Opis:: The purpose of this study was to assess the groundwater contamination from a sewage sludge landfill. The analysis was carried out in 2017 in accordance with the requirements of the national legislation for monitoring landfills and priority pollutants. The samples of groundwater from the landfill were taken from 25 observation wells, from depths of 45–60 m. The status and dynamics of changes in the landfill groundwater quality were estimated according to the data from the groundwater observation wells of the city observation network with regard to the chemical composition of groundwater and national standards of groundwater quality. The forecast estimates of a low level of pollutants entering groundwater through the soils characterized by low filtration properties were not justified. The concentration of heavy metals in groundwater was within the following range: Fe > Mn > Zn > Al > Cu > Ni > Pb > Cd > Hg. The excess concentration of the nitrogen-containing pollutants was observed within the range from 1.5 to 76 (on average 10 times) above the background value. The organic contamination of landfill groundwater (COD) is 2–9 times and BOD5 – 1.5–3 times higher than the average background value of groundwater observation wells in the city network. The probable cause for the pollutants entry into groundwater is associated with lithogenous and exogenous fracturing of the rocks and insufficient efficiency of the existing anti-filtration system of the landfill.

Opis:: The Mio-plio-quaternary aquifer of the Djelfa Syncline is part of a region in Algeria which is characterized by the lack of surface water resources and located in a semi-arid climate. Since alluvial aquifers, and among them our aquifer, are the most vulnerable because of thier direct exposure to the pollution caused by the infiltrated pollutants, this work focused on the assessement of groundwater pollution vulnerability, hazard and risk. Thus, several methods were used; for this purpose, such as the DRASTIC and WQI methods mapped using a GIS. The results obtained clearly show a low to moderate vulnerability. The DRASTIC model and its validation based on the correlation with WQI revealed a low correlation ($WQ_I$vs $D_I$ : 0.221). Since the vulnerability model does not match with the groundwater quality, pollution risk was assessed by combining vulnerabilty and hazard (i.e, water quality). The risk map illustrated three levels ranging from low to high risk. This map should be helpful in decision making and groundwater management through avoiding high risk areas.

Opis:: Coastal aquifers are usually vulnerable to contamination by saltwater intrusion. The degree of contamination depends on the amount of former seawater intruding the aquifer as submarine groundwater discharge (SGD). A three-dimensional numerical SEAWAT model was developed to provide insights to the responses of saltwater intrusion and amount of seawater portion of SGD, to groundwater withdrawal from four wells at different spatial locations. The results showed that saltwater wedge encroachment varies with a withdrawal rate and well location. Increasing withdrawal rates from 0.165 $m^3$/s to 0.53166 $m^3$/s resulted in a noticeable increase in wedge encroachment into the aquifer from 589 m to 1319 m, respectively, regardless of the distance from the coastline. However, higher withdrawals from the wells closer to the coastline caused the hydraulic head near the seaside to drop below the terrestrial head, causing the saltwater wedge to be pushed back toward the sea. Simulations also showed that a coastal well might act as a hydraulic barrier that prevents the brackish zone from moving further inland, which is critically important in terms of groundwater management. Seawater contributed from 5% to above 33% in SGD. Although the withdrawal rates from Well 3 were 10 to 20 times larger than the Well 2 rates, the seawater contribution associated with Well 3 was about the same. This is attributed to the horizontal vicinity of Well 2 to the seacoast boundary compared to Well 3 even though Well 3 is deeper than Well 2, demonstrating that it is the horizontal location that governs the amount of abstracted former seawater.

