Textile Industry is one of the most important and largest industrial sectors in Pakistan. It has a high importance in terms of its environment impact, since it consumes large quantity of textile industrial processed water and produces highly polluted discharge water. The textile industry uses high volume of water throughout its operation, from the washing of fibers to bleaching, mercerizing, dyeing, printing and washing of finished products. A process data collection was performed and integrated with a characterization of the process effluents in terms of treatability and reusability. In order to evaluate properly the wastewater loading, on analysis course was set. The samples were collected during four months period of time i.e. November, December, January and February 2009-2010 from the seven samples were collected from different textile mills and analyzed for various parameters such as Total Dissolved Solids(TDS), Chemical Oxygen Demand(COD), Biochemical Oxygen demand(BOD), pH, Electrical Conductivity(EC), and heavy metals like Cadmium(Cd), Chromium(Cr), Copper(Cu), Iron(Fe), Manganese(Mn), Nickel(Ni), Potassium(K), Phosphorous(P), Sodium(Na), Sulphur(S), Zinc(Zn) were found in within the limits. Concentrations of all these metal ions in the effluent were above the recommended NEQS. It was therefore concluded that textile effluents were highly polluted.

A regional gravity anomaly, based on element shape functions used in finite element analysis, is developed. The regional gravity is approximated by a weighted sum of discrete gravity values at eight stations coinciding with the eight nodes of a second‐order or at twelve stations coinciding with the twelve nodes of a third‐order isoparametric element superimposing the map space. The computations are carried out on a reference space with the shape functions acting as weighting factors, and subsequently translated to the real map space. In this technique, no observed gravity data lying inside the survey area enter into the regional computation. Tests on the gravity field in Harris County, Texas, a well known hydrocarbon prospect during the 1940s, and the Klamath Mountains and the Cascade Range in California confirmed the efficacy of this method.

A theoretical solution is obtained for the problem of a two-layer earth with transitional boundary.In practice, the transition layer can stand for the weathered zone in hard rock areas where the degree of weathering diminishes with depth. Master curves and tables of data are presented for the case when the lower half-space is infinitely resistive.In many instances where the geological section can be approximated by horizontal layers, the boundaries between the layers are not sharp but are transitional in nature. Over much of the area in peninsular India, hard granitic and basaltic rocks occur either as exposures or concealed under a thin cover of soil and weathered in-situ material. While the exposures are sometimes worked or quarried for road and building material, it is the latter-namely, the regions of soil and weathered cover-that is important from groundwater and agricultural points of view. A typical section in such regions consists of a transported soil cover of a few meters' thickness, underlain by a transitional layer of weathered granite or basalt of gradually increasing freshness, and followed finally by the unaltered highly resistive bedrock. The top soil cover is more or less uniform with a resistivity of a few ohm-meters. Within the weathered layer, this resistivity increases-with approximate linearity-with depth, until the unweathered rock with a resistivity of 500 to IOOO ohm-meters is reached at depths of about 15 to 25 meters.The above conditions are illustrated in Figures ~(a) and (b), which represent field measurements in granitic terrain. Resistivities were measured along the vertical walls of dug wells with a Wenner electrode arrangement of Io-ems spacing. In Figure r(a), the top soil is about 2.5 meters thick and has a uniform resistivity of z to 3 ohm-meters, although, very near the ground surface, the resistivity increases due to lack of moisture. If one neglects minor and local variations, an approximately linear increase of resistivity with depth within
