“…In fact we have devoted attention to many in situ nature‐based treatment techniques as part of this regular column series, starting with in situ metals precipitation in 2009 and moving to engineered anaerobic bio‐oxidation, temperature‐activated auto‐decomposition reactions, and enhanced reductive dichlorination (Suthersan et al , , , ). Last year alone we wrote about reactive mineral‐mediated abiotic contaminant transformation, bioreactors for high concentration contaminant mixes, and bioremediation of 1,4‐dioxane (Horst et al , , ).…”

Important reactive minerals are commonly created during in situ groundwater remediation activities; for example, iron sulfides formed during enhanced reduction approaches can abiotically degrade many chlorinated solvents. However, cost‐effective tools to evaluate these treatment processes in field applications are limited and the collection of samples to evaluate in situ mineral formation is costly due to drilling requirements. The new passive Min‐Trap sampler is a simple and cost‐effective tool that can directly measure the formation of reactive minerals in situ without the need for additional drilling or soil core collection. The methods presented here describe how Min‐Traps deployed in conventional monitoring wells can measure reactive minerals and how these minerals can be identified through commercially available analytical methods. Several examples are presented that show how Min‐Traps can be used to characterize the rate and spatial variability of reactive mineral precipitation and these data may support operation and optimization decisions.

This column reviews the general features of PHT3D Version 2, a reactive multicomponent transport model that couples the geochemical modeling software PHREEQC-2 (Parkhurst and Appelo 1999) with three-dimensional groundwater flow and transport simulators MODFLOW-2000 and MT3DMS (Zheng and Wang 1999). The original version of PHT3D was developed by Henning Prommer and Version 2 by Henning Prommer and Vincent Post (Prommer and Post 2010). More detailed information about PHT3D is available at the website http://www.pht3d.org.The review was conducted separately by two reviewers. This column is presented in two parts.
