Key facts for Louisiana
- Louisiana systems had to submit initial inventories covering both utility-owned and customer-owned service line portions by October 16, 2024. ([ldh.la.gov](https://ldh.la.gov/bureau-of-engineering-services/LSLI?utm_source=openai))
- LDH says replacement plans due by November 1, 2027 must include a funding strategy for customers unable to pay for their portion. ([ldh.la.gov](https://www.ldh.la.gov/bureau-of-engineering-services/LSLI?utm_source=openai))
- LDH says Louisiana is eligible for over $42 million per year for three years for lead service line identification and replacement. ([ldh.la.gov](https://ldh.la.gov/bureau-of-engineering-services/lcrrlcri-rulemaking-overview?utm_source=openai))

What to do next
- Check your address on your utility’s official inventory page or map first; Louisiana utilities must classify both sides of the line. ([ldh.la.gov](https://ldh.la.gov/bureau-of-engineering-services/LSLI?utm_source=openai))
- If your utility identifies lead, GRR, or unknown material, ask whether it has adopted a replacement funding strategy or applied for LDH/SRF lead-line funds. ([ldh.la.gov](https://www.ldh.la.gov/bureau-of-engineering-services/LSLI?utm_source=openai))
- If you are in New Orleans, use SWBNO’s official page to request a test kit or lead-filter pitcher while replacement planning continues. ([test1.swbno.org](https://test1.swbno.org/Projects/LeadAwareness))
