Emerald Keepers seeks to raise awareness about water and air quality in Coronado. Data is provided by California Water Boards and Purple Air. The County of San Diego tests our waters and Emerald Keepers has air quality monitors on homes around Coronado. While we don’t know why our air quality is often worse than cities across the bridge, by publishing this information each week, we may begin to understand potential causes.
Emerald Keepers is a 501(c)(3) corporation. All donations are tax deductible.
