20130032534 | DENITRIFICATION PROCESS FOR REMEDIATION OF CONTAMINATED GROUNDWATER AND SOIL - Processes for removing hydrocarbon contaminants from soil and groundwater via enhanced biological denitrification. A contamination zone of groundwater and/or soil is identified to define a volume or zone of contaminants to be treated. A source of nitrate is applied to the contaminant zone to serve as an electronic acceptor for enhanced bioremediation of the petroleum hydrocarbons. A further carbon source, secondary to the primary contaminant hydrocarbons, is added to form a barrier about the nitrate treatment zone to stimulate degradation of any nitrate migrating from the treatment zone. A further carbon source is also added to stimulate the degradation of any residual nitrate once the primary carbon source of the contaminant hydrocarbons have been destroyed. | 02-07-2013 |
20130152503 | METHOD OF PREVENTING INTRUSION OF TOXIC VAPOR INTO INDOOR AIR - Methods of preventing intrusion of toxic vapor into a building's interior air space. Contaminants operative to diffuse through a building's foundation and contaminate a building's interior air space are first determined. Once identified, the building's foundation, typically formed of concrete, will first be prepared for surface treatment followed by an application of at least one coating of a material suitable for imparting chemical resistance in the concrete. Such material may include novolac, vinyl novolac and related resin-based epoxy coatings. Such coatings, once applied, provide a protective barrier from commonly encountered contaminants, including a wide variety of volatile organic compounds. Such coatings are further expected to last the life of the building, or until physical wear requires repair or replacement. | 06-20-2013 |

20150034559 | COLLOIDAL AGENTS FOR AQUIFER REMEDIATION - Compositions and methods for treating contaminated soil and/or ground water in situ. The compositions and methods comprise stabilized forms of colloidal activated carbon that are used to quickly sorb contaminants. Unlike traditional activated carbon in granular or powder form, the compounds and methods of the present invention are operative to transport particulate activated carbon through a matrix of soil and groundwater upon application by injection, gravity feed, or percolation into soil and groundwater, which in turn decontaminate groundwater in place without the cost or disruption associated with digging the contaminated soil and groundwater out of the ground for on-site purification or disposal at a hazardous waste landfill. | 02-05-2015 |
