Split Core Sampler for Submerged Sediments
Superfund Innovative Technology Evaluation (SITE)
Environmental Technology Verification (ETV)
EPA/600/R-01/009
December 1999
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 (1) consistently collect a given volume of sediment,
(2) consistently collect sediment in a given depth interval, (3) collect
samples with consistent characteristics from a homogenous layer of sediment,
and (4) collect samples under a variety of site conditions. 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.
