Shell tested and evaluated several technologies to identify the most effective and safe technologies to treat soils within the Carousel Neighborhood.

Three methods of remediation will be used:

  1. Excavation
  2. Soil Vapor Extraction and Bioventing (SVE)
  3. Sub-Slab Depressurization (SSD)

These methods were approved by the Water Board to address the conditions in the neighborhood.

As part of the SVE system, a piping manifold is required to convert the multiple pipes throughout the tract into one main pipe. For more information, view the Manifold House Handout.

Electricity costs related to the SSD system will be reimbursed by Shell. For more information , please view the SSD Power Reimbursement Handout.
