Mississippi – The Magnolia State – Water Quality Report 2025: PFAS Testing, Infrastructure Concerns & Safety across your state
Mississippi’s water infrastructure serves approximately 2.9 million residents across a diverse geographical region, from the fertile Mississippi Delta in the northwest to the Gulf Coast in the south. The state operates through over 1,000 public water systems, ranging from large municipal utilities to small rural systems providing essential services to underserved communities. Mississippi’s water sources include the mighty Mississippi River, Yazoo Basin, Tennessee-Tombigbee Waterway, and numerous groundwater aquifers that supply both urban centers and agricultural areas.
Despite abundant water resources, Mississippi faces severe infrastructure challenges. According to the American Society of Civil Engineers’ 2024 Infrastructure Report Card, Mississippi’s drinking water infrastructure received a D- grade – down from a D in 2020 – highlighting critical aging systems, funding shortfalls, and emerging contaminant concerns including PFAS “forever chemicals.” The state has received over $33.9 million in federal infrastructure investments from the Biden-Harris Administration’s Bipartisan Infrastructure Law to address these challenges, focusing on drinking water safety, wastewater treatment upgrades, and emerging contaminant removal. Mississippi’s commitment to water quality improvement is demonstrated through partnerships between the Mississippi Department of Environmental Quality (MDEQ), local utilities, and federal agencies working to ensure safe, reliable water access for all residents.

- PFAS Contamination Crisis: Consumer Reports testing revealed 98% of Mississippi water samples contained PFAS, with 23 counties showing levels above the recommended maximum of 10 parts per trillion.
- Federal Infrastructure Investment: Over $33.9 million in federal funding through the Bipartisan Infrastructure Law has been allocated to Mississippi for water infrastructure improvements, though this represents only 10% of estimated $8 billion in needed repairs.
Major Water Sources and Challenges
- Mississippi River System: Primary source for multiple Gulf Coast communities, with documented PFAS contamination at five sites stretching from Pointe Coupée Parish to St. James Parish requiring ongoing monitoring.
- Jackson Water Crisis: The state capital’s water system faces chronic failure with aging infrastructure requiring an estimated $2 billion for full repair, currently under federal management through JXN Water.
- Rural System Fragmentation: Small water systems struggle with disproportionate challenges including aging infrastructure, limited technical capacity, and higher per-capita costs for regulatory compliance.
Emerging Contaminant Response
- PFAS Regulation Implementation: New EPA drinking water standards for PFOA and PFOS (4 parts per trillion) take effect in 2029, requiring significant infrastructure investments from affected water systems across the state.
- Statewide PFAS Monitoring: MDEQ is evaluating industrial and commercial PFAS usage and reviewing common areas of concern including landfills, fire training facilities, and wastewater treatment plants.
- Military Site Contamination: Multiple military installations including Naval Construction Battalion Center Gulfport are under investigation for PFAS contamination from firefighting foam use dating back to the 1960s.
Rural and Disadvantaged Communities
- Systemic Infrastructure Failures: One in three sewer systems statewide have violated pollution limits in the past year, with rural systems facing the greatest challenges in meeting compliance requirements.
- State Funding Programs: The Mississippi Municipality & County Water Infrastructure Grant Program provided $450 million in matching funds to eligible entities for water, wastewater, and stormwater infrastructure improvements.
- Technical Assistance Programs: MDEQ provides enhanced technical support to help smaller systems navigate complex regulatory requirements, though enforcement challenges persist due to limited state resources.
Looking Forward: 2025-2030
Mississippi’s water quality landscape faces unprecedented challenges as utilities prepare for new federal PFAS regulations taking effect in 2029. The state’s deteriorating drinking water infrastructure grade reflects the urgent need for sustained investment and improved management. While federal infrastructure funds provide critical support, addressing Mississippi’s estimated $8 billion in water infrastructure needs will require innovative financing, regional cooperation, and sustained political commitment. The Jackson water crisis serves as a stark reminder of the consequences of decades of deferred maintenance and inadequate investment. Successful transformation will demand continued collaboration between state regulators, federal agencies, water utilities, and communities to ensure that all Mississippians have access to safe, affordable drinking water while addressing the legacy of industrial contamination and systemic infrastructure failures that have historically challenged the state’s water systems.
Recommendations for Mississippi Residents
Know Your Water Source
Contact your water utility to request annual water quality reports and ask about PFAS testing results. Visit MDEQ’s website to access your local system’s testing data and understand any contaminants of concern in your area.
Support Infrastructure Investment
Stay informed about local water infrastructure needs and support utility rate structures that enable necessary improvements. Attend public meetings when utilities discuss infrastructure upgrades and PFAS treatment investments.
Consider PFAS-Certified Filtration
Given widespread PFAS contamination, consider NSF-certified activated carbon or reverse osmosis filters specifically tested for PFAS removal. These can provide additional protection while utilities implement treatment upgrades.
Report Water Quality Concerns
Contact your local water utility immediately for taste, odor, or color concerns. Report suspected contamination to MDEQ’s Environmental Compliance Division at (601) 961-5171 for investigation and follow-up.
Practice Water Conservation
Support Mississippi’s water sustainability by implementing conservation measures like efficient irrigation, rainwater harvesting, and low-flow fixtures. Reducing demand helps utilities maintain system reliability and affordability.

Frequently Asked Questions
Is Mississippi’s tap water safe to drink?
Water safety varies significantly across Mississippi’s 1,000+ water systems. While some systems meet federal standards, nearly 60% have committed violations in recent years.
Consumer Reports testing revealed that 98% of Mississippi water samples contain PFAS “forever chemicals,” with 23 counties showing levels above recommended safety thresholds. Many rural systems also struggle with aging infrastructure and high water loss rates. The Jackson water crisis exemplifies the challenges faced statewide. Residents should review their utility’s annual water quality report, stay informed about local conditions, and consider certified filtration systems where PFAS contamination is documented.
What caused the Jackson water crisis?
Jackson’s water crisis resulted from decades of deferred maintenance, inadequate investment, and aging infrastructure in Mississippi’s capital city.
The city’s water system faces multiple challenges including pipes that are over 100 years old, water loss rates exceeding 40%, and chronic understaffing. Heavy rains in August 2022 overwhelmed the failing O.B. Curtis Water Treatment Plant, leaving 180,000 residents without reliable water service. The crisis required federal intervention and $600 million in emergency funding. Jackson is now under federal management through JXN Water, with an estimated $2 billion needed for full system repair.
