Clean water is essential to our existence and problems might arise when it becomes contaminated with different pathogens, which might pose a threat to human health. Tap water is generally considered drinkable since it passes different forms of disinfection during processing. Some households have additional disinfection procedures, the most common one being the usage of charcoal filters, in order to further clean the tap water from both undesirable solvents and microorganisms. In the first independent study of this kind, we have tested tap water for bacteria from five different locations in Sarajevo, and we have tested the efficiency of charcoal filter in trapping of bacteria. According to regulations in Bosnia and Herzegovina, there should be 1 colony forming unit (CFU) per 50ul of water sample, which was satisfied in only one location from Sarajevo, while one had significantly higher levels (6.7, p val. 0.0148). Overall, the charcoal filter has decreased the number of bacteria in the water, with the exception of one sample.

Behavioural activities in relation to toxicological aspects involve behavioural changes of aquatic organisms under the exposure of a contaminant. The present study aims to know behavioural activities of midge larvae Chironomus sp. at the in-situ acute exposure of different chemicals containing wastewater viz. lead-acid battery industrial effluent, mixed industrial effluent and fresh tap water (chlorinated) as drinking water in comparison to control (dechlorinated) water sample (aged tap water). The Chironomus larvae were kept in three different experimental chambers (perforated wall test vessels) with the exposure of different water samples. These samples were made with no dilution, 50 % dilution, 2.5 % dilution and control water sample. The behavioral activities for larvae of Chironomus sp. were measured at 0h, 2h, 24h and 48 h in in-situ condition. The behavioral activities viz. crawling, looping, ventilation, paralyses and subsequently death of the larvae were recorded in the field condition. A significant differences (P < 0.05, P < 0.01 and P< 0.001) were observed with increasing time of exposure while in few cases the data were increased without significance level. It was recorded that after exhibiting behavioural activities viz. crawling, looping, ventilation and paralyses finally all species were died 100 % of the population in lead acid battery effluent following both 24h and 48hr exposure. In addition, death of larvae were 70 % in mixed industrial effluent and 50 % in fresh tap water (chlorinated) after 48h exposure as compared to control sample water. In conclusion, the present results indicate that the larvae of Chironomous sp. are suitable indicators in the evaluation of the effluent quality in the studied stream, potential to know by behavioural toxicological study for heavy metals and organic pollution. Although it is a preliminary observation by assessing behavioural toxicology but future study in relation to biochemical and genetic damage of Chironomous larvae with the exposure of toxic water samples will provide bigger view.

Abstract: The Effectiveness of Rice Husk Ash Filter to Reduce Turbidity of Martapura River Water. Martapura River water is used by people living on riverbanks for cooking, washing, bathing, and others. The main problem of Martapura river water is the turbidity which is relatively high so it needs to be processed first before use. The preliminary test conducted on August 15, 2016 shows the value of turbidity of Martapura river water at 38.9 NTU. This research was an experimental research with the one group pretest and posttest design which aimed to determine the effectiveness of the filter to reduce the turbidity of Martapura river water. The medium used was rice husk ash with variation of thickness were 13 cm, 26 cm, and 39 cm. The effectiveness of filtration was determined by comparing the turbidity of water filtered with standards. The turbidity of Martapura river water before filtered was 35.7 NTU. After filtered by 13 cm, 26 cm and 39 cm filter, the turbidity of water decreased consecutive to 2.97 NTU, 1.17 NTU, and 0.95 NTU, with decreasing percentages respectively of 91.7%, 96.7% and 97.3%. All filtered water showed turbidity fulfilled both the standar of clean water and drinking water so that rice husk ash filter was effective decreased turbidity of Martapura river water. Filtered water is recommended to be cooked first to boil when used for drinking water because the number of bacteria of Coli has not been studied. Further research needs to be conducted by adding other parameters according to water quality standard

Remediation of sites contaminated with radioactive material such as Cs is important because of the risk posed to human health. Here, we report the effectiveness of water containing air bubbles with a diameter around 100 nm (nanobubbled water, NB water) for the removal of radioactive Cs. Laboratory experiments confirmed that NB water is more effective than purified water and as effective as water with neutral detergent in the removal of Cs-137 from gravel. Moreover, NB water retains its effectiveness even after storage for 7 d. Finally, NB water produced onsite from tap water was found to be effective for removal of radioactive Cs from gravel conglomerate in Fukushima, Japan.

Babat Drinking Water Treatment Plant (IPAM Babat) is one of the clean water facilities for Lamongan community. The process of clean water requires an appropriate processing. This process requires chemicals and energy that it will adverse effects to the environment. Life Cycle Assessment (LCA) is one of the environmental effects analyze methods for clean water process. The four phases of LCA are Goal And Scope Definition, Life Cycle Inventory, Life Cycle Impact Assessment, and Interpretation. The environmental impacts of the LCA method of processing are divided into three broad categories of impacts, namely the categories of human health, ecosystem quality, and resources. The result of LCA analyzed shows that electrical energy utilization product an environment impact significantly. This impact has consequences on the resource category (fossil fuels) and human health (climate change) due to CO2 combustion. The largest electric consumption is used for tools of pumping water due to the distant length intake and IPAM. The solution for reduced the electric consumption is using the equipment efficiency and water flow system by the power of gravity.

Abstract The aim of this study was to assess the risk of human exposure to lead (Pb), cadmium (Cd), and mercury (Hg) through agricultural soil by considering both uncertainty and variability in key exposure parameters. For this reason we collected soil samples from 29 locations in the Tuzla Canton (Bosnia and Herzegovina) and measured their metal levels with inductively coupled plasma atomic emission or absorption spectrometry (ICP-AES and ICP-AAS, respectively). The levels of Pb ranged from 13.33 to 1692.33 mg/kg, of Cd from 0.05 to 3.67 mg/kg, and of Hg from 0.02 to 2.73 mg/kg. To estimate cancer and non-cancer risks we used deterministic and semi-probabilistic methods. Lead was found to involve higher health risk than the other two heavy metals. Its hazard index (HI) decreased between population groups (children>women>men) and exposure routes (ingestion>skin contact>inhalation). Our Monte Carlo simulations indicated that Pb HIs for both adult populations had a 0.6 % probability to exceed the threshold value of 1, while in children this probability was 14.2 %. Cd and Hg showed no probability to exceed the threshold in any scenario. Our simulation results raise concern about possible adverse health effects of heavy metals from soil, especially in children. It is very important to continue monitoring environmental pollution and assess human health risk, not only with respect to soil, but also with other important environmental compartments, such as air and water.
