If <br /> any of the development/purge water generated during field activities is generally free of <br /> particulates , this water will be treated by the on-site P&T system and not staged in drums . <br /> Waste characterization sampling and analysis will be performed consisteni with IDW <br /> activities performed during previous contaminant assessment phases of work at the site. <br /> Two composite samples will be collected from the drums containing drill cutt ngs . These <br /> two samples will be submitted to US BioSystems for analysis by Toxicity Qlaracteristic <br /> Leaching Procedure (TCLP) for Resource Conservation and Recovery Act (RCRA) metals, <br /> VOCs (EPA Method 8260) , and semi-volatile organic compounds (EPA Method 8270) . <br /> The costs for laboratory analysis of the TCLP samples has not been included herein since it <br /> is anticipated that the laboratory analytical charges will be directly billed to IRC by US <br /> BioSystems . The analytical results will be used to assess whether or not the IDW is <br /> characteristically hazardous and to evaluate appropriate disposal options . These drums will <br /> be marked as indicated earlier, placed on wood pallets, and stored at an on-site location <br /> designated by the SWDD . Any transport and disposal of wastes from the site will be <br /> arranged by the SWDD . If so requested, GeoSyntec can provide assistance with IDW <br /> disposal (meeting IRC staff, coordinating drum removal , etc . ) ; however, no budget is <br /> included for IDW disposal assistance . <br /> In addition, under Subtask 2 . 2 , budget has been included to repair hurricane damage to <br /> the pump and treat system, including purchase and installation of: (i) totalizers or recovery <br /> wells RW- 1 and RW-2 ; and (ii) a blower intake housing unit . <br /> Task 2. 3 Well Redevelopment <br /> A review of data associated with monitoring wells installed and sampled a part of the <br /> Targeted Brownfield Assessment (TBA) grant revealed that a number of wel s exhibited <br /> turbidities of greater than 1 , 000 nephelometric turbidity units (NTUs) . Elevat d turbidity <br /> readings may result in elevated detections of groundwater analytes . As reques led by IRC , <br /> this proposal includes labor and equipment for GeoSyntec to redevelop th following <br /> existing monitoring wells in an effort to remove fine-grained particles from the well casing <br /> and reduce the turbidity to acceptable levels (generally less than 20 NTUs) : G -MW24A, <br /> GR-MW24B , GR-MW26B , GR-MW27A, and GR-MW27B . The wells will be <br /> redeveloped by overpumping and surging.
