Groundwater is one of the main alternatives for people to get clean water easily, because the construction is relatively easy. Therefore residents around the landfill use ground water. Final Disposal Site (TPA) is a place where waste has reached the final stage in its management. Well water around the landfill will usually be polluted by various chemicals that are harmful to the body, one of which is organic matter. Organic substances are substances that contain a lot of carbon. Examples are benzene, chloroform, detergent, and pentachlorophenol. High levels of organic matter indicate that the water has been polluted. Therefore, the determination of the level of organic matter in the samples of borehole water so that the quality can be known quality. To determine the level of organic matter in the sample of community drill well water, quantitative analysis was carried out using the permanganometric titration method. The principle of the permanganometric titration method is that organic matter can be oxidized with KMnO4 in an acidic atmosphere by heating. The remaining KMnO4 is reduced with excess oxalic acid. The excess oxalic acid is titrated again with KMnO4. Based on the results of the analysis, the levels of organic matter contained in well water samples amounted to 586.8 mg / L. So it can be concluded that the sample of community drill well water is not suitable for drinking, because it does not meet the criteria of drinking water. The criteria for drinking water according to the Minister of Health of the Republic of Indonesia No.492 / MENKES / SK / VI / 2010 are not containing more than 10 mg / L of organic matter. This is because the amount of organic matter will result in increasing the population of microorganisms and can lead to the development of dangerous pathogenic bacteria in the human body, especially for the immune system.

The community around Tempat Pembuangan Akhir (TPA) II Musi II Kelurahan Karya Jaya still relying on borehole water to fulfill their daily needs. The existence of TPA around these community environments can have a negative impact, including an indication of contamination of borehole water. One of the water pollution that is suspected to occur due to contamination of leachate from TPA is over chloride level in borehole water. The present work aimed at determining chloride level in borehole water in the area around Musi II TPA II Musi II Kelurahan Karya Jaya using Mohr argentometry titration method. The results showed chloride level in borehole water in the area around Musi II TPA II Musi II Kelurahan Karya Jaya is 301.75 mg/L. Based on PerMenKes RI No.492/MENKES/SK/VI/2010 and PerMenKes RI No.416/MENKES/ PER/IX/1990, the maximum level of chloride for drinking water is 250 mg/L, while for clean water is 600 mg/L, so that it can be concluded that borehole water in the area around Musi II TPA II Musi II Kelurahan Karya Jaya can’t be used for primary needs, for example drinking and cooking needs, but borehole water can still be used for secondary needs such as bathing and washing.

Introduction. Boron is a trace mineral that is supposed to be essential for human health. Organic plant based boron compounds are highly bioavailable for humans and can positively influence minerals such as calcium, phosphorus, magnesium and act in synergy with vitamin D, which are beneficial for osteoarticular health. Material and methods. We made an analysis of 126 bibliographic sources and mapped the Republic of Moldova to the content of boron in deep water and to the adults’ prevalence of rheumatoid arthritis and inflammatory polyarthropathy. Results. Boron is important for osteogenesis and its deficiency can lead to impaired growth and abnormal bones development. It supports bone health in postmenopausal women by reducing urinary loss of the minerals such as calcium, magnesium and phosphorus, which are essential for bone building. In countries where soil was depleted of boron and daily intake of this mineral was 1 mg or lower, the incidence of arthritis was between 20 and 70%. In Moldova, in the regions where boron concentration in deep drinking water were low (0.28 mg/L in well water and 0.51 mg/L in artesian well water) in Soroca in 2019, the prevalence with the rheumatoid arthritis and inflammatory polyarthropathy were high (51.6 per 10000 inhabitants) with one exception, UTA Gagauzia (35.1 per 10000 inhabitants), where we found a high boron concentration in deep drinking water (2.05 mg/L in well water and 2.2 mg/L in artesian well water) in 2015. Conclusions. Boron can affect bone metabolism. In regions where boron concentration in deep drinking water is low, the osteoarticular morbidity can be higher with the exception of UTA Gagauzia, where we suppose that dietary pattern can be a cause of these results. In the future we will study eating habits in this region and a clearer conclusion will be made.

Introduction. Oncological pathology has a high medical and social significance, so it is important to study the conditions of its formation. The aim of the study was to evaluate the cumulative carcinogenic risk for the population of the administrative center of the Republic of Buryatia (Ulan-Ude). Material and methods. The identification of the carcinogenic hazard caused by the entry of chemical ingredients into the ambient air was carried out in 2005-2015. The exposure assessment is based on long-term average annual concentrations of carcinogens in the air, drinking water, food. Indices of comparative carcinogenic hazard (HCR) and individual carcinogenic risk (ICR) are calculated. Results. The huge engineering enterprises are sources of several substances with carcinogenic effects (formaldehyde, chrome VI, cadmium, niсkel, epichlorohydrin, etc.).The individual carcinogenic risk for residents of Ulan-Ude is included in the range unacceptable for the general population. The main pathway for chemical agents to enter the body is inhalation (79%). The greatest contribution to the total individual carcinogenic risk on admission from the air was made by formaldehyde, chromium VI and Benz(a)pyrene. Priority carcinogens coming from drinking water and food are arsenic, cadmium, lead. Conclusion. Results of the assessment of individual carcinogenic risk in Ulan-Ude indicate an unacceptable level of the impact on the population. The assessment has a number of uncertainties, which determines the need to further improve the monitoring system for carcinogenic hazards.

