摘要

20世纪70年代初,人们开始关注城市雨水中的污染物。几十年后,澳大利亚的调查还发现,城市雨水径流含有较高水平的沉积物和营养物质,以及重金属,这使雨水管理成为监管机构的首要任务。实施规划政策,以水敏感城市设计(WSUD)的形式将雨水管理纳入发展,国际上也称为低影响设计(LID)和可持续城市设计解决方案(SUD)。自其引入以来,用于验证其在实现减载目标(LRT)方面的成功的全面、大规模的现场研究一直受到限制。WSUD绩效的现场数据匮乏促使各组织开始了自己的针对当地的研究。关于监测程序设计的有限监管指导导致了各种方法和元数据记录。本研究综述整理了来自澳大利亚东海岸地理区域的77项澳大利亚研究的城市雨水数据。这篇综述中的原始数据集包括1993年至2021年间从地方议会、研究组织和水务部门收集的2836个事件和4536个个人结果。在采取任何形式的处理措施之前,审查检查了总悬浮固体(TSS)、总磷(TP)和总氮(TN)浓度,因为它们是当前雨水管理指南和标准的重点。用于为澳大利亚各地的雨水指南和水质建模提供信息的研讨会研究有显著差异(p<0.001),在这种情况下,大约是审查浓度的两倍。国际数据也平均高出20%以上。考虑到土地利用和集水区城市化日期的影响,集水区的地理位置对污染物浓度的影响最大(p<0.001)。根据本次审查的结果,澳大利亚现行规划法规中的一般负荷削减目标(以年度投入的百分比表示,如TSS减少80%、TN减少45%、TP减少45%),在实现接收水质目标方面可能是次优的,特别是考虑到当污染物以低浓度存在时难以去除。或者,达到或超过背景水质或生态和水文基准的基于地点的排放目标可能是实现环境目标的更合适的工具。

A Review of Pollutant Concentrations in Urban Stormwater Across Eastern Australia, After 20 Years
Concerns about pollutants in urban stormwater were initially raised in the early 1970s. Australian investigations decades later, also found urban stormwater runoff contained elevated levels of sediment and nutrients, as well as heavy metals, that brought stormwater management to the forefront for regulators. Planning policies were implemented to integrate stormwater management into development in the form of water sensitive urban design (WSUD), also known internationally as low-impact design (LID) and Sustainable Urban Design solutions (SUDs). Since their introduction, comprehensive broad scale field research to verify their success in achieving load reduction targets (LRTs), has been limited. Paucity of field data on the performance of WSUD has prompted organisations to initiate their own locally-specific studies. Limited regulatory guidance on design of monitoring programs has resulted in various methodologies and meta-data recording. This research review collates urban stormwater data from 77 Australian studies, from geographic regions of east coast Australia. The raw dataset in this review included 2,836 events and 4,536 individual results, collected between 1993 and 2021 from local councils, research organisations and water authorities. The review examined total suspended solids (TSS), total phosphorus (TP) and total nitrogen (TN) concentrations, prior to any form of treatment measures as they are the focus of current guidelines and standards for stormwater management. Seminal research, used to inform stormwater guidelines and water quality modelling across Australia, is significantly different (p < 0.001), in this case approximately double the reviewed concentrations. International data is also >20% higher, on average. Geographic location of catchments had the greatest influence on pollutant concentrations, after accounting for the effects of land use and catchment urbanisation date (p < 0.001). Based on the findings of this review, generic load reduction targets (expressed as a percentage of annual inputs, e.g. 80% TSS reduction, 45% TN, 45% TP) typical in current Australian planning regulations, may be sub-optimal in achieving receiving water quality goals, particularly given the difficulty of removing pollutants when present in low concentrations. Alternately, place-based discharge targets which meet, or exceed, background water quality, or ecological and hydrological benchmarks may be a more appropriate tool to achieve environmental objectives.
