Olympian Water Testing™

Jefferson Township, located in Morris County and established in 1804, historically relied on private wells and natural springs drawing from the region’s rich groundwater resources in the Highlands watershed area. The township’s development pattern as a rural and later suburban community meant that residents primarily depended on individual water sources throughout much of its history, with Jefferson Township’s historical records noting the importance of Lake Hopatcong and other water bodies to the area’s development, particularly during its period as a resort destination in the late 19th and early 20th centuries.

Today, Jefferson Township’s water supply is managed through a combination of systems, with many residents still using private wells while others are served by small community water systems or the township’s public water utility. According to the New Jersey Department of Environmental Protection, Jefferson Township Water Utility serves portions of the township, while other areas receive water from the SUEZ Water New Jersey system. The township’s location in the environmentally sensitive New Jersey Highlands region, which provides water to over 5 million state residents, has led to special protections under the New Jersey Highlands Water Protection and Planning Act, recognizing the area’s critical importance to the state’s water resources.

Like many communities in northern New Jersey, Jefferson Township faces water management challenges including protecting water quality in an area with significant natural resources, maintaining aging infrastructure, and balancing development pressures with water resource conservation. The township’s Utility Department conducts regular water quality testing and publishes annual Consumer Confidence Reports to ensure compliance with state and federal standards. As climate change impacts intensify and development continues, Jefferson Township’s approach to water management increasingly focuses on watershed protection, sustainable water use practices, and infrastructure improvements to ensure reliable water supplies while preserving the natural environment that has historically defined this Highlands community.
