The research is aimed to analyze leachate, surface water and ground water characteristics around  Galuga landfill site, Bogor District. Water samples had been taken in dry season of 2014 and in the end of rainy season of 2015 from several sites in areas around Galuga landfills which included leachate water, surface water, and ground water.  Leachate, surface water and ground water had   temperature and pH in normal ranges; whereas nitrate and Pb contents were high to very high levels, especially in  site adjacent to waste piles. The concentrations decreased in line with increasing distance from waste piles. Higher content of nitrate in leachate occurred in dry season, but in well water it was found in rainy season. Meanwhile,  Pb content in well water were high, both in dry and rainy seasons. Concentrations of nitrate and Pb in leachate water were higher than wastewater quality standard, so that the leachate water were not safe to be discharged directly to natural water body. The high content of nitrate and Pb caused the well water unsuitable to be consumed without water treatment processing.

Problem on the road access landfill at Balang Island II Bridge is the landslide at STA 23+025 on left side slope (BH-1) caused by a swamp pond on the roadside. The landfill that cutted into the swampy area made the water get stuck on one side (water could not flow to the original condition). The research method is the form of direct observation in the field which focuses on the results of information and laboratory testing which is then processed and analyzed. The analysis obtained that the soil type on the spot is clay with N-SPT 6 – 29. There are 2 alternatives solutions for the problem. First, if there is a ROW problem, the treatments are watercourse, adding counterweight, wooden pile under the landfill and one layer Geotextile PP 50 (initial ground water level on exsisting condition with 90,4 kPa loads). Second, if there is no ROW problem, the treatments are watercourse, adding counterweight, wooden pile under the landfill and one layer Geotextile PET 100 (initial ground water level on top of landfill with 90,4 kPa loads). Based on technical analysis, the second solution was chosen because it has bigger safety factor, smallest settlement value, and shorter time implementation. However it is still need more detail technical justification to strengthen the desicion.

Abstract This experiment considers the seven different stages of textile dyeing effluents on tomato crop production in order to diminish the excess effluent treatment plant (ETP) cost and farmers net input cost. Seven different stages waste water (WW) with ground water (control) were collected and analyzed for physiochemical as well as heavy metals properties. T8 (mixed effluent) crossed the limit of agricultural standard for almost all physiological parameters such as TDS, TSS, EC, BOD, COD affording the highest value. T8 also delivered the highest cl- and heavy metals like Cd, Ni, Cr followed by T4 (2nd wash after bath drain) < T7 (Fixing treatment water). As a consequence, these provided comparatively higher enrichment factor (EF), pollution load index (PLI) and sodium absorption ratio (SAR) to transform fresh soil into “severe” and “slightly to moderate” saline. Correlation matrix demonstrated that EF and PLI of heavy metals (except Cd, Ni) were negatively related to yield, while positively related to SAR and fruit abortion. Although T6 (2nd wash after soaping) performed better in respect to growth, yield, yield attributes and nutrient use efficiency, principal component analysis (PCA) expressed that T2 (2nd wash after scouring and bleaching) and T3 (enzyme treated water) also belong to T6 and T1 group (ground water). Therefore, T2, T3 and T6 could be used to vegetable crop production up to some extent and to reduce ETP and agricultural input cost.

Abstract Although flood hit the entire part of Chennai, Tamil nadu some three years ago, the quality of water is still found to be worse because of major inundation in these areas. The current inspection deals with the physico-chemical analysis of the ground water samples collected from ten locations in Neelangarai and Triplicane area in Chennai, Tamil Nadu and assessed using Heber Water Quality Index (HWQI) in the post tsunami circumstances. The factors examined were pH, fecal coliform, total dissolved solids (TDS), dissolved oxygen (DO), temperature biochemical oxygen demand (BOD) and turbidity. In addition to these parameters, pointers like electrical conductivity and salinity were also taken into consideration. The over all HWQI outcomes for all the trials in Neelangarai area were determined between 65.02 and 72.25 and Triplicane area was 66.64 - 70.71, which suggest that all the samples are medium to good in quality and could used for human consumption.

The environmental implications of rainfall pattern in replenishment of ground water system of Saharanpur region, located in western Uttar Pradesh, have been discussed. The mathematical analysis of rainfall dissimilarity of Saharanpur region for a period of 50 year (1959 to 2008) display a quite good range from 497.70 to 4357.5 mm with an annual average rainfall value of 1209.8 mm. The positive trend of departure from the computer value of average annual rainfall exhibits appropriate periods for recharge of ground water reservoir. The recorded data of annual rainfall during the last 3 year reveal values below the calculated annual average rainfall, pointing out negative trend. The statistical analysis of rainfall data involves computations of various statistical parameters, which also support the negative trend of rainfall. The prediction of expected future rainfall trend for a period up to 2018 has been made, which indicates a negative trend. The proposal have been incorporated to implement a plan for augmentation of ground water resource and also to develop possibilities of rainwater harvesting.
