Tests Confirm Rainfall Affects Bacteria in Kansas City Streams

After 40 years EPA finally figured out rainfall washes bacteria off land into water. Twelve years ago, John Dunn,
Region 7, told me bacteria would not wash off a sludge site onto our farm. It did. See link to tests.
Of course, EPA put the laboratory owner in jail. Claimed he was under reporting bacterial levels in water tests!

Environmental News


(Kansas City, Kan., May 21, 2010) - Recent tests by EPA have shown increased levels of E. coli after recent rains in
Kansas City area streams. The tests are part of a year-long project by the Agency to better understand water quality
in the Kansas City area streams including Line, Shoal, Tomahawk, Indian, Mill, Coffee, Brush, Brenner Heights, and
Turkey creeks, as well as the Little Blue and Blue rivers.

As part of this survey, samples will be analyzed to understand the relationship between bacteria and other water
quality parameters.

Sampling conducted this past week showed levels of E. coli ranging from 100 colony forming units per 100ml in a
sample taken from Brush Creek at the Ward Parkway crossing, to 4,000 units  per 100ml from a sample taken from
Brush Creek at Rockhill Road. These numbers are consistent with past studies by the U.S. Geological Survey.

Rainfall washes bacteria into waters from sources such as runoff and combined sewers. Bacteria levels can rise
rapidly as a result of rain, and in larger urban areas, generally drop back to normal levels within 48 to 72 hours. After
a rain event, water quality is less favorable for swimming and activities around water. If you must come in contact with
untreated waters during these times, make sure you avoid situations that might cause you to swallow water, and be
sure to wash your hands before eating.

Completed results from EPA’s results of recent sampling will be available next week.
