Lancaster County engineering firm Rettew Associates Inc. has acquired Enviroscan, a Lancaster-based geophysics company.
Manor Township-based Rettew, which recently opened new offices, said it finalized the deal on Monday.
Enviroscan’s team will operate under the Rettew brand name and work from the company’s headquarters at 3020 Columbia Ave. Enviroscan, a woman-owned firm, was founded in 1992.
Geophysics is the science of detecting and mapping hidden underground or underwater objects and features.
Rettew said acquiring Enviroscan will boost its existing earth sciences services, which include geotechnical, environmental, water resources and subsurface utility engineering investigations.
Terms of the deal were not disclosed.
