The Carpinteria Valley and Montecito water districts (California) have received a $2.9 million settlement from engineering firm Penfield & Smith and the Cushman Contracting Corp. more than two years after a leak was discovered in the 21 million-gallon Ortega Ridge reservoir in which the two companies installed a four-acre aluminum cover in 2007. A leading plan for reservoir repair and use of the settlement money is the addition of a high-density polyethylene (HDPE) geomembrane liner.
