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.

pollution risk
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:: Surface sediment quality of potential rivers in Peru was evaluated using indicators of contamination, accumulation and ecological risk of heavy metals and As. Surface sediment samples were collected at 54 sampling sites in the Tishgo and Chia rivers during 2018. The determination of Cu, Pb, Zn and As was performed by flame atomic absorption spectrophotometry. The results revealed the decreasing order of the mean concentrations of heavy metals and As in the Chia River of Zn > Cu > As > Pb and Tishgo of Zn > Pb > As > Cu. The PLI for the Tishgo River were greater than one (PLI > 1) denoting the deterioration it has been experiencing. In the Chia River, 60% of the sampling sites indicated no appreciable contamination by these elements (PLI < 1). The Igeo values of As in both rivers showed a state of contamination, from moderately to severely contaminated. In the Tishgo River the potential ecological risk varied from low to moderate and in the Chia River from low to considerable. Finally, this study reveals the applicability of the evaluation indexes of contamination, accumulation and potential ecological risk of toxic metals so that special control measures can be adopted.

Opis:: A total of 316 soil samples in the An Giang province were collected from the industrial zone (48 samples), mining (40 samples), farming (112 samples), landfills (88 samples) and cemeteries (28 a samples) to analyze toxic elements, including Cu, Zn, Pb, Cd and As. The geoaccumulation index (Igeo), pollutant load index (PLI) and potential ecological risk index (RI) were used to assess pollution levels and ecological risks. The results showed that the concentrations of heavy metals were almost still within the allowable limits of national standards. Cd was not detected. Heavy metals were detected in the soil in the following order: As < Pb < Cu < Zn, mining < industrial < landfill < cultivation < cemetery areas. The heavy metals contributing to soil environmental variability were similarly identified in the cemetery with industry and landfill with farming. The value of Igeo shows that As has a high potential to accumulate in soil in all land uses. The ranges of PLI values presented that the soil in industrial, farming, mining and landfills areas were classified moderate, while the cemetery areas has been rated at a high level. The RI values identified very high, high, and moderate ecological risks for cemetery, industrial and farming land and landfill, mining, respectively. The combination of PLI and RI indices showed that the cemetery areas were at the highest levels of pollution and risk. The results of this study provide scientific information on pollution level and ecological risks in various land use types supporting environmental zoning and managing strategies in the An Giang province.

Opis:: The heavy metal contamination has become a serious problem in the aquatic environment, including marine sediments. This study was aimed at analyzing the content of heavy metals in marine sediments, then assessing and evaluating the level of heavy metal contamination and its ecological risks. The sediment samples were taken using a grab sampler at six sites in the coastal waters of Mimika Regency, Indonesia. The TCLP testing method was used to determine the content of heavy metals in marine sediments. The results showed that the concentrations of Pb, Cu, Cd, and Hg in marine sediments ranged from <0.25 to 0.59 ppm, <0.02 to 0.54 ppm, <0.005 to 0.03 ppm, and < 0.0007 ppm. Only the concentrations of Cu on the Meoga and Puriri sites exceeded the quality standard in the Government Regulation of the Republic of Indonesia No. 18 year 1999. The results of the assessment of heavy metal contamination and its ecological risk potential indicate that the coastal waters of Mimika Regency are included in the category of low contamination and low ecological risks. The concentration of heavy metals in this study shows that the coastal waters of Mimika Regency are not contaminated by Pb, Cu, Cd, and Hg heavy metals.

Opis:: Public crude oil fields in Wonocolo sub-district were active from 1942 until now and have inadequately operated. The aims of this research were to measure the level of total petroleum hydrocarbon (TPH) pollution and their distribution in soil and surface water at the Wonocolo public crude oil fields. Twelve composite soil samples were collected from uncontaminated and contaminated sites of old well (OW), transportation line (T), and refinery area (R) at the depths of 0–30 cm, 30–60 cm, and 60–90 cm. The composite surface water sample was obtained from two points with different distances from the river side. TPH from soil and surface water samples were extracted using soxhlet and gravimetric method. Quantification of TPH was performed using Fourier Transform Infrared (FT-IR) Spectrometer. From the results of this study, it was concluded that soils and surface water are contaminated by TPH of 119.80–107,190 µg/g and 211,025.73 µg/L, respectively. TPH is clearly located in the upper of 0–30 cm depth at OW, T, and R sites (52,328.14–107,189.63 µg/g). These concentrations exceeded the soil quality standard of TPH and classified as category A for human hazard risk. The findings from this study show that there are considerable health risks which are potentially poisonous to humans in the local area. We recommend that remediation could be conducted using biological methods to reduce TPH pollution level.

Youtefa Bay
Opis:: This study aimed to analyze the heavy metal contamination in sediments and their potential ecological risks. The sediment samples were collected using PVC pipes and grab samplers at nine study sites in Youtefa Bay, namely five sites in the mangrove ecosystem, two sites in the estuary, and two sites in the middle of the bay. The heavy metal content was analyzed using Atomic Absorption Spectrophotometry. The results of the analysis of the heavy metal content in the sediment were in the following order: Zn > Cu > Pb > Ni > Cr > Cd > As > Hg (106.077±98.857, 28.553±30.505, 19.798±11.541, 17.665±11.457, 12.103±0.124, 2.996±1.235, 0.149±0.124, and 0.082±0.047 mg kg-1, respectively). Only the Cd content has exceeded the Threshold Effect Level (TEL) at all study sites. On the other hand, the As and Cr content has not exceeded TEL at any study site. The content of Hg, Cr, Pb, Zn, and Ni has exceeded TEL only at a few study sites. The heavy metal content in estuary sites is higher than in mid-bay and mangrove sites, which can provide the information on the sources of heavy metal contaminants. There is a significant correlation for the content of Cu, As, Pb, Cd, Zn, and Ni which can indicate that the sources of these heavy metals are relatively the same (r = 0.569 to r = 0.950). The CF and Igeo values indicate that there has been contamination of several heavy metals studied. Further analysis ( ERI ) showed that the heavy metal content in the sediments poses a potentially serious ecological risk. Most of the potential ecological risks are the contribution of Cd and Hg which have high toxicity factors and this should receive special attention from local governments and stakeholders to prevent higher contamination.

Opis:: The Cisadane River, Tangerang City, is one of the most important rivers in Indonesia. This river provides raw water for Municipal Waterworks (PDAM) of the Tangerang City and Soekarno-Hatta International Airport, but the water quality tends to deteriorate due to pollution. The government has made various efforts to manage the river water quality, but no significant resolution was issued yet. The problem is becoming more complicated due to land-use changes that affect the pollutant load. Therefore, more precise, integrated, and comprehensive management is needed. This study used an approach with various methodologies according to the stages of the research, including; qualitative and quantitative analysis, GIS, statistics, risk management, and System Dynamic. The outcome of this research was the development of the policies in river water quality management, specifically land use manage-ment, separation of drainage channels from domestic sewage channels, enhancement of Wastewater Treatment Plant (WWTP) services coverage, as well as reinforcement of institutional and regulatory aspects, especially in funding commitments.