Opis:: The leachate coming from the landfill is a serious problem. This is because the leachate water can contaminate the wells of the residents around the landfill. This research was conducted at Jabon Landfill located in Jabon District of Sidoarjo Regency, East Java Province, Indonesia. Jabon Landfill has been operating since 2003 with a controlled landfill system that has triggered environmental risks due to the leachate output. The purpose of this study was to determine the classification of the shallow groundwater quality status based on the pollution index (PI) around Jabon Landfill at a distance of around 250 meters, 500 meters and 1,000 meters from the landfill. The pollution index was determined by analyzing the pollutant concentration consisting of these following parameters: pH, BOD, COD and Fe. The results of the analysis show that the pH parameter had a higher value than the pH at Jabon Landfill of 7.2–7.5. The pH at Jabon Landfill was 6.35. The Fe parameter shows that the value of 1.694 in the groundwater well closest to Jabon Landfill and the wells further away indicates that the Fe concentration was lower for the latter, namely 0.081 at a distance of up to 200 meters. On the basis of the Pollution Index, the highest value was 5.45 at Well 7 is located 196 m from Jabon Landfill. Meanwhile, the well furthest from Jabon Landfill at a distance of 1,000 m showed a lightly polluted status with a Pollution Index of 1.91. The further the location of the well away from Jabon Landfill, the Pollution Index value tended to decrease. This means that the pollution status generally improves. Overall, the pollution status of the 18 wells shows that 2 wells are moderately polluted, 15 wells are lightly polluted and 1 well is in good condition.

Opis:: The protection and preservation of good groundwater quality is of critical importance worldwide, nowadays. Increasing urbanization, economic development and agricultural activities, combined with limited precipitation contribute to the quantitative and qualitative degradation of groundwater resources, especially in the eastern Mediterranean region. For this purpose, a series of actions are implemented including groundwater vulnerability mapping that can depict prone to pollution aquifers which need protection and/or restoration measures. In this study, the efficiency of two well-known methodologies (COP and DRASTIC) for groundwater vulnerability and pollution risk mapping was assessed in the Sperchios river basin. The vulnerability and pollution risk maps of the two methodologies were spatially compared to each other and the observed similarities and differences were discussed and explained. The output of the study shows that in the particular geoenvironmental conditions DRASTIC method performs better than the COP, particularly in the lowland, porous media aquifer.

Opis:: The depletion of aquifer systems in arid and semiarid regions worldwide is causing acute water scarcity and quality degradation, and leading to extensive ecosystem damages. Groundwater is exposed to a variety of anthropogenic water pollution, such as raw wastewater disposal in the Draa Wadi and the use of septic tanks. In this respect, a study performed in some wells of Fezouata (South-east of Morocco) aimed at both discovering the main components of the aquatic subterranean fauna unknown up to now in this area, and the potential relationships between this fauna and the water quality The principal physico-chemical characteristics of water were measured between November 2019 to March 2021 for 15 wells, which were selected considering their position with respect to the pollution sources known in surface. The Fezouata groundwater is distinguished by its high salinity with an increasing gradient from upstream to downstream. The aquatic fauna in the 15 wells showed 12 stygofauna species. In the protected wells which are situated far from the pollution sources, the fauna is dominated by Cirolanidae, Hydrobiidae, Metacrangonctydae, Stenasellidae, and Thermosbaenacea. On the other hand, in the less protected well, close to the pollution sources, the fauna is made of epigean species, such as insect’s larva, mainly Culicidae and Chironomidae. The analysis of the water quality and the subterranean biodiversity shows that the latter decreases with increasing groundwater pollution. It seems that the impact of the acute pollution affected the stygocenose even by reducing drastically the biodiversity.

Opis:: During the current research the level of groundwater (piezometers P2,P3,P4) and surface water (reservoir B) contamination during landfill operation and after its closure were examined. 113 samples of groundwater and surface water were collected from spring 2005 until spring 2012, i.e. three years after the landfill closure. The samples were analyzed for pH, EC, PAH, TOC and six heavy metals: Cr, Hg, Zn, Pb, Cd, Cu. The heavy metal concentration in groundwater and surface water both during landfill operations and after the landfill closure remained on a similar level and did not exceed permissible levels determined by WHO. Cr was an exception, because its concentra¬tion, during landfill exploitation, reached the value of 0.028 mg/l in surface water. In all examined after the landfill was closed a decrease in the EC value was observed. With the landfill closure the TOC concentration in groundwater increased from 1.8–3.4 to 2.07–3.6 mg/l and the PAH concentration from 0.01 to 0.02 mikrog/l. It may be attributed to a slowdown of decomposition in landfill. An additional PAH source for ground and surface water are surface run-offs form road pavements, yards and parking lots. The remaining high TOC level in a surface reservoir after the landfill closure is also a result of eurotrophisation, which enriches water with organic substances. Seasonal changes in the concentration of pollutants were observed, resulting both from their dilution by atmospheric precipitation (EC, pH, Cd, Cu) and due to washing them out from neighboring areas and enriching with them the analyzed water (Cu, PAH, Hg).

