Open Dumping of Muncipal Solid Waste and its Hazardous Impact on Soil and Ground Water

Open dumping sites which generates serious health risks. The main aim of this paper is to shoe the effects of that open dumping on ground water resource, soil quality. It was observed that the people living in this area have poor health like allergy, asthma, skin irritation and other gastro intestinal diseases. The focus of this study is to assess the contribution of open dumping in soil contamination, water contamination and its effects on human. Surface soil sample were collected from open dumping site Naregaon and nearby area. Significant modifications were observed in the soil properties of dumping sites. Soil at the disposal site shows high pH Electrical conductivity. Various heavy metal concentration i.e. Zinc (Zn), copper (Cu), Iron (Fe), manganese (mg).

ARSENIC AND OTHER METALS CONTAMINATION IN GROUND WATER RESOURCE IN DAK NONG PROVINCE, VIETNAM

This study aimed at understanding the concentrations of selected heavy metals including arsenic, iron, manganese, cadmium and mercury in groundwater used for domestic purposes in Dak Nong Province of Vietnam. A total number of 572 groundwater samples including 61 duplicates were collected during October, 2018 – April, 2019. The collected samples were measured onsite for pH and preserved with 2% HNO3 before being analyzed in the laboratory for heavy metals by inductively coupled plasma mass spectrometry. The relative percent differences of all duplicate samples were less than 30%, indicating that the analytical results were within acceptable ranges. The average concentrations of As, Fe, Mn, Cd, Hg and Pb in groundwater were 9.53±46.36, 307.1±1,178, 166±478, 4.66±6.2, 1.0±1.8 and not detected, respectively. Amongst all the analytical results, however, some values on the concentrations of studied metals exceed the Vietnamese regulation values for groundwater quality and for domestic use requirements. The research results therefore suggest that groundwater containing rather high concentrations of heavy metals at the studied area should not readily be used for domestic purposes without proper treatments.

PENDUGAAN POTENSI AIR TANAH WILAYAH PESISIR KABUPATEN PASIR KALIMANTAN TIMUR

Coastal aquifers are an important ground-water resource for urban, fisheries, and agriculture areas. Coastal aquifer system at coast of Tanah Grogot Regency, at East Kalimantan Province, is important to community, but existing aquifers are not productive as ground water resources and therefore to meet community needs of water, a geoelectricity survey need to be conducted to find aquifers and this information will be used for development of water resources planning and method to be used for geoelectricity survey is rock layer resistivity. Result of this survey will identify aquifer layers as source of water.

Domestic well database development and integration into a GIS: an approach for managing ground water resources

Connecticut is dominated by rural communities which rely upon individual domestic wells in fractured crystalline bedrock for water supply. The individualized nature of ground water usage has made ground water resource planning on a regional or townwide basis non-existent. In recent years there has been increased development and concerns expressed regarding the sustainability of the fractured crystalline rock water supply and its quality, and the need for ground water resource planning. In this study, using a rural quadrangle in eastern Connecticut, we have developed a database system that is tied to a geographic information system that can be used to help manage and assess ground water conditions. The data in the database were derived using available water completion reports and water quality reports. Data query schemes were developed to screen for data entry and reporting errors. The information maintained in the database has been analyzed to derive products on well yield, well depth, and water elevation. These products are beneficial to town planners, local sanitarians, developers, homeowners, and drillers. They can improve and facilitate decision-making concerning future rural development to ensure ground water sustainability.
