| Abstract: | Sea water intrusion has occurred along the northern coast from Haijiao Avenue to Sichuan Road in Beihai City.Sea water intruded into the inland aquifers from north to south and east,and extended to Well S31 locating to the south of Haijiao Avenue in early 1989.Until March,1993,the area of sea water intrusion exceeded 3 km 2,and the maximum concentration of Cl - in groud water was 20 times that before sea water intrusion.Since the summer in 1993 the area of water intrusion in this region has become smaller.Another site of sea water intrusion was found along the southern coast at Qiaogangzhen in Beihai City in the late 1994. |
