i <br /> Page 51 and Appendix D (pg A-18) of the LUFT Manual describe the <br /> analytical tests that are required along with'� the detection ` <br /> ' limits required under Department of Health Services (DHS) j <br /> protocol for all soil and -groundwater samples:. <br /> t <br /> All work and reports which require geologic or engineering <br /> evaluations and/or judgements must be performed under the <br /> ' direction of an appropriately registered or certified <br /> professional (Sections 6735 , 7835, and 78:35 . 111of the Business and <br /> Professional Code) . Much of the investiga}tivej1work required at <br /> your site will require the usage of the r:egistered professional . <br /> Quarterly monitoring and groundwater samp:linglare required at <br /> your site and as such is considered "reimbursable" from the State <br /> Cleanup Fund. Technical procedures utilized in obtaining these <br /> samples are very important and in order t'o avoid volatization, 4 <br /> cross-contamination, or sample degregation, and PHS-EHD � <br /> recommends that you do not obtain the grorundwiater samples <br /> yourself . Improperly obtained samples, sample's without accurate <br /> chain of custody documentation, and samples not properly <br /> preserved will not be accepted by PHS-EHD ar41the sampling event <br /> will be considered invalid and must be repeated. <br /> All field activities on this site (ie . , sampling, drilling or hand <br /> augers, and over-excavation) shall be under the witness of an <br /> authorized representative of PHS-EHD. Pl' ase;[ contact me at least <br /> 48 hours in advance to set up all of your appointments for your <br /> witnessed field activities . <br /> Please be advised that argumentative discussions are an I <br /> unacceptable delay in the investigative process of your site and <br /> the related expenses for generating letters aired responding to <br /> such arguments are not reimbursable costslfron the Cleanup Fund. <br /> Past directives issued to you for workplan submittal , quarterly , <br /> monitoring and sampling of the only monitoring well on site, and <br /> a schedule of dates these activities shall begin are still in <br /> effect . PHS-ERD hereby modifies the orifi nal'!� directive due date <br /> to the following; <br /> -The monitoring and sampling of the well. site shall be <br /> conducted during this fourth quarter,) (Oct. Nov. and Dec <br /> 1994) and the report of findings is due during January 1995 . <br /> -A workplan to investigate the lateral limits of your soil <br /> and groundwater plume and provide site groundwater gradient <br /> direction shall now be submitted by �January 16, 1995 . <br /> Currently, no requirement exists that dictates a registered <br /> professional must complete a workplan proposal or quarterly <br /> monitoring report . Until a gradient direction can be determined <br /> from multiple monitoring wells and a professional judgement is <br /> required, you may submit workplans and sampling/monitoring <br /> reports . The guidance documents mentione& bo" e list the required <br /> inclusions to these submittals . <br />
