Test first

Plumbing inside a home can add lead the record can’t show.

A tap test tells you what reaches your glass. If lead is a concern, these carry a lead reduction claim:

Does Montclair have lead service lines?

In EPA's service line inventory (2026Q2), MONTE VISTA WD reported 0 lead service lines, 0 galvanized lines requiring replacement and 0 of unknown material, out of 12,657 lines in total.

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

Ask MONTE VISTA WD 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 reduce lead in my water?

Run the cold tap for a few minutes after water has sat for hours, use only cold water for drinking and cooking, and use a filter certified to NSF/ANSI 53 for lead reduction. Replacing a lead service line removes the main source.
