Human-dominated land uses can increase transport of major ions in streams due to the combination human-accelerated weathering and anthropogenic salts. Calcium, magnesium, sodium, alkalinity, hardness significantly increased drinking water supply for Baltimore, Maryland over almost 50 years (p<0.05) coinciding with regional urbanization. Across a nearby use gradient at Baltimore Long-Term Ecological Research (LTER) site, there were significant increases concentrations dissolved inorganic...
Abstract Freshwater salinization is an emerging global problem impacting safe drinking water, ecosystem health and biodiversity, infrastructure corrosion, food production. originates from diverse anthropogenic geologic sources including road salts, human-accelerated weathering, sewage, urban construction, fertilizer, mine drainage, resource extraction, water softeners, saltwater intrusion, evaporative concentration of ions due to hydrologic alterations climate change. The complex...
Widespread changes in water temperatures, salinity, alkalinity and pH have been documented inland waters North America, which influence ion exchange, weathering rates, chemical solubility contaminant toxicity. Increasing major concentrations from pollution, human-accelerated saltwater intrusion contribute to multiple ecological stressors such as changing ionic strength mobilization of mixtures resulting the freshwater salinization syndrome (FSS). Here, we explore novel combinations elements,...
Abstract Factors driving freshwater salinization syndrome (FSS) influence the severity of impacts and chances for recovery. We hypothesize that spread FSS across ecosystems is a function interactions among five state factors: human activities , geology flowpaths climate time . (1) Human drive pulsed or chronic inputs salt ions mobilization chemical contaminants. (2) Geology drives rates erosion, weathering, ion exchange, acidification‐alkalinization. (3) Flowpaths contaminant along...
Freshwater salinization syndrome (FSS) refers to the suite of interactive effects salt ions on degradation physical, biological, and social systems. Best management practices (BMPs), which are methods effectively reduce runoff nonpoint source pollution (stormwater, nutrients, sediments), do not typically consider pollution. We investigate impacts FSS mobilization salts, metals in urban streams stormwater BMPs by analyzing original data concentrations fluxes from 7 watersheds Mid-Atlantic USA...
