Drilling at unconsolidated layer can make the aquifer disturbed and reduce a productivity of groundwater well. Surge block and air surging were applied to a pumping well located in Jeungsan-ri, Changnyung-gun, to improve a well efficiency by removing clogging and fine-grained slime. Two experimental log-linear equations, y1= ?0.1769 ln (x1) + 0.4960 and y2= ?84.3358 ln (x2) + 512.8162, were proposed in this site, in which x1 and x2 are the number of surging event, y1 is the amount of slime, and y2 is a recovery time of groundwater level after air surging. Well loss exponent (P) decreased after surging, from 3.422 to 1.439, and the groundwater inflow from aquifer happened in all directions around a well with gradually increasing the homogeneity in a local aquifer's hydraulic property. It was revealed that long-term well development should be done in the pumping well which is located in solidated sediments to increase a well productivity. |
