Table of Questions

What is your primary job function?

Name of State or Federal Regulatory Program with which you are associated.
3.
Incremental sampling is the same as conventional composite sampling.
4.
The decision unit (or sampling unit) used in incremental sampling is site-specific.
5.
Incremental sampling is generally more expensive than conventional discrete sampling.
6.
Incremental sampling results are more representative of the sampled area than those from discrete samples.
7.
Incremental samples commonly require additional laboratory sample preparation.
8.
Incremental sampling is ineffective because it cannot identify specific areas of high contamination.
9.
The use of incremental sampling for soil sampling is widespread.
10.
Incremental sampling cannot be used for risk assessment because it does not address variability.
11.
When sampling soil, the contaminant concentration will depend upon the amount of soil sample analyzed.
12.
When sampling and analyzing soil, the sampling error is generally much greater than the analytical error.
13.
