Stations at River Crossing

Observed chlorine reading was too high that it could not give a reading.c) Free Chlorine level in pools using cyanuric acid or a stabilized chlorine product; Minimum 2.0 Ideal 2.0-5.0 Maximum 10.0. PIC is to get with CPO to balance the water chemistry.

Observed PH reading at 7.1. (2) Chemical Values: pH 7.2 7.4-7.6 7.8 Alkalinity (buffering), 60 ppm 80-100 halogens compounds with high pH 180 ppm as CaC03 100-120 halogen compounds with low pH Calcium hardness, ppm, CaCo3 150 200-400 to balance water 1000. PIC is to get with the CPO to balance the water chemistry.

Observed cyanuric acid reading was too high. (4) Stabilizer (if used) Cyanuric acid,ppm Ideal: 30-50 Maximum: 90 Comments: If stabilizer is: Too High: - May reduce chlorine efficacy Too Low: - Chlorine Residual rapidly destroyed by sunlight Note: Stabilizer is not needed in indoor or brominated pools and spas.

EHS informed PIC to contact CPO to balance the water chemistry.

Observed NO DIVING wording in 4inch letters not present on the pool deck. (a) The words "No Diving" and the universal international symbol for “NO DIVING” shall be permanently visible at the edge of the deck for water five feet in depth or less, placed only on the deck beside the depth markers, and shall conform to that outlined for depth markers in subsections (3)(a) thru (h) above. EHS informed PIC of the need to purchase the non-slip NO DIVING deck stickers in 4 in letters.
