Even the most attractive scene can harbour a range of significant contaminant sources.  This site contained an arsenic hotspot from an old sheep dip, two underground petrol tanks, a burial site for the remains of the sheep dip, a farm dump, two diesel tanks, a lubricant store, and lead hotspots from lead paint.  If treated appropriately all of these can be effectively managed, remediated or isolated once identified and located without significantly impacting on the value of the development.
