To make dredged materials compatible with an intended beneficial use, it is often necessary to first treat the materials to reduce the concentrations, toxicity, and/or mobility of contaminants. This review evaluates existing and emerging treatment technologies that support beneficial use of dredged materials and identifies factors that influence their success and limitations. This review focuses on recent publications on ex situ treatment technologies, including solidification and stabilization technologies, extraction treatments, and bioremediation. Most studies on the efficacy of treatment technologies have been conducted at the laboratory- or pilot-scale, and the heterogeneity of contaminant concentrations and the physical characteristics of dredged materials strongly influence the effectiveness and efficiency of treatments. Many recent studies describe the combined use of two or more treatments. One outcome of this review is a database of projects in which dredged materials were treated to facilitate beneficial use of contaminated sediment. Few sources reported details on the full life cycle of projects, costs and benefits, timelines and durations, contaminant concentrations in dredged and treated materials, regulatory thresholds and acceptance, or the basis for selecting beneficial use applications. To address this data gap, the creation of a data platform to share information and promote knowledge and data sharing of the salient details is recommended through partnerships with permitting agencies and practitioners.</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143803062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The circular economy's principle of reuse offers a potential solution, but more research is needed to facilitate this transition. The informal sector plays a key role in waste reuse, yet its integration with formal regulatory framework and waste management systems remains challenging. A study in Lebanon, using semi-structured interviews with stakeholders, explored the informal sector's role in waste reuse. The findings reveal that while the reuse and repair market has grown due to the economic crisis, it remains underdeveloped. Informal workers create challenges by hindering the efficiency of formal waste management systems and undermining the economic sustainability of recycling projects. Their unregulated activities can lead to operational disruptions, reduced material value, and increased public health and environmental costs. The informal sector operates with little oversight, and the system's deficiencies-legal, technical, and economic-exacerbate these issues, including the absence of an effective cost-recovery mechanism. Formalizing or integrating the informal sector is a complex process that involves not only waste management issues but also political and regional challenges. The research suggests that regulating the waste management sector is the best approach to address these challenges, helping transition informal workers into a formalized system.

Using APCOAT, we modeled potential co-occurrence between atrazine applied to corn and aquatic habitats across the continental U.S. by developing habitat models for 375 species in flowing waters and 130 species in static waters. The species habitat models showed high predictive power (70-99% accuracy, median 98%) while maintaining parsimony (median 9 environmental variables). Analysis of both local watershed and upstream pesticide transport revealed that 70% of habitat-pesticide combinations had <5% co-occurrence probability, 25% showed 5-10%, and 5% exceeded 10%. The probabilistic approach provides more refined estimates of both species habitat extent and pesticide usage patterns compared to deterministic methods.

Sampling was carried out across two distinct climatic seasons (wet and dry) in 2018, spanning seven weeks in each season (April-June and October-November). The assessment employed multi-indicators, including biological (fungi and bacteria), chemical (particulate matter and carbonyl compounds), and physical parameters (noise and thermal comfort). Air quality indicators showed the following ranges: PM10 levels varied between 1.12 and 55.85 μg.m-³, PM2.5 levels ranged from 0.69 to 34.43 μg.m-³, and carbonyl compounds were observed at concentrations between 0.85 and 816.37 μg.m-³. Biological indicators included fungi counts ranging from 61.0 to 735 CFUs.m-³ and bacterial counts between 142.0 and 2381.5 CFUs.m-³. Physical indicators measured noise levels at 59.87 to 66.81 dBA and thermal comfort values between 25.31 and 27.18 DI. Higher concentrations of atmospheric pollution were observed during the wet season, while thermal comfort was better during the dry season. Noise levels remained relatively constant across seasons. Notably, formaldehyde concentrations at most sampling points posed a high cancer risk, exceeding limits set by regulatory agencies. Three points also presented significant health risks due to particulate matter (PM) exposure. The evaluation method combined direct measurements with multivariate statistical techniques to calculate an Environmental Quality Index (EQI), classifying sites as \"excellent,\" \"good,\" or \"poor.\" The findings highlight the influence of factors such as vehicular traffic, vegetation coverage, and building density on environmental quality.

