Site Assessment Calculators
On-Site is an online assessment tool developed by Land Research Program to provide modelers and model reviewers with prepackaged tools (calculators) for performing contaminated site assessments. The philosophy behind On-Site is that the convenience of the prepackaged calculators helps provide both consistency for simple calculations and access to methods and data that are not commonly available. The components of On-Site are:
- Formulas for transport parameters (gradient, retardation factor, estimated dispersivity, seepage velocity, effective solubility, etc.)
- Simple transport models [one-dimensional transport, leaching from a Non-Aqueous Phase Liquid (NAPL) source, plume diving]
- Unit conversions (hydraulic conductivity, Henry's Law, etc.).
Revitalization Decision Support Tool (SMARTe)
SMARTe is a joint effort of the US-German Bilateral Working Group, EPA, and the Interstate Technology Regulatory Council (ITRC) Brownfields Team. The online decision-support tool is intended to be used by brownfield project stakeholders for assessing both market and non-market costs and benefits of redevelopment options, clarifying both private and public financing options, evaluating and communicating environmental risks, and easing access to pertinent state-specific information related to specific projects. SMARTe provides the analytical tools needed to implement and integrate each component of the decision process.
Wave Take Facility
To improve international scientific understanding and responses to oil spills at sea, ongoing cooperation and funding between Fisheries and Oceans Canada and the Land Research Program have resulted in the development of a Wave Tank at the Bedford Institute of Oceanography in Dartmouth, Nova Scotia. The facility allows scientists to simulate a wide range of breaking wave energy levels at sea, providing the necessary mixing conditions for dispersants to work effectively while conducting research into chemical dispersants that can be used to breakup oil slicks. It also allows scientists to assess risk, explore the potential chronic effects of oil around offshore platforms, and improve guidelines and/or regulations on the use of dispersants.
In Situ Chemical Oxidation
Land Research Program scientists are continuing to investigate the fundamental and applied aspects of In-SituChemical Oxidation (ISCO). ISCO introduces a chemical oxidant into the subsurface for the purpose of transforming ground water or soil contaminants into less harmful chemical species. It is currently being used at old sites to reduce the contaminant mass flux from source areas to downgradient pump and treat systems and/or to reduce anticipated cleanup times required for natural attenuation and other remedial options.
Remedial Technology Documents
The Land Research Program synthesizes various research areas and publishes research reports and guidance documents. The documents are intended to provide an understanding of the scientific issues and applications of technology for EPA regional offices and project managers. Topics include Monitored Natural Attenuation remedies, capstone reports on Permeable Reactive Barriers, Dense Non-Aqueous Phase Liquid (DNAPL) remediation, vapor intrusion assessment, and others.
