Ivey‐sol  is an international award winning Remediation Technology Company, founded in 1993.Celebrating 25 Years In Business in 2018

We established reputation for developing innovative remediation products and processes technology. (1 + 1 = 3) 

Our most notable innovation is the Ivey‐sol® Surfactant Technology ‐ used globally.

Ivey‐sol® products and processes are very effective for in‐situ and ex‐situ remediation of petroleum hydrocarbons (LNAPL), chlorinated solvents (DNAPL), and organo‐metallic COC’s

Ivey‐sol® pairs very well with Physical, Biological and Chemical remediation technologies (1+1=3).   

Our corporate goal is to be a global leader of sustainable remediation technology for our client’s(Collaborate with other technology providers, and stakeholders to achieve Site Goals)

It’s is a relatively young industry…

Gaining Local, National, and International Attention

If the environmental movement was an infection, after my visiting 44 countries around the world, I can say the world has the environmental  flu!  (There is hope)

Site Background Information• Chester River Hospital Center 7.1 Acres

• Site development since 1935 as hospital

• Fuel Oil release discovered May 1991 (10,000 Gal. tank was empty over a weekend)…likely leaking for years

• Public Water supply well 850 ft. (259 m) down gradient, shut down until remediation system was installed

• Groundwater remediation system installed 1991

• 2012 Earth Data report indicated ≈ 83,452 Gal. (315,900 L) of LNAPL removed from site between 1991 to July 2012

• Initiation of MDE 12 month Closeout Monitoring July 2012 to June 2013, and the treatment system was shut off;

• Low levels of TPH (DRO) detected in June 2013 at Eight (8) of Seventeen (17) downgradient monitoring wells

• Pump & Treatment System Turned Back On!

• Stakeholder Concerns Started Mounting!

Treatment System Background• For over twenty (20) years CRHC’s focus was:

Remove liquid petroleum hydrocarbons (free product)

Remediate the groundwater using a “Pump and Treat” (P&T) system consisting of six (6) recovery wells, four (4) pre-filters (sediment and Fe), and two (2) MYCELXCELX®

filtration units, with discharge to storm sewer

• Later expanded to Seven (7) Recovery wells and present filtration/treatment system

• P&T System Designed for 100-120 Gallons of groundwater per minute (379 to 455 L/min) extraction rate requiring treatment (They have effective hydraulic control on-site)

Recall - 83,452 Gallons (315,900 L) of LNAPL product recovered between 1991 - July 2012

Mass Recovery Calculations Completed by EBA Engineering

SUMMARY• As a result of the investigations, analysis, and calculations of mass recovery the Technical Team 

determined that in the Push‐Pull wells recovery rates were significantly enhanced:

One thousand percent (1,000%) to Eighteen thousand percent (18,000%) TPH mass recovery

• Extrapolation:  Soil and groundwater remediation can be achieved using Ivey‐sol ‘Push‐Pull’ process, with 

‘Smear‐Zone’ targeting ability; Safe To Use – Minimal HS&E Concerns & Biodegradable; Easy to inject ‘Push’ and does not require pressure uses gravity feed (No chemical resistant 

equipment required) Effective for treating sorbed TPH in smear zone, including remaining NAPL Field Surfactant Testing – Allows Real Time Monitoring During the ‘Push’ and to minimized 

volume of groundwater extracted during the ‘Pull’ phase Effective Communication with stakeholders was paramount

• Full Scale: MDE approved full scale application in June 2015 (Priority Zone 1, 2, and 3 Remediation Approach) Started Full Scale Autumn of 2015
