Environmental Remediation Design
8 weeks · 0 milestones
Produce a conceptual remediation design for a real or documented contaminated site, covering the selection and initial sizing of a remediation approach appropriate to the site conditions and contamination. The design must include: a site conceptual model summarising the contaminant sources, pathways, and receptors (source-pathway-receptor linkage), a remediation objectives statement (target concentrations for each contaminant based on risk-based or regulatory standards), a screening of at least 3 remediation technologies (in-situ chemical oxidation, pump-and-treat, bioremediation, soil excavation, or permeable reactive barrier — as applicable) against the site conditions, the selected approach with a conceptual design showing the treatment area and key design parameters, and an implementation phasing plan identifying the critical uncertainties that would need to be resolved through pilot testing. Preferred proof: a conceptual remediation design for a real project using site investigation data. Accessible alternative: conceptual remediation design using publicly available EPA Superfund site data (CERCLIS database, publicly accessible) — site investigation reports, groundwater monitoring data, and site maps are publicly available for hundreds of documented contaminated sites; EPA and Environment Agency remediation guidance documents are free. Proof artifacts: the site conceptual model and technology screening (analysis artifact) and the conceptual remediation design with phasing plan (documentation artifact). Verification: an environmental engineer reviews the technology selection — 'this site has low hydraulic conductivity; why did you select pump-and-treat, and how does that affect your predicted clean-up timeframe?' — requiring specific reasoning about your own site conditions.

Identify a real or realistic contaminated site scenario: contaminated groundwater, soil contamination, or industrial site with legacy pollutants. Document the site characterisation: contamination type (heavy metals, hydrocarbons, chlorinated solvents, etc.), concentration levels at different depths and locations, site hydrogeology (soil permeability, groundwater flow direction and depth), and relevant regulatory standards (EPA, Environment Agency, or equivalent). A thorough site characterisation is the foundation for selecting the correct remediation technology — the wrong technology for the site geology is a design failure.
Proof required
Submit your site characterisation report (≥800 words): contamination type and concentrations (cited from real site data, published case study, or regulatory guidance), site hydrogeology summary, and the regulatory cleanup targets you are designing to meet.
What gets checked
- Contamination concentrations are given as specific values at specific depths/locations — not general statements that contamination is 'present'
- Site hydrogeology addresses soil permeability and groundwater flow direction — both are required for technology selection
- Regulatory cleanup targets are cited with their source (EPA guidance values, UK soil screening values, or equivalent) — not stated without authority