Abstract: Diarrhea is still a health problem in the world which can be seen from the high rates of morbidity and mortality due to diarrhea in children worldwide. In patients with diarrhea, nutrients needed by the body are excreted along with the occurence of body dehydration. Therefore, when a child under five years has diarrhea oftenly, then his/her growth can not be optimal. This was an analytical observational study with a cross sectional approach, conducted in Tondano Watershed during November to December 2014. Subjects were 70 children under five years old. Data were collected by using questionnaires and then were analyzed with the chi-square test. The results showed that there was no correlation between sociodemographic factors (education, occupation, and ages of the mothers), sources of drinking water, and house floors with the occurence of diarhhea (P > 0.05). However, there was a correlation between excreta disposal sites and the occurence of diarrhea (P = 0.003). Conclusion: There was a correlation between excreta disposal site with diarrhea in Tondano watershed and there was no correlation between the level of education, parents’ occupation, maternal age, source of drinking water, and the type of floor house and diarrhea.Keywords: diarrhea, children under five years, sociodemographic factors, environmental factorsAbstrak: Diare masih menjadi masalah kesehatan di dunia. Masalah tersebut terlihat dari tingginya angka morbiditas dan mortalitas akibat diare pada anak di seluruh dunia. Pada penderita diare, zat-zat makanan yang masih diperlukan tubuh terbuang bersamaan dengan dehidrasi.

Physicochemical and Bacteriological Parameters of Borehole and Hand dug well water of Michika town in Michika Local Government Area of Adamawa State, Nigeria and environs were assessed to determine their suitability or otherwise for drinking and domestic purposes. Ten (10) water samples, five each from boreholes and hand-dug wells, from five selected areas in Michika town, were collected during the months of January and February 2018. The water samples which are extensively used for drinking and other domestic purposes, were randomly collected and the results were compared with WHO and NAFDAC standards guidelines for drinking water. These samples were analyzed for their physicochemical characteristics (pH, temperature, electrical conductivity, TDS, Turbidity, hardness), heavy metals, Escherichia coli (E. coli) and coliform counts. The results of the investigation revealed that the physicochemical and bacteriological parameters falls within the maximum permissible limits of NAFDAC and WHO guidelines for drinking water. The physicochemical concentrations were higher in borehole water than in hand dug well water; Lead and Cadmium were not detected in all the samples. All the water samples were free from feacal contamination except in Barikin Dlaka hand dug well which contained 0.05 ± 0.001 MPN/100 ml total coliform count which is below the WHO/NAFDAC maximum permissible levels. The suitability of water for domestic and drinking purposes indicated that the water samples were within the standards prescribed for potable water. However, there is need for routine checks to ascertain the suitability or otherwise of these water sources so as to forestall outbreak of water born diseases.

Background:: Globally, around 150 million people are still supplied with arsenic contaminated drinking water. As well as arsenic, the groundwaters effected often contain problematic concentrations of natural organic matter (NOM), which plays an important role in releasing As into the aquifer. This review thus explores the recent literature relating to the application of various nanomaterials to solve these drinking water supply problems, and highlights the work which still needs to be done. Methods:: After an extensive initial search of the literature, papers were selected based on their quality and relevance to the topic of this review: the use of magnetic nanomaterials based on pure magnetic materials, magnetic composites of carbon/graphene/biochars, polymeric matrices, metal-organic frameworks and mixed-oxide magnetic nanocomposites, as As adsorbents and as photocatalysts for NOM removal. Results:: 160 papers relating to the application of nanomaterials for As removal were reviewed, as well as 38 papers covering photocatalysts for NOM removal. These papers were organised by type of nanomaterial, and their important findings summarised. Although many authors have demonstrated effective solutions in the laboratory, the following areas still need to be addressed: the challenges posed by larger pilot and full scale continuously operated processes; the treatment of complex natural water matrices; which technologies will be required to economically separate nanoparticles from the treated water; whether the nanoparticles will be more economically and environmentally sustainable than other techniques available. Conclusion:: Despite these significant gaps in the literature, the body of work carried out thus far, as summarised in this review paper, strongly suggests that full scale treatment solutions applying (magnetic) nanomaterials may prove highly effective in the future for both arsenic and NOM removal.

Aloe vera drink is one of the processed drinks made from the aloe vera leaves, washed until the mucus is reduced and boiled with water. Good drinking water should not contain pathogenic bacteria or organisms that can endanger human health. Coliform is one of the bacteria that can cause disease in humans and is used as an indicator of the presence of pathogenic bacteria. This study aimed to find out the most probable number (MPN) Coliform bacterial in aloe vera drinks which has sold at the location of the sale on Budi Utomo Street, Pontianak City. Sampling used the random sampling method. The MPN test results obtained the lowest MPN/mL index value of 0.091/mL in the samples purchased at the minimarket, while the seven samples obtained at the sales location showed the highest MPN/mL index value of> 24.00/mL. It showed that the eight samples reached over the normal limits listed in SNI 01-3839-1995 based on the Republic of Indonesia Ministry of Health No. 907 / MENKES / SK / VII / 2002 concerning the requirements and supervision of the quality of drinking water which is not more than 0/100 ml.

Abstract Water is essential for life, and a satisfactory supply must be available to all. Improving access to safe drinking water can result in tangible benefits to health. This study analysed samples of water from meat, milk and fish production from Republic of Srpska (Bosnia & Herzegovina) sampled in the period 2018-2020. A total of 390 samples were examined. The aim of the study was to determine the microbiological status of water used in meat, milk and fish production in the republic, in order to identify the risks to food safety. Microbiological testing used methods BAS EN ISO 6222, BAS EN ISO 7899-2 and BAS EN ISO 9308-1/A1. The microbiological status of water used in the production of meat, milk and fish in the Republic of Srpska in the period 2018-2020 has significantly improved compared to previous years. It is important that the presence of pathogenic bacteria in the water is at a low level. However, there are concerns that almost one-fifth of the water comes from wells, which are not under constant surveillance. This is especially important given the possibility of well water contamination and consequent food contamination.
