The city's actions are a wake-up call that the entire nation regularly consumes foods grown on fields fertilized with sludge.
When San Francisco, one of the greenest cities in America, offered its residents free compost, many were excited to take it. After all, purchasing enough compost for even a small 10 x 10-foot garden can cost over $50, and generating one's own compost in high enough quantities for such a garden takes a long time.
Few of the gardeners who lined up to receive the free compost at events like last September's Big Blue Bucket Eco-Fair suspected that the 20 tons of free bags labeled "organic biosolids compost" actually contained sewage sludge from nine California counties. On Thursday, March 4, angry San Franciscans returned the toxic sludge to the city, dumping it at Mayor Gavin Newsom's office in protest.
