That's a good point. Most people would be Ok with just purchasing a Water Test Kit found in most retail hardware stores like what was sold in Flint Michigan during their water issue. I have found these test kits unable to provide reliable answers and difficult to use.
The problem is that with municipal water it has to travel through an almost unknown amount pipe distance to reach your home. Depending on the age of the water system in your town these pipes can possibly be leaded. Federal regulation only requires that local water companies do periodic testing for metals, even if they are aware of lead pipes in the system. In my experience going to the water companies directly is arduous process at best. Most often you will have to repeatedly call them just to get your answers.
Personally, I would pay for a professional water analysis at least this give you the knowledge of what exactly you have coming out of your faucet.
Here's The EPA’s Safe Drinking Water Hotline, 800-426-4791. They have consistent and up to date list of state certified labs for testing the water in local area. Most general test are about $40.
Remember both the EPA and CDC say there is no level of lead that is safe to ingest.
