The New England Branch Designs an Off-grid Water Supply for a School in Rural Liberia

2026-09-25T09:06:40-06:00June 21st, 2016|Tags: , , , , , , , |

In Spring 2014, a group of volunteers from Geosyntec’s New England Branch began designing an off-grid water supply system for a school in rural Liberia. The project arose through the vision of a group of Liberian refugees who had relocated to Providence, Rhode Island and wanted to build a school near the village they had to leave behind during the Liberian Civil War.

Geosyntec is an industry leader in remediating difficult-to-treat environmental impacts to soil, groundwater, and sediments through the use of specialized in situ techniques. Our practitioners are adept at expediting site investigations, optimizing remediation solutions, and accelerating site closure through a wide range of innovative technology applications. Our expertise in the implementation of new, emerging, and conventional technologies allows our practitioners to frequently bridge the gap between the development and first-to-field stages of environmental solutions. Our expertise and industry leadership in the advanced application of microbiology-based solutions for the remediation of recalcitrant contaminants in soil and groundwater has established Geosyntec’s solutions as the preferred method, especially for sites with proven resistant to conventional remediation technologies or when compared to the comparatively high costs for the application of physical and chemical technologies that achieve similar results. Two of Geosyntec’s affiliated companies provide specialized services and technologies regarding in situ treatments:

Geosyntec’s expertise in efficient site characterization, including sites that exhibit complex groundwater-flow regimes, has distinguished our firm as a leader in groundwater assessment and groundwater remediation. Our practitioners address a broad suite of contaminants, including metals, chlorinated organic chemicals, petroleum hydrocarbons, and emerging contaminants, and use award-winning, technology-based remediation strategies that are often first-to-field. Many of our hydrogeologists specialize in modeling the fate and transport of contaminants through the most difficult types of media, including fractured and karst bedrock.
