Potable ground water quality is at risk due to contamination by pollution, sewage, industrial effluents along the nearby areas of Mula-Mutha river banks in eastern metropolitan region of Puneand needed treatment especially disinfection for making it domestically usable. The phytoremediation is one of the important useful method when considered for treatment of water in rural area. The study involved monitoring the quality of ground water in the selected areas along the banks of the river using physicochemical and biologicql parametersin continuation with our earlier studies. For the disinfection treatmentthe commonly found plantsin the area viz. Neem, Tulsi, and Amlawere selected and for the water samples, onsite river water samples and bore well water samples were used. The plants leaves were extracted by water and alcohol and the extracts in dose response manner were used to treat the water. The treated water was monitored for presence of Total coliform and E.coli, the indicators of contamination, using petri film method. The resultsshowedrandom presence of total coliform and E.coli in bore well water samples indicating contaminationand the need fordisinfection.The disinfection study showed that alcoholic leaves extracts were more potent in disinfecting the water samples than aqueous extracts. The complete disinfection by alcoholic extracts was shown at concentration of 21.12mg, 42.8mg and 24.07mgfor Tulsi, Neem and Amla respectively.

Brownish yellow is one of the characteristics of bore well water which indicates a high concentration of iron (Fe) that will affect human health and damage the aesthetic value. This study aims to purify the bore well water by reducing the concentration of Fe metal by adsorption of chicken bone activated carbon (CBAC) and implementing the results of research on the material of colloidal adsorption properties at Pekanbaru Telkom Vocational High School. CBAC is made through 3 steps namely dehydration at 50oC, carbonization at 400oC and activation with HCl, formic acid and NaOH pa. Each 1 gram of CBAC is mixed with the volume varied by 5; 10; 15; 20 and 25 ml. Measurements of Fe metal concentrations were carried out using Atomic Absorption Spectrophotometer (AAS) and the data obtained were then analyzed descriptively through tables and graphs. Maximum adsorption of CBAC was obtained in 20 ml of bore well water with a percentage reduction 99.92%. All results of treatment meet Fe metal quality standards as stipulated in Republic of Indonesia Minister of Health Regulation No. 416 of 1990. Analysis of student response questionnaires based on questionnaire analysis techniques obtained a cumulative value of 88.62% (very good).

Abstract The accumulation and translocation of trace metals in soil and in sugarcane crop irrigated with treated effluents from sugar industry compared to soil and sugarcane crop irrigated with bore-well water were determined. In the present study the impact of irrigation with treated effluent from the sugar industry on the trace metal contamination of sugarcane juice was assessed. It revealed that the mean concentrations of Cd, Pb, Cu, Mn and Zn in the soil of fields irrigated with effluent and in juice from sugarcane grown on such fields were higher than those from bore-well water irrigated fields. The concentrations of trace metals in treated effluent exceeded the permissible limits of the Indian standards (Central Pollution Control Board-2000). The concentrations of Cd, Pb, Cu and Zn in juice of sugarcane grown on fields irrigated with effluent also exceeded the permissible limits of Indian standards and WHO/FAO expert committee recommendations. Their concentrations in juice of sugarcane grown in fields irrigated with bore-well water were within the limits of safety, except for Cd. The transfer factor for Zn was considerably higher than those of the other trace metals. The metal concentrations of sugarcane juice showed significant correlations with those of soil, which was not the case when bore well water was used for irrigation.

The present study observed the accumulation of heavy metals in Brassica juncea irrigated with paper mill effluent (PME) and control Bore well water (BWW). The soil was treated to five rates of effluents viz. 10, 25, 50, 75 and 100 ml/Kg soil. It was revealed 100% PME irrigation of soil increased Pb (+46.44%), Cr (+83.21%), Ni (+38.43%) and Cd (+78.92%). The enrichment factor (Ef) for Cr and Cd showed moderate enrichment with 10% to 75% PME irrigated soil, except Cr (5.96) which showed significant enrichment with 100% PME irrigated soil. Ef value for Pb and Ni showed deficiency to mineral enrichment with different concentrations of PME irrigated soil. The maximum accumulation of Pb (42.66±2.05 mg/kg), Cr (39.80±5.95 mg/kg), Ni (88.64±11.29 mg/kg) and Cd (5.85±0.29 mg/kg) were recorded in leaves of B. juncea, while that of Pb (43.85±3.46 mg/kg), Cr (48.59±3.81 mg/kg), Cd (6.74±1.22 mg/kg) with 100% and Ni (74.93±2.54 mg/kg) were recorded with 75% PME after 60 days in roots of the B. juncea. Ef value was found maximum for Cr (5.08) in leaves and for Pb (6.64) in roots, while the Translocation factor (Tf) was found maximum for Pb (2.45) in root of the crop irrigated with PME. The use of PME with proper dilution and with the metallic concentrations in permissible limit can be used as biofertigant for irrigation of B. juncea.