The US Environmental Protection Agency (USEPA) and Washington Department of Ecology (Ecology) were interested in whether the performance of ENR with AC would enhance effectiveness of ENR in the Lower Duwamish Waterway (LDW), a tidally influenced, salt-wedge estuary. In 2014, USEPA and Ecology directed the Lower Duwamish Waterway Group (LDWG) to evaluate the potential effectiveness of using AC (Coconut Fine Mesh Activated Carbon graded 200 to 1,000 micrometers) with ENR (referred to herein as ENR+AC) to remediate polychlorinated biphenyls (PCBs) in aquatic sediment in the LDW. This three-year pilot study established three one- acre areas within the LDW representing different site conditions (intertidal conditions, an area prone to scour, and subtidal conditions) where ENR+AC and ENR would be compared. The target ENR and ENR+AC thickness was 15 to 30 cm with 4% AC in the ENR+AC plots; actual thicknesses across all plots were 15 to 46 cm, with a mean depth of material across plots that ranged from 24 to 35 cm. Over the three-year study period, the ENR and ENR+AC placements were relatively stable, and AC remained stable within the ENR+AC plots. While final ENR applications were somewhat thicker than expected, benthic community results demonstrated substantial biological activity during the study, including organisms that burrow deeper than the ENR layer depth. Both treatments performed similarly at plots where the performance could be most accurately assessed (ie, at the Intertidal and Subtidal Plots). For the Intertidal Plot, the average (±SD) Year 3 freely dissolved (Cfree) total PCB concentration in the ENR subplot was 1.6 ± 0.26 ng/L, compared to 0.78 ± 0.19 ng/L in the ENR+AC subplot; the difference in Year 3 Cfree concentrations, while small, was statistically significant (p = 0.011) and reflected 95% and 97% decreases from average baseline Cfree concentrations, respectively. The Subtidal Plot had a 96% decrease from baseline Cfree PCBs in Year 3 in the ENR+AC subplot compared to an 89% decrease in the ENR-only subplot. Average Year-3 Subtidal Plot Cfree concentrations were 4.3 ± 1.1 ng/L and 3.8 ± 0.42 ng/L, respectively; the difference between the subplot concentrations in Year 3 was not statistically significant (p = 0.588), suggesting that he larger decrease seen in the ENR+AC subplot was influenced in part by a higher baseline Cfree PCB concentration in the ENR+AC subplot (108 ng/L) compared to the ENR subplot (36 ng/L). In the Scour Plot, low baseline Cfree PCB concentrations in the ENR (1.5 ng/L) and ENR+AC (11 ng/L) subplots made it difficult to statistically compare the Scour Plot performances.

A publication by Liess and co-authors in 2021 concluded that 83% of agricultural streams included in the monitoring study were in an unacceptable ecological condition. This conclusion was based on a comparison of benthic macroinvertebrate (BMI) communities between reference and agricultural sites. The authors observed a decline in vulnerable BMI species, which they attributed to agricultural nonpoint source pollution by pesticides. We conducted an extensive re-analysis of the raw data and found that many of the study results were not reproducible because of a lack of detailed reporting of data processing methods. Other data processing steps and decisions by the authors lacked supporting rationales. Further, we found that the indicators of pesticide pressure for some stream sections were derived from samples taken after BMI communities had been sampled and are therefore not indicative of a causal relationship between pesticide pressure and community status. We recommend that the original dataset be filtered to include only stream sections with complete and temporally consistent data for both pesticide and macroinvertebrate sampling. This approach would enhance the transparency of the analysis and enable the scientific community to better assess the evidence supporting the authors' conclusions regarding the dominant stressors affecting BMI community structure in German lowland streams.
