opportunity to talk about climate change, particularly Canada’s
contribution to global greenhouse gas emissions.

to immobilize the lead in situ to limit the migration of groundwater plume. This was

stable sulfides. Baseline conditions were relatively toxic with a DO of two to six ppm

EHC-M for in situ immobilization of lead
Metallic lead is only stable at very low redox potentials and from slightly acidic to
extremely basic pH conditions. As a result, Pb is often converted into other oxidized
forms (e.g., hydrocerussite [Pb3(CO3)2(OH)2], cerussite [PbCO3], PbCO3, PbSO4 and 1-888-4Refuel www.4refuel.com

tween pH 7.7 and 10, while cerussite is stable between pH six and 7.7. However, the
stability ranges of Pb3(CO3)2(OH)2 and PbCO3 will differ due to variations in thermody-
namic constants and total soluble Pb concentration.
EHC-M combines controlled-release carbon, ZVI and a slow-release source of

Ontario would provide Menova

Wal-Mart Canada would provide
up to $3 million to support the testing