Opis:: The main aim of the paper was to formulate a proposal of using the draining barriers as a method of limiting pollutants in the groundwater reservoir. Primary processes of pollutants migration and examples of functioning the draining barriers work against the spread of various pollutants in the groundwater were indicated. An untypical kind of draining barrier, i.e. wells which were designed as a hydrogeological borehole to exhaust water intended for consumption, was selected as the research object. For analytical purposes, the available archival results of the physicochemical analysis of groundwater exhausted from the wells, located in the water intake so-called “belt D” in Kraków-Nowa Huta were used. The database was analysed by specialist programs, and the dispersion migration of pollutants from the existing metallurgical waste dump “Ruszcza” in time was presented. Temporary and spatial variability of the physicochemical parameters of groundwater was done during the analysis. The analysis was performed both in the draining barriers wells and in the intake boreholes. A geostatistical analysis of the variability of pollutant spread in the groundwater medium was a vital factor in the appraisal efficiency of the draining barriers operation. It was shown that the highest contents of the researched substances were present in the wells, which are located the nearest of metallurgical waste dump “Ruszcza” and are thereby the wells co-forming draining barriers. The efficiency of draining barriers was found after a thorough analysis.

Opis:: In this work, physicochemical and bacteriological analyses of leachate collected from three different landfills in the Marrakech region in Morocco were carried out. The results showed that the leachate is highly loaded with organic matter, chemical and bacteriological elements and some heavy metals, this load depends of the nature of landfill (rural or urban) and also of its age (young or old), the values of the parameters exceed the limit values for discharge into the natural medium. Physicochemical and bacteriological analyses of groundwater from wells downstream of these landfills were also carried out; The results showed that they had medium to poor quality according to the type of landfill. This is due to the presence of organic matter, total coliforms, total phosphorus and total nitrogen in many studied wells.

Opis:: In this article, the purpose of the research was to study the ecological characteristics of groundwater and central water supply used for drinking and economic activity of the Kievka village. The hydrochemical indicators of the samples were determined with conventional methods, and performed on 16 indicators: pH, electrical conductivity, suspended solids, dry residue, chlorides, sulfates, phosphates, total hardness, sodium, ammonium nitrogen, nitrites, nitrates, chemical oxygen consumption (COD), anionic surfactants (APAS), total iron, and manganese. While assessing the hydrochemical state of drinking water in the village of Kievka, it can be noted the "Altyn-dan" kindergarten and the Kiev secondary school No. 3, exceed the MAC which is determined by certain indicators. As a result of microbiological studies of the water samples from the village of Kievka, it was revealed that the total microbial number is normal. It was determined that a different number of fungi and actinomycites were present in all samples. At the initial concentration, a large concentration of fungi was observed in all samples.

Opis:: Monitoring leachate, groundwater and surface water aiming to determinate the concentration of heavy metals (Hg, Zn, Ni, Cr⁺⁶,Cd, Pb) at the municipal solid waste landfill Štěpánovice took place in the years 2002–2010. The values of heavy metals concentration oscillated as follows: Zn (0.05 – 0.37 μg/ dm³), Cr⁺⁶ (0.01 – 3.3 μg/dm³), Hg (0.0001 – 0.001 (μg/ dm³), Ni (0.001 – 0.19 μg/ dm³, Cd (0.001 – 0.007 μg/ dm³) and Pb (0.002 – 0.176 μg/dm3). The measured data show that the concentrations of heavy metals met the limits provided by law. Under the current landfill operation mode, the results of measurements do not indicate any negative impact on the quality of surface water, groundwater or leachate water.

