Scripps Finds 27 Offshore Waste Barrels Leaking Alkaline Pollution off Southern California

Summary
27 deep-sea barrels off Southern California are leaking highly alkaline waste, with Scripps researchers saying the pollution is still actively altering the seabed decades after dumping ended.
pH readings near 12 around some barrels—versus normal seawater at 8—created white halos of brucite and a caustic seafloor where microbial life is sparse and adapted to extreme conditions.
At least a third of the examined barrels showed those halos, suggesting alkaline leakage may be widespread in the dump field between the Palos Verdes Peninsula and Santa Catalina Island.
14 offshore areas were used for waste dumping from the 1930s to the 1970s, and researchers say the long-term ecological and food-chain risks still need study in a region already tainted by DDT.
What hidden dangers lurk in the marine food chain from decades of leaking, highly caustic industrial waste off the California coast?
Could unexpected chemical halos surrounding sunken radioactive waste barrels actually be preventing a much larger ecological catastrophe in the Pacific?
How many more toxic deep-sea dumping grounds remain undiscovered, silently altering marine ecosystems long after humanity assumed they were safely diluted?
