GROUNDWATER MULTILAYER SAMPLING SYSTEM

Company & Technical Background

The company is providing products and solutions of flexible liner technology to the field of underground measurement. As a highly innovative technology company, the company's products in the field of underground measurement technology has many patents: over 20 in the United States, and 13 in other countries. Through flexible liner and related technologies, we could solve problems in water quality, hydraulic gradient, pollutant analysis, permeability distribution, hydrological condition monitoring, etc.

Most of the application technologies include surveying contaminated sites within polluted areas. In the United States, there are 48 state venues applied to flexible liner technology, the main users cover over 40 majors of companies, enterprises, and environmental protection departments. Internationally, major clients of technologies such as Canada, Japan, Denmark, France, the United Kingdom, Israel, Australia, South Korea, South Africa, Germany, Brazil, and Spain include the US Environmental Engineers, Boeing, Ford, GM, Exxon Mobil and so on.

The general characteristics

  • • Quickly emplaced from a shipping reel by eversion into the borehole.
  • • Seals the entire borehole with a pressurized flexible liner of polyurethane coated Nylon fabric. The sealing pressure is provided by excess water head in the liner.
  • • Defines the sampling interval for each port with an exterior permeable surround called a "spacer."

    • The general characteristics

  • • Multi-level ground water sampling
  • • Mapping hydraulic head distribution
  • • Draws the pore liquid into the central pumping system directly from the formation.

    • The general characteristics

    • Allows the water level for each port to be tagged from the surface and can be provided with recording pressure transducers for each port.
    • Provides 1-2 gals, typically, from each port per stroke.
    • All ports can be purged and sampled simultaneously.
    • Is relatively easy to remove for repairs, replacement, etc…
