The Blackshare Difference

A consulting company is only as good as its people. And Blackshare takes great pride in its people. The Blackshare team is comprised of professional engineers, biologists, chemists, geologists, hydrogeologists, and safety specialists.
Beyond their exceptional qualifications, the members of the Blackshare staff are effective communicators - an essential tool in dealing with the varying requirements and specific goals of a drivers client base. The Backshare team identifies the needs of the client before the project is undertaken by listening to the client first and then maintaining a sharp focus on the objectives throughout the project. Qualified, experienced, and responsive people all rolled into one company - that's the Blackshare difference.

The Blackshare Approach

Environmental and safety projects vary greatly. Yet neither the size nor the complexity affects Blackshare determination and commitment to success. From the Phase I environmental site assessment (ESA) on an undeveloped parcel to complicated industrial site remedial investigations and feasibility study (RI/FS), Blackshare matches its best resources with the challenges presented by the project.
Blackshare is accustomed to playing varying roles for its clients. The company may be called upon for a single task such as a storm water or air permit for one client, while another will use Blackshare as its in-house environmental and/or safety staff to assume responsibility for all day to day compliance issues. Blackshare has the capability and flexibility to manage an entire project or provide staff to assist projects actively managed by the client.
Environmental and safety issues have a dual bottom line: compliance and risk tolerance. Clients know that in bringing them into and maintaining compliance, Blackshare fully exploress all options and recommends those that make the most economic sense.
