Sampling and analysis of iron ocher
Sampling and analysis of iron ochre
Have you noticed a reddish gelatinous buildup in a foundation drain? It could be an iron ocher problem. This poses a serious threat to air quality and to the health of occupants, as it can result in basement flooding, excessive humidity and, consequently, the appearance of mold.
Ferrous ocher is a deposit of iron hydroxide caused by ferruginous bacteria in the water table. When the conditions are optimal for its formation, iron ocher can take up a lot of volume and clog drains, then proliferate in catchment basins and around pumps. Ferrous ocher is found as a gelatinous and viscous mass of reddish color. Ocher can be formed in two ways: chemically or biologically.
The biological process is the fastest and generally results in larger accumulations. The chemical process is slower and rarely causes an accumulation problem.
