“…These authors postulate that the unrealistically high water / rock ratios, reactive surface area (due to disaggregation), and mixing in batch experiments maintain mineral phases under saturated and thus mass transfer rates artificially high. Only Yang et al (2014b) found comparable release rates for both experimental types.…”

“…In terms of impact on drinking water quality, aside from a limited number of exceptions, trace element concentrations remained well below national and international drinking water limits in all field experiments in which they were measured Cahill et al, 2014;Kharaka et al, 2010;Mickler et al, 2013;Peter et al, 2012;Trautz et al, 2013;Yang et al, 2013a;Yang et al, 2014b). Exceptions included Al values over 10x the WHO guidelines (Cahill et al, 2014), two samples that exceeded Ni drinking water levels , and some pH, Fe, Mn and Zn values that exceeded secondary standard levels where effects are deemed to be cosmetic or aesthetic (Yang et al, 2014b).…”

“…It is also being used to interpret observed groundwater changes at CO 2 injection field experiments Yang et al, 2013a;Yang et al, 2014b;Zheng et al, 2012). For these studies, the most commonly applied models are TOUGHREACT (Xu et al, 2004) and PHREEQC (Parkhurst and Appelo, 1999).…”

“…In carbonate rich aquifers pH changes will be limited due to buffering but alkalinity and DIC will increase significantly with the dissolution of calcite or dolomite, whereas in carbonate poor aquifers pH will decrease sharply. Thus authors have suggested the use of DIC (Romanak et al, 2012b), DIC and pH (Trautz et al, 2013), or DIC, pH, and  13 C DIC (Yang et al, 2013a;Yang et al, 2013b), while Yang et al (2014b) used modelling results to suggest that pCO 2 and DIC may be the best compromise in all mineralogical settings. Some major ions, such as Ca, Mg, Fe, and Mn, have shown CO 2 induced changes in controlled injection experiments (Cahill et al, 2014;Kharaka et al, 2010;Trautz et al, 2013), however their reactivity means that data interpretation is problematic.…”

This paper reviews research into the potential environmental impacts of leakage from geological storage of CO 2 since the publication of the IPCC Special Report on Carbon Dioxide Capture and Storage in 2005. Possible impacts are considered on onshore (including drinking water aquifers) and offshore ecosystems. The review does not consider direct impacts on man or other land animals from elevated atmospheric CO 2 levels. Improvements in our understanding of the potential impacts have come directly from CO 2 storage research but have also benefitted from studies of ocean acidification and other impacts on aquifers and onshore near surface ecosystems. Research has included observations at natural CO 2 sites, laboratory and field experiments and modelling. Studies to date suggest that the impacts from many lower level fault-or well-related leakage scenarios are likely to be limited spatially and temporarily and recovery may be rapid. The effects are often ameliorated by mixing and dispersion of the leakage and by buffering and other reactions; potentially harmful elements have rarely breached drinking water guidelines. Larger releases, with potentially higher impact, would be possible from open wells or major pipeline leaks but these are of lower probability and should be easier and quicker to detect and remediate.

The marginal facies of the Triassic rift basins in the eastern United States are poorly documented, particularly on the hinge or hanging wall margins. This study presents a lithological description and multiscale petrophysical analysis of basement rocks, overlying marginal facies of the early synrift strata, and the basal contact of the Palisade Sill that were drilled and cored in the northeastern part of the Newark Basin, near its terminus. The expression of the Stockton Formation differs from that in the central basin in having thinner layers, with uncertain temporal relationship to the type area. The bottom 50 m is lithologically distinct with brick‐red to dark‐purple mudstones and sandstones, abundant gypsum‐filled fractures, and a thin zone with anomalously high uranium concentration, not associated with organic‐rich mudstones as other occurrences in the basin. The crystalline basement is apparently Fordham gneiss, overlain by a thin sandstone layer and a dark‐purple hydrophilic mudstone. Despite the abundance of coarse‐grained strata and multiple sets of tectonic fractures, hydraulically transmissive zones are sparse, and do not uniquely correlate to fracture and/or matrix characteristics. Enhanced transmissivity may exist along intrusion boundaries due to enhanced thermal fracturing, but more hydraulic data are needed to verify it. Comparison of petrophysical data in two boreholes ∼210 m apart shows no direct correlation of individual lithological units and their hydraulic properties, although the overall formation characteristics are similar. The results highlight challenges for outcrop correlation at the marginal edges of the rift basins and estimating reservoir properties of these heterogeneous formations.

Four‐stage single‐well push‐pull (SWPP) tracer tests, including injection, chasing, resting, and pumping, were conducted in a fractured aquifer at Newark basin. An anomalous transport phenomenon observed in the SWPP tests is the linear decline of breakthrough curves (BTCs) at late time with slope of −1.8 in log‐log plots. A time‐dependent fractional model is developed to interpret the anomalous transport behavior. This model considers a time‐dependent power law memory function and a time‐dependent fractional advection‐dispersion operator. The fractional advection‐dispersion equations (fADE) are solved in a radial coordinate system using the implicit Euler method. A semi‐analytical solution of the first‐order rate‐limited mobile‐immobile model (FORMIM) is derived for comparison. It is found that both the nonlocal transport in time and space can produce the long‐tailed BTC. A smaller time‐fractional or space‐fractional index leads to a lower peak concentration and a larger late‐time slope. The mass distribution of the fractional‐in‐space (FS) model exhibits power law decline at the leading plume edge. Early breakthrough during pumping is not observed because the mobile mass at the start of pumping is nonzero and more concentrated near the wellbore. The capacity ratio is an important factor that affects the peak concentration. A larger capacity ratio leads to greater peak concentration. A smaller time‐fractional index in the injection, chasing, or resting stage will move the BTC downward and the slope of the late time BTC is determined by the space‐fractional index over all stages and the time‐fractional index in the pumping stage. The capability of the existing models to recover the BTC of the SWPP test is discussed and some guidelines for how to choose the appropriate model to interpret the SWPP test data are proposed.
