Remedial Injections
By Yash Saha, Chemical Engineer

New technologies have made the injection of chemical or biological solutions a faster, more convenient and inexpensive way to treat groundwater contaminated with petroleum or chemical solvents. These solutions are injected into the ground utilizing Hydro Tech’s Fleet of Geoprobes®. The injection typically takes place over a 1 week period and can be performed in areas varying from construction sites to beneath building slabs. Once injected the progress of groundwater/soil remediation is monitored until levels of contaminants are remediated. Remediation typically occurs over a one to two year period of time. Using this method of remediation Hydro Tech has successfully closed several New York State Department of Environmental Conservation (NYSDEC) Spill Sites.

There are many different types of chemical/biological treatments available. Hydro Tech can determine the appropriate remedial treatment by analyzing the site specific geology and the chemical nature of your spill. Typically, chemical treatments consist of oxidation of the contaminants via application of remedial additives such as hydrogen peroxide, Fenton's Reagent, sodium or potassium permanganate. Typically biological treatments consists of stimulating microorganisms that are either naturally occurring at or near the treatment location or introducing cultured microorganisms into the treatment area.

Chemical and biological treatment of soil and groundwater contamination is becoming the most common remedial method. Contact Hydro Tech today to discuss how we can remediate your groundwater or soil contaminants.