Opis:: The monitoring that was carried out at the landfill specialized in leachate, groundwater and surface water. There were 6 sampling sites. The observed parameters were pH, BOD₅, COD_Cr, conductivity. Leachate reached the high values in all observed parameters. Groundwater samples were collected at two monitoring wells and the sampling site (A, B, C). Surface water was collected from two sampling sites (D, E). The pH showed slightly acid values at all sampling points. The pH of surface water was slightly acid to neutral. Both BOD₅ and COD_Cr values remained stable over the reporting period. The average conductivity value at sampling points D, E remained constant. In line with the Czech National Standard ČSN 75 7221 “Classification of Surface Water Quality” sampling point D belongs to II Water Quality Class – slightly polluted water and sampling site E to Class I water quality – unpolluted water. The authors believe that the fluctuations occurring with regard to the values of certain samples were not caused by the operation of the landfill itself, but were a result of the intense agricultural activity nearby the landfill.

Hatiya Island
Opis:: Groundwater meets the majority portion of drinking water needs, particularly in the rural area of Bangladesh. Groundwater has been continuously contaminated by potentially harmful metals as a result of natural processes as well as some anthropogenic activities, creating a variety of health impacts. The current research aimed to evaluate the naturally occurring level of metal contamination and the human health risk associated with deep groundwater in the Hatiya Island. Because of the arsenic, iron, and salinity problem in shallow groundwater, the inhabitants of the Hatiya Island use deep groundwater. During the field investigation, no shallow tubewells were observed; therefore, only deep groundwater samples were collected. The total sample size collected throughout the Hatiya island was 17. Five metals (Zn, Fe, Mg, Mn, and Cu) were analyzed using an Atomic Absorption Spectrophotometer (AAS). The concentrations of studied potential risky metals were ranked as follows: Mg > Zn > Fe >Mn> Cu. The detected values of all metals except Fe were found within the drinking water limits of WHO (2017), BIS (2012), and BDWS (1997), where only 29.41% of the Fe sample exceeded the standard drinking limits. According to the metal evaluation index (MEI) and degree of contamination (Cd), the groundwater of the study area is free from contamination but the metal pollution index (MPI) and nemerow pollution index (NI) exhibited little pollution in the mid-western part of the study area. The hazard quotient (HQ) values revealed no oral and dermal health risk for individual metals (Cu, Zn, Fe, Mn). On the other hand, the hazard index (HI) values exhibited no risk for combined metals as none of the values exceeded the safety limit value of 1. According to the HQ and HI results, the deep groundwater on Hatiya Island is non-carcinogenic and risk-free for children and adults. However, children were more susceptible to oral health risks than adults. In contrast, adults were more vulnerable to dermal health risks than children.

Opis:: The eventual polluting of the Ouichane region’s groundwater by heavy metals around an abandoned iron mine was investigated. To reach this aim, the research began with a questionnaire survey to assess local people’s use of and appreciation for well and spring water, followed by measurement of spatial pollution load of heavy metals: Al, Ag, Fe, Cd, As, Cr, Co, Zn, Pb and Cu for water samples collected from twelve wells and three spring drinks of water using inductively coupled plasma-atomic emission spectrometry method (ICP). Determining the overall quality of spring and well water for human use was also performed by calculating the heavy metal pollution index (HPI). As result, the survey revealed that 44.90% of the households are not connected to the drinking water network, 97.3% of them use well water, which is highly appreciated, and 88.1% of the population consider its quality to be good to excellent. Meanwhile, the ICP analysis showed that all the water samples contain heavy metals. In fact, the maximum concentrations (expressed in 10-5 g/l) recorded per element were 9.7 for (Ag), 15 for (Al), 6.9 for (As), 4.5 for (Cd), 5.6 for (Co), 31 for (Cr), 14 for (Cu), 858 for (Fe), 7 for (Pb) and 2.9*10-5 g/l for (Zn). Moreover, most of the water samples recorded heavy metal values above World Health Organization (WHO) limits, for at least one metal among the ten tested, with high concentrations of iron observed in all samples. The HPI values for the three explored sources (S1, S2 and S3) and for 8 out of 12 wells (P3, P4, P5, P6, P7, P8, P9 and P10) exceed the critical pollution value and identify non-potable water with a high potential of contamination. Consequently, the results of this study raise the question about groundwater around this abandoned mining area, especially in the long term, the use of groundwater could increase because of the succession of years of drought on Moroccan territory and hence may constitute a significant health risk for most of the inhabitants.
