Many temporary and permanent reservoirs of water occur on or near coal-waste dumps in the Lower- and Upper Silesian Coal Basins (Poland). Little or nothing is known of the degree to which their water chemistry might reflect (i) reservoir type, i.e., whether permanent or temporary, (ii) level of coal-waste thermal activity, i.e., whether inactive or self-heating or burnt-out or (iii) region, i.e., whether the dumps are in Upper- or Lower Silesia. To provide some answers, concentrations of selected ions (NH₄⁺, HCO₃⁻, F⁻, Cl⁻, Br⁻, NO₂⁻, NO₃⁻, PO₄³⁻,SO₄²⁻) were determined by ion chromatography and of nineteen elements (Al, B, Ba, Ca, Cd, Cr, Cu, Fe, K, Li, Mg, Mn, Na, P, Pb, S, Si, Sr, Zn) by inductively coupled plasma mass spectrometry (ICP-MS). The data allow a number of the following observations. When permanent reservoirs are considered, there is a clear relationship between concentrations of ions and major and trace elements and dump thermal activity. The highest concentrations occur where the thermal activity is high as inorganic components are transformed into more water-soluble forms. As dump thermal activity shows a regional pattern, it follows also that elemental and ion concentrations in the dump waters show significant regional differences. In temporary reservoirs, concentrations of ions and major and trace elements are much lower and any correlations between components less significant than in the permanent reservoirs; these reservoirs exist for too short a time for any balance between coal waste- and water components to be established.

在西里西亚上下盆地（波兰）的废煤堆场附近或附近有许多临时和永久的水库。对其水化学反应的程度了解甚少或一无所知。（i）储层类型，即是永久性还是临时性；（ii）煤屑热活动水平，即是不活跃，自热还是燃烧-或（iii）地区，即垃圾场是在上西里西亚还是下西里西亚。为了提供一些答案，浓度选择的离子（NH ₄ ⁺，HCO ₃ ^-，F ^- ，氯^{- ，}溴^-，NO ₂ ^-，NO ₃ ^-，PO ₄ ^3-，SO ₄²⁻用离子色谱法测定19种元素（Al，B，Ba，Ca，Cd，Cr，Cu，Fe，K，Li，Mg，Mn，Na，P，Pb，S，Si，Sr，Zn）电感耦合等离子体质谱（ICP-MS）。数据允许进行以下一些观察。考虑永久性储层时，离子浓度与主要元素和痕量元素与堆放热活动之间存在明确的关系。当无机组分转化为水溶性形式时，在最高热活性时会出现最高浓度。由于垃圾场的热活动显示出区域格局，因此，垃圾场水中的元素和离子浓度也显示出明显的区域差异。在临时水库中 离子，主要和微量元素的浓度要低得多，并且各组分之间的任何相关性都比永久性储层低。这些储层的存在时间太短，以至于无法在煤废料和水成分之间建立任何平衡。
