“…After discontinuation of dewatering, the pits fill with groundwater, rainfall, and surface runoff to form emerging pit lakes or quarry lakes [3,23,24,27,31,32,37,41,42,62,63], which may have different depths [3,23,24,30,31,36,50,57,58,61,[64][65][66][67], surface area [3,23,24,32,36,37,50,57,58,66,67] and cubic capacities [23,36,50,67,68], depending on the type of the excavated material and mining technology used [23,30,36,37,56,61,65]. Depending on the geomorphological parameters of an open-excavation pit, hydrogeological conditions, the geological structure of the mine and its surroundi...…”

This paper presents the results of an analysis of the pace of filling one of the deepest European granite quarries with water. A DTM (digital terrain model) based on data from LiDAR ALS (light detection and ranging airborne laser scanning) was used to create a model of the pit of the Strzelin I granite quarry and to determine the reach and surface area of the direct catchment of the excavation pit. The increase in the volume of water in the excavation pit was determined. Analogue maps and DTM were used to calculate the maximum depth of the pit (113.3 m), its surface area (9.71 ha), and its capacity (5.1 million m3). The volume of water collected in the excavation pit during the years 2011–2018 was determined based on the analogue base map and the DTM. The result was 0.335 million m3. Based on the data made available by the mining company, the correlation of the DTM with the orthophotomap of the mining area and additional field measurements, the ordinates of the water level in the years 2011–2018 were determined. Initially, the water surface level in the quarry was located on the ordinate of 66.6 m a.s.l. (July 20, 2011). After the pumping of water was discontinued, the level rose to 96.1 m a.s.l. (January 28, 2018). The increase in the water volume in the quarry pit during specific periods was determined (actual retention increase). The obtained data on the volume of the retained water referred to the period during which it accumulated in the quarry. On average, the net increase in water retention in the excavation pit was 138.537 m3∙d−1, and the calculated net supply from the direct catchment (16.04 ha) was 101.758 m3∙d−1. The use of DTM and measurements of the water level in the excavation pit seem to be an efficient means of estimating the pace of spontaneous filling of the quarry with water supplied from the direct physiographic catchment.

“…Open cut mining has left a legacy of many thousands of mining pit voids worldwide with increasing frequency and scale [1][2][3][4]. Pit lakes are formed in mine voids once extractive and dewatering operations have ceased and water has accumulated through surface and groundwater inflows [3,5]. The water quality of pit lakes is variable and is an aspect determined by the geology of the void, water inflow quality, groundwater quality and surrounding activities and land uses including the presence of waste rock [6,7].…”

Pit lakes may form in mining voids that extend below groundwater level after mining ceases and many have been found to have elevated metals concentrations and low pH through acidic and metalliferous drainage (AMD). Pit lakes are often used for recreational activities including swimming, fishing and boating and poor water quality may present health risks to recreational users. Pit lakes also provide the opportunity for additional water resource uses. The Collie Coal Basin in south-western Australia currently has a number of pit lakes with moderate AMD effects which are also used for recreational pursuits. Twelve hundred questionnaires were mailed to selected addresses in the Collie shire with an additional 170 questionnaires to specific interest groups. Participants were asked about the type of activity, frequency and duration and any health symptoms experienced after use of the lakes. Two hundred and fifty questionnaires were returned, which comprised 176 returns from the random sample and 74 from the targeted sample. Three pit lakes with elevated metals concentrations and low pH were used for recreational purposes by 62% of respondents. This was mostly in summer with swimming the most common activity. Of all respondents 52% were concerned about lake water quality and 38% using the lakes reported a variety of symptoms. Recreational use of Collie pit lakes did not represent a health risk for most of the surveyed population due to the low frequency and duration of use, however health risks may be elevated in sensitive users such as children and those consuming seafood from the lakes. Comprehensive water quality monitoring for chemicals and further characterisation of recreational use of pit lakes is warranted to more comprehensively assess the potential health risks to recreational users. Post closure mine plans need to consider potential future community uses combined with assessments of water quality and physical characteristics to reduce the potential for adverse health and safety impacts.

“…These are former excavations of clay, sand and gravel [18,[25][26][27], stone quarries [20,[26][27][28][29][30], open-cast coal [18,[25][26][27][31][32][33][34] and lignite mines [26,27,[31][32][33][34][35][36][37], as well as open-cast ore metal mines [18,25,27,34]. When the mining process, and thus the dewatering of the pit, is discontinued, they often fill with groundwater, rainfall and surface runoff, which results in the emergence of mine or quarry lakes [17,20,21,36,[38][39][40][41][42][43][44][45][46][47][48][49].…”

This paper presents the results of bathymetric measurements of quarry lakes located in inactive granite quarries (Poland, Lower Silesia, County Strzelin), which were used, among other reasons, to determine the surface area, depth, and volume of water retained in the analysed quarry lakes. The usability of water in quarry lakes for agricultural irrigation was also assessed, based on the FAO Guidelines and the PN-84/C-04635 standard. The average surface area of the analysed quarry lakes was 0.99 ha, the average depth was 6.0 m, and the maximum depth was 14.3 m. At the same time, the total volume of the retained water amounted to 307.8 thousand m3, which accounts for 10.6% of the retention capacity of water reservoirs situated in the catchment of the Oława River. The average values of water quality indicators were as follows: electrical conductivity—0.332 mS × cm−1; sodium adsorption ratio—0.56; total dissolved solids—212.4 mg/L; water pH—7.8; BOD5—2.4 mgO2/L. The mean concentrations of ions had the following values: nitrates—0.91 mgN-NO3−/L; sulphates—176.3 mg SO42−/L; chlorides—36.56 mg Cl−/L; sodium ions—14.8 mg Na+/L; calcium—41.3 mg Ca2+/L; magnesium—7.48 mg Mg2+/L; manganese—0.1 mg Mn/L; and iron—0.01 mg Fe/L. The concentrations of water quality indicators that were recorded for the analysed Strzelin quarry lakes were similar to those observed in natural lakes and uncharged water bodies. Water from the analysed quarry lakes met (with some minor limitations) the requirements that enable them to be used for agricultural irrigation. The volume of the water retained in the analysed quarry lakes constitutes an important element of the total balance of water retained in all the reservoirs, ponds, and all Strzelin quarry lakes situated in the catchment of the Oława River, accounting for 10.6% of the total volume of retained water. The article presents the innovative concept of the possibility of using water from quarry lakes in agriculture, based on their quantity and quality and the requirements for the purpose for which they will be used, e.g., for agricultural irrigation.
