Patent granted for: Rapid Perchlorate Destruction in Soil and Groundwater Through Bioaugmentation

IRWIN, together with its co-inventor, has proven that perchlorate contamination can be successfully treated using a new patented process. By adding a registered strain of facultative bacteria, nutrients and appropriate buffering IRWIN showed that even high levels of perchlorate can be rapidly reduced in situ in soil and groundwater.Perchlorate, a propellant used in flares, rockets and fireworks, is a contaminant at more than 400 sites across the United States. To date, in-situ biological treatment of perchlorate has been attempted with anaerobic species using various carbon substrates with limited success.Irwin Engineers Perchlorate Treatment Case Study


2016 was another successful Toxic Use Reduction Filing  year

Andy Irwin, PE, LSP, TURP, CPEA is certified for TUR Plans and Resource Conservation Plans. He is a BEAC Certified Professional Environmental Auditor ISO14000 Plus. He is a former President, Treasurer and Board Member of the Toxics Use Reduction Planners Association

The TURA program is intended to facilitate and encourage pollution prevention opportunities by evaluating operations and identifying feasible options for reducing the use of toxics. Facility personnel, along with a certified TUR Planner, work to identify TUR options and evaluate them for their technical and economic feasibility.  In many cases, we have found that implementing various TUR opportunities not only reduced the amount of toxics used, but also reduced costs and improved efficiency for our clients.Read more

Project Examples:

  • We worked with one facility that eliminated their use of VOCs, allowing them to turn their emission control catalytic oxidizer off and save over $120,000 a year.
  • We identified an option for a processing facility to recover a rare earth metal from a toxic waste stream, eliminating disposal costs of $150,000 a year, and instead generating additional revenue from the recovered material.
  • As an alternative to a TUR filing this year, we completed a Resource Conservation (RC) Plan for a facility wishing to reduce energy costs. The audit resulted in recommendations that yield annual energy savings of 13.6% with a financial payback time of just over one year.
  • We reduced the amount of planning required for a facility by incorporating TUR into their Environmental Management System. This integration helps reduce the time required to fulfill regulatory obligations and raises awareness of TUR chemical use as significant environmental aspects of the operation.

We serve a wide range of industries including:

  • Chemical Manufacturers and Blenders
  • Food and Beverage Preparation
  • Commercial and Industrial Launderers
  • Printers and Ink Manufacturers
  • Semiconductor Manufacturers
  • Glass Processors
  • Fiberglass Manufacturers
  • Pharmaceutical Manufacturers
  • Polymer Membrane Manufacturers
  • Electric Utilities
  • Electrical Equipment Manufacturers
  • Paper and Cardboard Manufacturers
  • Foundries
  • Metal Platers
