No detections of petroleum hydrocarbons <br />No detections of PCBs <br />Some PAH detections in DP-1 composite although the detections appear to be below <br />commercial/industrial health-based thresholds (DTSC HERO Note 3). It should be noted that <br />the concentration of Dibenz(a,h)anthracene was 43 ug/kg, which is above the residential <br />threshold of 28 ug/kg but below the commercial/industrial threshold of 310 ug/kg. <br />No SVOC detections, except for a couple of analytes in the sample from DP-1; analytes that <br />are common to both the PAH analysis (EPA 8270C SIM) and the SVOCs analysis (EPA 8270C). <br /> <br />I have a question about invoicing. Should we invoice the in-scope work directly to the City of <br />Riverbank pursuant to the contract we executed with the City? For the out-of-scope tasks <br />(permitting and permitting fee, the additional dioxin/furan and asbestos analysis) should we bill to <br />SitelogiQ or the City of Riverbank? <br /> <br />Thank you, <br /> <br />John Lane, PG <br />Condor EarthOffice: 209-938-1061 <br />Mobile: 209-743-7443 <br />jlane@condorearth.com <br /> <br />From: Nathan Gustus <nate.gustus@sitelogiq.com> <br />Sent: Monday, August 26, 2024 2:13 PM <br />To: John Lane <jlane@condorearth.com>; Luke Castle <lcastle@condorearth.com> <br />Subject: Re: Riverbank WWTP Soil Sampling <br /> <br />Ok, let's move forward with both. <br />Nathan​​​​ Gustus |Sr. Project Manager |M: 916.693.7140 <br />From: John Lane <jlane@condorearth.com> <br />Sent: Monday, August 26, 2024 2:02 PM <br />To: Luke Castle <lcastle@condorearth.com>; Nathan Gustus <nate.gustus@sitelogiq.com> <br />Subject: RE: Riverbank WWTP Soil Sampling <br /> <br />CAUTION: This is an external email.
