Text Box: The NJDEP proposed new groundwater standards in the October 4, 2004 issue of the New Jersey Register.  Corrections to the rule proposal appeared in the November 15, 2004 issue of the New Jersey Register.  The basis and background document for the proposal along with a complete copy of the proposal can be found in PDF format on the NJDEP’s website at http://www.state.nj.us/dep/.   Some notable changes, both increases and decreases, which could affect sites at Picatinny

 are listed below in units of micrograms per liter (ug/L):


Constituent                          Current Standard             Proposed Standard         

Acetone                                       700                                          6,000

Ammonia (total)                       200                                            3,000

Arsenic (total)                               8                                                    3

Beryllium                                     20                                                    1

Carbon tetrachloride                    2                                                    1

Chloroform                                   6                                                   70

Chromium (total)                     100                                                  70

Lead (total)                                  10                                                     5

Text Box: Sodium lactate was introduced into injection wells as part of a pilot study aimed to accelerate degradation of dichloroethene and vinyl chloride at Site 78.  Lactate was selected for this site because it dissipates relatively quickly; there was concern that other more long-lived electron donor compounds such as HRC could impact nearby,                             Text Box: The Record of Decision (ROD)for Area D was the subject of public notice in Morris County papers on September 31, 2004.    No comments were received and the existing ROD remained unchanged.  The Army Corps of Engineers is expected to award a contract for the work by the end of April 2005.  The Area D remedial project is funded for this fiscal year.

Text Box: Impact of Newly Proposed NJDEP Soil Remediation Standards on Picatinny Environmental Cleanup
Text Box: The NJDEP proposed sweeping revisions of the soil remediation standards in the July 19, 2004 New Jersey Register. Existing NJDEP regulations stipulate that previously  remediated sites must be revisited when new standards are enacted. If the newly enacted standards differ by an order of magnitude from pre-existing standards, then  
Text Box: the  site can be re-opened by the NJDEP.  In those cases the NJDEP can hold the responsible party to the more stringent standard.  At present few sites have actually progressed far enough that cleanup can be considered complete. However, there are many sites where the investigation stage has been completed and various
