study of Water quality of Springs in petra region jordan a three year follow up
Water Resources Management, 2007Co-Authors: Omar Ali AlkhashmanAbstract:Petra region area was located in south part of Jordan has grown and urbanized rapidly. This area depends on the groundWater as a Water resources. This study was undertaken to assess the physical, chemical quality of spring Water of Petra region during a 36-months survey (September 2002 to September 2005). The samples were analyzed for temperature, conductivity, dissolved oxygen, pH, major cations (Ca 2+ , Mg 2+ , K + , and Na + ), major anions (Cl − , NO − 3 , HCO − 3 , SO 2− 4 , PO 3− 4 , F − ) and trace metals (Fe 2+ , Al 3+ , Cu 2+ , Ni 2+ Pb 2+ , Zn 2+ and Mn 2+ ). Water quality for available Springs in the study area showed high salinity due to longer period of contact with rocks. The chemistry of spring Water samples were alkaline earth Waters with prevailing bicarbonate and alkaline earth Waters with prevailing bicarbonate chloride. Some Springs showed that elevated nitrate, sulfate contents which could be due to percolation from septic tanks, cesspools and irrigational activities. The infiltration of wasteWater from cesspools and septic tanks into groundWater was considered the major source of Water pollution. The results showed that there were considerable variations among the examined samples with respect to their physical and chemical parameters, which lie below the maximum permissible levels of the Jordanian and WHO drinking Water standards. The results indicate that the trace metals of Springs Water of Petra region do not generally pose any health or environmental problems. Copyright Springer Science + Business Media, B.V. 2007

Alice Springs Water Allocation Plan 2016 - 2026
2016Co-Authors: Kate HeppnerAbstract:This document, the Alice Springs Water Allocation Plan (the plan) has been developed to provide an adaptive management framework for the allocation of Water resources. The plan applies to all surface Water and groundWater within the Alice Springs Water Control District (the district), and incorporates the precautionary principle as far as possible. The four principal objectives of the plan are to: - Maintain public Water supply - Protect the environment - Support Indigenous culture and communities; and - Ensure sustainable development

Wetlands of the Alice Springs Water Control District
2020Co-Authors: Angus W. DuguidAbstract:This report describes wetlands of the Alice Springs Water Control District (ASWCD). The primary purpose of this report is to support Water allocation planning in the ASWCD, so that the natural values of surface Waters can be given due consideration. The report provides a summary of the district’s wetlands that will also be useful for people with a general interest in nature and wetlands. The different types of wetland that occur are described with examples, along with known biological values. Wetlands of particular conservation significance are described.

Water resource characteristics of epikarst spring in rocky desertification area — A case study in Longhe, Guangxi, China
2011 International Symposium on Water Resource and Environmental Protection, 2011Co-Authors: Yan Deng, Zhongcheng JiangAbstract:Epikarst Water is the main source for drink and irrigation in karst fengcong depression area in southwest china. Investigating, exploring and utilizing epikarst Water is a hot issues for scholars in recent years. The epikarst spring in the Longhe rocky desertification area in SW China was selected for this study. Continuous auto-monitoring of the spring's discharge and rainfall had been done from 2003 to 2005. The results indicated that Flux of epikarst Springs is small and will stop flow in a long time and has a sensitive response to rainfall, at the same time,epikarst Springs Water resource in epikarst area distribute unequably in different season. The storage and derivation technique, which is a economice, effective and universal way, distribute widely in karst mountain area in SW china. At the same time, adding forest coverge in catchment area, developing Water conservation forest, enhancing the regulation and storage ability of epikarst zone to Water cycle, increasing Water resources of epikarst Springs and extending its flow time are the basic way of advancing the effective utilization of epikarst Water resources.

Water quality of few Springs in outer himalayas a study on the groundWater bedrock interactions and hydrochemical evolution
Groundwater for Sustainable Development, 2015Co-Authors: Md Arzoo Ansari, Archana Deodhar, Saravana U Kumar, Vinod Singh KhattiAbstract:Abstract Springs in the Kandela valley in a part of outer Himalayas, India were sampled and analyzed for their major ion chemistry in order to assess their Water quality, possible origins and hydrochemical evolution of the Waters. Analyses of Springs Water samples show that the concentrations of Ca 2+ exceed that of Mg 2+ in all Springs; the concentrations of Na + are next to Mg 2+ and are higher than that of K + ; HCO 3 − and SO 4 2− are most dominant among anions compared to Cl − and NO 3− . The spring Waters are categorized into two end-member hydrochemical facies: (1) pH-mildly alkaline, Ca–Mg–HCO 3 Water with low to moderate EC; (2) mildly alkaline, Ca–Mg–HCO 3 –SO 4 Water with moderate EC. The facies 1 Water occur mainly due to easy dissolution of carbonate minerals. This facies may occur during recharge which results in low ionic concentration in shallow zone in regional carbonate aquifer. The facies 2 Waters are chemically distinct from Waters in the valley. PHREEQC geochemical modeling show that all Water are supersaturated with respect to carbonate mineral but are undersaturated with respect to evaporite and precipitation of carbonate, dissolution of evaporite and ion exchange are important process during the groundWater–bed rock interactions and hydrochemical evolution. GroundWater generally occurs under Water table condition and is fit for drinking and irrigation purposes in study area.
