Zero-valent iron in both granular and injectable micron-scale is used as a reductant to treat chlorinated solvents and contaminants such as metals and many pesticides in groundwater, soils, and sediments.
Compass supplies both injectable zero-valent iron (also known as ZVI, metallic iron, Fe0) as well as granular ZVI for groundwater and soil remediation, as well as a variety of related applications, including treating mine water and lake/pond renewal. In Situ Chemical Reduction (ISCR) with zero-valent iron is advantageous as it is a safe, sustainable, and long-term treatment solution (between 3-15 years depending on the grade used as well as site conditions). Another important consideration in choosing ZVI is that production of harmful daughter products (DCE and VC) is minimized.
Compass offers zero-valent iron in multiple grades to meet the varying requirements of sites with different geological settings and contaminant profiles. As reactivity and longevity are dependent on surface area, particle size is a key factor in choosing which grade of ZVI powder to use for your site.
In addition to a standardized line of commonly used particle sizes, Compass can provide custom solutions to meet your site requirements. We have partnered with Peerless Metals to provide only the highest quality iron powders and all of our granular and injectable ZVI products are made in the USA. Because our ZVI comes from only a single source, you know you are always getting the highest quality zero-valent iron for your remediation projects.
