Operable Unit 2Task 4 Well Installations

MW95-ML9

Drilling of the deep bedrock borehole (designated MW95-ML9) as described in the September 30 1994 Field Sampling Plan for OU2Task 4 (FSP) commenced on February 10 Drilling activities were hampered by difficult weather conditions the highly fractured nature of the shallow bedrock in this area and down time caused by equipment failure The bedrock at this location was not self supporting to a depth of approximately 73 feet due to sever fracturing and weathering GZA discussed possible options with EPA including abandoning the borehole relocating the borehole or attempting to continue at this location The hydraulic conductivity and bedrock conditions observed in this boring and others in close proximity to it suggest that it is a very favorable location for potential leachate migration For this reason EPA saw no justification for abandoning or relocating the hole although the cost of continued drilling was much greater than anticipated due to these conditions

To allow continued advancement of MW95-ML9 the 10-inch casing was drilled to 57 feet below ground surface and 6-inch casing was telescoped into more competent bedrock at 825 feet below ground surface The boring was drilled open borehole using a 6-inch air hammer to a final depth of approximately 311 feet below ground surface (0 feet Mean Sea Level) The drilling was completed on February 21 1995 and the contractor demobilized the Barber Dual-Rotary Drilling Rig on February 22 1995

A draft boring log for this hole is provided in Attachment A

Other Boreholes

Boring MW95-52 was originally drilled to a depth of 479 feet between the dates of January 19 and 23 1995 This borehole encountered bedrock at 155 feet below ground surface and is cased to 18 feet Groundwater was observed at 122 feet below ground surface On February 13 1995 obstructions were noted in the borehole at depth of 22 and 38 feet during pre-packer testing borehole development These obstructions coincide with bedrock fracture zones observed during the drilling process and prevented GZA from packer testing the hole On February 21 1995 the drilling contractor remobilized to this location and redrilled the boring to remove these obstructions On February 28 GZA again attempted to packer test the boring and another obstruction was encountered at a depth of 22 feet We also attempted to pass a 2-inch ID well screen past the obstruction and to remove the obstruction using a 250 pound sand bailer both attempts were unsuccessful

Consequently the boring has to be redrilled prior to any testing or well installation A review of the log for this boring indicates that the most likely water bearing fractures were encountered at depths of 20 to 22 feet 31 to 32 feet and 38 feet Due to the potential for additional borehole collapse we feel it is not prudent to attempt to packer test this borehole We recommend redlining the boring using removable steel casing grouting the lower borehole to a depth of 39 feet and installing a well screened from 22 to 28 feeD The sand pack would thus extend from 20 to 39 feet and span the three most likely water bearing fractures We believe that such an installation would adequately meet all the functional requirements of the previously approved well design for future piezometric and water quality monitoring We are awaiting EPAs approval of this proposed plan prior to any further work at this location

Draft boring logs for the six originally scheduled shallow bedrock borings and three additional overburden borings are provided as Attachment A

Packer Testing Program

Packer permeability testing and discrete zone groundwater sampling commenced on February 1 1995 at location MW95-49 This program was also impacted by the extremely cold weather which caused some equipment to freeze Space heaters were necessary to warm all water bearing equipment associated with the testing Tests which were potentially affected by frozen flow meters or lineswere redone after warming the equipment By February 10 1995 GZA had completed packer permeability testing and discrete zone sampling of shallow boreholes MW95-47 748 -49 -50 and -51 As described in the FSP the borings were developed prior to in-situ testing and upon completion of packer testing the contractor purged a volume of water equal to that lost

Central Landfill Operable Unit 2 RIFS Progress Report No 2 Page 2 of 5

to the formation during testing This program had to be temporarily suspended on February 13 1995 when it was discovered that the borehole of MW95-52 had partially caved-in at 22 and 38 feet below ground surface Draft field screening results laboratory GCVOC screening results and hydraulic conductivity test results are provided on the table in Attachment B

Well Installations

The drilling contractor began installing the shallow bedrock monitoring wells on oz February 13 1995 with well screen elevations based on an evaluation of the drilling logs permeability data and laboratory GCVOC screening results These data are summarized on the table in Attachment B Wells were installed at borehole locations MW95-48 -49 shy50 and -51

Borehole Geophysical Analysis

Hager Geosciences Inc of Waltham Massachusetts performed a suite of borehole geophysical testing beginning March 3 and ending March 7 1995 Temperature and 3shyarmed caliper logging were performed on March 3rd in the deep borehole MW95-ML9 and the other three Hot Spot test borings (MW91-ML6 -ML7 and -ML8) To avoid cross contamination the logging proceeded from the holes believed to be least-contaminated to the most-contaminated boring (ie MW95-ML9 MW91-ML6 MW91-ML8 and finally MW91-ML7) and downhole equipment was carefully decontaminated between boreholes Acoustic Borehole Televiewer (ATV) logging was sub-contracted to Colog Inc of Golden Colorado Logging of all four test borings was performed in the same order described above on March 6 1995 Colog demobilized from the site on March 7 1995 Hager Geosciences is preparing a complete data report summarizing the observed features to be used in selecting well screen locations in borehole MW95-ML9

