Shreveport – Louisiana – Water Quality Report 2025: PFAS Testing, Infrastructure Concerns & Safety across your city
Shreveport Water & Sewerage provides comprehensive water services to approximately 177,000 residents in northwest Louisiana’s largest city, serving as a critical municipal utility for Caddo Parish and surrounding areas. The system operates through an extensive network of distribution lines, storage facilities, and the Thomas L. Amiss Water Treatment Plant, delivering millions of gallons of treated water daily to Louisiana’s third-largest city and its metropolitan area.
Shreveport sources its drinking water primarily from Cross Lake, a 8,775-acre reservoir located within the city limits that serves both as the municipal water supply and recreational asset. During dry periods, Cross Lake is supplemented with water pumped from Twelve Mile Bayou. The water undergoes comprehensive treatment at the T.L. Amiss Water Purification and Pumping Station, which utilizes advanced ozone treatment technology alongside traditional filtration and disinfection processes. However, Shreveport’s water system has faced significant challenges in recent years, receiving a D grade (revised from F) from the Louisiana Department of Health for 2024 due to infrastructure deficiencies, customer service issues, and water quality concerns including elevated manganese levels that caused widespread water discoloration throughout 2024.

- Watershed Management: The city employs full-time Environmental Control Officers who patrol Cross Lake and surrounding watershed to monitor potential pollution threats and manage invasive species like giant Salvinia and hydrilla.
Treatment Technology
- T.L. Amiss Water Treatment Plant: The primary treatment facility employs ozone treatment, coagulation, flocculation, sedimentation, and filtration processes, though the plant was not originally designed to handle elevated manganese levels experienced in 2024.
- Ozone Treatment System: Advanced ozone technology serves as a powerful oxidation treatment for metals and minerals, though system failures in December 2022 through early 2023 led to temporary reliance on increased chlorine disinfection.
- Manganese Treatment Challenges: The 2024 manganese crisis revealed limitations in the current treatment system’s ability to handle high mineral content, leading to water discoloration and taste issues despite safety compliance.
Infrastructure Modernization
- 2024 Bond Improvements: Voter-approved bond funding supports replacement of two major transmission lines handling 60% of the city’s water supply, treatment plant upgrades, and construction of a new strategically-located water tower.
- Regulatory Compliance: The city has allocated over $10 million to address infrastructure deficiencies identified in 2021 state inspections, with an additional $40 million in bond-funded projects planned for system improvements.
- Water Storage Improvements: Ongoing rehabilitation of existing water towers and emergency generator installations to ensure system reliability during power outages and peak demand periods.

Frequently Asked Questions
Is Shreveport’s tap water safe to drink?
Yes, Shreveport’s tap water is safe to drink when not under a boil advisory, according to both city officials and the Louisiana Department of Health. The water comes from Cross Lake and undergoes comprehensive treatment at the T.L. Amiss Water Treatment Plant.
While Shreveport’s water system received a D grade (revised from F) from the state for 2024, these grades reflect infrastructure and management challenges rather than immediate health risks. The Louisiana Department of Health confirms that a poor water system grade does not imply unsafe water and that water systems are required to notify customers immediately when drinking water becomes unsafe.
What caused the brown water in 2024?
The brown water discoloration throughout 2024 was caused by elevated manganese levels in Cross Lake that reached historic highs:
1. Heavy spring rains likely stirred up manganese-rich sediment from the lake bottom
2. Cross Lake manganese levels peaked at 1.29 mg/L in June 2024 – more than ten times the EPA’s aesthetic guideline
3. The current treatment plant was not designed to handle such high manganese concentrations
While manganese causes discoloration and taste issues, it is not considered a health hazard at the levels detected. The city has since implemented enhanced treatment protocols and is investing in improved manganese removal capabilities.
Why did Shreveport get a poor grade?
Shreveport received a D grade (65/100) from the Louisiana Department of Health for 2024 (revised from an initial F grade) based on seven criteria:
