Water Quality Index Score: 72, Fair
To no surprise, our 2014 data showed that:
- Nitrate is consistently high in upper Escondido Creek
In fact, four of the five samples with the highest nitrate concentrations collected anywhere in San Diego County this year came from Escondido Creek. Because of this, our volunteers report seeing a lot of algae growth in the water.
We’re not surprised because nitrate always measures high in Escondido Creek, but we’re interested in learning why this consistently happens. Recently, we inquired with the City of Escondido, and representatives say it comes from groundwater and the legacy pollution from the agriculture industry. Thankfully, our longtime volunteer and new board member, Taya Lazootin, is running a research project examining nitrate in Escondido Creek to figure out what’s happening. We’re hoping her final report has more insights into this problem.
