Iron in Texas well water
In Texas, iron was detected in 59% of 13,693 tested private well samples.
Iron is a nuisance rather than a health hazard: rust stains, metallic taste, and clogged fixtures above 300 ug/L. It often occurs with manganese and can feed iron bacteria that foul plumbing.
Check your iron number
Type the value from your lab report. It is compared to the EPA limit, the same way the full interpretation does it.
