The water quality of the Kahayan River is still below the criteria for clean water quality standards. One of the treatments to improve water quality is snail shells as adsorbents of heavy metals Fe and Zn are categorized as pests on fruit plants. The object of this research is the snail shell activated charcoal is used to improve the quality of river water on heavy metals Fe and Zn. The mass variation of snail shell activated charcoal weighing 0 grams, 5 grams, 10 grams, and 15 grams. The research process is divided into the Preparation Stage and Implementation Stage, where the implementation stage consists of making snail shell charcoal, making HCl solution, activating snail shell charcoal, and absorbing snail shell activated charcoal. Snail shell activated charcoal plays an active role in decreasing Fe and Zn concentrations. At 5 mg of snail shell activated charcoal was able to reduce 53% Fe concentration and 69% Zn concentration. Snail shell activated charcoal with a mass of 10 mg and 15 mg was able to reduce Fe concentration by 82% and 84%. Testing the Zn concentration in the mass of 10 mg and 15 mg was not read optically, due to the limited accuracy of laboratory equipment.

Taking in consideration that drinking water is a vital element without which the normal existence of humans and other living things in our planet cannot be thought of, we are motivated to research the wells and springs used for drinking in the villages of Bajgora, Kovacica and Kaqandoll. The suspicion that the waters of this mountain massif contain heavy metals due to the presence of mineral ores also prompted us to investigate the degree of presence or not of heavy metals in these waters. To assess the water quality of these wells, in the monitoring network that includes these three villages, we have pinpointed five monitoring points, determining the organoleptic, physic-chemical, and microbiological and heavy metal parameters. During the research process, in order to evaluate the water quality as accurately as possible, classical and instrumental methods of chemical analysis were applied. We have compared the results of the analysis with the standard values of AI16 / 2012- Administrative Instruction of Kosovo that has to do with the quality of water for human consumption and that is in full compliance with EU Directive 98/83 EC. The obtained results denote the presence with heavy metals of Pb, Zn, Cd and Ni, in four of the five samples taken for research. Therefore, we have come to the conclusion that the presence of these metals results as a consequence of the geological composition and ore-rich underground layers of this mountain massif.

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).

Buriganga River

This work has been conducted to evaluate the water quality of the Buriganga river. In situ water quality parameters and water samples were collected from 10 locations in January 2016 and analyzed later in laboratory for water quality parameters such as pH, Eh, EC, TDS, cations (Na+, K+, Ca2+, Mg2, As3+), anions (Cl-, HCO3-, NO2-, NO3-, SO42-, F-, Br-, PO43-), heavy metals (Cr2+, Pb2+, Zn2+, Cd+2, Fe2+, Mn2+) to see whether or not the level of these parameters are within the permissible limits. The average values of pH, Eh, EC and temperature were 7.31, –214.9 mV, 928.9 μs/cm and 21.4°C, respectively; the average concentration of Na+, K+, Ca2+, Mg2+, and As3+ were 109.62, 13.38, 46.78, 13.98 and 0.018 mg/l, respectively, while the concentrations of Cl-,HCO3-, PO43-, SO42-, NO3-, NO2-, F and Br -were 79, 331.06, 2.22, 84.32, 0.0254, 0.058, 0.224 and 0.073 mg/l, respectively; and the concentration of heavy metals Pb2+, Zn2+, Fe2+ and Mn2+were 0.28, 0.053, 0.17 and 0.23 mg/l, respectively. The study indicates that most of the parameters are within the permissible limits set by Bangladesh water quality standard. The concentrations of K+, Mn2+, and Pb2+ were beyond the permissible limits meaning that that the water of Buriganga is not safe for drinking. The people living beside Buriganga river should be more cautious about using the polluted/contaminated river water. The concerned authorities should take urgent necessary steps to improve the degraded water quality of the river considering the ecological, environmental and economic implications associated with it.

Malwa region of Punjab state, India has become the center of water borne diseases due to excessive use of pesticides, chemical fertilizers, heavy metals, industrial toxins that cause toxicity in water. The main contamination in ground water is by physico-chemical parameters and heavy metals i.e. pH, total dissolved solids, total alkalinity, total hardness, calcium, chlorides, fluorides, arsenic and lead. The contamination of ground water with heavy metals causes health hazards to humans and animals. Due to lack of adequate facilities and resources for the management and handling of waste, the ground water contamination has been increased. In the present study, assessment of ground water quality was carried out in the villages of Ferozepur district of Punjab state, India. With main emphasis on analyzing the groundwater parameters of Ferozepur district which are responsible for health hazard to humans and animals. Various groundwater samples were collected randomly from the villages of Ferozepur district and analyzed for pH, total dissolved solids, total alkalinity, total hardness, calcium, chlorides, fluorides, heavy metals (arsenic and lead) using standard procedures. The concentrations of calcium, chlorides, fluorides and pH were within the permissible limits, whereas, alkalinity and total hardness were observed beyond permissible limits in most of the water samples. Even among majority of the samples taken, the concentration of arsenic and lead was found within the permissible limits. Results showed that the ground water samples collected from depth ranging from 100 to 360 ft, recorded values within permissible limits for drinking purpose as prescribed by WHO. Further, ANOVA has been applied on analysis results to study the effect of pH on fluoride and chloride, depth on fluoride and chloride and depth on arsenic and lead. Also, to adjudge the overall quality of water in Ferozepur district, the water quality index (WQI) has been calculated on the basis of large number of physico-chemical characteristics of water. The water quality index of ground water in Ferozepur district has been calculated to be 107. The value is close to 100 so the quality of ground water in Ferozepur district can be categorized under 'Good Quality' water.
