Abstract

The article focuses on the results of water parameters (COD, pH, electrical conductivity) and the contents of major ions (Ca²⁺, Mg²⁺, Na⁺, K⁺, \({\text{NH}}_{4}^{ + }\), \({\text{HCO}}_{3}^{ - }\), Cl^–, \({\text{SO}}_{4}^{{2 - }}\), \({\text{NO}}_{3}^{ - }\)) and trace elements (Co, Ni, Cu, Zn, Cd, Pb, Sr, Ba, Mn) for 12 springs in the Bogorodsky and Losino-Petrovsky districts of Moscow oblast. The waters are slightly acidic to near-neutral (pH 5.5–7.5) with the mineralization ranging from 0.07 to 0.5 g/L, the total hardness is 0.63–5.7 mg-eq/L, the water composition is variable. Spring waters are divided into four groups: Cl–SO₄–HCO₃–(Mg)–Ca, (SO₄)–HCO₃–Cl–Na–Ca; (Cl)–HCO₃–Ca, and mixed. Based on the thermodynamic calculation using the Visual-MINTEQ program, it was found that the predominant dissolved species of Ba, Sr, Mn, Zn, Cd, Ni, and Co in the waters of the surveyed springs are free ions. For Cu and Pb, the factors for the formation of migration species are the predominant anions of water, as well as the presence of organic matter in water. The COD values and nitrogen compound in the waters of individual springs indicate that the formation of the spring water composition is resulted from the infiltration of atmospheric precipitation through the modern sediments subject to anthropogenic loading. The values of other sanitary–chemical indicators (mineralization, pH, total hardness, chlorides, sulfates, magnesium, sodium, manganese), the content of regulated trace elements are lower than their maximum permissible concentrations in drinking water.

Abstract The article focuses on the results of water parameters (COD, pH, electrical conductivity) and content of majorions (Ca2+, Mg2+, Na+, K+, \({\text{NH}}_{4}^{ + }\),\({\text{HCO}}_{3}^{ - }\)、Cl-,\({\{SO}}_{4}^{2 - }}\),\({\{NO}}_{3}^{ - }\)) 和微量元素（钴、镍、铜、锌、镉、铅、锶、钡、锰）。泉水呈微酸性至接近中性（pH 值为 5.5-7.5），矿化度为 0.07 至 0.5 克/升，总硬度为 0.63-5.7 毫克-当量/升，水的成分多种多样。泉水分为四类：Cl-SO4-HCO3-（Mg）-Ca、（SO4）-HCO3-Cl-Na-Ca、（Cl）-HCO3-Ca 和混合。根据使用 Visual-MINTEQ 程序进行的热力学计算，发现调查泉水中的钡、锶、锰、锌、镉、镍和钴的主要溶解物种是游离离子。至于铜和铅，形成迁移物种的因素是水中的主要阴离子以及水中有机物的存在。个别泉水中的化学需氧量值和氮化合物表明，泉水成分的形成是大气降水通过受人为负荷影响的现代沉积物渗透的结果。其他卫生化学指标值（矿化度、pH 值、总硬度、氯化物、硫酸盐、镁、钠、锰）以及规定的微量元素含量均低于饮用水的最大允许浓度。