A draft boring log for this hole is provided in Attachment A

Other Boreholes

Boring MW95-52 was originally drilled to a depth of 479 feet between the dates of January 19 and 23 1995 This borehole encountered bedrock at 155 feet below ground surface and is cased to 18 feet Groundwater was observed at 122 feet below ground surface On February 13 1995 obstructions were noted in the borehole at depth of 22 and 38 feet during pre-packer testing borehole development These obstructions coincide with bedrock fracture zones observed during the drilling process and prevented GZA from packer testing the hole On February 21 1995 the drilling contractor remobilized to this location and redrilled the boring to remove these obstructions On February 28 GZA again attempted to packer test the boring and another obstruction was encountered at a depth of 22 feet We also attempted to pass a 2-inch ID well screen past the obstruction and to remove the obstruction using a 250 pound sand bailer both attempts were unsuccessful

Consequently the boring has to be redrilled prior to any testing or well installation A review of the log for this boring indicates that the most likely water bearing fractures were encountered at depths of 20 to 22 feet 31 to 32 feet and 38 feet Due to the potential for additional borehole collapse we feel it is not prudent to attempt to packer test this borehole We recommend redlining the boring using removable steel casing grouting the lower borehole to a depth of 39 feet and installing a well screened from 22 to 28 feeD The sand pack would thus extend from 20 to 39 feet and span the three most likely water bearing fractures We believe that such an installation would adequately meet all the functional requirements of the previously approved well design for future piezometric and water quality monitoring We are awaiting EPAs approval of this proposed plan prior to any further work at this location

Draft boring logs for the six originally scheduled shallow bedrock borings and three additional overburden borings are provided as Attachment A

Packer Testing Program

Packer permeability testing and discrete zone groundwater sampling commenced on February 1 1995 at location MW95-49 This program was also impacted by the extremely cold weather which caused some equipment to freeze Space heaters were necessary to warm all water bearing equipment associated with the testing Tests which were potentially affected by frozen flow meters or lineswere redone after warming the equipment By February 10 1995 GZA had completed packer permeability testing and discrete zone sampling of shallow boreholes MW95-47 748 -49 -50 and -51 As described in the FSP the borings were developed prior to in-situ testing and upon completion of packer testing the contractor purged a volume of water equal to that lost

Central Landfill Operable Unit 2 RIFS Progress Report No 2 Page 2 of 5

to the formation during testing This program had to be temporarily suspended on February 13 1995 when it was discovered that the borehole of MW95-52 had partially caved-in at 22 and 38 feet below ground surface Draft field screening results laboratory GCVOC screening results and hydraulic conductivity test results are provided on the table in Attachment B

Well Installations

The drilling contractor began installing the shallow bedrock monitoring wells on oz February 13 1995 with well screen elevations based on an evaluation of the drilling logs permeability data and laboratory GCVOC screening results These data are summarized on the table in Attachment B Wells were installed at borehole locations MW95-48 -49 shy50 and -51

Borehole Geophysical Analysis

Hager Geosciences Inc of Waltham Massachusetts performed a suite of borehole geophysical testing beginning March 3 and ending March 7 1995 Temperature and 3shyarmed caliper logging were performed on March 3rd in the deep borehole MW95-ML9 and the other three Hot Spot test borings (MW91-ML6 -ML7 and -ML8) To avoid cross contamination the logging proceeded from the holes believed to be least-contaminated to the most-contaminated boring (ie MW95-ML9 MW91-ML6 MW91-ML8 and finally MW91-ML7) and downhole equipment was carefully decontaminated between boreholes Acoustic Borehole Televiewer (ATV) logging was sub-contracted to Colog Inc of Golden Colorado Logging of all four test borings was performed in the same order described above on March 6 1995 Colog demobilized from the site on March 7 1995 Hager Geosciences is preparing a complete data report summarizing the observed features to be used in selecting well screen locations in borehole MW95-ML9

PHASE I OU2RI TASK SCHEDULE

In accordance with the requirements of the Second Amendment to the April 1987 Administrative Order by Consent GZA has prepared the following estimated schedule of Phase I OU2RI deliverables

bull Sampling and Analysis Plan (SAP) and Schedule for Task 1

bull SAP and Schedule will be submitted 45 days after receipt of EPA comments to the Upper Simmons Reservoir Phase II Report OU2 Task 1 and Ecological Characterization OU2 Task 2 Report assuming a Risk Assessment contractor has been selected and is available for consultation

