Remediation• Voluntary cleanup with Los Angeles RWQCB

• Soil closure in 2008

• Groundwater extraction & treatment system started in February 2012

• Hydraulic containment of VOCs at downgradient property boundary at 65 gpm– 60 gpm: A-Sand extraction well (EW)– 2.5 gpm: two BFA EWs

• Activated carbon filtration & injection to A-Sand via 5 upgradient injection wells (IWs)

The problemDiminished injection performance within 2 years of startup and significant downtime to manage injection well fouling

• 3 original IWs offline (1 broken, 2 fouled with precipitate)

• 2 newer IWs showing similar signs of precipitate fouling

• 1 IW receiving 80% of discharge – no contingency; high risk of failure

• VOC concentrations varied in downgradient A-Sand monitoring wells due to system downtime

5

The problem (continued)• Limited understanding of hydraulic property variations in A-Sand made it

difficult to evaluate well capture zones

• EW bio-fouling complicated evaluation.

• Discharge to storm drain evaluated, not considered option due to other effluent limitations (chloride, sulfate).

• $1M connection fee to divert discharge to sanitary sewer made taking a holistic approach to optimizing of entire system worthwhile, from extraction to injection, to continue original and more sustainable (recharge) remedy.

6

Evaluate variations in A-Sand characteristics and VOCs to support understanding & optimization of capture zones• Environmental Sequence Stratigraphy (ESS): understand depositional characteristics and correlate laterally• Extraction well EW0101 evaluation:

– Video survey

– Vertical flow log & depth-integrated groundwater samples at 30 & 60 gpm

– Well rehabilitation & redevelopment

• Review historical pumping test data to estimate range of A-sand transmissivity & hydraulic conductivity (Kh)• Groundwater modeling to obtain best fit for K values in UAS & LAS based on flow survey data &

groundwater elevation contours during pumping from UAS & LAS.

• UAS pumping tests at 40 & 60 gpm in EW0101, to confirm best fit K value for UAS. (10 days each with hourly data recording using pressure transducers).

Approach to optimize extraction

• BFA = Holocene Dominquez unit • Channel-fill and flood plain deposits • Formed due to climatic changes at end of

last glacial period• Complex sand/silt deposits with low

permeability

• A-Sand = Pleistocene Mesa unit• Shallow water marine to marginal marine as

well as non-marine fluvial and alluvial fan deposits

• Formed due to shoreline progradation• Homogeneous sand units with variable

transmissivity:• Upper A-Sand – on-Site • Middle A-Sand – primary pathway for off-

Site plume• Lower A-Sand – shallow marine with shell

marker beds

EW0101 video log, flow survey, & redevelopment -February 2017• UAS is aerobic – significantly affected by

bio-chemical fouling; redevelopment increased discharge by 13%

• LAS is anaerobic – bio-chemical fouling not observed, redevelopment did not change discharge

• Following rehabilitation, UAS accounts for 89% & LAS 11% of total well discharge.

• Specific capacity increased from 1 gpm/ft to 2 gpm/ft and water level sustained above top of UAS screen

Historical pumping test data & modeling• Modeling used to estimate best-fit for hydraulic

conductivity (Kh)

• Estimated historical Kh values for UAS range from 6.6 to 160 ft/day. Data not available for LAS.

• Best fit to observed groundwater elevation contours indicated Kh ~140 ft/day for UAS & 17.5 ft/day for LAS

LAS: K=20 ft/d EW0101 - 60 gpmIW0104 - 50 gpm IW0105 - 15 gpm

UAS: K=160 ft/d EW0101 - 60 gpmIW0104 - 50 gpm IW0105 - 15 gpm

Extraction optimization summary• Findings

– Sequence stratigraphy, flow logging, depth-integrated sampling & modeling revealed vertical variation in K & VOC concentrations

• Optimization opportunity – Most VOC mass in UAS; pumping from LAS induces

drawdown & downward vertical gradient; pumping from LAS has little benefit

14

Extraction optimization summary (continued)• Extraction optimization

– Packer installed in EW0101 to isolate UAS from LAS– Pumping tests in UAS at 40 & 60 gpm for 10 days each

• 40 gpm: best fit mean Kh of 130 ft/day• 60 gpm: best fit mean Kh of 126 ft/day

– 40 gpm from UAS provides similar CZ as 60 gpm for combined UAS/LAS, saving 20 gpm extraction & treatment

15

Extraction optimization verification• As expected, 60 gpm capture zone (CZ) larger than 40 gpm CZ in UAS, however….

• UAS 40 gpm CZ similar in size to 60 gpm UAS/LAS combined CZ at 60 gpm (not shown)

Approach to optimize injectionIs injection a viable discharge method? Our approach included the following…

• Review previous investigations of injection well fouling• Collect samples of precipitate from injection wells• Research and test additional well rehabilitation methods• Collect water samples at influent, midpoint, & effluent of treatment system• Install effluent particulate filter• Test effect of aeration to encourage precipitation within treatment system surge tank• Evaluate additional oxide mitigation measures• Conduct cost-benefit analysis of long-term well rehabilitation & replacement versus

one-time cost of sewer connection ($1M)

• Sediment samples collected from IW0104 contained 29% (dry weight) manganese. Additional sampling confirmed presence of manganese & iron oxides

• Based on these results, effluent particulate filter unit installed on treatment system & further evaluation of manganese performed to identify locations of potential manganese precipitation in treatment system

• Acid treatment with NuWell 120 & 310 for 36 hours – acid removed prior to next step• Backflush >4,500 gallons at 70+ gpm – removes particles from within screen openings• Sonar jetting – high-pressure pulse to break up oxide scale• Water jetting• Mechanical development – removes heavy particles & brushes screen• Video survey before/after for confirmation of condition
