Lead Service Lines in Brookings, SD

What you need to know

Brookings serves about 23,600 people through four public water systems. The largest is Brookings Municipal Utilities, which supplies water to roughly 23,400 residents.

Lead enters drinking water primarily through lead service lines—the pipes that connect the main water line under the street to your home. Lead can also leach from brass fittings, solder, and other components in older plumbing. The good news: lead is preventable. With the right information and simple steps, you can protect your family.

Lead service line inventory status

South Dakota water utilities are required to develop and update inventories of lead service lines in their systems. Brookings Municipal Utilities has not yet reported confirmed lead service line counts to the EPA. This doesn't mean there are no lead lines—it means the data is either still being collected, under review, or not yet publicly available.

The smaller systems serving University Estates (150 people), North Brookings Water and Sanitary District (48 people), and Southbrook Estates (28 people) also have not reported confirmed lead line inventories.

What to do now

Contact your water utility directly. They can tell you:

  • Whether your specific address has a known lead service line
  • What they've found so far in their inventory work
  • What water quality testing or treatment programs they offer

For Brookings Municipal Utilities, reach out through their official website or customer service line. For the smaller systems, contact your local water district office.

Testing your water

If you're concerned about lead, a simple water test can tell you what's actually in your water right now. Your water utility may offer free or low-cost testing. The EPA also provides guidance on certified labs.

Lead levels can vary depending on how long water has sat in your pipes, water temperature, and pipe condition. If results show elevated lead, your utility can suggest next steps—which may include flushing lines, installing a certified filter, or replacing pipes.

Health and next steps

If you have young children or are pregnant, lead exposure is worth taking seriously. The CDC recommends testing children's blood lead levels if there's any possibility of exposure. A pediatrician can assess individual risk and recommend testing.

Next steps for residents

  • Contact Brookings Municipal Utilities to ask about lead service line inventory results and water testing options.
  • Request a water test if your home was built before 1986 or if you don't know your service line material.
  • Talk to your pediatrician if you have children under 6 and want to discuss lead exposure risk.
  • Visit the EPA's lead and copper rule page for more information on treatment and testing standards.

Common questions

Does Brookings South Dakota have lead in the water?

Lead service line inventory data for Brookings has not yet been reported publicly. The best way to know if your home is affected is to contact Brookings Municipal Utilities and ask about your specific address, or have your water tested.

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

Your water utility can check their records for your address. You can also look at the pipe connecting to your home's water meter—lead is soft, dull gray, and leaves a mark if you scratch it with a coin. A plumber can also identify it.

Is lead in water dangerous for kids?

Lead can affect brain development in young children even at low levels. If you're concerned, talk to your pediatrician about testing your child's blood lead level. The CDC and your local health department have resources on reducing exposure.

Can I remove lead from my tap water?

Yes. Certified water filters, reverse osmosis systems, and distillation can reduce lead. Your water utility can recommend which option works best for your water. Some utilities offer rebates or assistance programs.
