Iron Bac­te­ria in North­west Indi­ana Wet Basements

Iron Bacteria in Northwest Indiana Wet Basements

If you live in north­west Indi­ana, chances are you’re see­ing orange in your base­ment. Whether it’s a lot or just a lit­tle, whether it’s a stained floor around your water heater or sludge in your sump pump, it all comes from the same source – iron bacteria.

Iron bac­te­ria are harm­less bac­te­ria that are found almost every­where in our envi­ron­ment; they oxi­dize the iron in water to sur­vive and grow. The result­ing by-prod­uct of this oxi­da­tion is fer­rous oxide and that’s what cre­ates the orange/​brown stain and sludge.

Iron Bac­te­ria Can be the Cause of Wet Base­ments in North­west Indiana

It’s a good thing that iron bac­te­ria aren’t harm­ful to humans because there’s a lot of it in north­west Indi­ana. The soil in the area is par­tic­u­lar­ly rich in iron and the iron con­tained in the soil moves eas­i­ly into ground­wa­ter as it per­co­lates through the ground.

Because ground­wa­ter is the source of house­hold drink­ing water for more than half the state’s pop­u­la­tion and Indi­ana ranks 9th in the U.S. in the use of pri­vate wells, it’s not sur­pris­ing that north­west Indi­ana has an iron bac­te­ria prob­lem. Water from pri­vate wells is quite like­ly to car­ry iron bac­te­ria because it leeched from the soil sur­round­ing the aquifer.

Most of the time, the pres­ence of iron bac­te­ria and the result­ing iron oxide is mere­ly a nui­sance in your home. Base­ment floors, sump pumps and plumb­ing fix­tures may be stained orange; a good scrub­bing with a chlo­ri­nat­ed cleanser will take care of that.

The big prob­lem with iron bac­te­ria is that, in high con­cen­tra­tions, it cre­ates a gelati­nous orange sludge that can wreak hav­oc with base­ment water­proof­ing sys­tems. It can clog both inte­ri­or and exte­ri­or drain tile and gum up sump pumps. In this flu­id state, the iron bac­te­ria sludge can be removed by a base­ment water­proof­ing com­pa­ny using a hot-water flush that will kill the bac­te­ria and remove the sludge.

In dry con­di­tions, such as the drought the area expe­ri­enced this sum­mer, the gelati­nous mat­ter can dry out and solid­i­fy. If this hap­pens in the grav­el bed sur­round­ing drain tile, water can no longer flow through the grav­el and reach the drain. If it occurs inside the drain tile itself, flow will be blocked. Inside a sump pump, the sol­id mat­ter will ren­der it use­less. In any of these cas­es, the iron oxide can­not be removed and the sump pump, grav­el or drain tile must be replaced.

A base­ment water­proof­ing com­pa­ny expe­ri­enced in deal­ing with iron bac­te­ria in north­west Indi­ana can design water­proof­ing sys­tems to min­i­mize the risk of clog­ging. They can install clean-outs and mod­i­fy oth­er com­po­nents to lessen the like­li­hood of a prob­lem. Chlo­rine is anoth­er way of elim­i­nat­ing iron bac­te­ria and the base­ment water­proof­ing com­pa­ny can incor­po­rate it into a water­proof­ing system.

At U.S. Water­proof­ing we’ve helped many home­own­ers in places like Mer­ril­lville, Dyer and Val­paraiso keep their base­ments dry with­out invit­ing iron bac­te­ria along for the ride. If you’d like to know how we can do that for your home, please ask for a free con­sul­ta­tion.
