& Supply, Inc. Split Core Sampler for Submerged Sediments
The Split Core Sampler for Submerged Sediments (Split Core Sampler) designed and fabricated by Art's Manufacturing & Supply, Inc., was demonstrated under the U.S. Environmental Protection Agency (EPA) Superfund Innovative Technology Evaluation Program in April and May 1999 at sites in EPA Regions 1 and 5, respectively. In addition to assessing ease of sampler operation, key objectives of the demonstration included evaluating the sampler's ability to:
This report describes the demonstration results for the Split Core Sampler and two conventional samplers (the Hand Corer and Vibrocorer) used as reference samplers. During the demonstration, the Split Core Sampler performed as well as or better than the reference samplers. Based on visual observations, both the Split Core Sampler and reference samplers collected partially compressed samples of consolidated and unconsolidated sediments from the sediment surface downward; sample representativeness may be questionable because of core shortening and core compression. Sediment stratification was preserved for both consolidated and unconsolidated sediment samples collected by the Split Core Sampler and reference samplers. No sampler was able to collect samples in the deep depth interval (4 to 11 feet below sediment surface). The average sampling time was less for the Split Core Sampler than for the reference samplers. Sampling costs for the Split Core Sampler were 8 percent greater than those for the Hand Corer and 95 percent less than those for the Vibrocorer.
