Installing a vapor intrusion mitigation system is an important step toward reducing the movement of potentially harmful vapors into a building. However, installation alone does not guarantee that the system will continue working effectively.
Post-mitigation monitoring evaluates system performance after installation. Through pressure measurements, inspections, and environmental sampling, project teams can confirm that the mitigation strategy remains protective as building and subsurface conditions change.
Low flow groundwater sampling is designed to collect representative water samples while minimizing disturbance inside a monitoring well. Instead of rapidly removing several well volumes, technicians pump groundwater at a controlled rate that limits drawdown, reduces sediment mobilization, and helps preserve the sample’s natural chemistry.
Environmental contamination can happen below the surface in ways that are difficult to see, measure, or remove. Contaminants may move through groundwater, collect in soil pores, bind to organic matter, or remain trapped in low-permeability zones long after the original release. When that happens, cleanup teams need remediation methods that can reach the affected area without always excavating or removing large volumes of material.
That is where in situ remediation becomes especially important. In situ remediation treats contamination where it is found, directly in the subsurface. Instead of digging up soil or pumping all impacted groundwater to the surface for treatment, remediation professionals use biological, chemical, thermal, physical, or containment-based strategies to treat contaminants in place.
PVC well screens and casing are essential components in groundwater monitoring, environmental sampling, water wells, and drilling applications. The casing helps maintain the borehole's structure, while the well screen allows water to enter the well and helps reduce the movement of sand, sediment, and debris. Together, they support cleaner sampling, better well stability, and more reliable long-term performance.
When choosing PVC screen and casing, one of the most common decisions is whether to use Schedule 40 PVC or Schedule 80 PVC. Both are widely used, but they are designed for different installation conditions and performance needs.
How to Clean Well Water
Thursday, June 4, 2026
Clean well water starts with the right process. Whether you are dealing with cloudy water, mineral scale, iron buildup, bacteria concerns, low flow, or unpleasant taste and odor, cleaning a private well requires more than adding a quick chemical treatment. A properly maintained well system should be tested, cleaned, flushed, and disinfected using products designed for potable water applications and well construction materials.
Soil vapor extraction is one of the most widely used remediation methods for sites impacted by volatile organic compounds (VOCs), petroleum hydrocarbons, chlorinated solvents, and other vapor-forming contaminants. When contamination is present in unsaturated soil above the groundwater table, vapors can migrate through pore spaces, create vapor intrusion concerns, and complicate site closure. Soil vapor extraction, often shortened to SVE, helps remove those vapors by applying a vacuum to the subsurface and directing contaminated soil gas to an aboveground treatment system.
For environmental consultants, remediation contractors, and field technicians, successful SVE work depends on more than the blower or extraction well. The quality of the sampling network, tubing, valves, fittings, vapor points, and monitoring accessories all influence whether the system can be evaluated, optimized, and documented properly. That is why purpose-built vapor and gas sampling supplies are essential throughout investigation, pilot testing, system startup, and long-term performance monitoring.
Sub-slab soil gas sampling is one of the most important lines of evidence in vapor intrusion investigations. When volatile chemicals are present in soil or groundwater, vapors can migrate through the subsurface and enter buildings through cracks, joints, utility penetrations, and other openings in the slab. The Environmental Protection Agency (EPA) describes vapor intrusion as the migration of vapor-forming chemicals from subsurface sources into overlying buildings, and its guidance treats sub-slab data as a key part of evaluating whether the pathway is complete and whether occupants may be at risk.
Groundwater is one of the most important natural resources for drinking water, industrial use, agriculture, and environmental health. Yet it is also highly vulnerable to contamination from sediment infiltration, poor well construction, improper maintenance, chemical spills, and inadequate sampling practices.
Wisconsin’s new Vapor Intrusion Guidance (RR-800) is more than a state update; it is a signal that vapor intrusion programs are becoming more detailed, more building-specific, and more proactive. The guidance applies to sites where contaminated vapor has migrated – or could migrate – into current or future buildings, and it emphasizes investigation, immediate response, mitigation, and long-term stewardship as part of the cleanup process.
From groundwater purging to vapor intrusion assessments, the tubing you choose can make or break sample quality, data accuracy, and even how smoothly your day goes in the field.
There are typically two criteria to go by when selecting the right tubing for the job:
Material (compatibility, durability, chemical resistance, flexibility)
Size (OD for fittings + routing, ID for flow and purge times)
This guide walks through the “why” behind the common tubing materials, including best applications for each kind, and how to avoid the classic sizing mistakes that lead to leaks, poor flow, or compatibility problems.
