Receive a CWSN T-Shirt after donation!!

For every donation of $50 or more ($25 or more for students), we want to thank you with a Clean Water Science Network t-shirt!

All donations contributed to CWSN via PayPal are processed via PayPal Charitable Giving. This automatically provides you a tax receipt and avoids processing fees, but does not give us sufficient information to get you your t-shirt. After donating, please fill out the form below.

We will ship our T-shirts to donors once per month, the first or second week of the month!

Thank you! We really appreciate your support!

Note: Feel free to send us a picture wearing our t-shirt to post on our website (

Thank you!
