  1. 1Remediation for invasive species (e.g. [blank_start]Japanese Knotweed[blank_end]) - [blank_start]spraying[blank_end], disposal of plants and [blank_start]soil[blank_end] to approved facility, deep burial on site
    1. AJapanese Knotweed
    2. Bspraying
    3. Csoil
  2. 2Stages of a preliminary environmental assessment - [blank_start]Historical and present-day[blank_end] [blank_start]site use (and nearby)[blank_end], [blank_start]potential contaminants of concern[blank_end] and [blank_start]pollutant linkage conceptual model[blank_end]
    1. AHistorical and present-day
    2. Bsite use (and nearby)
    3. Cpotential contaminants of concern
    4. Dpollutant linkage conceptual model
  3. 3Environmental assessment of soil (increasingly rigorous) - [blank_start]non-residential (no plant uptake)[blank_end], [blank_start]non-residential (with plant uptake)[blank_end], [blank_start]residential (no plant uptake)[blank_end] and [blank_start]residential (with plant uptake)[blank_end]
    1. Anon-residential (no plant uptake)
    2. Bnon-residential (with plant uptake)
    3. Cresidential (no plant uptake)
    4. Dresidential (with plant uptake)
  4. 4Degree of contamination is not [blank_start]uniform[blank_end] and can be measured by statistical tests. [blank_start]Mean Value Test[blank_end] - identify 95% confidence limits of measured mean, then compare [blank_start]upper 95th percentile[blank_end] with Soil Guideline Value. [blank_start]Maximum Value Test[blank_end] - tests whether max value in sample set is an outlier
    1. Auniform
    2. BMean Value Test
    3. Cupper 95th percentile
    4. DMaximum Value Test
  5. 5Dig and Dump (removal of soil to landfill) is no longer the preferred option due to - traffic, [blank_start]landfill tax[blank_end], [blank_start]transport costs[blank_end]
    1. Alandfill tax
    2. Btransport costs
  6. 6When remediating contamination in situ, barriers around soil are used, what are the three types? [blank_start]Impermeable caps[blank_end], [blank_start]vertical[blank_end] (sheet piling, walls, grout [blank_start]curtains[blank_end]) and horizontal at depth ([blank_start]kerfing[blank_end])
    1. AImpermeable caps
    2. Bvertical
    3. Ccurtains
    4. Dkerfing
  7. 7Treatment - [blank_start]Pump and treat[blank_end] - intercept contamination, treat at the surface, re-inject. High [blank_start]installation[blank_end] and running costs, effectiveness in dilute parts of the contaminant plume.
    1. APump and treat
    2. Binstallation
  8. 8Treatment - [blank_start]Permeable reactive barriers[blank_end] - chemically active zone, removes or destroys contaminants.
    1. APermeable reactive barriers
  9. 9Treatment - bioremediation - natural micro-organisms biologically [blank_start]degrade[blank_end] contaminants. [blank_start]Aerobic[blank_end] - increases respiration of cultures, [blank_start]anaerobic[blank_end] - reducing conditions promotes the growth of anaerobic beasts.
    1. Adegrade
    2. Banaerobic
    3. CAerobic
  10. 10Treatment - [blank_start]phytoremediation[blank_end] - uses various plant types to remove/transfer/stabilise. Root [blank_start]uptake[blank_end]; release of microorganisms that promote [blank_start]degradation[blank_end]; chemical compounds [blank_start]immobilise[blank_end], metabolize contaminants.
    1. Aphytoremediation
    2. Buptake
    3. Cdegradation
    4. Dimmobilise
