“…The following types of water occur in the first zone up to a depth of about 500 m: fresh or low salinity water, as well as infiltration water and water of various genetic types with the hydrostatic nature of the energy potential (suspended, ground, interformation nonartesian and formation artesian waters). In the second zone, at depths of 500-1500 m, there are formations of artesian waters of chloride-calcium, sometimes chloride-magnesium and hydrocarbonsodium types with mineralization of 5-10 g/l and hydrostatic nature of energy potential (Tikhomirov, 2018). Below, at depths of 1500-4000 m, in the stagnation zone, there are mainly artesian waters with high mineralization (dozens -the first hundreds of grams per liter) of chloride-calcium type, whose pressures are determined by geostatic pressure, as well as by exfiltration and sedimentation origin (entrapped water), and the role of drainage, rejuvenated and lithogenic waters is increasing with the depth, which determines the hydrogeological inversion (decrease) of mineralization (Adamenko, 2017, Shokri-Kuehni, 2017.…”

While developing hydrocarbon (oil and gas) deposits, it is necessary to drill into shallow formations of fresh (drinking) water, and this causes the filtrate invasion from the open wellbore into these formations. A mathematical model of this process was created; an analysis of the influence of the identified by the process features filtration zones was performed, and it was shown that the zones of the mud crust and interstitial colmatation are dominant. The filtrate invasion can significantly impair the quality of fresh water and cause environmental damage.

Seasonal variation of hydrochemical characteristics of open-pit groundwater near a closed metalliferous mine in O’Kiep, Namaqualand Region, South Africa

In this study, the hydrochemical characteristic changes of open-pit groundwater (OPGW) near a closed metalliferous mine proposed for drinking and irrigation usage were investigated. Water samples from an OPGW in O'Kiep were collected in April (dry season) and August (wet season), 2017. Data analysis methods, such as the coefficient of variation, correlation coefficient, piper trilinear plot analysis and sodium adsorption ratio (SAR) among others were used to assess of the seasonal variation in the OPGW quality. The hydrochemical characteristics of the OPGW were also compared with drinking water guidelines. Based on the results, it was evident that the OPGW quality varied seasonally. The most abundant cation and anions were Ca 2+ and SO 4 2− , with recorded concentrations of 631 and 6020 mg/L, (dry season); 541 and 4450 mg/L (wet season), respectively. The OPGW was relatively rich in SO 4 2− > Cl − > Mg 2+ > Ca 2+ > Na + > K + during the dry season; however, these cations and anions were reduced during the wet season with Cl − and Na + subsequently increasing. PHREEQC indicated that cation exchanges played a significant role in the OPGW chemistry with Sb and Ca appearing to be the minerals with the highest precipitation potential followed by Cu 7 S 4 and Blaubleil, respectively. Covellite, CdSe 2 and NiSe were likely to be in equilibrium while Ca 3 Sb 2 will remain in a dissolution state. Furthermore, the seasonal fluctuation in the OPGW quality characteristics was attributed to the water table level fluctuations and the water quality did not satisfy the guidelines stipulated by the South African National Standard, SANS241-1 (2015) and World Health Organisation, WHO (2011). The trilinear piper plot classified the OPGW into three types: Ca 2+ -Mg 2+ -Cl − -SO 4 2 ; Ca 2+ -Mg 2+ -F − ; and Ca 2+ -Mg 2+ -SO 4 2− . Overall, the SAR values were within the permissible levels for irrigation purposes; however, long-term use of the OPGW might be detrimental for plant growth.
