  14. 14. CN 301 – GEOENVIROMENTAL ENGINEERINGEXPLORATORY TECHNIQUE
  15. 15. CN 301 – GEOENVIROMENTAL ENGINEERING GRAB SAMPLING ADVANTAGES DISADVANTAGES• Low cost • Depth limit: surface-• Quick 0.5m• No access • Impractical in restrictions difficult soil• Minimal soil conditions disturbance • Care is required to ensured the quality of sample recovered
  16. 16. CN 301 – GEOENVIROMENTAL ENGINEERING HAND AUGER, SPLIT BARREL DEVICES ADVANTAGES DISADVANTAGES• Low cost • Depth limit: 2-3 m (with ease)• Quick • Impractical in difficult soil conditions• No access • Care is required to restrictions ensured the quality of• Minimal soil sample recovered • Limited ability to disturbance observe the nature of the material • Labour intensive
  17. 17. CN 301 – GEOENVIROMENTAL ENGINEERING TEST PITS ADVANTAGES DISADVANTAGES• Lower cost than • Extent of soil disturbance, boreholes occupational exposure,• Relatively quick compaction• Ability to make • Depth limit: 3-5m depending on detailed excavator observations of the • Impractical in unstable strata soil conditions and hard rock• Ability to recover • Not suitable for samples installing monitoring bores due to
  18. 18. CN 301 – GEOENVIROMENTAL ENGINEERING BOREHOLE ADVANTAGES DISADVANTAGES• Minor disturbance of soils • More expensive than• Limited occupational other techniques exposure • Limited ability to• Accurate recovery of observe materials samples • Air rotary rigs not• Ability to sample at depth suitable for volatiles• Suitable for most ground conditions • Can cause preferential pathways for• Can be used for installing groundwater and gas contaminant migration, monitoring wells if not appropriately constructed
