The City of San Diego, as part of its requirement for federal water pollution discharge permits, tests an outfall at Avenida del Sol weekly. On June 26, test results revealed an above-normal level of Enterococcus. Fecal coliform levels, which are seen in high numbers when the area experiences sewage flows from the Tijuana River, were minimal on the recent test results. The sample resulted in an advisory being issued by San Diego County. The City believes that the elevated bacteria levels are from kelp breaking up near Avenida del Sol and the Coronado Shores area due to higher water temperatures, an annual occurrence this time of year. There is no indication that the bacteria are from the Tijuana River since no beaches closer to the border have tested for similar levels of bacteria. The City of San Diego tested again on June 28, June 29, July 1, and July 3. The City tested on July 5. Results should be in late July 6. The county's Department of Environmental Health conducted a test on July 2 after hearing community interest for the upcoming holiday and due to the current advisory. The test results over the last few days have shown a decline in Enterococcus levels. However, the advisory may only be lifted after a positive water quality trend that demonstrates levels have returned to below the state standard. The advisory will remain in place through the July 7-8 weekend as more samples are collected and tested. It is important to note that this is an advisory and not a closure. The advisory suggests avoiding water contact in the area. Those with a compromised immune system, or the very aged or young may want to avoid contact with the water. The City of Coronado, via Laroc Environmental, will sample the Central Beach area on Tuesday, July 3, no later than 8:30 am. Although the test will not be definitive, if we have a problem we will know quickly. We will inform the community and update this post. The City of Coronado participates in water quality monitoring programs locally and as part of regional, collaborative efforts to improve water quality for the San Diego Bay Watershed and San Diego Bay. The programs include monitoring in the receiving waters (e.g., bay, beaches) and storm drain outfalls to these receiving waters. In addition, water quality monitoring is also conducted by the County of San Diego Department of Environmental Health, the City of San Diego, and the San Diego Bay Watershed Copermittees.
