Abstract
Compliance monitoring of bathing waters at La Grève de Lecq on the North coast of Jersey revealed a significant deterioration in water quality between 1992 and 1993, as indexed by presumptive coliform, presumptive Escherichia coli and streptococci concentrations. During the 1993 bathing season the beach failed to attain the compliance with the EC Guideline criteria for presumptive E. coli and streptococci. A bacteriological survey of the stream catchment draining to the beach revealed that: (i) concentrations of faecal indicator organisms were enhanced at high discharge after rainfall; and (ii) a captive water fowl population, which expanded between 1990 and 1993, was a potential source of faecal pollution. Strategies for catchment management are discussed.
对泽西岛北海岸La gr de Lecq浴场水域进行的合规监测显示，1992年至1993年期间，根据假定的大肠菌群、假定的大肠杆菌和链球菌浓度，水质明显恶化。在1993年的沐浴季节，该海滩未能达到欧共体指南关于推定大肠杆菌和链球菌的标准。一项对通往泳滩的集水区进行的细菌学调查显示:(i)在雨水过后的高排水量下，粪便指示生物的浓度会增加;(ii)圈养水禽种群在1990年至1993年期间扩大，是粪便污染的潜在来源。讨论了流域管理的策略。
