Nine of the beaches were located near a known source of treated sewage discharge (referred to as “point source”–affected beaches), and the remaining 4 beaches had more diffuse contamination from urban runoff (details are available in Appendix A, available as a supplement to the online version of this article at http://www.ajph.org).
