Which of these ammonia test results are from the Tijuana River?

Which of these phosphate test results are from the Tijuana River?

If you guessed the dark blue ones, you are correct! Give yourself an A. These test tubes are some of the results from last weekend’s volunteer water quality monitoring event. The ammonia, nitrate, and phosphate levels in the Tijuana River were literally off the charts high. When it rains (which it recently had), the treatment facilities get overwhelmed and raw sewage flows into the river and out to the ocean. Our water quality tests show those trends in the water quality.
Check out Jen’s blog on July’s Tijuana River Valley sewage spill to learn more about efforts underway to fix this problem. You can check out the results of our water monitoring efforts at the watershed wiki. And don’t forget to check the current beach status before you head out into the water.
The Surfrider Blue Water Task Force is a great way to get involved and take action to prevent contaminants from reaching San Diego’s watersheds and ultimately reaching the Pacific Ocean to negatively impact our coast and marine life. Blue Water Task Force members currently monitor the bacteria levels in the Tijuana River Watershed on the US side of the border, specifically at the Tijuana River mouth and other select areas in the Tijuana Estuary.
