Water Treatment

Opal's geologists and engineers develop and implement water monitoring programs in complex settings to define and characterize hydrogeologic regimes. The ground water models are limited to specific analytes to most appropriately illustrate migration and to develop cost-effective water restoration plans. Ground and surface water restoration may involve active water extraction and treatment using a variety of equipment trains, or may incorporate passive systems such as slurry trench barrier walls or interception trenches.
