Development of high performance and efficient coating repair systems for offshore tropical marine environment
… gap is probably due to high relative humidity, salt contamination and limitations on the use of abrasive blast cleaning. Thus, this research aims to deepen the understanding of surface preparation parameters that affect organic coating performance. Carbon steel samples were subjected to a …

Electrical resistivity and ground-penetrating radar as tools to characterize groundwater surface water interaction at Mirror Lake, NH
… water interaction, as well as for imaging road salt contamination. In-situ measurements of seepage coincident with resistivity surveys suggested a relationship between resistivity values and seepage rates. Specifically, we observed that seepage rates were low (averaging-20 cm/day) at Mirror Lake …

Saltwater spill site assessment and remediation in Northern Alberta
… environmental site assessment process for salt contamination resulting from pipeline failures in the boreal forest of Alberta. A complex saltwater spill site is used as a case study to determine the effects of various parameters of interest, including electrical conductivity and sodium …

Road Salt Runoff - Impact on Macroinvertebrates and Water Quality
… trophic level predators in freshwater food webs. Salt contamination due to road de-icing can often produce a dense saline layer just above the sediment–water interface potentially exposing benthic macroinvertebrates to high salt concentrations. Reported impacts on salinity increase on …

Evaluación de alternativas de gestión del regadío tradicional para la reducción del impacto agroambiental
… pollutants exported and, in this way, values of salt contamination index (70% lower) and nitrate contamination index (24% lower). Although changes in irrigation management implemented in this irrigation land caused a negative impact on water quality and agricultural soils, simple alternatives in …

ASSESSING THE ROLE OF GEOLOGIC SETTING ON THE HYDROLOGY AND GROUND WATER GEOCHEMISTRY OF FENS IN THE GLACIATED MIDWESTERN UNITED STATES
… to Na+ and Cl-, which has been linked to road salt contamination at two of the study sites. This hydrogeochemical study also reveals that fens (slope wetlands) within this particular geologic setting of central Indiana show strong geochemical similarities to fens located throughout the …

Risk analysis and mitigation of seawater intrusion for the Gaza strip coastal aquifer under climate induced changes
… or mixing zone) between these regimes, causing salt contamination of freshwater aquifers. In the Mediterranean area, seawater intrusion (SWI) has sometimes become a major threat to coastal area freshwater resources, mainly due to lack of appropriate groundwater resources management. Current …
