Sewage treatment plant. I wonder if anyone has checked to see if these are leaking into the lake?

Saw the equipment this weekend......... Hopefully this helps.....

Comment on the sewage ponds, they where included in a report I read on the situation, so I am sure any possible source is being studied....

Bill Gassman has a really great drone video of Phase 1 last week, and here is the FAQ doc for anyone wanting to know more about the treatment.

In regards to the lagoons...

From the Lake K Watershed Management Plan "The land use based watershed load alone (assuming no point source discharge to groundwater from the lagoons) generated a predicted annual in-stream total phosphorus concentration matching observed data well. Given the lack of discrepancy between predicted and observed total phosphorus concentration, there is currently no evidence that the sewage lagoons pose a significant threat to the water quality of Lake Kanasatka. Despite no concrete evidence of potential groundwater contamination from the lagoons, NHDES has encouraged the Bay District Sewer Commission to pursue funding for a planning study to “assess the feasibility for discontinuing the use of its unlined lagoons and instead discharge all of its wastewater directly to the WRBP wastewater treatment facility, as well as permanent closure of the lagoons” (NHDES, 2022e).

It would probably be less expensive in the long run to line the lagoons.
