LAUREL, Md. (WUSA9) --- WSSC crews are dealingwith 40 broken water mains in Montgomery and Prince George's counties.

According to officials, other crews are on patrol for leaks, spreading sand to help minimize icing. Once the larger breaks are fixed the leaks will be repaired, say officials.

Inspectors have confirmedeight new breaks put them on a list to be repaired.
