A common scope of work for ReRem Equipment Corp is the sparge & vent pilot-study. Baseline data typically includes headspace VOC’s, depth to water (DTW), dissolved oxygen (DO) and areal distances. A stepped vacuum is applied to the formation with resultant flow, VOC concentrations and induced vacuum at surrounding wells recorded. Stepped air-sparge is then introduced. Data-set collection is client-specified, and commonly includes DTW, DO, and / or inert tracer gases.
We usually provide SVE skid with VFD controller, sparge compressor, generator, interconnect hoses & wellhead adapters, and equipment operator (on-site assistant). The client (consultant) provides HASP, site-specific instruments, waste containment or carbon beds, SOP with data sheets and qualified personnel.
Typical costs for a 10-hour test, including equipment & operator is $1400. This excludes mobilization and perdiem from Albany, NY.
