Surfers at beaches where stormwater drainage pipes discharge into the ocean risk catching more than waves on a rainy day.

Monmouth University researchers studying the influence of weather and ocean conditions on microbial pollution found that within six to 24 hours of moderate rainfall, enterococcus bacteria levels exceeded state health safety standards about half the time at these beaches. While rain is a known driver of illness-causing microbial pollution at New Jersey beaches, this was the first peer-reviewed study to formally investigate the linkage.
