In November 2025, Monroe County reported alarming findings that underscore an urgent public health crisis affecting Rochester's youngest residents. According to expanded testing data, 299 children in Monroe County had elevated blood lead levels of 5 micrograms per deciliter or higher in 2024—a significant increase from 241 cases in 2023. This represents a 24% increase in confirmed lead poisoning cases in just one year, driven partly by expanded testing initiatives but also reflecting the persistent lead contamination in Rochester's aging water infrastructure.
The county conducted 13,582 lead tests on children in 2024, a 6% increase from 2023 testing levels (Spectrum Local News, Rochester First, WHEC). These numbers paint a sobering picture: nearly 2.2% of tested children are showing elevated lead exposure, a rate that health officials and construction experts recognize as a direct consequence of Rochester's aging water system, much of which still relies on lead service lines installed decades ago.
Lead contamination in drinking water represents one of the most significant public health threats in Rochester today. Unlike many environmental hazards, lead exposure has no safe level—particularly for children under six years old, pregnant women, and nursing mothers. Exposure to elevated lead levels during critical developmental periods can cause irreversible harm, including:
The 299 Rochester children identified with elevated blood lead levels in 2024 represent not just statistics—they represent real families facing documented health risks from preventable environmental contamination. For many of these children, the primary source of lead exposure is their home's drinking water, delivered through lead service lines that connect city water mains to residential properties.
Recognizing the severity of this crisis, the City of Rochester has launched an unprecedented construction and infrastructure program to address lead contamination at its source. The Lead Service Line Replacement Program, officially confirmed as a national leader by the city itself, represents a multi-year, multi-million-dollar commitment to eliminate lead from Rochester's water system.
The city has identified multiple active replacement projects across all four quadrants of Rochester:
Current Active Projects (November 2025):
In total, the City of Rochester is replacing hundreds of lead service lines and will continue work year-round, weather permitting, with peak construction activity during traditional construction seasons. The construction scope is substantial: replacing existing lead, lead-lined, and galvanized water service tubing from the water main to each property's curb shut-off valve with new polyethylene water service tubing.
The city has established an ambitious but realistic timeline: complete replacement of all remaining lead service lines by 2030, contingent on continued State and Federal funding support. This represents approximately five years of continuous construction activity across multiple neighborhoods and districts.
The economic implications for Rochester's construction industry are substantial. Lead service line replacement requires specialized contractors, equipment, water main expertise, and coordination with residential property owners. The projects are funded through:
For construction contractors, this represents a multi-year revenue opportunity. Lead service line replacement projects require water system expertise, property coordination, specialized equipment for trench work, and restoration services—creating demand across multiple construction disciplines and subcontractor categories.
If you own residential or commercial property in Rochester, lead service line replacement will likely affect your neighborhood and property within the next five years. The construction projects follow a street-by-street, district-by-district approach, with properties selected based on confirmation of lead service line presence.
Property owners can expect:
For contractors, the program represents significant commercial opportunity. Bids and subcontracting work are typically announced through the City of Rochester's Department of Environmental Services (DES). Current scheduling information and project maps are available through the city's public portal.
According to city officials, Rochester has established itself as a national leader in lead testing and lead service line replacement initiatives. This distinction carries both credibility and responsibility: as the construction industry continues to face lead contamination challenges in aging infrastructure cities across America, Rochester's approach provides a scalable model for other municipalities.
The correlation between the 299 children identified with elevated blood lead levels and Rochester's aggressive construction response demonstrates a critical principle: infrastructure construction isn't just about buildings and roads—it's about public health and the future of an entire generation.
If you live or work in Rochester, stay informed about lead service line replacement projects in your neighborhood. The City of Rochester provides detailed project maps, street-by-street schedules, and public meeting information through its Environmental Services Department. Contact the project management team at 585-428-7049 for specific information about your property or neighborhood.
For construction professionals, monitor Rochester's Department of Environmental Services for bid opportunities and subcontractor requests. The five-year timeline ensures sustained demand for qualified contractors capable of managing water infrastructure work, coordination with municipal systems, and property restoration.
The 299 Rochester children with elevated blood lead levels in 2024 represent a public health crisis that construction and infrastructure solutions can prevent from worsening. Through systematic lead service line replacement and continued testing, Rochester is demonstrating that environmental hazards can be addressed through sustained, professional construction effort and evidence-based public health investment.
