Abstract

This work presents an assessment of seasonal changes and a chemometric study ofsurface water parameters on reclaimed and reforested areas of a former sulphur minewhere the mineral was extracted using the Frasch method. Water samples werecollected four‐times at 15‐monitored sampling points located on streams and ponds.Base chemical parameters of water (such as pH, EC, ion concentrations, and total P, S,and Al) were determined in laboratory conditions. A chemometric study with theapplication of the principal component analysis PCA method using the EM (expecta-tion‐maximisation algorithm) procedure was employed to determine seasonal changesand similarities or dissimilarities between the water samples. The obtained resultsindicate an overall low seasonal and spatial variability of the investigated surfacewater parameters: mean pH for seasons from 6.2 to 6.7, EC 1,819–1,990μScm−1,S 380.7–484.2 mg L−1. However, the occurrence of hot spots was found (in threeout of 15 monitoring points), which typically displayed very low pH (below 4.0), highEC (above 2,000μScm−1) and sulphur content (above 400 mg L−1), or a high propor-tion of calcium ions associated with the neutralisation of sulphurous soils. Traceelements occur in very low concentrations because most of the sampling pointsdisplayed high pH. The research was carried out in a unique location where high‐sulphur concentration in soils was not correlated with acidification but rather withalkalisation (hotspots). This phenomenon was related to the specificity of reclamationwhere post‐flotation lime were used.
