Technical guidelines for monitoring surface water environmental quality and centralized drinking watTechnical guidelines for monitoring surface water environmental quality and centralized drinking water sources in earthquake stricken areas (Interim) Chapter I General Provisions Article 1 the monitoring surface of centralized drinking water sources in key areas of the earthquake stricken area and the upper and lower reaches of the important cities. Relevant provinces and cities to add visual monitoring of local conditions. Second monitoring frequency once a day, according to the progress of post disaster reconstruction appropriate adjustments. Third in order to ensure the timeliness of water quality monitoring, priority to the use of rapid monitoring methods and equipment, on-site rapid investigation and laboratory analysis of organic combination. Analytical methods may refer to schedule. Fourth closely monitoring the various potential pollution sources, focus on monitoring the pollutant with toxic effects on the human body, according to the investigation of the production situation, pollution source of local enterprises with the latest information, determine the characteristics of pollution substances. Article fifth shall establish a water source protection mark at a significant location and location, and notify the relevant departments and units of the protection of water sources regulations. Chapter second water quality routine monitoring requirements Sixth establish an important monitoring section and drinking water source timing inspection system, no special circumstances no less than 1 times a day. The change of water quality indicators pH, conductivity and permanganate index (conditional can include TOC) to focus on monitoring the conditions of the monitoring station, as the case may be increased ammonia, phenols and other routine monitoring item. Seventh on-site inspections should pay attention to observe and record water color, odor and floating objects and other sensory indicators to determine whether the water was significantly polluted. Eighth daily monitoring fecal coliform, total number of bacteria (kit can be used, such as rapid test method), abnormal should be increased when routine pathogen monitoring (kit can be used and other rapid test methods). Ninth conditional monitoring station daily biological acute toxicity monitoring (can use luminescent bacteria method), for the comprehensive judgment of water quality safety. Tenth monitoring the conditions of the daily monitoring of the human toxic and harmful pollutants (heavy metals and toxic organic pollutants), attention to the use of chemicals in disaster relief, specific pollutants can be determined according to the results of the investigation of local pollution sources. Eleventh when the confirmation of water is abnormal, the retained sample analysis standby at the same time, should immediately check, if sustained abnormal situation, immediately launched the emergency monitoring of water quality, and the surrounding environment to conduct inspection, investigation as soon as possible sources of pollution and pollution, the timely report to the higher authorities, and inform the relevant departments. Automatic monitoring in the third chapter Twelfth as soon as possible to restore the original site automatic monitoring and testing project, for abnormal water area, can be based on the original test on the project according to the local conditions appropriate to increase other automatic monitoring project. Thirteenth in important water sources according to local conditions may consider increased online toxicity monitoring. The fourth chapter emergency environmental emergency monitoring Fourteenth pay close attention to the post disaster environmental safety hazards constitute facilities, such as chemical plants, gas stations, pesticides centralized storage places, victims concentrated resettlement area. Fifteenth in case of environmental emergencies, should be the first time arrived at the scene of sample collection, storage and monitoring, the investigation of pollution sources and characteristics of pollution, promptly notify the relevant departments, and immediately launched the emergency monitoring work.
