Conclusions
Our Mission: To protect and improve the health and environment of all Kansans.
• Central Park Pond as a pilot test system• Small, shallow, electricity, HAB advisories• Indications were that this would work
• Unit appeared to function at some level• Deteriorating cells• Occasional low counts (natural?)
• Did not maintain acceptable conditions• Microcystis species change• Remained in Warning for majority of summer
• Other problems• Persistent DO sags• Nitrogen and Carbon release
• Would not recommend to a friend
