Don’t misread thisA city-wide result does not tell you your tap result
A reported city-wide lead concentration is not a measurement of the water coming from every household tap. Lead can enter water through service lines, faucets, fixtures and plumbing materials.
Lead was not detected in CITY OF ELGIN's most recent lead sampling (2022–2024): the 90th-percentile result was below the lab's reporting limit. It comes from sampled homes; your own pipes decide what reaches your tap.
Does Elgin have lead service lines?+
In EPA's service line inventory (2026Q2), CITY OF ELGIN reported 1 lead service lines, 15 galvanized lines requiring replacement and 0 of unknown material, out of 4,389 lines in total.
Can my home have more lead than the city report shows?+
Yes. Lead usually enters water from service lines, solder and fixtures between the main and your tap, so one home can measure higher than the citywide figure. Only a test of your own tap shows it.
How do I know if my home has a lead service line?+
Ask CITY OF ELGIN whether your address appears in its service line inventory, which utilities must publish. You can also look where the water pipe enters your home: lead pipe is dull grey, soft, and shows shiny metal when scratched gently.
How do I test my Elgin tap water?+
Use a state-certified lab for an exact number, or a screening kit for a quick range. For lead, take a first-draw sample: water that has sat in the pipes for at least six hours.
What filter removes lead from Elgin water?+
One whose current certification names lead for the exact model: NSF/ANSI 53 (carbon) or NSF/ANSI 58 (reverse osmosis). Until then, run the cold tap for a few minutes after water has sat for hours, and use only cold water for drinking and cooking.
What certification should I look for in a lead filter?+
NSF/ANSI 53 or 58 with lead listed for the exact model, checked in the certifier's listing (NSF, WQA or IAPMO).
Should I replace my lead service line?+
If your home has one, replacing it removes the main source of lead. Ask CITY OF ELGIN first: it reported 1 lead and 15 galvanized service lines to replace in EPA's inventory (2026Q2), and many utilities replace these lines for free or share the cost.
