In Memory of Joan Jessen

Joan R. Jessen, one of the founders of the Washington County Watershed Alliance and Chartiers Creek Watershed Association, passed away at the age of 96, Monday, December 21, 2020.

Joan described herself as a professional volunteer. Her volunteer career began after she graduated from Mary Washington College in Virginia with a BS in Chemistry with minors in English and History, worked as a chemist, married the late Myron “Jess” Jessen, and saw their three children off to school in Peters Township.

We remember her as a talented and tireless volunteer for the environment, which was just one of her many volunteer activities. She co-founded the Washington County Groundwater Coalition and later the Washington County Watershed Alliance and Chartiers Creek Watershed Association. Over more than 20 years, she served as President, Secretary, and Treasurer of the Board of the Alliance and President, Secretary and Treasurer of the Watershed Association. She volunteered as a stream monitor, wrote grant applications, news releases, newsletters and annual reports, and represented both groups at events like the County Fair. In 2012, she received the Jefferson Award for Public Service.
We greatly appreciate Joan’s contributions and extend sincere condolences to her family.

In her memory, the Washington County Watershed Alliance is collecting donations which will be contributed to the Peters Township Tree Fund Program. Peters Township matches every donation made to this fund. Monies will be used to purchase trees for planting throughout Peters Township parks and public lands. If our contribution is $100 or more, it will be acknowledged on a Tree Donation Plaque permanently displayed in the Municipal Building.
