Draft RI/FS scoping plan - August 16, 2004
After a site is listed on the NPL, a remedial investigation/feasibility study (RI/FS) is performed at the site. The remedial investigation serves as the mechanism for collecting data to:
- characterize site conditions;
- determine the nature of the waste;
- assess risk to human health and the environment; and
- conduct treatability testing to evaluate the potential performance and cost of the treatment technologies that are being considered.
- Read more about RI/FS.
