Nicholas Sitar

Title: Nicholas Sitar - Innovator in Environmental Remediation

Introduction

Nicholas Sitar is a notable inventor based in Kensington, CA (US). He has made significant contributions to the field of environmental remediation, particularly in the area of subsurface decontamination. His innovative methods aim to address the challenges posed by contaminated soil and groundwater.

Latest Patents

Nicholas Sitar holds a patent for a process titled "Process for in situ decontamination of subsurface soil and groundwater." This method involves the injection of steam into contaminated subsurface areas through injection wells. It also includes the withdrawal of liquids and vapors from extraction wells under subatmospheric pressure. The steam is passed through the contaminated area in an essentially horizontal direction, effectively removing a substantial portion of the contamination. After this initial phase, steam injection is ceased, but extraction continues to volatilize and remove residual contaminants trapped in the soil. The process may involve periodic resumption of steam injection to reheat the area and replenish water in the soil pores.
