摘要
渗滤液和固体废物是土壤和地下水污染的主要来源。渗滤液的影响评估是土壤和地下水研究的一个活跃领域。本研究利用二维电阻率成像技术评估了尼日利亚阿南布拉州Nkwele-Ezunaka农场的渗滤液迁移程度。研究区域位于东经6°51′27”~ 6°59′37”，北纬6°13′18”~ 6°20′27”，面积约60 km2。利用数字读出电阻率仪(ABEM SAS 1000)进行了电阻率测量，共测量了五条剖面线。所得数据用RES2DINV软件进行解释。在二维电阻率剖面上圈定了污染渗滤液羽流为低电阻率带(小于80.0 Ωm)。测定的渗滤液最大渗透深度为10.6 m，不能渗入研究区内的地下水。研究区地下水流动呈现西向东的趋势。
2D Resistivity Imaging for Leachate Migration in Nkwelle-Ezunaka Farm Estate, Southeastern Nigeria
Leachate effluence from wastewater Leachate migration and solid waste are major sources of soil and groundwater pollution. Assessing the impact of leachate is an active area of soil and groundwater research. This study evaluated the extent of leachate migration at Nkwele-Ezunaka Farm Estate in Anambra State of Nigeria using a 2D resistivity imaging technique. The study area lies within longitude 6° 51' 27'' − 6° 59' 37'' E and latitudes 6° 13' 18'' − 6° 20 '27" N and covers an area of about 60 km2. A total of five profile lines were carried out in a resistivity survey using a digital read-out resistivity meter (ABEM SAS 1000). The data obtained were interpreted using RES2DINV software. A contaminant leachate plume was delineated in 2D resistivity sections as low resistivity zones (less than 80.0 Ωm). The maximum depth of penetration of leachate determined was 10.6 m and hence could not penetrate the groundwater in the study area. The groundwater flow in the study area was revealed to be in the West-East direction.
