Specific Experiences as Principal Coordinator
o Developed the conceptual model for FOOTPRINT, which estimates the area of
any BTEX plumes in presence of ethanol. In the United States, ethanol is
used as an additive to gasoline as well as an alternative energy source
for automobiles. Although ethanol is biodegradable, it has a potential
risk of enlarging the BTEX plumes by prohibiting natural attenuation of
BTEX compounds in case of a gasoline spill. FOOTPRINT is designed to
predict expansion of the BTEX plumes caused by the presence of ethanol.
It was used to study the impact of gasoline spills for replacing MTBE in
gasoline by ethanol. Currently, FOOTPRINT is distributed through the
U.S. EPA's web site
(http://www.epa.gov/nrmrl/gwerd/csmos/models/footprint.html).
o Evaluated impact of ethanol in shallow groundwater supply from oil spills
and leaking of underground storage tanks (UST) in Sussex County, DE and
South Lake Tahoe, CA. FOOTPRINT was calibrated for impacted UST sites and
projected for enhancement of the existing plumes in presence of ethanol.
The studies were presented in two workshops (One in Philadelphia, PA and
the other in Sacramento, CA) organized by USEPA's Office of Research and
Development.
o Designed and developed NPATH, which is a Windows-based expert system, for
evaluation of groundwater pollution potential from land application of
animal manure. The Oklahoma Conservation Commission (OCC) and U.S. EPA
jointly funded NPATH. Since animal manure contains high amount of
nutrients, it is commonly used to fertilize the surrounding farm land.
However, excessive application of the manure could cause the nutrients to
contaminate the groundwater in and around the farm and subsequently pose
high health risk. The model uses fate and transport models for both
vadose and saturated zones to predict the health risk at a receptor well.
NPATH was set up as an expert system so that it does not require highly
technical personnel to conduct the simulation.
o Performed technical review of a number of groundwater fate and transport
modeling software packages. Most notable of these models are: 1) BIOCHLOR
(Natural Attenuation Decision Support System, version 2.2): simulates
natural attenuation of chlorinated solvents subjected to sequential 1st
order decay; 2) FREPRES: evaluates practicability of free product
recovery from groundwater; 3) OWL (Optimal Well Locator): evaluates
existing monitoring well network to assist in finding locations for new
monitoring wells; 4) SOURCEDK: estimates remediation time frames for a
NAPL source and assess uncertainty associated with the estimates; 5)
BIOPLUME-4: simulates natural attenuation of organic contaminants in
groundwater through the processes of advection, dispersion, sorption, and
biodegradation; 6) SMARTe (Sustainable Management Approaches and
Revitalization Tools - electronic): is a web-based decision support
system for developing and evaluating future reuse scenarios for
potentially contaminated land; and 7) REMChlor (Remediation Evaluation
Model for Chlorinated Solvents): is an analytical model for simulating
the transient effects of groundwater source and plume remediation for
chlorinated solvents. 8) BioVapor: 1-D model for vapor intrusion into
buildings from petroleum byproducts in the vadose zone.
o Performed technical review of more than 50 groundwater models calibrated
for RCRA and Superfund sites regulated by the U.S.EPA. Groundwater flow,
solute transport, water budget and particle tracking models were applied
in various sites to evaluate remediation and hydraulic containment
systems, such as, pump-and-treat, PRB, SVE, and MNA.
o Performed aquifer tests (e.g., slug test), field sampling and testing of
soil, groundwater and lagoon waste, and laboratory analyses of soil
(e.g., classification, permeability from tri-axial test, and porosity)
and groundwater (e.g., BOD5, COD, DO, microbial plate count, atomic
absorption spectroscopy) in two animal feedlots for 3 years. Supervised
monitoring well installation and prepared borehole logs for the sites.
Conducted site assessment based on the field and laboratory test data.
o Applied groundwater flow and transport models (e.g., MODFLOW, MODPATH,
MT3DMS, RT3D, BIOCHLOR, and PEST) to predict the life of chlorinated
solvents and ethanol plumes at the former Sage's dry cleaning facility in
Jacksonville, Florida. This site is one of the premier sites where the
SERB (Solvent Extraction and Residual Biotreatment) technology was
applied for removal and remediation of chlorinated solvents (e.g., PCE,
TCE, DCE and VC) through ethanol flushing. An EQuIS database was
developed to manage the extensive field data (e.g., water levels,
hydrographs, tracer test, chemical analyses, and aquifer tests) collected
during the 4-year long study.
o Conducted subsurface modeling to estimate moisture flow through the root
zone in a variety of grass field at the Gaar Corner Site in Ada,
Oklahoma. The purpose of the study was to find the indicators of nitrate
leaching for different land use and soil type. HYDRUS, a state-of-
practice finite element model for flow and transport through the vadose
zone, was used. The model was calibrated and validated with respect to
field measured suction potential data at 4 different depths in the root
zone. Unsaturated hydraulic conductivity of the root zone soil was
measured using the Guelph Permeameter. Inverse modeling approach was
followed to calibrate the model. The findings of the modeling study were
published in a peer-reviewed journal.
o Calibrated a MODFLOW-based groundwater flow model for the former Cimarron
Pork facility. The site is contaminated with ammonia and nitrate nitrogen
originating from the unlined lagoon. Two Permeable Reactive Barriers
(PRB) are currently in place to treat the ammonia and nitrate plumes. A
steady-state flow model was calibrated using the PEST code. Water budget
and particle tracking analyses were also conducted using the 'Zone
Budget' and MODPATH codes, respectively.
o Conducted preliminary design of a PRB for remediation of arsenic in the
Asarco Superfund Site at East Helena, Montana. U.S. EPA was involved in a
pilot-scale study to design and install a PRB at the site. Since the
aquifer is highly heterogeneous, it was a challenge to the researchers to
find an optimum size and permeability of the PRB that can effectively
attract the flow towards the PRB. Groundwater flow and particle tracking
models were applied to study the sensitivity of the capture zone to a
range of hydraulic conductivity values for the PRB. Based on the
sensitivity analyses, optimum size and permeability of the PRB were
determined. U.S.EPA has recently installed the PRB in the site.
o Calibrated a groundwater flow model for the Plaquemine aquifer in
Louisiana. The objective of the modeling study was to identify the
possible source(s) of the vinyl chloride plume in the aquifer. A
transient flow model was calibrated to match the groundwater level
fluctuation caused by the Mississippi River. Particle tracking analysis
was conducted to identify the possible source locations.
o Evaluated the Soil Vapor Extraction (SVE) system operating at the Kellogg-
Deering site in Norwalk, Connecticut. A methodology was developed to
measure site-specific soil-water partitioning coefficient for VOC from a
methanol preserved soil sample. The study was also an initial effort in
collecting field data for modeling fate and transport of VOC through the
vadose zone.
