Hydraulic fracturing of non-conventional (tight and shale) deposits is a controlled process of technological fluid injection into a deposit. The fluid consists mainly of water and chemical components ( Fig. 1) and the injection is done with high effectiveness (6-20 m 3 /min) with high pressureup to 100 MPa, which cracks rocks in a deposit and creates chains of cracks, or clefts.Further injecting the fluid results in propagation of cracks to a size determined in a technological project. After opening the crack, a proppant material (sand of proper granulation and mechanical strength) is added to the technological fluid and gets into the cracks and stops their closure. Simultaneously, it creates access for gas flowing to an excavation slot [1][2][3][4].Compositions of technological fluids used in hydraulic fracturing depend on the geological formation of a deposit and on the type of well (vertical or horizontal).During development of a fracturing fluid and selection of additives, the following factors should be taken into account: Pol. J. Environ. Stud. Vol. 24, No. 5 (2015), [2185][2186][2187][2188][2189][2190][2191][2192][2193][2194][2195][2196] AbstractAn analysis of environmental threats showed that the complete influence of shale gas production on the environment is bigger than in the case of gas production from a traditional oilfield. Hydraulic fracturing of shale, done on a much larger scale, results in huge amounts of liquid waste that must be managed in a rational way. An optimum solution to this problem is reusing flowback water to develop fluids for later fracturing. This article discusses the composition of the fluids used in hydraulic fracturing of non-conventional deposits as well as the flowback water. In the case of the examined liquids, toxicological tests have been carried out using microbiotests of ToxKit types Microtox, MARA, Daphtoxkit F magna, and Thamnotoxkit F. The research was done on a sample of fluids for hydraulic fracturing, and on flowback water obtained in hydraulic fracturing of shale formations in Poland. The tests are essential for correctly managing flowback waters after fracturing.

“…Those authors observed that higher toxic effects on the early stages of the runoff were gradually reduced, and that 90% of toxic effects were associated with the first 20% of the total runoff volume. Even though the toxic effects posed by wood-related compounds have been demonstrated [9,10,11,6,4], little is know concerning the intra-storm magnitude, variability and possible existence of toxic first flushes from stormwater runoff generated in log-yards. The aim of this paper was to evaluate the magnitude and the intra-storm variability of the toxic effects posed by stormwater runoff originated from a log-yard during single storm events.…”

The effects posed by stormwater runoff from an industrial log-yard on the microalgae Scenedesmus subspicatus have been investigated. The effects of stormwater runoff sampled during two rain events on the microalgae were determined in different concentrations (% v:v). The test organisms were exposed to the stormwater runoff 96h and the percentage change in growth rates in relation to a control culture were measured at exposure times of 24h, 48h, 72 and 96h. Whereas the runoff from the first rain event posed in most cases growth stimulatory effects, the runoff from the second rain event inhibited algae growth. Differences in runoff physico-chemical characteristics combined with the hydrological factors of each rain event explained these opposite effects. The occurrence of the "first flush" phenomenon was studied and the results confirmed such occurrences in the second rain event. On the basis of normalized inhibitory effects and runoff volume, it was found that 42, 51 and 50% of the inhibitory effects during exposures of 24, 48 and 72h were associated with the initial 4% of the total discharged volume. To conclude it can be stated that since the stormwater runoff of only 2 rain events posed negative effects on the test organisms, the potential environmental threats posed by these waters during the entire hydrological year needs to be better understood in order to propose an adequate management program.

Acidic leachates of pine bark, caused by desorption of water-soluble phenolic acids, are toxic to some aquatic organisms [10,11].

Abstract. This study demonstrates the application of FT-IR spectroscopy for investigating the remediation of pink water with the low cost adsorbent pine bark. The removal of 2,4,6-trinitrotoluene (TNT) from pink water by adsorption to pine bark was accompanied by a reduction in intensities of peaks at 1544 and 1347 cm -1 in the spectra of acetonitrile extracts of the pine bark. Hierarchial cluster analysis differentiated samples with high (30-180 mg/L) and low (0-4 mg/L) TNT concentrations, demonstrating the potential of this approach as a quick screening method for the control of the removal of TNT from pink water. The amount of lignin in pine bark was inversely proportional to the size of the pine bark particles, while the concentration of phenolic hydroxyl groups increases with increasing size of pine bark particles. FT-IR spectra showed that as well as TNT, pine bark can also adsorb nitramine explosives such as RDX and HMX.
