Hydrological potential at Xichu county was described. It is considered the main water reserve of the state of Guanajuato, but paradoxically inhabitants don`t have water supply minimal infrastructure. At Xichu is possible to find the most contaminated site with arsenic in Mexico: La Aurora mine tailings. The aim of this study was to know hydric exploitation potential (annual rain volume and fluxes of seven springs) and to describe danger scenarios (cartography of mine tailings of La Aurora, hydrological conditions of two main channels and to simulate maximal runoff using real rains data). Springs at karstic and fractured rocks produce significative volumes that can supply potable water to population all year. Mine wastes represents at least 600 000 t of materials that can be eroded. Rains over this region favor threat conditions by slides or remotion mass processes. It lacks hydrologic instrumentation to predict risks and take opportune decisions.

Potential Use

The water crisis in the state of Selangor has prompted the state water authority to use water from abandoned mining pools as an alternative resource of raw water supply. In this study, the potential use of the mining pool water has been assessed to evaluate its safe use for potable water consumption, which is the source of raw water to be supplied to water treatment plants. Assessments were made between sampling sites that include abandoned mining pools, active sand mining pools, and the receiving streams (two tributaries and the main river, Selangor River) within Bestari Jaya catchment, Selangor River Basin. As anticipated, some concentrations of metals were found in the active mining pool and in its discharge, such as iron, manganese, lead, copper and zinc. However, the trace elements were found at very low concentrations or below detection limits in the abandoned mining pools and in the rivers. It was found that generally the quality of the water in the rivers (upstream of water intake of the water treatment plants) was well below the recommended guideline limits set out by the Malaysia Ministry of Health for untreated raw water, and therefore is safe for potable water use.

The last decade has brought many changes to Colorado's water supply outlook. Despite the recent economic recession, the state has experienced significant population growth, and Colorado's population is expected to nearly double within the next 40 years. Other pressures on Colorado's water supply include severe drought, a desire to meet multiple needs (i.e., municipal, environmental, recreational) with existing resources, and impacts to agriculture due to water shortages, urbanization, and transfers to new users. To address these challenges, the Colorado Water Conservation Board (CWCB) has undertaken a visioning process to explore solutions to these future water supply challenges. As part of this process, CWCB has led the state in identifying demand and supply strategies to meet the state's future water needs while considering agriculture and the environment. These strategies have been combined into varying portfolios that include methods such as conservation, local water projects, new Colorado River development, and agricultural transfers. This paper details the development and evaluation of these portfolios and describes stakeholder's efforts to balance meeting Colorado's water needs in the future.

AbstractUranium concentration in the ground water samples from the district of Tiruvannamalai, Tamil Nadu, was measured using an LED fluorimeter. All the samples were qualified as potable water from the radiological perspective. Though some samples showed mild chemical toxicity, they are still safe for ingestion. Different risk coefficients were calculated, and they were compared with recommended safety limits specified by various agencies. Software tools such as QGIS 15, GraphPad Prism 8 and Surfer 15 were employed for developing maps and plots.

The paper reports the main findings of a study, designed to develop a better understanding of institutional variations in working with the demand responsive approach (DRA) in rural water supply in the state of Odisha in India. Data for the paper were collected from twelve village communities, where water is being supplied either through their community based institution or through the local government institution of the Gram Panchayat. The findings suggest that the two types of institutions performed differently in implementing the DRA. It depicted that the DRA under the broader rubric of institutional reforms in the water sector has failed to address the question of social inequality, and rather had reinforced and extended the already existing inequity of Indian society to access to safe and secure drinking water in rural areas. The study highlights that participation, cost recovery, full operation and management transfer may be an efficient proposition, but not sustainable in the long run without proper investment in institution building and support from the state, especially in provisioning of basic services like drinking water to rural poor.
