Last comments for you. Excerpts from the water quality report follow:   In terms of the pH and hardness of the water, I'd feel better if the pH of the water was closer to 8 and the mineral hardness was higher- these would potentially impart more scale forming ability to the water and potentially lessen probability of lead in service lines leaching into your water. That said, it is what it is. You're slightly better off in this regard if you AREN'T served by the Baxter plant. But overall it looks like your water utility delivers an ok product when compared to other reports I've seen. Follow their guidance in the letter to attempt to verify your service line material type. Implement personal protective measures (water filter, etc.) as appropriate thereafter. Under the "More you can do" section of your letter, review the references for service line replacement if necessary and discuss with your landlord if you're renting. Most cities that have lead service line problems also have funding mechanisms in place to assist with replacement costs. Good luck.
