U.S. MIDWEST - A series of depth of cover analyses were performed for 11 different large river/lake crossing sites across the midwest United States during the months of April through July. Each river crossing consisted of two to three line-crossings per site. DoC Mapping utilized electromagnetic locating sensors, multibeam sonar, and side scan sonar in unison, resulting in one of our best data-set packages to date!

WISCONSIN - A depth of cover analysis was performed last month on a large section of the Lower Fox River in Green Bay, WI. 17 utilities crossing under the Fox River were located in 12 days!

The Fox River has been undergoing a massive cleanup that is designed to reduce risk to human health and the environment due to the presence of PCBs in the Fox River sediment. It's a multi-year cleanup effort that includes dredging, capping and covering over a 13-mile stretch of the Lower Fox River. The project officially started with dredging and processing on April 28, 2009.

Our role in locating these utilities this last spring, was in preparation for all dredging operations within the areas where they exist. Below are a few videos and photos from DoC Mapping's time on this project.

NEW JERSEY - A depth of cover analysis was completed on 2 electrical conduits from levee to waterline on each bank of the Elizabeth River in New Jersey. DoC Mapping utilized their robust Land Sensor Suite for this project. This equipment suite can also be mounted to various all-terrain vehicles in order to collect data for hundreds of miles through pipeline and utiliy Right-of-Ways!
