Comparison of sediment-related analytical data by correlation analyses between each magnetic parameter and individual particle size classes (i.e. sand, silt and clay), and more discrete intervals within classes (e.g. fine sand or medium silt) are reported. XLF, XARM and SIRM parameters reveal few significant (p < .05; n = 60), weak (rs = .443), associations with clay content. Specific areas of historic anthropogenic activity are investigated and reveal improved correlations with )XLF vs. clay (r = .739, p < .001; n = 60), silt (r = -.612, p < .001; n = 60), and discrete fractions of sediment (r = .700-.868; p < .001). Comparison of mineral magnetic concentration and geochemistry are also reported with moderate to strong relationships between XLF, XARM, Fe, Pb and Co. Contrary to earlier research findings, the results for the Birmingham Canal Navigations Main Line indicate that magnetic measurements cannot always provide a predictable particle size proxy and it is only certain environments and/or specific settings that are appropriate for granulometric normalization by this technique.

Different types of polluted aqueous effluents and sediments may be produced, which contain relatively high levels of heavy metals. During the 1990s, the large-scale development of constructed wetlands around the world drew much attention from public and environmental groups. The present study looks at the use of an integrated remediation system using zeolites for the treatment of wastewater and sediments. Zeolites have been widely studied in the past 10 years due to their attractive properties such as molecular-sieving, high cation exchange capacities, and their affinity for heavy metals. Coal industry by-products-based zeolites (faujasite type) have been tested as an effective and low-cost novel alternative for wastewater treatment, particularly their removing of heavy metals. On the other hand, a preliminary laboratory-scale experiment was conducted on the use of natural zeolites (cl...

Experimental work revealed promising results, which could be replicated on a bigger scale. Although this has been developed for canal sediments, the remediation strategy can be adapted to different waterways such as rivers. The development of the proposed remediation system in a specific experimental site as the major part of an innovation park can provide great benefits to a population living near contaminated effluents. It provides not only opportunities for the mitigation of environmental impact, improving water quality and landscape amenity, but also allows for several recreational opportunities.
