Floor drains that back up
Storm overloads push sewer water into the lowest drain.
In Bayonne, heavy rain has a history of ending up in basements. A peninsula between two bays with a combined sewer means backups, not just leaks, drive much of the mold work here.

In Bayonne, NJ much of our mold work starts with water from below: basement sewer backups during heavy rain, storm flooding on low streets, and the mold that follows when basements are not cleaned and dried properly. We come from our Newark office, clean up to the Category 3 standard where the water was sewage, and dry with readings.
Bayonne has dealt with frequent sewer backups during rainfall because its combined sewer overflow system could not handle the volume, and the city has since added an underground retention basin at Francis G. Fitzpatrick Park to hold storm runoff. When a September 2018 rainstorm dropped several inches of rain, water got into basements across the city and nearly a dozen people had to be rescued.
That history is why we ask Bayonne callers where the water came from. A backup through a floor drain is sewage, and it changes what can be kept and how the space is cleaned.

See the jobWe start at the floor drain and the lowest point of the basement, then work outward to measure how far the water went and how high it wicked. Stored items on the floor get sorted before anything goes to the curb.
We also note whether the drain has a backwater valve, since that one fitting is often what prevents the next backup.
The combined sewer overloads and your floor drain is the lowest outlet. A plumber can advise on a backwater valve.
