Alleged Bay Pollution
There is an ongoing discussion concerning this subject on a different PV BB. The following was pulled from that list:
In PV the water is Brown during the rainy season as the earth moved by the heavy rain fall goes into the rivers from the mountains.
The brown foam sometimes seen just off the breakers in the bay is caused by nutrients and crustacean molt mixing with silt which come to the surface at certain times due to upwelling water movements. This is an entirely natural phenomenon and actually shows a good, healthy environment. It is evident in many places on the eastern Pacific shores. The general manager of BiWater who runs the waste water treatment, assures that the water he puts back into the bay is cleaner than the tap water in Mexico City.
