Hudson RiverKeeper

What Hudson RiverKeeper does

Riverkeeper, doing business as Hudson RiverKeeper, is a 501(c)(3) nonprofit environmental advocacy organization headquartered in Ossining, New York, and operating continuously since its founding in 1966. Its functional mission is the protection of the Hudson River and the safeguarding of drinking water supplies for New York State residents. The organization serves two distinct constituencies: a donor and member base that funds its operations, and a public beneficiary population consisting of New York residents reliant on Hudson River-adjacent water resources.

The organization's core operational assets are its water quality monitoring program and the Water Quality Portal, an interactive map-based platform hosted at data.riverkeeper.org that publishes testing and analysis data on river conditions. Field operations include patrol and debris-removal activities covering 2,400+ river miles annually, with 404 tons of debris removed since 2012. The advocacy arm pursues Clean Water Act enforcement and policy campaigns, a posture credited with securing $5.5 billion in clean water funding allocations since 2017 and mobilizing 28,148 constituent letters to lawmakers in a single year. The organization also operates within the Waterkeeper Alliance, a global environmental movement.

The business model is donor-funded rather than transactional. Revenue is sourced from individual donations, membership contributions, and grants. The organization is recognized with the Candid Seal 2025, a third-party transparency and accountability designation for U.S. charities. Headcount is reported in the 11-50 range. As a tax-exempt 501(c)(3), the organization reinvests surplus into mission delivery rather than distributing profits.

Direct peers

• American Rivers: National nonprofit dedicated to protecting and restoring U.S. rivers — closest national-scale direct peer to Riverkeeper in mission, advocacy approach, and focus on riverine ecosystems.
• Earthjustice: Nonprofit environmental law organization that litigates against polluters and defends clean water protections — overlaps directly with Riverkeeper's legal-action track record against Hudson polluters.
• Clean Water Action: National grassroots organization focused on clean water advocacy, drinking water protection, and pollution prevention — a direct peer in mission, donor base, and policy advocacy style.
• Waterkeeper Alliance: Global network of which Riverkeeper is a member organization; provides shared advocacy frameworks, resources, and visibility across water protection organizations worldwide — a direct peer in mission and operating model.
• Chesapeake Bay Foundation: Regional watershed advocacy nonprofit protecting the Chesapeake Bay — directly comparable to Riverkeeper in mission, volunteer-driven science + advocacy + legal model, and geographic concentration around a single major U.S. waterway.

Regional players

• Heal the Bay: California-based nonprofit focused on Santa Monica Bay water quality through science, advocacy, and community engagement — a regional water advocacy peer with comparable operating model but different geographic focus.

Broad incumbents

• Sierra Club: One of the largest U.S. environmental nonprofits with a water protection and advocacy program that competes with Riverkeeper for both members and policy influence on watershed and drinking water issues.
• Environmental Defense Fund (EDF): Major national environmental organization using science, economics, and law to address water, climate, and ecosystem issues. Overlaps with Riverkeeper on water quality advocacy and donor pool, but at a significantly larger scale and broader mandate.
