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
- AJapanese Knotweed
- Bspraying
- Csoil
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]
- AHistorical and present-day
- Bsite use (and nearby)
- Cpotential contaminants of concern
- Dpollutant linkage conceptual model
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]
- Anon-residential (no plant uptake)
- Bnon-residential (with plant uptake)
- Cresidential (no plant uptake)
- Dresidential (with plant uptake)
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
- Auniform
- BMean Value Test
- Cupper 95th percentile
- DMaximum Value Test
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]
- Alandfill tax
- Btransport costs
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])
- AImpermeable caps
- Bvertical
- Ccurtains
- Dkerfing
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.
- APump and treat
- Binstallation
8Treatment - [blank_start]Permeable reactive barriers[blank_end] - chemically active zone, removes or destroys contaminants.
- APermeable reactive barriers
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.
- Adegrade
- Banaerobic
- CAerobic
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.
- Aphytoremediation
- Buptake
- Cdegradation
- Dimmobilise
11Treatment - [blank_start]solidification[blank_end] (physical)/[blank_start]stabilisation[blank_end]) chemical) - reduce [blank_start]K[blank_end] and metal solubility, cement/[blank_start]organophilic[blank_end] clays
- Asolidification
- Bstabilisation
- CK
- Dorganophilic
12Treatment - [blank_start]soil washing[blank_end] - dissolving and/or separating suspending contaminants into wash water which can be dosed with chemicals to improve the process. Concentrating contaminants into smaller volume of soil by particle size separation and '[blank_start]attrition[blank_end]' scrubbing.
- Asoil washing
- Battrition
13Treatment - [blank_start]soil vapour (vacuum) extraction[blank_end] - vacuum applied to soil through boreholes/trenches, induces airflow through unsaturated soil, removes volatile contaminants, extracted air treated to recover or destroy contaminants, air injected ([blank_start]sparging[blank_end]) to aid process.
- Asoil vapour (vacuum) extraction
- Bsparging
