Frequently Asked Questions (FAQ)
General Questions
Q: What does Vista GeoScience do?
A: Vista GeoScience provides advanced subsurface investigation and remediation contracting services. We specialize in environmental and geotechnical drilling, high-resolution site characterization (HRSC), and in-situ remediation technologies that help clients clean up contaminated soil and groundwater.
Q: Where is Vista GeoScience located, and do you work nationwide?
A: Our main office is in Golden, Colorado, yet we mobilize across the USA for environmental, industrial, and federal projects. We frequently support consulting engineers and remediation firms nationwide.
Q: How do I request a proposal or quote?
A: Visit our Contact Us page and complete the Request for Proposal form. Include site location, contaminant type, and required services—our technical team will respond quickly with a scope and estimate.
Q: What safety certifications do your field staff hold?
A: All field staff maintain OSHA 40-hour HAZWOPER training, medical clearance, and annual refreshers. Additional certifications include confined-space entry, first aid/CPR, forklift, and heavy equipment operation.
Q: What sets Vista GeoScience apart from other drilling or remediation contractors?
A: We combine specialized equipment, experienced field crews, and real-time digital data collection. Our integrated HRSC and injection systems allow for efficient, data-driven remediation solutions tailored to each site.
Site Characterization
Q: What is High-Resolution Site Characterization (HRSC)?
A: HRSC uses direct-push tools like Membrane Interface Probe (MIP), Optical Image Profiler (OIP), and Hydraulic Profiling Tool (HPT) to measure subsurface contamination in real time. These tools generate continuous vertical profiles, helping define contaminant mass and migration pathways more accurately than traditional sampling.
Q: What’s the difference between MIP, OIP, and HPT?
A: The MIP detects volatile compounds, the OIP identifies non-aqueous phase liquids (NAPL) using ultraviolet (UV) fluorescence, and the HPT measures formation permeability. Used together, they create a detailed 3-D picture of site conditions.
Q: How deep can Vista Geoscience direct-push systems reach?
A: Our rigs can typically reach depths up to 100 feet in most soil, depending on lithology. For deeper or harder formations, we use sonic or hollow-stem auger methods.
Q: Can Vista Geoscience collect soil and groundwater samples during profiling?
A: Yes. We can integrate discrete soil, groundwater, and soil gas sampling during HRSC to correlate field data with laboratory analytical results.
Q: How quickly can clients access data after drilling?
A: We provide real-time electronic data capture and often deliver interpreted logs and visualizations within 1–2 business days.
In-Situ Remediation
Q: What contaminants can your in-situ treatments address?
A: We treat petroleum hydrocarbons, chlorinated solvents (CVOCs), Per- and polyfluoroalkyl substances (PFAS), dissolved metals, and other recalcitrant compounds using oxidants, reductants, biological amendments, and sorption-based remedies.
Q: How do you select the right reagent or technology for a site?
A: Our team reviews historical data, site lithology, and contaminant chemistry to recommend proven and patented reagents. We have long working relationships with remediation design consultants to provide off the shelf reagents or design help. Bench and/or Pilot testing is recommended before full-scale application confirm performance.
Q: Can in-situ injections work in low-permeability or fractured rock?
A: Yes. We use pneumatic and hydraulic fracturing to improve reagent distribution in tight soil and bedrock, ensuring contact with contaminants in difficult formations.
Q: What’s the difference between ISCO, ISCR, and bioremediation?
A: ISCO (in-situ chemical oxidation) breaks down contaminants quickly using oxidants; ISCR (in-situ chemical reduction) uses reductants to detoxify compounds; bioremediation enhances natural microbial activity for sustainable cleanup. We often combine these techniques for best results.
Q: Do you provide pilot testing before full-scale remediation?
A: Yes. Pilot testing allows us to evaluate reagent performance, delivery pressures, and treatment radius, optimizing full-scale design and cost efficiency.
Bedrock Fracturing & Injection Delivery
Q: What is hydraulic fracturing for remediation?
A: Hydraulic fracturing creates controlled fractures in low-permeability soil or rock to improve reagent distribution and permeability. It’s a proven way to reach contaminants that are otherwise inaccessible.
Q: How do you control the direction and spacing of fractures?
A: We use precise pressure monitoring and real-time feedback to manage fracture propagation. We also use confirmation coring, and performance monitoring wells points. Data from each interval ensures predictable spacing and vertical separation between fracture sets.
Q: Is bedrock fracturing safe?
A: Yes. Our procedures are carefully engineered, monitored, and documented. Fracturing pressures are kept below regulatory limits, and we use approved, environmentally safe materials.
Webinars & Training
Q: Are Vista GeoScience webinars free to attend?
A: Yes. Our webinar series are free and designed for environmental professionals. Each session covers practical topics on site characterization, injection design, or emerging contaminants.
Q: Will I receive a certificate of attendance?
A: Yes. Attendees receive a digital certificate that can be used toward continuing education or professional development hours (PDHs).
Q: Where can I find past webinar recordings?
A: Visit our Webinars page to access recordings, slides, and related resources from past sessions, or contact us for more information.
