An increase in groundwater chloride concentrations was first reported 20 years ago in Finland. This discovery coincided with a sharp rise in the rate of road-salt application – the annual amount of NaCl consumed had increased from 50 t a −1 in the late s to t a −1 10 years later. To reverse these trends, research and development projects aimed at the reduced application of sodium Missing: dustbinding--risk.

Instead, these compounds are transported with melt water, where they either percolate to aquifers belowground, or run directly into surface water bodies. In surface water systems, chloride (Cl{) is chronically toxic to aquatic life at mg L 1 and acutely toxic at mg L 1 (US EPA, ). While. The effects of human activities on water resources, whether ground water or surface water, are complex (Winter and others, ). The increased proportion of the county devoted to urban and residential land uses is accompanied by more wells that extract water, more impervious surfaces that block or redirect recharge, and more storm drains that divert precipitation into streams instead of g: dustbinding--risk.

Potassium formate was used to deice a stretch of a highway in Finland. The fate of the formate was examined by monitoring the groundwater chemistry in the underlying aquifer of which a conceptual model was constructed. In addition, we determined.

A comparison was made of the ability of three different methods to describe the deposition and distribution of chloride from deicing salt in the roadside environment along a highway: direct sampling of airborne deposition (including snow ploughing) in containers; soil sampling and analysis of chloride content in the topsoil; and direct current resistivity measurements.

Each method showed a. Olofsson, B., and Sandström, S, In Deicing and dustbinding — risk to aquifers, Nystén, T. and Suokko, T., Eds., NHP Report No 43, pp 75–Missing: dustbinding--risk.

The waste generated by aircraft deicing operations represents a threat to the environment arising from the high biological oxygen demand of propylene and ethylene glycols and the toxicity associated. The de-icing salt most frequently used is NaCl, which has been documented to promote metal leaching from roadside soils by a range of different processes.

If the conditions are favourable, Cl and metals form water-soluble complexes, and consequently reduce the extent of metal retention (Doner,Boekhold et al.,Lumsdon et al., ).

The salt lens, in the upper part of the aquifer beneath the highway, has developed to a thickness of 8 m and a width of m and constitutes a linear source of salts for the aquifer.
