With a 2015 PTT Grant, Eric Liefeld from Mesilla Valley Preservation, Inc. will lead a team to test and validate a cost-effective and minimally-invasive field kit for rapidly detecting and measuring salt loads in earthen walls.  Salt attack (salt weathering) and rising damp are common yet often misunderstood problems affecting historic masonry structures in the Mesilla Valley in Southern New Mexico, and elsewhere. While adobe structures are strongly affected by this problem, they also offer compelling opportunities in the detection and removal of salt loads.  The field kit and methodology under development are innovative because they use new technology and a novel approach to give field preservationists an economical and easy approach to rapidly assess salt issues in the field in walls, soils, and new materials.
