THE KANSAS LIFELINE

July 2018

seriously considering adding such

chemicals then your supplier

needs to provide two things: 1) an

independent, third-party study

showing the effectiveness of the

product; and, 2) a list of other

cities or sewer districts that have

used their products and treatment

dramatically improved (based on

actual, verifiable data). Absent either

the study or list and data, I would not

buy any such products.

If I can ever be of assistance with the

operation of a treatment plant or

lagoon, please feel free to contact me at

either 913-850-8822 or jeff@krwa.net.

You may also contact the KRWA office

at 785-336-3760. I am also available to

discuss the use and effectiveness of any

chemical prior to purchase. Again,

make sure to carefully evaluate any

chemicals that your system plans to

purchase in order to make sure it will

be use legally and that it will

effectively control the targeted aquatic

plants causing problems.

Jeff Lamfers began work

for KRWA in November

2008. Jeff has more than

thirty years of regulatory

experience in the oversight

and operation of water and

wastewater systems with

the Kansas Department of

Health and Environment.

He is a graduate of the University of Kansas

with a degree in Environmental Studies with 

an emphasis in aquatic biology. 

This photo shows conditions typical during a seasonal turnover. Note the brownish-

green color of the wastewater and the clumps of solids floating on the surface. Such

conditions often result in offensive odors. Turnovers typically correct themselves in

a week or two. But if complaints are being received, treatment with sodium nitrate

can hasten the recovery.

I would like to make one

last comment about adding

enzymes or bio-catalysts to

sewage lagoons. They are

not needed!
