EC Bathing Water monitoring (under Directive 76/160/EC) around the Northern Ireland coast

Early in 1987 the Department of the Environment (NI) identified 16 Northern Ireland marine bathing waters to be monitored in respect of the EC Directive (76/160/EEC). In 1991 the monitoring was extended to include an additional 9 non-identified bathing waters. A key station at each of these bathing waters is sampled on at least 20 occasions from May to September. In addition multi-point sampling of each bathing water is undertaken on two occasions during the season to assess the overall bacteriological quality of the bathing water. The microbiological parameters measured are as follows: 1. total and faecal coliforms are determined for all samples 2. faecal streptococci are determined for all samples 3. salmonella spp are measured twice for the key stations Values of pH are determined using a Cornig-Eel model 109 pH meter. Transparency measurements are performed using a 200mm diameter Secchi disc. Visual notes of colour, the presence of mineral oils, surface-active substances and phenolic odour are also recorded.

早在1987年初，英国环境部（北爱尔兰）便已确定对16处北爱尔兰海滨浴场进行监测，以符合欧洲共同体指令（76/160/EEC）。至1991年，监测范围进一步扩大，新增9处未标识的浴场。在这些浴场中，每个关键监测点均于5月至9月期间至少进行20次采样。此外，在每个浴场季节期间，还进行两次多点采样，以评估浴场的整体微生物质量。所测量的微生物学参数包括：1. 对所有样本进行总大肠菌群和粪便大肠菌群检测；2. 对所有样本进行粪便链球菌检测；3. 对关键监测点进行两次沙门氏菌属检测。pH值测定采用Cornig-Eel型号109 pH计。透明度测量使用直径为200毫米的塞奇迪斯。同时，对颜色、矿物油、表面活性物质和酚类气味进行视觉记录。
