JEFFERSON CITY, MO, JUNE 29, 2010 – The Missouri Department of Natural Resources is investigating the environmental impact of a broken sewer line in Grandview that released untreated sewage into an unnamed tributary that leads to Longview Lake.

City officials reported today that a sewer line located at 6906 125th Street in Grandview had developed a break that resulted in a release of an unknown quantity of untreated sewage.  The release occurred Tuesday and lasted from 9 a.m. to approximately 2 p.m. Staff from the department’s Kansas City Regional Office were dispatched to the site to collect water quality samples and determine the extent of the environmental damage caused by the release. The Jackson County Parks and Recreation will post signs at the swimming beach and both boat ramps on Longview Lake warning visitors of the potential contamination.

Clean water regulations require the city to submit a report detailing the release to the department within five days. The department will base future enforcement action on the city’s report and the results of its on-scene investigation.

The department considers discharges of wastewater from sanitary sewer collection systems to be potential threats to public health and the environment. Such discharges have the potential to contaminate lakes and streams, causing serious water quality problems.

Sanitary sewer overflows can be caused by mechanical failure; obstructions in sewer lines; infiltration of rainwater and snow melt into aging systems; or undersized systems that cannot compensate for sudden increases in wastewater.

Communities across Missouri produce millions of gallons of wastewater that must be properly transported and treated before being released to waterways. However, some communities are facing challenges in accomplishing this.

In order to protect public health and the environment, the department requires communities to take appropriate action to eliminate their sanitary sewer overflow issues. To do this, communities should develop a system to track information about such incidents, including the date, time, location and size of the overflow, weather data, who notified them, when they notified the department and the measures taken to respond. The community can then use this data to aid in developing a plan to inspect the collection system, and plan and finance system upgrades.