Central Landfill Operable Unit 2 RIFS Progress Report No 2 Page 3 of 5

bull SAP and Schedule for Task 3

bull SAP and Schedule will be submitted on or before March 31 1995

bull SAP and Schedule for Task 4

bull SAP and Schedule have been submitted and approved work is in progress and is scheduled for completion by April 24 1995 A task specific report will be submitted within 30 days of the completion of field studies Based on EPAs comments to the Draft OU2 Work Plan it appears that more drilling will be required within the OU2 study area A SAP and schedule for the completion of this work will be provided after the scope of the project is determined in conjunction with EPA

oz

bull SAP and Schedule for Task 5

bull SAP and Schedule will be submitted within 45 days of a meeting with the RISWMC EPA and the RIFS and RA project teams to determine the project scope and data needs

bull SAP and Schedule for Task 7

bull SAP and Schedule will be submitted on or before April 28 1995

bull SAP and Schedule for Task 8 (formerly Task 9 - Data Validation)

bull SAP and Schedule will be submitted within 45 days of the finalization of all Phase I OU2RI environmental sample collection and analytical plans

UPCOMING EVENTSACTIVITIES

Meetings

RISWMC recommends that a meeting be scheduled between the RISWMC EPA and the RIFS and RA project teams as soon as a Risk Assessment contractor has been selected The purpose of this meeting will be to discuss and finalize to the extent possible scope of the Phase I OU2RI OU2FS and OU2RA Specifically the RI data collection programs need to reflect the data quality objectives developed in concert with the RA and FS goals

Central Landfill Operable Unit 2 RIFS Progress Report No 2 Page 4 of 5

Field Activities

OU2Task 4 - Well Installations Field activities for this task will continue into the next reporting period and will likely include the following

bull The drilling contractor will remobilize to the site March 8 1995 to remove accumulated debris from MW95-47 and install a monitoring well at this location Development and packer testing of borehole MW95-ML9 will commence the week of March 13 1995 GZV

bull Subsequent to the testing of boring MW95-ML9 GZA will evaluate the VOC screening geophysical analysis and hydraulic conductivity testing and submit recommendation to EPA regarding the placement of wells within this hole

bull Deep Borehole Well Installation - anticipated start date is April 10 and completion date is April 12 1995

bull As-built survey of exploration locations - anticipated completion the week of April 17 1995

Please note that field activities are highly dependant on the weather and the availability of subcontractors and equipment and are thus subject to change We will notify EPA and RIDEM as such changes become evident

to the formation during testing This program had to be temporarily suspended on February 13 1995 when it was discovered that the borehole of MW95-52 had partially caved-in at 22 and 38 feet below ground surface Draft field screening results laboratory GCVOC screening results and hydraulic conductivity test results are provided on the table in Attachment B

Well Installations

The drilling contractor began installing the shallow bedrock monitoring wells on oz February 13 1995 with well screen elevations based on an evaluation of the drilling logs permeability data and laboratory GCVOC screening results These data are summarized on the table in Attachment B Wells were installed at borehole locations MW95-48 -49 shy50 and -51

Borehole Geophysical Analysis

Hager Geosciences Inc of Waltham Massachusetts performed a suite of borehole geophysical testing beginning March 3 and ending March 7 1995 Temperature and 3shyarmed caliper logging were performed on March 3rd in the deep borehole MW95-ML9 and the other three Hot Spot test borings (MW91-ML6 -ML7 and -ML8) To avoid cross contamination the logging proceeded from the holes believed to be least-contaminated to the most-contaminated boring (ie MW95-ML9 MW91-ML6 MW91-ML8 and finally MW91-ML7) and downhole equipment was carefully decontaminated between boreholes Acoustic Borehole Televiewer (ATV) logging was sub-contracted to Colog Inc of Golden Colorado Logging of all four test borings was performed in the same order described above on March 6 1995 Colog demobilized from the site on March 7 1995 Hager Geosciences is preparing a complete data report summarizing the observed features to be used in selecting well screen locations in borehole MW95-ML9

PHASE I OU2RI TASK SCHEDULE

In accordance with the requirements of the Second Amendment to the April 1987 Administrative Order by Consent GZA has prepared the following estimated schedule of Phase I OU2RI deliverables

bull Sampling and Analysis Plan (SAP) and Schedule for Task 1

bull SAP and Schedule will be submitted 45 days after receipt of EPA comments to the Upper Simmons Reservoir Phase II Report OU2 Task 1 and Ecological Characterization OU2 Task 2 Report assuming a Risk Assessment contractor has been selected and is available for consultation

