This is a follow-up to a comment on a topic introduced within a previously hijacked thread...
In early March 2025, Helena and SePro initiated work with Texas Parks & Wildlife biologists on a “case study” to technically and empirically document the effects of various EutroSORB formulations on a 5 surface-acre city park pond in Katy, TX (Mary Jo Peckham Park).
The park’s pond is occupied (“infested” 😉) by a relative high population of waterfowl, which do what waterfowl do best when fed ample amounts of foodstuffs by the visiting public.
In 2023 & 2024, the park’s pond experienced several bouts of excessive planktonic algae blooms, often accompanied by Cyanobacteria blooms that posed a threat to both “wildlife” and park-visiting pets.
The objective of the case study is to document effects & benefits associated with a properly executed phosphorus mitigation program.
Lanthanum (a rare earth element) is the key component found in the various EutroSORB formulations. Use-rates for one or more formulation are more accurately based upon phosphorus sample results rather than a predesignated rate per acre or acre-foot. Accordingly, the formulation(s) and dosage(s) for this case study will be based upon collected water and benthic soil samples, which are currently undergoing analysis within SePro’s water-quality testing lab.
The final results of this case study will become available this fall after the treatment(s) have concluded and several post-treatment water/soil samples are analyzed.
Personally, I believe this case study will provide an excellent comparison to innumerable private ponds that suffer from the effects of excessive & long term eutrophication.
I’m happy to share the case study results (later this year) with anyone who expresses an interest.
UPDATE: The application was executed on Thurs/May 15th. Video linked below. Post-treatment sampling will occur at two intervals between July & October.
