Lead Service Lines in Greenwood, IN

What we know about lead in Greenwood's water system

Greenwood is served by 37 water systems that together provide water to approximately 869,724 people. The largest supplier is Indiana American Water – Northwest, which serves about 210,510 residents.

Lead enters drinking water primarily through lead service lines—pipes that connect homes to the main water line buried under the street. The water itself doesn't contain lead; the metal pipes do. When water sits in these pipes (especially overnight or after a few hours away), lead can leach into your tap water.

Currently, there are no known lead service lines reported in Greenwood's inventory data. However, this doesn't necessarily mean your home is lead-free. Inventories are still being completed across Indiana, and some water systems may not yet have full records of what's underground.

Why this matters for your home

Homes built before 1986 are more likely to have lead service lines, since lead pipes were common in older construction. Lead exposure is a real public health concern—it affects brain development in children and can cause other health problems—but it's also preventable with the right steps.

Your water utility is required by federal law to test their system and maintain records. If they've identified lead in their infrastructure, they must share that information with you and develop a plan to replace pipes.

How to find out about your specific home

Contact your local water utility directly. Ask them:

  • Does my address have a lead service line?
  • Do you have an inventory map I can check?
  • What's your timeline for testing or replacement?

The three largest utilities serving the Greenwood area are Indiana American Water – Northwest (serving 210,510 people), Indiana American Water – South Indiana (104,445), and Indiana American Water – Johnson County (86,813). If you're unsure which system serves your address, your water bill will show the utility name, or you can search by zip code on your utility's website.

Next steps for residents

  • Call your water utility and ask if your address has a lead service line or unknown material pipes.
  • Request their lead inventory map if available online or by mail.
  • Have your water tested through your utility or a certified lab if you're concerned (most utilities offer free testing).
  • Use a filter certified for lead reduction (NSF/ANSI Standard 53) while you investigate, especially if children under 6 live in your home.

Common questions

Does Greenwood have lead in the water?

No known lead service lines have been reported in Greenwood's current inventory data, but inventories are still being completed. The safest approach is to contact your specific water utility to ask about your address.

How do I know if my house has a lead service line?

Call your water utility and ask directly. They're required to maintain an inventory and can tell you if your address has lead pipes. You can also look at your water bill to find your utility's contact information.

Is it safe to drink tap water in Greenwood?

Greenwood's water meets federal safety standards, but lead service lines are a home-specific issue—they depend on the pipes connected to your individual property. If you're concerned, request testing from your utility or use a certified lead-reduction filter.

What should I do if my house has a lead service line?

Contact your utility about replacement programs or timelines. In the meantime, run water for 30 seconds before drinking, use cold water for cooking and drinking (hot water leaches more lead), and consider a certified lead-reduction filter.
