“…Dredge materials from the mid‐Atlantic United States have been successfully combined with other residuals to produce manufactured soils for wider applications for brownfield redevelopment, gardening, and landscaping applications (Lee, 2001). Similar findings and potential applications have been reported for Ireland (Sheehan and Harrington, 2012; Sheehan et al, 2010). However, adverse effects of metal sulfide oxidation from upland placed dredge materials in Belgium have also been noted by Cappuyns et al (2006), along with similar reports of acid sulfate soil formation in a range of dredge spoil materials placed in the mid‐Atlantic United States (Fanning and Fanning, 1989; Demas et al, 2004).…”

Beneficial Use of Dredge Materials for Soil Reconstruction and Development of Dredge Screening Protocols

Upland placement of dredge sediments has the potential to provide beneficial reuse of suitable sediments for agricultural uses or urban soil reconstruction. However, the use of many dredge materials is limited by contaminants, and most established screening protocols focus on limiting major contaminants such as heavy metals and polycyclic aromatic hydrocarbons and generally ignore fundamental agronomic parameters. Since 2001, we have placed over 450,000 m of Potomac River fresh water dredge materials and 250,000 m of saline materials from various locations into monitored confined upland facilities in Charles City, VA, and documented their conversion to agricultural uses. Groundwater and soil quality monitoring has indicated no adverse effects from material placement and outstanding agricultural productivity for the freshwater materials. Once placed, saline materials rapidly leach and ripen with quick declines in pH, electrical conductivity, and sodicity, but potentials for local groundwater impacts must be considered. Our experience to date indicates that the most important primary screening parameter is acid-base accounting (potential acidity or lime demand), which should become a mandatory analytical requirement. Our second level of acceptance screening is based on a combination of federal and state residual waste and soil screening standards and basic agronomic principles. High silt+clay and total organic C may also limit rapid use of many dredge materials due to extended dewatering times and physical limitations. This dredge material screening system separates potential upland placement candidates into three soil quality management categories (unsuitable, suitable, and clean fill) with differing monitoring requirements. Similar use of these sediments in urban soil reconstruction is also recommended.

“…Primary responsibility for dredge sediment management in Ireland lies with the main commercial ports who have an on-going maintenance dredge requirement. Dredged sediment management issues, practice and trends in Ireland have previously been presented by, for example, Harrington et al (2004), Sheehan & Harrington (2012) and Harrington & Smith (2013).…”

This paper presents and applies an economic model developed for the management of dredged marine sediments. The model predicts direct project costs and direct, indirect and induced economic impacts. The model is applied to analyse the economic aspect of the specific potential beneficial use of dredged sediment for land reclamation in an Irish context. The model results show the potential economic benefits to land reclamation of using dredged sediment including its value as a potential substitute for quarry based material and as an alternative to traditional offshore dredged sediment disposal, where appropriate. Analysis of other sediment management approaches including wetland creation, is also presented with the results for wetland creation indicating its potential, where appropriate, as a valuable alternative to offshore disposal. Indicative economic benefits are predicted by the model for the different dredge sediment management approaches analysed.

“…The complexity of these problems was highlighted in the European Sediment Research Network EU-funded project, in which "dredging" and "dredging disposal" were the second and third of the top ten environmental issues at ports [21]. Contemporary ports should operate in a more environmentally friendly manner due to the increasing awareness and concerns of their stakeholders [22] and regulations and directives [23,24]. This demand is greater for leisure harbors (marinas), in which the Blue Flag award implies the achievement of significant environmental standards.…”

Engineering infrastructures require regular maintenance and/or repair activities that have important social, environmental, and economic impacts. Despite their growing importance, few studies have focused on fully integrated analyses. This work presents a general methodological approach to design databases of engineering maintenance activities for their assessment. This methodology was applied to the case of dredging projects in the ports managed by the Andalusian Regional Government (Spain). The resulting database contains 87 fields of information obtained from the analysis of 70 activities performed between 1993 and 2015. This database is free, public, and available to the scientific community, and it was implemented in PostgreSQL using the PostGIS extension for spatial data; therefore, it can be integrated in a GIS. The assessment of deviations from the initial projects and the comparison between locations enhanced our methodology, which represents a valuable tool not only for scientists and managers to improve the decision-making process when planning future strategies, but also to evaluate the environmental impacts.
