Rogachevskaya Ciencias de la Tierra vadose zone Groundwater recharge vulnerability assessment The Snake River Aquifer System in eastern Idaho is one of the largest and most important regional water supplies within theUnited States. Safeguarding the Snake River Aquifer System from pollution underlying the Idaho National Engineering andEnvironmental Laboratory (INEEL) is of critical importance to the U.S. Department of Energy. The present paper contains theresults of the investigations. Its tasks were: analyze the impact of natural factors on groundwater vulnerability; develop the map ofgroundwater vulnerability to contamination; indicate contaminated sites for risk of groundwater contamination using the map.Main attention was paid to vadose zone (aeration zone), that determines potential danger of contaminant penetration from the landsurface to groundwater table. Assessment of vadose zone protection role was based on the following controlling factors: passivefactors depth to water and conduct properties of unsaturated medium; active factors recharge, including its main parts: precipitationand irrigation. Vulnerability assessment was done step by step by compiling a series of maps. Combining vadose zone mapand the map of groundwater recharge at Eastern Snake River Plain, the resulting map reflecting all above mentioned factors werereceived. The Point Count System was a main concept of vulnerability assessment. Influence of each factor was specified bydifferent numbers (Rank), which were determined by expert assessment. The lesser the Rank, the more favorable situation is withrelation to groundwater vulnerability. Groundwater vulnerability is characterized by Ranks sum that could vary from 8 to 40 inregion under investigation. Total Rank sum characterizes groundwater vulnerability to contamination. 2004 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56843419 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.4 Vol.43 |
