WaterKeeper Alliance

What WaterKeeper Alliance does

WaterKeeper Alliance is a 501(c)(3) nonprofit organization founded in 1999 and headquartered in New York City that serves as the coordinating body for a global movement of 295 affiliated Waterkeeper groups protecting 6.4 million square miles of waterways across 42 countries and territories on six continents. The organization functions as a federated advocacy platform where locally embedded Waterkeeper groups patrol waterways, organize clean-ups, educate communities, and pursue legal action against polluters, with the parent alliance providing training, communications, legal resources, and fiscal sponsorship. WaterKeeper Alliance primarily serves the general public and communities impacted by water pollution, environmental advocates seeking to launch local Waterkeeper organizations, and policy-makers and regulators engaged on clean water enforcement. The core operations span three primary campaigns: Clean Water Defense, Climate and Safe Energy, and Pure Farms, Pure Waters.

The organization's products and technology center on a citizen science water monitoring platform using standardized testing protocols for PFAS contamination and plastic pellet pollution, combined with the Nurdle Patrol online database that aggregates volunteer data across countries. Supranational offerings include the waterkeeper.org website serving as the global hub for news, advocacy action alerts, and an interactive map to find local Waterkeepers; the Equity In Every Drop Podcast amplifying movement voices; the Waterkeeper Warriors video series produced with Culture Trip and narrated by Lupita Nyong'o; the Waterkeeper Magazine publication; the Dive Into Democracy advocacy action series; and the International Plastic Pellet Count annual citizen science initiative.

WaterKeeper Alliance generates revenue through a donation-based nonprofit model including individual one-time and recurring monthly contributions (with suggested amounts from $35 to $1,000), legacy giving through wills and trusts, stock donations, IRA qualified charitable distributions, donor-advised funds, and boat donations. Secondary revenue sources include fiscal sponsorship administrative services provided to eligible Waterkeeper groups and partnership coalition work with organizations including American Bird Conservancy, Oceana, Surfrider Foundation, and UN-Water. The organization processes donations through a multi-channel platform spanning direct website contributions, FreeWill for legacy giving, Benevity and Network for Good for corporate employee giving programs, and a dedicated online storefront. The organization has earned Four Star Charity Navigator, Platinum Transparency Seal from GuideStar/Candid, and Charity Watch ratings, and is supported by a 19-member Board of Directors, 24-member Board of Trustees, 20-member Waterkeeper Council, and 45-member Leadership Circle.

Core offering

Waterkeeper Alliance operates a global network of 295 community-based Waterkeeper groups across 42 countries and territories, coordinating grassroots advocacy, citizen science water monitoring, legal action against polluters, and public education to protect rivers, lakes, and coastal waterways. The organization also provides fiscal sponsorship, training, communications support, and shared data infrastructure to its affiliated local Waterkeeper groups.

Product overview

Waterkeeper Alliance operates primarily as a nonprofit advocacy organization rather than a technology product company. Its core offering is a global movement platform connecting 295 Waterkeeper groups across 42 countries through its website (waterkeeper.org), which serves as a hub for news, advocacy campaigns (Dive Into Democracy), and clean water resources. The organization supplements this with the Equity In Every Drop Podcast for storytelling, the annual International Plastic Pellet Count citizen science initiative, and the Waterkeeper Warriors video series. The website functions as the primary interface through which supporters engage with advocacy actions, find local Waterkeepers, access educational content, and support clean water campaigns.
