Although your drinking water is not usually a concentrated lead source like paint, it can still pose risks to you and your family. Those at the greatest risk, even with short-term exposure, are young children and pregnant women. Lead in drinking water can be a problem for infants whose diet consists of liquids, such as baby formula made with water. Never use water with high lead levels (more than 15 ppb) to mix into infant formula. It can severly impair a child's development, resulting in learning disabilities or stunted growth. Exposure for adults primarily affects the peripheral nervous system and can cause impairment of hearing, vision, and muscle coordination. Lead is also toxic to the blood, kidney, heart, and reproductive system.
Lead can enter your water from several points: Old buried lead pipes that connect your house to the water main (service lines), lead pipe connectors, lead-soldered joints in copper plumbing, and Chrome-plated faucets are generally made of brass, which contains 3 to 8 percent lead.
In some private wells, underwater pumps with brass fittings can cause elevated lead concentrations in drinking water, especially with new pumps and soft water. Contamination can occur when water comes in contact with these fixtures.
When water stands in lead pipes or plumbing systems containing lead for several hours or more, the lead may dissolve into your drinking water. This means the first water drawn from the tap in the morning, or later in the afternoon after returning from work or school, can contain fairly high levels of lead.

I want to thank you for the home inspection you did for us at 144 Avis Ave. in Dracut MA. We did not get the house because the home owners did not want to split the cost of fixing that wall. I had gotten two estimates, one from a landscaper and one from a Mason. Both gave an estimate of $15,000.00, for which I am grateful for your inspection and pointing out the wall problem. It would of been an undue burden on us, not to mention I am also grateful about the radon testing also. I just got the results today and they came back at 7.5 and 8.4, so that would of been another expense. I do hope that when we find a new house that you will be able to do our home inspection. Your fee was a drop in the hat, to what it would of cost us to fix the wall and then the cost of venting the basement. My husband was also very impressed with your report and how well it was written. Just wanted to drop you a line to let you know what happened, and hopefully will be doing business with you again very soon.
Have a Good Day
