How does lead get into drinking water?
Lead is seldom found as a natural contaminant in drinking water and generally originates from lead-based plumbing materials. Lead can enter drinking water when plumbing materials containing lead corrode over time. These materials include pipes made of lead, lead-based solder used to join copper pipe, and brass and chrome-plated brass faucets. Lead service lines are typically the most significant source of lead in the water. In Florida, these materials are more likely to be found in homes built before 1991.

If a service line constructed with lead is identified on my property and then replaced, how can you ensure there is no longer lead in my water?
Following replacement, residents can request water quality tap sampling between 3 to 6 months after replacement to ensure lead levels are below 10 parts per billion (ppb).
If there are lead-based materials in my service line or premise plumbing, what steps can I take to reduce lead exposure?
Refer to the Lead Reduction Steps flyer for information on steps that can be completed to reduce lead exposure.
Do all lead service lines contaminate drinking water?
Not necessarily. All lead service lines have the potential to leach (release) lead into drinking water, but the City carefully manages the water chemistry in the distribution system to prevent this. The City also operates an EPA approved corrosion control procedure (addition of a corrosion inhibitor to the water entering the distribution system), which forms a protective layer on the pipe to help prevent the release of lead. Lead leaching can occur when an EPA approved corrosion control procedure is not used or optimized, which can result in the corrosion of distribution system materials and release of lead.
If a service line constructed with lead is identified on my property and then replaced, how can you ensure there is no longer lead in my water?
Following replacement, water quality sampling will be conducted to ensure lead levels are below 10 parts per billion (ppb). As an additional protective measure, customers will receive a point of use pitcher filter that is certified for lead and particulate removal and flushing instructions for residents to perform inside the homes to be done after service line replacement. Flushing of the line will also be done in the ROW after each replacement performed in the ROW.

Why is it necessary for me to self-report the material of my service line?
The portion of the water service line between your water meter and your home was not installed by the City. That portion of the water service line was likely constructed in accordance with Florida Plumbing Requirements, which as of 1990 did not include lead as an approved service line material. The Lead and Copper Rule Revision requires an inventory of the entire service line, including the portion owned by the customer. By validating the material of your service line, you are helping to comply with the regulation as well as identifying any outdated service line materials.
Are all residential, commercial, and industrial property owners being asked to complete the survey?
No, only locations where the service line material is still unknown are asked to complete the survey.
How do I know if my service line material is unknown or needs confirmation?
The City is reaching out and sending letters to those customers where service line material is unknown. Service line material can be seen in the Water Service Line Inventory Map web page.
How do I determine what material my water service line is made of?
Instructions for identifying your service line material can be found here: Service Line Material Identification
What will the City do with the survey results?
The City will validate the service line material self-reported by the resident. Validated service line material information will be added to the inventory submitted to the Florida Department of Environmental Protection (FDEP), as required by the USEPA. Service lines constructed of outdated materials will be flagged for replacement.
Will my personal information be shared?
No. Personal information will not be shared. Only public information regarding your service line material will be published to the Water Service Line Inventory Map web page and submitted to EPD, as required by the USEPA. This information includes the verified service line material, date of construction, and physical address. Responses will only be used for the purpose of complying with the Lead and Copper Rule Revisions.
Can I find my service line material information on an inventory from another site other than the Water Service Line Inventory Map website?
City of Miami Beach customers should be aware that other sources of service line materials, including maps or inventories on other sites, could use outdated and incorrect information. The inventory on the City of Miami Beach website is the most accurate representation of service line material data in the City of Miami Beach distribution system.
