Gas Vapor Probe (GVP) Kits utilize a slide hammer or an electric combination rotary hammer drill along with GVP extensions to insert our stainless steel GVP tips to the desired sampling point. Before driving GVP tips, please ensure that the Fluoropolymer tubing is properly connected to the barbed fitting for convenient sampling.
Choose from our selection of two GVP tips specifically designed for our GVP Kits – GVP Dedicated Tips and GVP Retract-A-Tips.
GVP Dedicated Tips are strategically installed as permanent disposable sampling points. They serve the purpose of investigating hydrocarbon spills, underground storage tank and pipe leaks, landfill contamination, and hazardous waste.
GVP Retract-A-Tips are inserted into the soil and then opened for sample extraction. Due to their design, equilibrium time is reduced from final installation to sampling. In addition to their innovative design, Retract-A-Tips offer the incredible advantage of being easily decontaminated and ready for reuse at the next sampling point. They can also be used for shallow groundwater sampling.

From Pans to Buoys: Advancing Reservoir Evaporation Rate Monitoring in Texas
In warmer climates like Texas, high reservoir evaporation rates can lead to declines in water level and water availability during droughts, making monitoring essential in order to ensure water security during times of scarcity. 
 
According to the Texas Water Development Board (TWDB), evaporation rates in Texas were previously based on data collected from a sparse network of Class A evaporation stations, dating back to the 1960s. These pans were stationed near reservoirs and still remain a widely accepted standardized approach to measuring evaporation rates on land. 
 
Monthly pan-to-lake coefficients were developed in the 1980s to connect the data collected from the pans to known lake conditions, extrapolating evaporation rates of the lakes using the pan data.

The United Kingdom has grappled with wastewater management problems for decades. Although sewage treatment in the 20th century allowed many rivers, including the tidal Thames, to have healthy fish populations, combined sewer overflows into rivers–most commonly during heavy rainfall–affected water quality and occasionally even killed fish. 
 
Problems reached a head in 2012 when multiple infractions of European urban wastewater treatment laws threatened costly fines, on top of the environmental cost of repeated sewage spills into British rivers. 
 
Fast forward to 2025, and after a decade of construction work, London’s Thames Tideway Tunnel , affectionately dubbed the “super sewer”, is now fully activated and ready for testing.

In one history, Whangārei Harbor, nestled in the lush hills of New Zealand’s North Island, gets its name from the Māori, “waiting for the breastbone of the whale.” It seems fitting, then, that it’s now home to state-of-the-art acoustic monitoring buoys listening for marine mammals around the clock. 
 
In September 2024, a team from Auckland-based underwater acoustics firm Cetaware Ltd installed NexSens buoys in Northport, a major commercial port at the entrance to the Whangārei Harbor. 
 
The first buoys to be installed by Cetaware in a permanent setting running 24/7, they use real-time artificial intelligence (AI) models to passively sense Delphinidae–from common dolphins to orcas.
