ARCADIS

The hydrogeologic evaluation was conducted to evaluate the hydraulic interaction of the Manokin Aquifer,

Bethany formation and Columbia Aquifer near the Millsboro Public Well field. The investigation activities

were completed to accomplish the following objectives:

Collect data to support analytical model construction

Monitor transient water levels under controlled pumping conditions

Define hydraulic parameters from pumping test results to expand and update existing model

Utilize the updated model to perform predictive analyses and develop recommendations

During the first two quarters of 2010 ARCADIS implemented a hydrogeologic study to assess the potential for dissolved solutes present in the Columbia Aquifer to reach the Manokin Aquifer. This investigation began with a review of the available site data as compiled by DNREC Site Investigation and Restoration Branch (SIRB). Tlje existing data provided detailed informafion about the Columbia Aquifer, the Town of Millsboro Well Field, and the existence of dissolved concentrations of trichloroethylene (TCE) and nitrate (a regional situation) in.shallow groundwater. A.reviewof the existing Site model indicated that an . expansion of the model was needed in order to properly evaluate the potential for downward migration.

To collect the data needed to expand the model a field program was implemented including monitoring well installation, groundwater sampling, and aquifer pump testing. Production Well PW-05, recently installed by the Town of Millsboro,'was selected as the extraction well for the aquifer pump test due to its location in W.B. Atkins Park, approximately 0.25 miles from the TCE plume. The field activities implemented during the hydrogeologic study are discussed in the following sections:

Monitoring Well Network

Fourteen observation wells were installed to supplement the three exisfing observation wells in the park

for the purpose of monitoring water levels in the vicinity of Millsboro Production Well PW-05. Five of the

new monitoring wells were completed in the Columbia Aquifer along two axes at distances between 120

feet (ft) and 900 ft from PW-05. Four wells were installed in a relafively high permeability zone of the

Bethany Formation, which at the Site is characterized as a leaky aquitard, although it becomes a viable

source of public water supply to the east of the Site. The remaining five wells were installed in the

Manokin Aquifer, the unit from which the Town of Millsboro intends to obtain nearly all of its drinking water.

Monitoring well locations are shown on Figure 1.

Monitoring wells completed in the Manokin aquifer were installed using rotosonic drillirig methodologies to

facilitate the collection of continuous soil cores. Monitoring well construction for wells completed in the

Bethany and Columbia formations were determined through interpretation of the soil cores collected

ARCADIS

during rotosonic drilling activities. Monitoring wells completed in the Columbia and Bethany formations were installed using mud rotary drilling techniques.- Each well installed (whether in the Columbia Aquifer, Bethany Formation, or Manokin Aquifer) was wholly screened in their respective targeted aquifer or formation. Wells were not screened across different aquifers or formations. Grout was injected into the annular space of the borehole using a tremie pipe to ensure a proper seal is installed to hydraulically isolate each well from the overlying and/or underlying aquifer/formation. Well constnjction logs are provided as Appendix A.

Following the completion of the wells, they were developed to ensure a good connection with the aquifer and therefore demonstrate an adequate response under aquifer pumping from the various production wells. Approximately two weeks after development, each of the wells were purged and sampled to verify the absence of VOC contaminafion in this area. Monitoring wells MW-16S and MW-16D were also sampled during the aquifer pump test to monitor groundwater quality during implementation of the pump test. During each sampling event groundwater samples were collected from the monitoring wells using low-flow sampling methods. Samples were preserved in the field and submitted to Shealy Environmental Services, Inc., located in West Columbia, South Carolina for analysis of VOCs by USEPA method 8260C. All wells were shown to be free from TCE. The analytical laboratory reports are provided electronically as At tachment ! . , .

Aquifer Testing

Upon successful demonstration of the lack of contamination in the newly installed monitoring wells, data logging pressure transducers (dataloggers) were installed to collect background water levels in the period leading up to the aquifer test. Approximately two weeks of data was collected before initiating the aquifer test at PW-05. The Town.of Millsboro initiated pumping of PW-05 on June 28, 2010 and continued operation over the course of the aquifer pump test through July 6, 2010. PW-05 was pumped at a rate of 500 gallons per minute (gpm) for the first four days and at 580 gpm for the next three days with well PW-01 running to supplement the water needs of the town. Water generated during the aquifer test was routed to the town's water treatment plant.

The pumping test data were used to evaluate the degree of vertical connection between the Columbia

Aquifer, Bethany Formation and Manokin Aquifer as well as to calculate hydraulic characterisfics of the

Manokin Aquifer. During the pumping test, measurable drawdown was observed in the Manokin aquifer

and the Bethany formation wells indicating a significant degree of leakage through the Bethany formation.

