from the dump site, possibilities less than 0.05 (p< 0.05) was considered statistically significant. Results pH of soil was slightly basic (pH 8±0.1 up to 8.7±0.21. Similarly, EC was lower in 60 meters (1800±0.5μs/cm) and higher in the other sample sites (3490±0.66-4920±1.04μs/cm). The concentration of heavy metals such as cadmium (0.53±0.01-2.26±0.02 mg/kg), zinc (623.93±0.29-859.41±0.02mg/kg), lead (3.26±0.25-57.560.26mg/kg), and copper (204.06±0.06 337.11±0.01mg/kg) in the sample soils has been found to be higher than Ethiopian EPA and USEPA guideline values. Lead, cadmium, manganese, nickel, copper, and zinc in the leachate water and nickel and manganese in nearby river water, total dissolved solid, BOD5, chemical oxygen demand, and turbidity for both leachate and stream water samples were found to be higher than the Ethiopian EPA and WHO standard guideline values. Conclusions The finding suggested that solid waste open dump site adversely affects soil and water quality in the study area and probable source of human health risks via the food chain. The soil in the area requires Phytoremediation technologies. In addition, sanitary landfill is recommended.

Groundwater is an important source for a drink and irrigation in the Blinaja river basin. Understanding knowledge of irrigation water quality is critical to the management of water for long-term productivity. Historically for this study area there is no data and information regarding the quality and use of water for irrigation needs. Therefore, there was a need to assess water quality based on data analysed from eight sampling points. The purpose of this paper is to evaluate, relying on analytical results, the quality of groundwater in the Blinaja river basin for the purpose of its use for irrigation of agricultural crops. For this purpose, in the Blinaja River Basin in different months during 2015, 2016, 2018 and 2019, 28 water samples were taken to assess the quality of groundwater for irrigation. Water samples were analysed in a laboratory for some of the key quality indicators; pH, EC, hardness (TH), Ca, Mg, Na, K, HCO3, SO4, Cl, etc. and then irrigation water quality indices were calculated such as: percentage of Na (% Na), SAR (Sodium Adsorption Ratio), PI (Permeability index), KR (Kelly's ratio), etc. The overall objective of this study was to assess the quality of water to be used by the inhabitants of the area for irrigation of agricultural crops. Analytical procedures for the laboratory determinations of water quality have been given in several publications (USDA Handbook 60 by Richards, 1954; FAO Soils Bulletin 10 by Dewis and Freitas1970; APHA 2005). Doi: 10.28991/cej-2021-03091740 Full Text: PDF

Abstract Background The release of environmental pollutants such as heavy metals due to mining activities has received worldwide condemnation. Therefore, understanding the contamination of both surface and groundwater in Edege-Mbeki mining district is very important for the health and wellbeing of its people. Hence, the purpose of this study was to determine the physicochemical parameters of water samples and the level of heavy metals in Edege-Mbeki Columbite/Tantalite (COLTAN) mining site, North Central Nigeria. Results A total of 15 water samples were collected and analyzed in triplicate. The concentrations of five heavy metals (Ni, Mn, Pb, Cd, and Fe) in surface and groundwater samples were measured using atomic absorption spectrophotometer (AA-6800 Shimadzu). The physicochemical properties of the water samples were also examined. The results of the water quality assessments show that the water samples were contaminated with alarming levels of Pb, Cd and Ni. Mean concentrations were Ni (0.008 mg/L), Mn (0.087 mg/L), Pb (0.324 mg/L), Cd (0.029 mg/L), and Fe (0.839 mg/L) in Edege-Mbeki groundwater, while the surface water (mining ponds) had Ni (0.102 mg/L), Mn (0.099 mg/L), Pb (0.358 mg/L), Cd (0.025 mg/L), and Fe (6.99 mg/L). The groundwater samples in Mararaban-Edege which served as the control site had mean concentration levels of Ni (0.032 mg/L), Mn (0.096 mg/L), Pb (0.122 mg/L), Cd (0.039 mg/L), and Fe (0.608 mg/L). The range of pH was found to be from 5.6 ± 0.02 to 6.5 ± 0.12, turbidity was between 39.27 ± 0.29 and 2271 ± 0.00 NTU, and conductivity ranged from 39.27 ± 0.29 to 757.33 ± 5.69 μS/cm, TDS from 25.0 ± 2.3 to 450.67 ± 6.03 mg/L while dissolved oxygen (DO) values from 3.1 ± 0.3 to 3.5 ± 0.3 mg/L. Conclusion This study confirmed that surface and ground water samples in Edege-Mbeki and Mararaban-Edege are not fit for human consumption and other domestic use. Hence, government and community leaders must provide alternative means of water for the people of these communities.

