Effectively Saturate a Treatment Zone

In order to create a successful bioamendment barrier in a traditional vertical remediation well design, the radius of influence must propagate far enough into the formation to overlap with the radius of influence of the adjacent wells in the barrier. Gaps in the amendment barrier provide conduits for contamination to seep through and continue downgradient.
Horizontal remediation wells provide continuity across the well screen during the injection process and ensure that the treatment zone is effectively saturated with the remedial amendment.
cross-section

Traditional in-situ bioremediation techniques, such as vertical well injections, often result in invasive designs and lengthy remediation timelines. Tens of injection wells, or more, may be required in order to inject the proposed amendment volume. One horizontal remediation well can often replace several vertical wells in order to remediate the same target area, eliminating unnecessary additional well construction in the subsurface and obstructive well vaults at the surface.

Source-area contamination is often difficult to reach, and without intercepting the proper preferential pathways vertical wells can struggle with delivering the full amendment volume. If time and efficiency are important factors when applying bioremediation at your site, horizontal remediation wells are the preferred method to achieve your project goals.
