Use of groundwater from private wells in households has increased considerably, owing to a better cost/benefit ratio than that of water provided by local utilities for a fee. However, this water is usually untreated, which makes it a vehicle for diseases. Thus, monitoring this water is necessary to ensure its integrity and quality. We aimed to evaluate the physical, chemical, and microbiologica...

This study documents the response of 6500 rural households in a 25 km(2) area of Bangladesh to interventions intended to reduce their exposure to arsenic contained in well water. The interventions included public education, posting test results for arsenic on the wells, and installing 50 community wells. Sixty-five percent of respondents from the subset of 3410 unsafe wells changed their source...

To the Editor, The Indian Medical Gazette. Sir,?I was very interested to see the article by mv old friend and brother-officer Lieut -Col. G. G. Jollv who is now Director of Public Health in Burma, in your last issue. His article gives an interesting account of a very common occurrence in connection with deep wells. He observes that under certain climatic conditions there is a decided falling of...

For regional models, the shallow water table surface is often used as a source/sink boundary condition, as model grid scale precludes simulation of the water table aquifer. This approach is appropriate when the water table surface is relatively stationary. Since water table surface maps are not readily available, the elevation of the water table used in model cells is estimated via a two-step p...

abstract irregular extraction from agricultural wells around parishan lake, moreover fall of groundwater surface and water salty, would affect the level of lake water and move lake water into wells. in this study we have evaluated the externalities of extraction from agricultural wells around the lake. therefore feedback effect is considered between agricultural activity around the lake and lev...

By Surgn.-Capt. P. IIeiiiu, m.d., f.r.s.e., d.p.h. Camb., Fellow, Santy. Inst., Fellow of British Inst., Pub. Health, Health Officer, Chudderghat Municipality. 1 iieiie are three varieties ot wells, shallow or superficial, deep and artesian. The last mentioned may be considered a variety of deep well, and we will dispose of it with a few words, for the reason that artesian wells have, up to dat...

S OF SCIENTIFIC AND TECHNICAL PAPERS2 Reprint 107. THE DRAINAGE OF LAND OVERLYING ARTESIAN BASINS. By W. Gardner. O. W. Israelsen, and W. W. McLaughlins • In SOIL SCIENCE, Vol. 26, No.1 (July, 1928), pp. 33-45. The methods of hydrodynamics are used in an effort to calculate the influence of drain tile and of wells on the water-logged condition of fine-textured .oils due to hydrostatic pressure in

The study investigated the physico-chemical and bacteriological qualities of water from wells sited in close proximity to waste management systems in the Ahanta West District. GPS was used to determine the geographical location of wells and waste management system. The physic-chemical and bacteriological parameter of samples of water taken from these wells were determined at the laboratoryand c...

Corrosion and scaling in drinking water sources can lead to economic and health damages. These processes produce by-products in distribution systems, reduce chemical water quality, and are the cause of health issues among consumers. The aim of this study was to evaluate the corrosion and scaling potential of water supply sources of Marivan villages, Iran. In total, 106 water samples were collec...

Assessing the quality of groundwater is important to ensure the sustainablesafe use of these resources. However, describing the overall water quality condition isdifficult due to the spatial variability of multiple contaminants and the wide range ofindicators (chemical, physical and biological) that could be measured. Therefore, in thiscase study, some water quality parameters including Na, Mg,...
