Lead can enter water after it leaves the treatment plant because the service line or household plumbing contains lead-bearing materials.


Lead in drinking water often comes from lead service lines, plumbing, solder or fixtures rather than the source water itself. EPA identifies lead service lines as a major source where they are present, and RIDOH provides a Rhode Island service-line transparency tool.

Lead can enter water after it leaves the treatment plant because the service line or household plumbing contains lead-bearing materials.
Knowing the pipe material helps assess risk, but it does not tell you the lead concentration at a specific faucet.
| Question | Best next step |
|---|---|
| Do I have a lead or unknown service line? | Check your water utility / RIDOH service-line information |
| Is lead actually in my tap water? | Use appropriate laboratory testing |
| How do I reduce exposure while investigating? | Follow EPA/RIDOH guidance on flushing, cold water, aerator cleaning and certified filters |
| What treatment can help? | Use a device with a verified lead-reduction claim for the intended faucet/use |
EPA notes that boiling does not remove lead and recommends measures such as cold water for drinking/cooking, aerator cleaning, flushing stagnant water and certified filters where appropriate. Source: EPA lead guidance.
AquaTrust’s free screening does not test lead. Use the appropriate laboratory test first, then decide where treatment fits alongside plumbing or service-line correction.
AquaTrust can help with treatment after the lead source and result are understood.
