ABSTRACT: Regulatory water quality monitoring has evolved to the point where it is a rather complex system encompassing many monitoring purposes and involving many monitoring activities. Lack of a system's perspective of regulatory monitoring hinders the development of effective and efficient monitoring programs to support water quality management. In this paper the regulatory water quality monitoring system is examined in a total systems context. The purposes of regulatory monitoring are reviewed and categorized according to their legal evolution. The activities of regulatory monitoring are categorized and organized into a system which follows the flow of information through the monitoring program. The monitoring purposes and activities are combined to form a monitoring system matrix - a framework within which the total regulatory water quality monitoring system is defined. The matrix, by defining the regulatory monitoring system and clarifying many interactions within the system, provides a basis upon which a more thorough approach to managing, evaluating, and eventually optimizing regulatory monitoring can be developed. 相似文献

Budget changes, whether positive or negative, in water quality management agencies often mean a change in resources available for water quality monitoring. Many state agencies are currently facing monitoring budget cuts and, as a result, are reevaluating their monitoring programs. Such evaluations make use of a number of information sources, not the least of which are monitoring activities in other states. This article reports results of a survey of all fifty state water quality monitoring programs. Twenty questions were asked in the general areas of fixed-station monitoring, special studies, and biological monitoring. Each state was contacted by telephone at least twice during the survey. Fixed-station monitoring is conducted by 48 of 50 states. An average of 75 stations per state are sampled, generally on a monthly basis. There is a large variation in the way data are analyzed by the states; water quality indices and plots of concentration or loading over time are the most common methods. All but three states conduct special studies, but only seven repeat the studies on a regular basis. Special studies are generally problem specific as opposed to basin oriented. Biological monitoring is performed by 33 states; however, this is an area in which budget cuts are having a noticeable impact. In some cases, biological monitoring is being completely eliminated or suspended. Macroinvertebrate sampling is performed quarterly to biannualiy by 50% of the states; 75% of the states that sample macroinvertebrates do so annually. Periphyton sampling is performed by 33% of the states. Over 50% of the states are in the process of revising, or have revised, their monitoring program during the past five years. However, only four states had a detailed rationale and operating procedure for the entire monitoring system. Results of the survey are, therefore, averages of existing monitoring programs. Average results do not necessarily represent ideal situations, but do give an indication of how states are coping with their monitoring responsibilities. 相似文献

The recognition of complexity and uncertainty in natural resource management has lead to the development of a wealth of conceptual frameworks aimed at integrated assessment and complex systems monitoring. Relatively less attention has however been given to methodological approaches that might facilitate learning as part of the monitoring process. This paper reviews the monitoring literature relevant to adaptive co-management, with a focus on the synergies between existing monitoring frameworks, collaborative monitoring approaches and social learning. The paper discusses the role of monitoring in environmental management in general, and the challenges posed by scale and complexity when monitoring in adaptive co-management. Existing conceptual frameworks for monitoring relevant to adaptive co-management are reviewed, as are lessons from experiences with collaborative monitoring. The paper concludes by offering a methodological approach to monitoring that actively seeks to engender reflexive learning as a means to deal with uncertainty in natural resource management. 相似文献

固定源烟气对比监测是保证自动监测数据质量的重要手段。但是,有效性审核比对监测过程中存在烟气排放连续监测系统安装不规范、手工监测抗干扰能力较差、烟气预处理效果不稳定及监测点位差异影响监测结果比对等问题。在此基础上,提出了严格规范环境监测点位的布置,针对不同的污染源确定适合的监测技术方法,研发完善的烟气预处理设施以及建立健全的自动监测质量保证体系等解决问题的对策。 相似文献

自动监测是环境监测的一个重要组成部分。桐乡市从2004年初开始着手建设环境质量自动监测系统,到目前为止,已建成两个水质自动监测站和一个空气自动监测站。投入使用后,积累了大量有效的监测数据,显示了人工监测不可比拟的优势,大大提高了环境保护管理部门的科学决策水平。 相似文献

山东省探索开展了空气质量监测"转让-经营"模式改革,在体制上科学划分监测事权,实行"谁考核、谁监测",省级环保部门负责17个设区城市环境质量的监督监测,污染源监督监测下放到市、县级环保部门;在机制上实行政府购买服务,对全省空气质量自动监测站实行"监测设备有偿转让,专业队伍运营维护,专业机构移动比对,环保部门质控考核,政府购买合格数据"的"转让-经营"模式。通过改革,监测数据质量和监测公信力得到进一步提高,有效避免了可能的行政干预,降低了监测成本,引导了环保服务业的发展,可以为其他省、市贯彻落实生态环境监测体制改革和地方监测事权上收工作提供一些参考。 相似文献
