Going Green
Even before the “green” groundswell, Arrowhead has been practicing “green remediation strategies” in the form of cost avoidance practices and beneficial use alternatives for onsite contaminated and non-contaminated materials, for many years. For example, in its effort to work efficiently and reduce client costs, Arrowhead regularly utilizes pre-excavation sampling and “hot-loading” of contaminated materials to eliminate double handling by excavation equipment, needless transportation of roll-off containers or stockpiling. By eliminating re-handling of materials, multiple trips to the site by multiple parties, construction of onsite stockpile facilities, Arrowhead minimizes the carbon footprint of a remediation effort. Arrowhead also recommends recycling demolition debris/concrete for erosion control structures, backfill and other civil construction uses.
Arrowhead’s innovative, “green remediation” practices include the use of cleaned, formerly contaminated groundwater for geothermal heating/cooling of remediation and adjacent facilities prior to discharge or, ideally, re-injection to the groundwater aquifer.
