Where can I find information on sampling groundwater?
Guidance on groundwater sampling can be found in EPA's "RCRA Groundwater Monitoring: Draft Technical Guidance" published by the Office of Resource Conservation and Recovery (ORCR), EPA/530/R-93/001, NTIS PB 93-139350, www3.epa.gov/epawaste/hazard/correctiveaction/resources/guidance/sitechar/gwmonitr/rcra_gw.pdf.
