“…High concentrations of soluble salts, trace elements (natural or added), and various mud additives in drilling mud systems have been shown to have deleterious effects on soil quality and plant growth (McFarland, Ueckert, Hons, & Hartmann, 1994; Zvomuya, Larney, DeMaere, & Olson, 2009; Zvomuya, Larney, McGinn, Olson, & Willms, 2008). Other studies have reported either no impact or actual benefits to soil quality and plant growth attributed to favorable pH change, the addition of nutrients, and improvements in soil physical properties (Bauder, Barbarick, Ippolito, Shanahan, & Ayers, 2005; Saint‐Fort & Ashtani, 2014; Yao & Naeth, 2015; Yao, Naeth, & Chanasyk, 2014; Zvomuya, Larney, Willms, Beck, & Olson, 2011).…”

Landspraying while drilling (LWD) is an approved disposal method for water‐based drilling mud (WBM) systems in western Canada, where the mud is applied either on arable or vegetated land. This study examined the effects of a single LWD application (0, 15, 20, 40, or 80 m3 ha−1) on native prairie soil properties. Results from the study showed a significant increase in Na concentration and sodium adsorption ratio (SAR) in the 0‐ to 7.5‐cm depth. However, the highest SAR attained (3.46) after application at the 80 m3 ha−1 rate remained below levels considered detrimental to soil structure. Electrical conductivity (EC) also increased with the LWD rate but peaked at levels (447 μS cm−1 in the 0‐ to 2.5‐cm depth) much lower than the threshold for most plant species, and the effects on EC had disappeared by the end of the first year of mud application. Available P concentration (modified Kelowna method), averaged across sampling times and the two depths (0‐ to 2.5‐ and 2.5‐ to 7.5‐cm), increased from 7.4 to 11 mg kg−1 as LWD rate increased from 0 to 80 m3 ha−1. Although the available P remained at concentrations suboptimum for most crops, such concentrations may impact native prairie vegetation adapted to very low P. Drilling mud applications generally had no significant effect on available N. The application of WBM systems on the native prairie at recommended rates in western Canada may not be detrimental to soil quality and plant growth in this ecosystem.

“…Zvomuya et al (2011) demonstrated that soluble nutrient elements, such as N, P, and Mg in above-ground plant tissues increased with increasing loading rate in samples taken 45 days after SDFs application [13]. Yao et al (2014Yao et al ( , 2015 showed that twice-used SDFs significantly increased barley above-ground biomass, and all SDFs treatments increased the available potassium relative to that in the control [14,15]. Despite studies investigating the effects (negative and/or positive) of SDFs on various crops, comprehensive data on the underlying mechanism are limited, and the effects on the early growth of crops remain unclear.…”

The use of drilling waste for land reclamation is a cost-effective way to improve soil fertility and to decrease landfills. However, the potential phytotoxic and cytotoxic effects of this waste on crops have not been investigated in detail. Here, we evaluated the toxicity of spent drilling fluids (SDFs) from a natural gas field using the non-target plant Zea mays L. (maize). Four different concentrations of SDFs (2%, 4%, 6%, and 8%, w/w) were used to test the toxic effects in two soils (aeolian and loessal). Different endpoints, including germination, root elongation, reactive oxygen species (ROS) accumulation, antioxidant activity, mitotic index, and chromosomal abnormalities, were used to test the effects of SDFs after four days of exposure. Higher levels (≥6%) of SDFs inhibited seed germination and root growth, and altered the oxygen status by increasing hydrogen peroxide (H2O2) and inhibiting superoxide ion (O2−) accumulation in the roots. SDFs-induced oxidative stress caused member damage, exacerbated cell injury, and reduced cell viability in the roots, compared with those untreated plants. The plants responded to high SDFs levels (≥6%) by upregulating antioxidants such as peroxidase, superoxide dismutase ascorbate peroxidase, and proline. A reduction in the mitotic index and induction of chromosomal abnormalities in root meristematic cells were indicators of the cytotoxicity of SDFs in maize seedlings. The upregulation of antioxidants due to the change of ROS and the induction of chromosomal abnormalities were more severe in roots grown in aeolian soil than in those grown in loessal soil. The present results provide insight into the mechanism underlying the phytotoxicity and cytotoxicity of SDFs and have implications for land reclamation to minimize deleterious effects on non-target crops.
