Remediation of a Former Marine Terminal, Southern California
After a marine terminal was demolished, several site assessments revealed that soil and groundwater at the site were affected with petroleum hydrocarbons and lead. An interim remedial action plan (IRAP), a remedial action plan (RAP), and a sampling and analysis plan (SAP) were prepared and implemented to protect harbor water, and remediate the site.

Groundwater Remediation using Air Sparge | Pilot Testing, Design, Construction, and Operation
Air sparge is an in situ groundwater remediation technology which uses vertical or horizontal wells to transfer a continuous or pulsed flow air into the groundwater. The purpose of air sparge system is to reduce the concentrations of volatile organic compounds (VOCs) in groundwater through enhanced volatilization, and mass transfer of VOCs and oxygen.

Advanced Oxidation using Ultraviolet Light and Hydrogen Peroxide
Advanced oxidation systems using hydrogen peroxide (peroxide) and ultraviolet (UV) light are designed to inject hydrogen peroxide in controlled ratios to the water, then mixing the peroxide, and exposing the water and peroxide solution to UV radiation to form hydroxyl radicals (•OH). Peroxide and hydroxyl radicals are strong oxidizing agents capable of oxidizing 1,4-dioxane and several volatile organic compounds (VOCs). The advanced oxidation process is suitable for groundwater remediation with pump-and-treat, water treatment, and industrial wastewater treatment. Treatment with UV/Peroxide may offer technical advantages over ozone based treatment systems.
