Martis Valley Water System Lead and Copper Rule Statement

The Northstar Community Services District (NCSD) has completed the initial lead service line inventory required by U.S. EPA’s Lead and Copper Rule Revisions for the Martis Valley Water System. The deadline for the initial inventories was October 16, 2024. 

Through completing a historical records review and field investigations, NCSD has determined it has no lead or galvanized requiring replacement service lines in its distribution system. This includes any privately-owned or customer-owned service lines.

NCSD reviewed all applicable sources of information, including 

• All construction and plumbing codes, permits, and existing records or other documentation which indicates the service line materials;
• All water system records, including distribution system maps and drawings, historical records on each service connection, meter installation records, historical capital improvement or master plans, and standard operating procedures; 
• All inspections and records of the distribution system that indicate service line material, including inspections conducted during the course of normal operations (e.g., checking service line materials when reading water meters or performing maintenance activities); and 
• All previous service line or meter replacements were conducted.  

All service lines inspected were verified as non-lead, normally made of copper or plastic. No lead or galvanized requiring replacement service lines were identified. 

NCSD continues to document service line material information obtained from normal operations, such as service line maintenance or water meter readings, after October 2024 and will update the initial inventory accordingly.
