Latest Patents
One of George V Last's latest patents is titled "Method and apparatus for sampling low-yield wells." This invention provides an apparatus and method for collecting samples from low-yield wells or perched aquifers. The system includes a pump and a controller that responds to water level sensors, ensuring that the sample reservoir is filled efficiently. The controller activates the pump when the water level reaches a high level and deactivates it when the level drops, continuously cycling until the desired volume is achieved. Additionally, the system can purge an initial quantity of water before filling the reservoir, which can be located either inside or outside the well.
Another significant patent is "Methods and apparatuses for reagent delivery, reactive barrier formation, and pest control." This method involves positioning reagent delivery tubes in contact with soil, allowing for the diffusion of soil-modifying reagents. The tubes can be placed using directional drilling equipment and are designed to enhance soil nutrients, control pests, and form reactive barriers. The reagents can include various gases, liquids, colloids, and adsorbents that interact with soil components.
