Story of a Photo: Geomembrane Integrity Survey from a Crane
While nosing around in Geosynthetica's archives, we happened upon an interesting photo (dated 2004) of Ian Peggs conducting a liner integrity survey while suspended from a crane. Though liner integrity surveys are common, the conditions in which they must be conducted vary wildly. We asked Dr. Peggs if he might offer a few notes about this particular situation. Here's what he shared with us. Read more.
Upgrading Wastewater Treatment at a Marlborough Winery