This study investigated the water quality of some of the ex-mining lakes in Perak State of Malaysia for possible use as alternative to water supply and compared them to water quality of some of the rivers used for intake of water treatment. A total of twelve (12) water samples were collected for analyses from selected sampling sites. These samples were analyzed for physico-chemical properties, heavy metals concentrations, and organic pollutants concentrations. The analyzed results indicated that average temperature varied from 28.1 oC to 34.1 oC, pH 6.2 to 9.0, EC 55 to 400 μs/cm ,turbidity 5.6 to 74.2 NTU, DO 3.21 to 9.56 mg/l, TDS 36.8 to 268 mg/l, F- 0.017 to 0.182 mg/l, Cl- 0.483 to 3.339 mg/l, Br- 0 to 0.392 mg/l, SO42- 0.051 to 15.307 mg/l, Mg 0.833 to 1.466 mg/l, Na 0.669 to 3.668 mg/l, and Ca 2.85 to 26.77 mg/l. Heavy metals concentrations (mg/l) were: Zn 0.04 to 0.057, Pb 0.019 to 0.075, Cd not detected, Ni 0.013 to 0.105, As not detected to 0.004, and Cu not detected while COD 4 to 51 mg/l. Analyses revealed that all the water samples were turbid and containing slightly high concentration of Pb. Generally, they had common water quality problem. Further work should carry out more tests on other water quality parameters particularly on heavy metals, chemical and biological pollutants at different seasons.

The aim of this study was to determine the effect of leaching of heavy metals (Cr, As, Cd, Cu, Ni, Pb, Zn, Co, Mo) and earth-alkaline metal, barium (Ba), on the percolation and ditch water quality from the forest roads that contained ash in the road structures. Water quality was studied in the immediate vicinity below the ash layers as well as deeper in the road structure. Water quality was also determined in the drainage water in ditches that crossed the forest roads. A mixture of wood and peat based fly ash was used in the road structures. The treatments were: 1) no ash, 2) a 15 cm layer of ash/gravel mixture, 3) a 20 cm layer of ash/gravel mixture, 4) a 25 cm layer of ash, and 5) a 50 cm layer of ash. Large variation in the concentrations of Cr, As, Cu, Ni, Pb, Mo and Ba in the percolation water, even within the same treatment, caused difficulties to generalize the results. The concentrations of Cr, As, Ni, Pb, Mo and Ba in water samples were high in some treatment plot lysimeters containing ash compared to the control (no ash). On the other hand, many lysimeters had low and similar concentrations in water samples in the treatment plots containing ash compared to concentrations in the control plots. The ash in the roads did not affect the concentrations in the ditches. The leaching is uneven and seems to take place only from some parts of the ash layer. Risk for leaching is minimal if such parts are not widely spread.

This study was conducted to assess the water quality of the lower Indus Basin, Pakistan. Eighty- two water samples were collected from forty-one locations of lower Indus Basin (Kashmore to Keti-Bander) during pre and post monsoon seasons. The variation pattern in the water quality has been observed in both seasons. The samples were analysed for physical quality (temperature, pH, turbidity, dissolved oxygen, total dissolved solids, salinity and conductivity), chemical quality (chloride, total alkalinity, total hardness, sulphate, potassium, sodium, iron, zinc, lead, mercury, copper, cadmium and nitrate) and biological quality (coliform bacteria). The study reveals that the concentrations of lead, mercury, and cadmium in water samples during both seasons were slightly higher than the permissible limits, whereas, all other parameters were within WHO guidelines. The higher concentration of heavy metals must be rectified by the concerned authorities in order to protect human health.
