Behind the bolted steel doors of an old brick warehouse, Big Wes meets a nutrient company scientist to see if he can increase his crop yield. Rows of hydroponic marijuana plants soak up solution flowing through plastic troughs and light blazing from high-pressure sodium lamps.

At 50 years old, he harvests a crop of dozens of plants every week from five rented warehouses scattered along the rutted streets and alleys around the docks of Oakland.

The few dozen residents who showed up were told that the water they drank did not pose a public health risk, although officials expressed concern about the presence of one chemical in a few wells.
