Odd Odor In Storm Lake

Storm Lake, IA (KICD)–An unusual odor has Storm Lake officials stumped.

Storm Lake Public Safety personnel were initially called out shortly after noon on Wednesday to the areas of the 100 and 200 blocks of Irving and Cayuga Street in reference to a strong odor of natural gas. The odor was coming from the sanitary system manholes at several locations in the area.

Alliant Energy, Veolia Water, Iowa DNR and the Storm Lake Street Department all responded to the scene and testing done at the scene determined the odor was not caused by natural gas. Samples were taken in the manholes at several locations and no signs of any petroleum products in the waste water were evident.

Throughout the afternoon Public Safety received reports of the odor in the area that extended as far east as Taylor Construction located at 307 Flindt Drive.

City crews used ventilation fans to extract the unusual odor from the system at the intersection of Irving and East 1st Street. In addition Late Wednesday afternoon City crews flushed the system with approximately 3000 gallons of water.
The manholes were monitored throughout the night and the sanitary System is being checked today by city crews and the DNR.

While there is no apparent danger to homes. Citizens living in the area are encouraged to check their basement floor drains to ensure there is sufficient water in the drain traps to keep sewer vapors from entering their homes.

Crews were on scene collectively for approximately three hours.
