Impact to Ground Water Update – Updated guidance and Spreadsheet for the Synthetic Precipitation Leaching Procedure
The technical guidance describing the use of the Synthetic Precipitation Leaching Procedure (SPLP) to determine site-specific impact to ground water remediation standards has been revised. The updated document, “Guidance for the use of the Synthetic Precipitation Leaching Procedure to Develop New Jersey Site-Specific Impact to Ground Water Remediation Standards” (version 2.0, April 2013) now allows the use of this procedure with volatile organic chemicals (VOCs). For these chemicals, modified sampling and extraction procedures should be used. Both the guidance document and updated NJDEP SPLP spreadsheet (version 3.0, April 2013) may be downloaded from the Remediation Standards website.
