3 Ivey sol is an international award winning Remediation Technology Company, founded in 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) Source Pathway Receptor Model 2
4 How Old Is The Environmental Industry (a.k.a. Environmental Movement)? Who is older Me Vs. Environmental Industry? 45 to < 50 Years (+/ ) 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) What Is Water? Its Not H 2 O 3

(259 m) down gradient, shut down until remediation system was installed Groundwater remediation system installed 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! North Chestertown Wellhead Protection Area (Unconfined Aquifer) Site up-gradient and <850 Ft. From Town Production Wells 6
