State-Specific Resources


How Can You Get Started on the Path to Compliance?

Step 1: Get On The Funding List

Estimate your potential cost to create the inventory including:

More requests than money available means grant eligibility is required.

Step 2: Create a List of Every Service Line

  • Make sure you know the location of every single line in your system
  • Compare your billing database
  • Create a spreadsheet with one row for each service line
  • And/Or update your GIS to include a node for each
  • Identify which lines have private components and which do not

Step 3: Create a Method For Collecting Field Information

You are required to collect information during normal operations:
  • Normal repair and replacement actions on mains, service lines, and meters
  • Backflow inspections
  • Meter reads
  • Customer call outs
  • Sampling stops
  • Valve box inspections
Need to develop a way to capture this information; cannot rely on anecdotal description.

Step 4: Collect and Review Historical Records

You cannot rely on memory and interviews, you need to document.
Examples of Historical Records:
  • Distribution Maps and Record Drawings
  • Historical Construction and Plumbing Codes
  • Maintenance Records
  • Historical Documentation – Tap Cards
  • Capital Improvements and Master Plans
  • Meter Installation Records
  • Standard Operating Procedures
  • O & M Manuals
  • Inspection Records
  • Permit Files

Step 5: Determine the Construction Date of Lines

  • Does not have to be exact
  • Can use development records
  • County records
  • Tax records

Step 6: Collect Private Line Information

Ask for help – survey your residents.
What to consider:
You can perform a scratch test. Lead is dull, very soft, and will turn a shiny silver color when scratched.
You can also perform a magnet test. Magnets will ONLY stick to steel. They will not stick to lead or copper.

Step 7: Evaluate Gaps For Investigation

If the Gaps are Greater Than What You Can Accomplish, Take a Targeted Approach
  • Likelihood – Disadvantage areas and areas with children are more likely need to be addressed.
  • Environmental Justice – Pay attention to environmental justice requirements.

Predictive Modeling Can Help With Large Systems

Step 8: Validate and Investigate

Validate Customer Responses. Validate Historical Records.
  • Visual inspection during normal operations
  • Water quality samples cannot rule out, only confirm lead
  • Potholing requires vac-truck
  • Excavation most disruptive
