Kronologi Kualitas Air Tanah Dangkal di Dataran Fluvial Vulkan untuk Permukiman Daerah Kabupaten Klaten Jawa Tengah

Abstract

Laboratory analyzes of unconfined ground water in fluvio volcanic plains for settlement aims to analyze the chronology of groundwater chemical elements .Sample method base on level of settlement land unit. Analysis of the results was based on lithology, tectonic earthquake effects, 2006, antopogenik against the elements (physics, chemistry, biology and electrical conductivity) of unconfined groundwater. Results of analysis: 1) In the past pleistoten sea water trapped occurs simultaneously formation process of South plateau Java; being on the sea water Alluvium period covered by sediments and aquifers formed saltwater and freshwater aquifer is at the top. 2). Unconfined groundwater quality by natural and anthropogenic processes results indicated the nature (physics, chemistry and biology) and the groundwater electrical conductivity in 1000 mmohs. 3). Mixing of salt water and unconfined groundwater is the result of natural processes, anthropogenic and tectonic processes 2006 earthquake demonstrated the nature (physics, chemistry, biology) and groundwater electrical conductivity> 1000 mmhos.
