Leeching Concrete?

Concrete Leeching into groundwater?

Concrete is one of the most common materials used in present day construction.  Just like most homes and buildings, wind turbines are anchored into a concrete foundation. 

Check out this article on testimony made by environmental experts on cement leeching:

“Concrete is used in construction of drinking water facilities, dams, bridges, and fish holding tanks without adverse environmental effects.”

We think the best way to address this concern of concrete leeching for Lighthouse is to explain some of the very extensive activities performed during the permitting process.   Water resources are protected by very strict federal and state regulations.  These regulations are present in the Article 10 application and well known by the construction contractors that perform the development activities. 

The Article 10 application requires Lighthouse Wind to study:

  • the existing environmental conditions (site characterization),
  • explain in detail how the project would impact any of the existing environmental conditions, and
  • how the Project will mitigate those impacts, which includes a list of Best Management Practices (BMPs) to be followed during construction and operation of the wind farm. 

The Project’s Site Characterization is defined by studying the following:

-          Soils, Geology

-          Wildlife

-          Water Resources, Wetlands

-          Cultural Resources

-          Land Use

-          Acoustics

-          Visual

-          Transportation

-          Socioeconomic

Site characterization helps to develop what proposed BMPs would be most successful for the Project area.  The in-depth geotechnical engineering and hydrology studies performed during site characterization would determine drainage patterns, vegetation, erosion potential, and surface water.  This information would contribute to the development of the BMPs used during turbine foundation construction, such as only cleaning concrete trucks in designated, approved areas.

Once we study the existing environmental conditions of the project area and have considered all of the setbacks (from homes, roads, building, etc), then we can start to determine turbine placement.  

As you can see, a lot of studies and strategic work needs to take place before any turbines can be sited into a draft layout.   Thoughtful placement of every turbine is a priority to us and we hope this opens the door to have more discussions about all of our ongoing and upcoming studies.
