OUR HISTORY TIMELINE
-
Foundation of IER
1997In 1997, Dick Handley created Inland Environmental Resources (IER) in order to provide local manufacturing and supply of environmentally-friendly Magnesium Hydroxide products for the Pacific Northwest.
-
Primary market and product development
1999IER's primary market was the specialty potato industry that had recently changed from a lye peeling process to the use of steam, resulting in a wastewater stream that flipped from being highly alkaline to slightly acidic.
After a few years of product development and on-site testing, it was found that Magnesium Hydroxide provided the most cost-effective and safe option for boosting the pH while also providing polymer reduction and sludge reduction. -
A growing team
2004Dr Doug Kelley is added to the team to spearhead product quality improvements and sales growth. At the time, Doug had small children who asked what he did; his response was simply that “we help folks clean their water after they use it”.
-
Rapid expansion
2016Within a few years, IER expands operations to include five manufacturing plants stretching from the Pacific Northwest to Lake Michigan across the northern tier states and Canada.
-
Acquisition
2019In 2019, IER was purchased by Calix Australia, with plans to further expand the offerings and markets for continued IER growth.