Modeling

The numerical model previously developed for the Site was updated and expanded to support simulation of the aquifer test and evaluation of predictive pumping scenarios as well as the evaluations of capture profiles under those pumping scenarios.

ARCADIS

The model boundaries were moved outward to nearby natural hydraulic boundaries resulting in an active

model slightly more than four square miles with a thickness of approximately 300feet.. Calibration testing

of the model produced a good match of both steady state and transient data indicating that the model

provided a good representation of the system behavior.

Once the model performance was established, several predictive scenarios were run to evaluate the

potential for vertical migration from the contaminated Columbia Aquifer down to the Manokin Aquifer.

These included: the existing operation of the Town of Millsboro well field; operation of the Columbia

aquifer wells with well PW-05; operation of the Columbia aquifer wells with wells PW-03 and PW.-05;

operation of all Manokin Aquifer wells at the capacity of the Town's water treatment system; and operation

of all Columbia and Manokin wells.

r The results ofthe numerical modeling indicated the following:

• Pumping of the Manokin Aquifer produces a rapid discernable response in the Bethany formation;

Pumping of wells PW-01 and PW-02 produce an enhanced upward flow of water from the Manokin Aquifer through the Bethany Formation to the Columbia Aquifer;

Increased pumping in the Manokin Aquifer progressively negates the beneficial upward gradient;

that naturally occurs and that is enhanced by pumping in PW-01 and PW-02; and

• ' Operation of PW-01 and PW-02 is required to control lateral and vertical plume migration.

Additional Simulations

At the meeting on August 3"* the Town of Millsboro and EPA requested that ARCADIS conduct additional

simulations to evaluate specific details of the projected operation the Millsboro Well field.

Specifically, Mr. Niblett from the Town of Millsboro requested that ARCADIS run the following scenarios: 600 gpm at PW-05; 200 gpm at PW-03 or PW-04; and pumping PW-01 and-PW-02 at a minimum level to maintain plume control, Mr. Niblett informed the participants at the August 3 * meeting that if Millsboro would be able to run the wells at these specified levels, Millsboro would have a sufficient amount of water for the near future.

In summary, ARCADIS was asked to conduct additional simulations for the following scenarios:

. 1. Interference Evaluation: evaluation of the operation of well PW-04 as a periodic replacement for well PW-03 thereby spreading the equipment use between wells PW-03 and PW-04.

Page 5: EXECUTIVE SUMMARY OF HYDROGEOLOGIC INVESTIGATION OF ...

ARCADIS

2. Minimum for Capture: evaluation of the minimum pumping rate of wells PW-01 and PW-02 required to maintain control of the plume; and

3. Reinjection: reinjection of the.water recovered by wells PW-01 and PW-02.

The above scenarios were simulated using the updated numerical model and the maximum extraction

rates for the Manokjn supply wells including a maximum extraction rate of 600 gpm at PW-05 and a

m'aximum extraction rate of 200 gpm at PW-03. A summary of the additional simulations including

assumed extraction rates, aquifer interaction analysis between the Bethany and Columbia formafions, and

simulated capture analysis for each of the three scenarios is provided as Appendix B.

The results of the additional simulafions indicated the following:

• Given the close proximity of PW-03 and PW-04 (within 125 feet of each other), wells PW-03 and PW-04 can be used interchangeably (one at a time) at a maximum rate of 200 gpm without altering the Columbia Aquifer groundwater flow direction;

• The minimum combined extraction rate from wells, F'W-01 and PW-02 required td maintain adequate control of the plume is betv/een 220 and 280 gpm, based on the mapped distribution of the plume; and '

• The predicted minimurh extraction rate between 220 and 280 gpm could be reinjected as near as the northwest corner of Atkins park without adversely impacting the upward flow fi-om the Manokin formation in the plume vicinity. . -

Recommendations

A reduction in pumping of the Columbia Aquifer (i.e., PW-01 and PW-02) risks a loss of the lateral and vertical migration control established under the present pumping scenario. The results ofthe hydrogeologic study and the numerical flow simulations indicate that pumping of the Manokin aquifer can be achieved with a reasonable degree of safety if pumping is carefully managed. Therefore, pumping of the Manokin Aquifer should be carefully managed with the maximum pumping rate at PW-05 limited to 600 gpm, and short term interrriittent pumping of wells PW-03 and PW-04 at a combined rate limited to 200 gpm. Importantly, wells PW-03 and PW-04 cannot be running at the same time. Wells PW-01 and PW-02 should operate at the current combined minimum rate of 280 gpm to balance the pumping from the Manokin Aquifer described above. Under this scenario the Town of Millsboro will not only be able to maintain plume control, but also will be able to provide a sufficient amount of water to accommodate public demand. This minimum rate should be re-evaluated as new data is obtained.
