Where the work happens

3 program services account for $1.7M of program spending, described in the organization's own filed words · FY2024.
01

Watershed Protection

We identify sources of pollution and analyze how to stop them. We regularly patrol the rivers we work to protect. We respond to tips and complaints. We review public records - like discharge monitoring reports and inspection reports to assess whether violations have occurred.

$1.4Mprogram expense

Shenandoah

We upgraded our monitoring equipment for toxic algal outbreaks so we dont have to rely on the state to determine when and where they occur. We filed multiple algae complaints with the Commonwealth to encourage the state to monitor for algal outbreaks.

03

Upper Potomac

We expanded our investigation and awareness campaign for PFAS (forever chemicals), including partnering with USGs on testing PFAS levels in fish tissue and blood and partnering with faculty at Frostburg State.

The names, titles, and compensation shown on this page are reproduced from IRS Form 990 filings, which are public records.

Philanthropy.org does not alter the content of those filings. All information appears exactly as reported by the filing organization for the tax year shown.

We publish only information contained in the public IRS filing — and less than the filing contains. Our profile pages do not display street addresses, telephone numbers, personal email addresses, or other personal contact information, even where the filing includes them.

Many people share the same name. A name shown on this page reflects only what one organization reported in one IRS filing for one tax year. It should not be interpreted as identifying any other individual with the same or a similar name.

If you are no longer affiliated with the organization, your name will generally stop appearing in future IRS filings once the organization no longer reports you. Pages for tax years in which you were reported remain published because those filings remain part of the public record.

Philanthropy.org does not alter or remove IRS filing records. Removing a page from this website would not remove the underlying IRS filing, which remains publicly available from the IRS and other publishers of the same information.

If you believe the IRS filing itself is inaccurate, corrections must be made by the filing organization or the IRS directly.
