Ms. Ann Kolata April 4, 2011 SB1067.400.0001 Page 3 and intermediate groundwater samples will then be completed as described above. Between each of the sampling locations, the drilling rods and well screen will be decontaminated by washing with Alconox and water solution and rinsing with deionized water. The following sample quantities (including trip blanks, matrix spike /matrix spike duplicates, duplicates, and field blanks) and laboratory analyses are proposed: 1. Up to 105 samples for VOCs in accordance with U.S. EPA Method 8260; 2. Up to 27 samples for SVOCs in accordance with U.S. EPA Method 8270/8270 SIM; 3. Up to 23 samples for total RCRA metals in accordance with U.S. EPA Method 6010/7470; 4. Up to 23 samples for dissolved RCRA metals in accordance with U.S. EPA Method 6010/7470; and 5. Up to 21 samples for PCBs in accordance with U.S. EPA Method 8082. Duplicate samples will be collected at randomly selected monitoring well locations. Field /equipment blanks will also be collected and submitted along with a trip blank for analysis as part of quality assurance /quality control (QA/QC) of field procedures. Purge and decontamination waters will be collected and stored in U.S. DOT - approved 55- gallon drums. As described above, drill cuttings, excess samples, purge water and decontamination water will be drummed and staged at a location on -Site acceptable to the Client. Costs to remove, transport, and dispose of approximately 12 55- gallon drums of containerized groundwater and drill cuttings (which are presumed to be non - hazardous) are included in this task. Following receipt of laboratory results, Hull will immediately evaluate the distribution of COCs in groundwater and present the City with a proposal to install a permanent monitoring well network on- and off -Site. A final report documenting this stage of work will be prepared with the separate letter report documenting installation of the monitoring well network in May 2012. SCHEDULE Hull has tentatively scheduled the initial work (e.g., surveying, utility locates, etc.) for the temporary groundwater sampling event to begin on or about April 11, 2012 subject to your approval of this proposal. Temporary sampling point installation is scheduled to begin April 16, 2012. We anticipate all drilling and sampling activities, and laboratory analyses, will be completed by April 27, 2012, and will immediately prepare a proposal for monitoring well installation by Wednesday, May 2 for consideration at the May 8 Redevelopment Commission meeting. This schedule will allow for completion of the RWP by June 30, 2012 in accordance with the schedule you have proposed to IDEM. COMPENSATION A breakdown of costs is attached as Table 1. The fees have been developed based on our estimate of hours for each labor category expected to be involved in the project. The project will be billed on a four -week basis with payment due to Hull within thirty days after receipt of an invoice.
