Does Wylie have lead service lines?+
In EPA's service line inventory (2026Q2), CITY OF WYLIE reported 0 lead service lines, 14 galvanized lines requiring replacement and 0 of unknown material, out of 13,186 lines in total.
How much lead was detected in Wylie water?+
1.03 µg/L at the 90th percentile of the homes CITY OF WYLIE sampled under the Lead and Copper Rule (2025).
Is Wylie's lead level below the legal limit?+
It is below the 15 µg/L federal action level. Lead has no MCL: the action level is a treatment trigger, and EPA's health goal for lead is zero.
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 WYLIE 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 Wylie 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 Wylie 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 WYLIE first: it reported 14 galvanized service lines to replace in EPA's inventory (2026Q2), and many utilities replace these lines for free or share the cost.
