The inorganic geochemistry of hydraulic fracturing fluids is reviewed with new insights on the role of entrapped formation waters in unconventional shale gas and tight sand formations on the quality of flowback and produced waters that are extracted with hydrocarbons. The rapid increase of the salinity of flowback fluids during production, combined with geochemical and isotopic changes, indicate mixing of the highly saline formation water with the injected water. The salinity increase suggests that the volume of the injected water that is returned to the surface with the flowback water is much smaller than previous estimates, and thus the majority of the injected water is retained within the shale formations. The high salinity of the flowback and produced water is associated with high concentrations of halides, ammonium, metals, metalloids, and radium nuclides that pose environmental and human health risks upon the release of the hydraulic fracturing fluids to the environment.

This article discusses the joint work of Professor W.M. Edmunds (UK) with his Russian colleagues. He had an important role in the development of hydrogeochemistry in Russia. He was an initiator of the joint research projects with Russian scientists and was actively supporting the idea of holding international conferences on the territory of Russia. In addition, as a follower of V.I. Vernadsky, he was actively promoting Vernadsky's ideas outside of Russia.

After mine closure and subsequent shutdown of the dewatering system, groundwater rebound led to drainage outflow from the Casargiu gallery (Montevecchio mine, SW Sardinia, Italy) since 1997. As compared with the first discharge, a very high contamination level still persists after almost 20 years of flushing. Mine drainage (20-70 L s-1; pH 6.0±0.2; Zn-Mg-Ca-SO4 composition) flows into the Rio Irvi. Abundant precipitation of amorphous Fe(III)-(oxy)hydroxides occurs. Moreover, sulfate-bearing green rust is observed to flocculate in the reach of the Rio Irvi where pH is still circumneutral. Water sampling along this stream shows a pH decrease from 6.0 to 4.0 and a significant removal of Fe (46%) and As (96%), while sulfate, Zn, Mn, Co, Ni and Cd show small variations downstream. Lead is initially adsorbed onto Fe(III)-(oxy)hydroxides, then desorbed as pH drops below 5.4. A conservative estimation of dissolved metals discharged into the Mediterranean Sea is significant (e.g. 900 kg day-1 Zn, 1.4 kg day-1 Cd, 5 kg day-1 Ni).
自1997年起,在关闭矿井和随后关闭脱水系统后,地下水反弹导致Casargiu矿(意大利撒丁岛西南部Montevecchio矿)排水流出。与首次排放的污水相比,经过近20年的冲厕后,污染程度仍然非常高。矿井排水(20-70 L s-1;pH值6.0±0.2;Zn-Mg-Ca-SO4组成)流入Rio Irvi。大量无定形铁(III)-(氧)氢氧化物析出。此外,在pH值仍为环中性的里奥伊尔维河段,观察到含硫酸盐绿锈絮凝。沿河水样pH值从6.0降至4.0,Fe(46%)和As(96%)被显著去除,而硫酸盐、Zn、Mn、Co、Ni和Cd在下游变化较小。铅最初吸附在Fe(III)-(氧)氢氧化物上,然后在pH值低于5.4时解吸。对排入地中海的溶解金属的保守估计是重要的(例如,每天900公斤锌,每天1.4公斤镉,每天5公斤镍)。
