Response Action Planning

Trinity Environmental helps clients develop the most cost-effective solutions to address their affected properties. Often, contaminated sites may be remediated to achieve background values (e.g., under the Texas Spill Rules) or to generic clean-up values {e.g., Tier 1 Protective Concentration Levels (PCLs) under TRRP Remedy Standard A}. At more complex sites, a response action plan (RAP) is developed to remediate the site (e.g., under TRRP Remedy Standard B). The RAP defines the objectives, design, performance measures, post-response action care, and implementation schedule for the response action.

There are a variety of technologies available to remediate contaminated sites. Examples of innovative technologies currently being utilized for soils and sludges include soil flushing, vitrification, phyto-treatment, plasma high temperature metals recovery, soil vapor extraction, soil washing, solvent extraction and thermal desorption. Innovative technologies being applied to groundwater remediation include air sparging, intrinsic and enhanced bioremediation, dual-phase extraction, in-situ oxidation, and surfactant flushing. Traditional remedial alternatives consist of options such as excavation and disposal of contaminated soils, groundwater pump and treat, sludge solidification/stabilization, mechanical soil aeration, and incineration.

In order to select an appropriate remedial option for a site, one must understand: the nature, degree, and extent of contamination; the current and future risk to human health and the environment; and the overall objective of the remediation (i.e., restoration of land for industrial use, or cleanup to levels protective of residential land use). TRINITY works with clients to develop remedial objectives for contaminated sites given environmental health and safety concerns, local regulatory requirements, current/future land use, engineering feasibility, and cost. Then, we evaluate a range of remedial alternatives to identify a cost-effective remedy that achieves the desired cleanup goals.

TRINITY has experience in planning and implementation of remedial actions including system design, cost estimation, preparation of bid specifications, selection of qualified contractors, construction QA/QC testing, scheduling, and project management. Our personnel are focused on making certain that every job is performed safely, according to specifications, on schedule, and within budget.
