North Carolina, USA
He was hired by a legal firm to provide expert assessment of flooding that resulted due to the widening of a highway. He visited the site, engaged a subcontractor to carry out drilling at the site to collect soils samples and subcontracted a soil testing lab to measure the hydraulic properties of the soils to evaluate why the site repeatedly flooded. He carried out computer modeling to simulate the weather at the site and assess the flooding. He prepared an expert technical report to his client (the legal firm). The legal firm was able to use the report and settle the lawsuit.
He was hired by a legal firm to provide expert technical advice for clean up of soil contamination that had resulted due to the historic operations of dry cleaning. He visited the site and based on the soil types and depth of groundwater, he recommended the appropriate cost-effective technology and the name of qualified contractors to carry out the cleanup.
He was hired by a waste operator to provide expert advice on how to improve the gas yield from his landfills. The gas is used to run gas to energy plant. He visited the landfill site and evaluated the properties of the waste including water content, density, age, and type of placement and recommended a different design to extract the gas more efficiently.
He was hired by a civil engineering consulting company to design a gold mine leach pond. The gold mine created a waste product which had to be drained in a pond and the leachate had to be treated. He carried out computer modeling of the drainage from the mine waste using a sophisticated state-of-the-art numerical model that simulates the hydraulic flow. The technical report he prepared helped the client secure a permit from the local regulatory agency. He was hired by a waste operator to install hydrologic monitoring systems at a number of landfill sites. He installed weather stations and subsurface sensors that measure soil water contents, soil water potentials, soil temperatures, and water pressures. He installed dataloggers to log the data and access the data remotely using telemetry.

Additional Experience
| Expert Witness Experience |
|---|
| Expert witness for a flooding related lawsuit due to highway widening in a mid-western state in the US. My expert witness work involved writing an expert report for the plaintiff to demonstrate the widening of the highway and poor stormwater management for runoff from the highway resulted in flooding many adjacent properties. I used hydrologic data, assisted in engaging a drliing company and soil testing lab to test hydraulic properties of the soils and run a hydrologic computer model to demonstrate why the plaintiff's properties were flooded. The expert report I prepared helped in a settlement that was favorable for the plaintiff. Expert witness for flooding of a private property related lawsuit where an adjacent subdivision construction resulted in flooding of plaintiff's property. I helped the attorney representing plaintiff to evaluate the reasons why the flooding was occurring before the lawsuit was filed by the plaintiff. Expert witness for a lawsuit where the defendant was sued due to problems from separation of recycled materials in a material recovery facility (MRF). I assisted the attorneys representing the defendant and prepared an expert report on technical data that supported how MRFs are designed and operated. I was hired to prepare designs of water balance covers for landfills in Texas. Texas Commission on Environmental Quality (TCEQ) was the key reviewer of the design report I prepared and many landfill owners/operators were the key stake holders. The project involved mapping hydrology of the entire state of Texas (from El Paso to Houston) and testing soils across many sites in Texas and running state-of-the-art computer model UNSAT-H to simulate the field hydrology of landfill covers. The design report that I prepared has been adapted by TCEQ into its design guidance for landfill covers and is widely used across the state of Texas. |
