Telemetric System for Hydrology and Water Quality Monitoring in Watersheds of Northern New Mexico, Usa

This study utilized telemetric systems to sample microbes and pathogens in forest, burned forest, rangeland, and urban watersheds to assess surface water quality in northern New Mexico. Four sites included remote mountainous watersheds, prairie rangelands, and a small urban area. The telemetric system was linked to dataloggers with automated event monitoring equipment to monitor discharge, turbidity, electrical conductivity, water temperature, and rainfall during base flow and storm events. Site data stored in dataloggers was uploaded to one of three types of telemetry: 1) radio in rangeland and urban settings; 2) a conventional phone/modem system with a modem positioned at the urban/forest interface; and 3) a satellite system used in a remote mountainous burned forest watershed. The major variables affecting selection of each system were site access, distance, technology, and cost. The systems were compared based on operation and cost. Utilization of telecommunications systems in this varied geographic area facilitated the gathering of hydrologic and water quality data on a timely basis.

天津滨海某化工园区废水预处理去毒技术研究

化工产业是天津滨海新区重要的支柱产业,该行业废水因污染种类复杂,具有高盐、高毒、难降解等特点,是滨海新区污染物控制的主要威胁。通过对滨海某化工区实际废水进行几种主流预处理技术及其组合工艺的研究,明晰了其在实验条件下各自的特点,验证了其实际处理效果,进一步掌握了其反应过程中的特性,为研究后续的示范工程应用及大规模推广打下基础。实验表明,制药废水经内电解处理后毒性削减率最高可达到46%,对化学合成废水有较好的去毒效果,该技术可有效地提高制药废水的可生化性;光催化氧化对苯胺和氯苯的最佳降解条件分别是15 g/L TiO(23 h)及17.5 g/L TiO2;负载型纳米铁和纳米四氧化三铁催化剂分别适合极酸和中性、偏碱性条件,催化效率高,COD去除效果好。     

2018年春节北京市噪声污染分析

利用北京市87个噪声自动监测站点监测数据,分析2018年除夕夜(2月15日18：00—2月16日2：00)全市噪声排放水平。通过比较2013—2018年除夕夜噪声排放强度,结合北京市细颗粒物浓度变化分析,表明2018年除夕夜北京市噪声污染排放显著降低,2013—2018年噪声污染排放存在时空分布特征,除夕夜细颗粒物污染变化与噪声污染变化趋势较为吻合,作为主要污染源的烟花爆竹燃放在受到政策的限制后,除夕夜北京市声环境和空气环境同比大幅改善。     

Environmental Monitoring Of Remedial Dredging At The New Bedford Harbor, Ma, Superfund Site

New Bedford Harbor (NBH), MA, is a Superfund site because of high polychlorinated biphenyl (PCB) concentrations in the sediment. From April 1994 to September 1995, a remedial dredging operation (termed the “Hot Spot”) removed the most contaminated sediments (PCB concentrations greater than 4000μg/g) from the upper harbor. During remediation, a monitoring program assessed the potential environmental impacts to NBH and adjacent Buzzards Bay. The monitoring program was developed with input from federal, state, and local authorities. Site-specific decision criteria were established to assess net PCB transport, water column toxicity, and PCB bioaccumulation in blue and ribbed mussels (Mytilus edulis and Geukensia demissa, respectively). The remediation was completed without exceeding PCB net transport or acute toxicity effects specified in the decision criteria. In addition, PCB bioaccumulation in mussels during this time period was not significantly greater than pre- or post-operational measurements. The results indicated that approximately 14000 cubic yards of highly PCB contaminated sediment were permanently removed with minimal environmental effects. The lessons learned during this operation, as well as previous pilot studies at the site, will be used to make full-scale remedial efforts in NBH more efficient and environmentally protective.

Rehabilitation and Flood Management Planning in a Steep,Boulder-Bedded Stream

This study demonstrates the integration of rehabilitation and flood management planning in a steep, boulder-bedded stream in a coastal urban catchment on the South Island of New Zealand. The Water of Leith, the primary stream flowing through the city of Dunedin, is used as a case study. The catchment is steep, with a short time of concentration and rapid hydrologic response, and the lower stream reaches are highly channelized with floodplain encroachment, a high potential for debris flows, significant flood risks, and severely degraded aquatic habitat. Because the objectives for rehabilitation and flood management in urban catchments are often conflicting, a number of types of analyses at both the catchment and the reach scales and careful planning with stakeholder consultation were needed for successful rehabilitation efforts. This included modeling and analysis of catchment hydrology, fluvial geomorphologic assessment, analysis of water quality and aquatic ecology, hydraulic modeling and flood risk evaluation, detailed feasibility studies, and preliminary design to optimize multiple rehabilitation and flood management objectives. The study showed that all of these analyses were needed for integrated rehabilitation and flood management and that some incremental improvements in stream ecological health, aesthetics, and public recreational opportunities could be achieved in this challenging environment. These methods should be considered in a range of types of stream rehabilitation projects.

Hazard vulnerability assessment: How well does nature follow our rules?

Vulnerability is a central construct in environmental risk assessment, and a variety of methods have been introduced to facilitate its expression as a planning and decision-making device. The contrasting interpretations generated by these methods of modelling produce dramatic differences in spatial representation that contribute to uncertainty, and no clear connection has been established between vulnerability and the actual consequences resulting from a nature hazard event. In this study, geographic information system-based vulnerability modelling is evaluated, and the association between modelled-produced expressions and the aftermath impact of a natural hazard event on the human landscape is examined. Employing hurricane aftermath data from the 2005 Hurricane Katrina event in New Orleans, Louisiana, this study presents a comparative analysis that can assist in the validation of vulnerability assessment methods and identify limitations in current modelling strategies. The results of this analysis demonstrate that the methods employed to model vulnerability do not necessarily capture the actual consequence of a natural hazard event and suggest that place-specific factors should play a more significant role when assessing hazard vulnerability.
