“…Poland was the leader of shale gas exploration until the end of 2016 when efforts ceased, largely due to disappointing production rates from test wells (Cantoni 2018). During the period 2010-2016, a total of twenty-eight horizontal wells were hydraulically stimulated (Pyssa 2017), of which seven sites were independently monitored by the Polish Geological Institute (English acronym PGI-NRI; Konieczyńska et al 2015), producing limited baseline data, e.g. one single-event sampling for water bodies, 1.5 months of background seismicity at the Łebień site (Konieczyńska et al 2011).…”

Baseline groundwater monitoring for shale gas extraction: definition of baseline conditions and recommendations from a real site (Wysin, Northern Poland)

Public concerns have been raised regarding the use of hydraulic fracturing for shale gas extraction and its potential impact on the environment. The absence of baseline monitoring data in the US experience has been identified as a major issue. Here, results from a 6-month groundwater baseline monitoring study near an active shale gas pad in northern Poland are presented. The data collected in dedicated boreholes include groundwater samples analysed for inorganic constituents, dissolved gases and stables isotopes (δ 2 H and δ 18 O) and downhole temperature and conductivity measurements at 15-min intervals. A robust statistical analysis combined with an estimation of data uncertainty helps to identify spatial and temporal variability within the datasets. As a result, baseline conditions are defined using confidence intervals around the mean on a per-well basis and these will serve for future reference for this site. The groundwater chemical composition is similar to regional background levels and typical of Quaternary aquifers in the region. It is also consistent with previous baseline monitoring carried out by the Polish Geological Institute. Only manganese and bromide occur in groundwater at concentrations above Polish drinking water standards. Based on this work, the paper provides some recommendations for future baseline monitoring and identifies areas for future research such as use of statistics for high-frequency datasets.
