Spill noted, reported to CNV.
High pH value - off the scale of WR chart. Estimate about 10. For comparison, tested pH and water hardness downstream; pH downstream was 8.4, alkalinity/water hardness had lower values. Relayed to CNV that concrete contaminiation suspected.
Update: Source of spill identified. Concrete overpass being taken down on 23rd St for new community centre. Concrete slurry was making its way into storm drain.
heavy rain last 2 days. catchment was salted due to freezing in past week.
some invasives coming back to the pool edge.
**did the test strips 2x and took average of the 2 tests for alk and hardness. as 1st test was read too quickly.
