CCAMP ENHANCED GROUNDWATER PROTECTION IN LANDFILL PROGRAMS RECOMMENDATIONS 



December 1986 Page 1-5 



sites since so many of the state's present landfills are located in 

 unacceptable sites by current standards. A site evaluation, as de- 

 scribed in recommendation #11, should be required. 



MONITORING 



17. Existing groundwater monitoring handbooks (DWS and DSHW each have one) 

 should be recognized and required to be standard operating procedure. 

 These handbooks are consistent with each other and have already been 

 reviewed. Comprehensive guidelines for monitoring and sampling proce- 

 dures are being developed by DEQE and will be utilized department 

 wide, once completed. 



18. DSHW should review the installation plans for existing monitoring 

 wells on a priority basis using the previously mentioned ranking sys- 

 tem. Any of the older wells which may have deteriorated should be 

 closed and replaced, if necessary. Existing landfill monitoring sys- 

 tems should be revised based on this review. 



19. DEQE should establish a standard procedure detailing the following 

 aspects of a landfill monitoring program: hydrogeological investiga- 

 tion and field reconnaissance, field verification of flow regime, 

 monitoring well placement, well drilling development techniques, well 

 construction, sampling apparatus, frequency of sampling, sampling 

 protocol, treatment and handling procedures, list of parameters, sta- 

 tistical analysis of data, where data will be sent, and who will be 

 notified once standards are exceeded. DEQE should review the above 

 activities . 



20. A detailed protocol for the sampling program and chain of custody 

 should be established when initiating any monitoring program. Informa- 

 tion on this protocol should be contained in the DSHW regional files. 

 Any deviations from the established protocol should be clearly noted 

 by the person taking the samples . 



21. DWS should provide DSHW with a list of the landfills in Zone II of 

 public-water supplies. DSHW should then request DWS input on groundwa- 

 ter monitoring requirements in these zones. Copies of monitoring 

 results in Zone II should be sent to DWS. 



22. DWS should review current monitoring parameters to determine if they 

 are sufficient. DSHW should require monitoring for VOCs on a regular 

 basis . 



23. We support DSHW's policy that all new landfills should be required to 

 institute an adequate groundwater monitoring program subject to DEQE 

 approval. DEQE counsel should determine what additional legal authori- 

 ty is necessary, if any, for DEQE to require the initiation of a 

 groundwater-monitoring program (or the enhancement of an existing one) 

 at existing sites other than those applying for expansions.
