Oxidation of metal-sulfide minerals on waste surface leads to increased acidity, followed by elevated metal mobility of the mine spoil solution.
Based on FA/PCA, parent rock material, soil weathering, municipal and poultry waste, surface runoff from urban and agricultural land, automobile and laundry washing are the main source of inputs of contaminants into the feeding streams of Rawal Lake Reservoir.
Metals such as (Ni, Cu, Mn, Cr, Co, Fe, Pb, Cd, Zn, K, Mg and Li) and nutrients (SO4 2−, NO3 N) showed strong loadings indicated input from untreated discharge of municipal waste, surface runoff and solid waste into streams in pre-monsoon season.
Collection of Hg from soil gas also was made using Au traps with soda lime traps that were attached to a flux chamber placed directly on a soil or mine waste surface (Fig. 2), and the soil gas was drawn through the trap at 2 L/min for set times, generally 20 min at baseline sites and 5 min at mine sites.
Using different existing analytical methods several studies have already identified a variety of drugs in waste-, surface- and drinking water.
Legend: The weight of each contaminant that exceed the corresponding limit value for soil, sediments, inert wastes, surface and ground waters was calculated as the ratio between the found (Table 3) and reference values (Table 6).
These are important chemical parameters, because they may mitigate or enhance the corrosiveness of brines at the waste package surfaces.
Adsorption of water by deliquescent salt minerals found in aerosols and dusts that may be deposited on waste package surfaces during the construction and ventilation stages of a high-level radioactive waste repository at Yucca Mountain, NV, will be a primary source of brines that might lead to corrosion of the waste package surfaces.
NaCl, NaNO3, and KNO3 represent members of dust salt assemblages that are likely to deliquesce and form concentrated brines on high-level radioactive waste package surfaces in a repository environment at Yucca Mountain, NV.
