Rhode Island – The Ocean State – Water Quality Report 2025: PFAS Testing, Infrastructure Concerns & Safety across your state
Rhode Island’s compact water infrastructure serves approximately 1.1 million residents across the nation’s smallest state, from the Providence metropolitan area to coastal communities along Narragansett Bay. The state operates through 66 public water systems, with Providence Water as the largest utility serving over 600,000 residents across more than a dozen communities. Rhode Island’s primary water sources include the Scituate Reservoir system, which provides about 60% of the state’s drinking water, along with smaller reservoirs and groundwater aquifers that supply both urban centers and coastal communities.
Despite its small size, Rhode Island faces significant water quality challenges. According to recent infrastructure assessments, the state’s drinking water infrastructure requires substantial investment to address aging systems and emerging contaminants. Rhode Island has received over $187 million in federal infrastructure investments from the Biden-Harris Administration’s Bipartisan Infrastructure Law since 2022, including $10 million specifically to investigate and address local PFAS contamination. The state’s proactive approach to PFAS regulation is demonstrated through comprehensive legislation passed in 2022 and 2024, establishing some of the nation’s most stringent standards for “forever chemicals” in drinking water and consumer products.
Rhode Island Water Quality: Current Status (2024-2025)
Statewide Compliance and Testing
- Overall Compliance: The majority of Rhode Island’s 66 public water systems meet federal Safe Drinking Water Act standards, though 11 systems have exceeded the state’s PFAS limit of 20 parts per trillion, with one system requiring a “do not drink” notice for levels above 70 ppt.
- PFAS Leadership: Rhode Island has emerged as a national leader in PFAS regulation, establishing the strictest state drinking water standards in the nation at 20 ppt for six PFAS chemicals, significantly lower than federal guidelines.
- Infrastructure Investment: Over $187 million in federal funding through the Bipartisan Infrastructure Law has been allocated to Rhode Island since 2022, including $10 million for PFAS research and $6.4 million for lead service line replacement.
Major Water Sources and Challenges
- Scituate Reservoir System: Provides approximately 60% of Rhode Island’s drinking water through Providence Water, serving the state’s largest population centers with comprehensive treatment and monitoring programs.
- Coastal Vulnerability: Rhode Island’s extensive coastline faces challenges from sea-level rise and saltwater intrusion into freshwater aquifers, requiring enhanced monitoring and protection measures.
- Infrastructure Modernization: Many water systems require upgrades to address aging infrastructure, with Providence Water implementing extensive capital improvement programs for pipe replacement and system reliability.
PFAS Contamination Response
- Comprehensive PFAS Regulation: Rhode Island’s drinking water standards for six PFAS chemicals at 20 ppt are among the most protective in the nation, requiring quarterly monitoring for systems exceeding limits.
- Source Identification: Six major PFAS contamination sources have been identified including Department of Defense sites, fire stations, textile mills, and Superfund sites, with targeted remediation efforts underway.
- Consumer Product Bans: Rhode Island passed comprehensive PFAS bans in 2022 and 2024, prohibiting these chemicals in food packaging, firefighting foam, cosmetics, cookware, and other consumer products to prevent future contamination.
Small and Disadvantaged Communities
- Targeted Support: The University of Rhode Island Water Quality Program is conducting a $1.5 million study focusing on PFAS contamination in two pilot communities to develop best practices for treatment and public engagement.
- Technical Assistance: Enhanced support is available through the Rhode Island Department of Health and EPA to help smaller systems navigate complex PFAS regulations and secure funding for necessary improvements.
- Lead Service Line Replacement: Providence Water received $6.4 million in federal grants to assist disadvantaged neighborhoods with private lead service line replacement, protecting vulnerable populations from lead exposure.
Looking Forward: 2025-2030
Rhode Island’s water quality landscape is being transformed through some of the nation’s most aggressive PFAS regulations and substantial federal infrastructure investments. The state’s comprehensive approach to addressing emerging contaminants, combined with ongoing infrastructure modernization efforts, positions Rhode Island as a national model for protecting public health. However, successful implementation will require continued collaboration between state regulators, water utilities, and communities to ensure that all Rhode Islanders have access to safe, affordable drinking water while addressing the challenges of aging infrastructure, coastal vulnerability, and legacy contamination that continue to impact the Ocean State’s water systems.
Recommendations for Rhode Island Residents
Know Your Water Source
Contact your water utility to request annual water quality reports and ask about PFAS testing results. Visit the Rhode Island Department of Health’s Water System Information portal to access your local system’s testing data and compliance status.
Support Infrastructure Investment
Stay informed about local water infrastructure needs and support utility rate structures that enable necessary improvements. Participate in public meetings when utilities discuss infrastructure upgrades and PFAS treatment investments.
Consider PFAS-Certified Filtration
For areas with known PFAS contamination above 20 ppt, 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 the Rhode Island Department of Health at (401) 222-6867 for investigation and follow-up.
Practice Water Conservation
Support Rhode Island’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 Rhode Island’s tap water safe to drink?
Most of Rhode Island’s public water systems meet federal drinking water standards and are safe for consumption. However, 11 systems currently exceed the state’s strict PFAS limit of 20 parts per trillion.
The Rhode Island Department of Health requires comprehensive testing across all 66 public water systems. Rhode Island has the most protective PFAS drinking water standards in the nation, significantly stricter than federal guidelines. Water utilities are implementing advanced treatment technologies and the state has received over $187 million in federal funding since 2022 to address emerging contaminants and infrastructure needs. Residents should review their utility’s annual water quality report and stay informed about local conditions.
What makes Rhode Island’s PFAS standards different?
Rhode Island has established the nation’s most protective PFAS drinking water standards at 20 parts per trillion for six chemicals, significantly lower than federal limits.
The state requires “do not drink” notices when PFAS levels exceed 70 ppt and mandates quarterly monitoring for systems above the 20 ppt limit. Rhode Island also passed comprehensive legislation in 2022 and 2024 banning PFAS in food packaging, firefighting foam, cosmetics, cookware, and other consumer products to prevent future contamination. This proactive approach makes Rhode Island a national leader in PFAS protection, addressing both current contamination and future prevention.