Central Landfill Operable Unit 2 RIFS Progress Report No 2 Page 3 of 5

bull SAP and Schedule for Task 3

bull SAP and Schedule will be submitted on or before March 31 1995

bull SAP and Schedule for Task 4

bull SAP and Schedule have been submitted and approved work is in progress and is scheduled for completion by April 24 1995 A task specific report will be submitted within 30 days of the completion of field studies Based on EPAs comments to the Draft OU2 Work Plan it appears that more drilling will be required within the OU2 study area A SAP and schedule for the completion of this work will be provided after the scope of the project is determined in conjunction with EPA

oz

bull SAP and Schedule for Task 5

bull SAP and Schedule will be submitted within 45 days of a meeting with the RISWMC EPA and the RIFS and RA project teams to determine the project scope and data needs

bull SAP and Schedule for Task 7

bull SAP and Schedule will be submitted on or before April 28 1995

bull SAP and Schedule for Task 8 (formerly Task 9 - Data Validation)

bull SAP and Schedule will be submitted within 45 days of the finalization of all Phase I OU2RI environmental sample collection and analytical plans

UPCOMING EVENTSACTIVITIES

Meetings

RISWMC recommends that a meeting be scheduled between the RISWMC EPA and the RIFS and RA project teams as soon as a Risk Assessment contractor has been selected The purpose of this meeting will be to discuss and finalize to the extent possible scope of the Phase I OU2RI OU2FS and OU2RA Specifically the RI data collection programs need to reflect the data quality objectives developed in concert with the RA and FS goals

Central Landfill Operable Unit 2 RIFS Progress Report No 2 Page 4 of 5

Field Activities

OU2Task 4 - Well Installations Field activities for this task will continue into the next reporting period and will likely include the following

bull The drilling contractor will remobilize to the site March 8 1995 to remove accumulated debris from MW95-47 and install a monitoring well at this location Development and packer testing of borehole MW95-ML9 will commence the week of March 13 1995 GZV

bull Subsequent to the testing of boring MW95-ML9 GZA will evaluate the VOC screening geophysical analysis and hydraulic conductivity testing and submit recommendation to EPA regarding the placement of wells within this hole

bull Deep Borehole Well Installation - anticipated start date is April 10 and completion date is April 12 1995

bull As-built survey of exploration locations - anticipated completion the week of April 17 1995

Please note that field activities are highly dependant on the weather and the availability of subcontractors and equipment and are thus subject to change We will notify EPA and RIDEM as such changes become evident

UPCOMING EVENTSACTIVITIES

Meetings

RISWMC recommends that a meeting be scheduled between the RISWMC EPA and the RIFS and RA project teams as soon as a Risk Assessment contractor has been selected The purpose of this meeting will be to discuss and finalize to the extent possible scope of the Phase I OU2RI OU2FS and OU2RA Specifically the RI data collection programs need to reflect the data quality objectives developed in concert with the RA and FS goals

Central Landfill Operable Unit 2 RIFS Progress Report No 2 Page 4 of 5

Field Activities

OU2Task 4 - Well Installations Field activities for this task will continue into the next reporting period and will likely include the following

bull The drilling contractor will remobilize to the site March 8 1995 to remove accumulated debris from MW95-47 and install a monitoring well at this location Development and packer testing of borehole MW95-ML9 will commence the week of March 13 1995 GZV

bull Subsequent to the testing of boring MW95-ML9 GZA will evaluate the VOC screening geophysical analysis and hydraulic conductivity testing and submit recommendation to EPA regarding the placement of wells within this hole

bull Deep Borehole Well Installation - anticipated start date is April 10 and completion date is April 12 1995

bull As-built survey of exploration locations - anticipated completion the week of April 17 1995

Please note that field activities are highly dependant on the weather and the availability of subcontractors and equipment and are thus subject to change We will notify EPA and RIDEM as such changes become evident

Field Activities

OU2Task 4 - Well Installations Field activities for this task will continue into the next reporting period and will likely include the following

bull The drilling contractor will remobilize to the site March 8 1995 to remove accumulated debris from MW95-47 and install a monitoring well at this location Development and packer testing of borehole MW95-ML9 will commence the week of March 13 1995 GZV

bull Subsequent to the testing of boring MW95-ML9 GZA will evaluate the VOC screening geophysical analysis and hydraulic conductivity testing and submit recommendation to EPA regarding the placement of wells within this hole

bull Deep Borehole Well Installation - anticipated start date is April 10 and completion date is April 12 1995

bull As-built survey of exploration locations - anticipated completion the week of April 17 1995

Please note that field activities are highly dependant on the weather and the availability of subcontractors and equipment and are thus subject to change We will notify EPA and RIDEM as such changes become evident
