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.
