Why are those wells for?
• CPT (Cone Penetrating Testing) – method used to provide soil properties and delineating soil stratigraphy(6 wells)
• Recovery Wells – Used for Extraction LNAPL (Light Non-Aqueous Phase Liquid) and Groudwater (88 wells)
• Observation Wells – Used for gauging only (85 wells• Monitoring Wells – Used for Gauging and Sampling
(24 wells)
