When San Diego city officials first brainstormed ways to clean up the bird guano at La Jolla Cove, they envisioned processes involving vacuuming or picking up the mess.
A Northern California business presented them with a different option: using bacteria that would eat up the bird poop naturally.
Blue Eagle Products makes liquids containing microorganisms that metabolize all kinds of pollutants, from grease trapped in the CIA’s kitchen (yes, really) to oil spills.
Their method could help the city of San Diego avoid a big obstacle to eliminating the guano and its stench: government regulations say cleaning discharge can’t flow into the ocean below the cliffs. Blue Eagle’s cleanup solution involves spraying the microbes in liquid form onto the rocks, which will dissolve the guano with theoretically no runoff. The company just has to be sure none of that liquid drips into the waters below.
