Innovative Ground-Water Remediation

EnviroTrac developed the Well Stripper, a patent-pending innovative ground-water remediation technology. The Well Stripper is an in-situ well stripping and recirculation technology that provides a cost-effective alternative to traditional pump and treat methods. The Well Stripper has been used successfully at numerous sites in the northeast and can treat common volatile organic compounds (VOCs) such as chlorinated solvents (TCE and PCE) and petroleum hydrocarbons (BTEX and MTBE). As a by-product, the Well Stripper aerates and increases dissolved oxygen concentrations in ground water, which enhances biodegradation.

No Purge vs. Purge Well Sampling

EnviroTrac was the first to challenge well purging procedures that are now accepted industry-wide. EnviroTrac teamed up with Shell Oil and completed several studies to determine the efficacy and accuracy of no-purge sampling versus the standard well-sampling protocol that requires the purging of three well-bore volumes of water prior to collecting samples for VOC analysis. These studies clearly showed that there were no statistically significant differences in analytical results for ground-water samples collected from the same wells by both sampling methods. EnviroTrac's studies were compiled in an American Petroleum Institute (API) bulletin. Based upon these studies, EnviroTrac has received approval from state agencies to collect ground-water samples from petroleum-release sites utilizing the no-purge sampling methodology. This procedure allows for a significant cost savings to our clients in time and equipment costs as well as not generating well-purge water that requires containerization, management and disposal.
