The water leaving plants won't have high limits of lead, the plants will usually cut off supply than send out water over the PCV limits.
New houses are a lot less likely to have lead in the pipes, it's usually older systems where pipes may have rusted or degraded that would have higher lead levels.
If you are concerned about the levels of metals in the water, you can always take a sample from your tap and have it tested independently. There's a lot of places that could carry out this testing for you
