MERCER UNIVERSITY CENTER (COLD POOL)

Observed low PH levels. (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 contact the pool company to balance the water chemistry.

Observed high total and combined chlorine levels. (1) Disinfectant Levels (a) Free chlorine, ppm in pools not using cyanuric acid or a stabilized chlorine compound use (b),1.-5. PIC is to inform the pool company of the need to balance the water chemistry.

Observed flow meter not working; unable to obtain reading as the it has exceeded the numerical margins. (b) A flow meter measuring the rate of flow through the filter system with an appropriate range readable in gallons per minute (GPM) and accurate within ten percent actual flow shall be provided. The flow indicator shall be capable of measuring from one-half to at least one and one-half times the design flow rate. The gauge shall be located after the filtering equipment and in such location on the return line, so as to measure the total amount of water returning to the pool according to the manufacturer’s installation specifications. Facility is to install an appropriate flow meter.

Observed no daily logs on-site. (9) Water Testing Frequency. The trained operator or responsible person shall collect water samples from the water in the pool for monitoring. An in-line sampling port may be used for water held in reservoirs. PIC is to speak with the pool company about leaving daily logs.

Observed low alkalinity and calcium hardness levels. PIC is to inform the pool company of the need to balance the water chemistry.

Observed low PH levels. (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. EHS informed CPO, who conducted tests himself and received the smae results; will make the neccessary adjustments.

Observed high combined chlorine levels. (1) Disinfectant Levels (a) Free chlorine, ppm in pools not using cyanuric acid or a stabilized chlorine compound use (b),1.-5. EHS informed CPO will make the neccessary adjustments.

Obseved low alkalinity and calcium hardness levels. EHS informed CPO, who had just conducted tests himself and achieved the same results; will make the neccessary adjustments.

Observed combined chlorine levels being slightly high. (1) Disinfectant Levels (a) Free chlorine, ppm in pools not using cyanuric acid or a stabilized chlorine compound use (b),1.-5.EHS informed the PIC who contacted the CPO.

Observed flow meter not working; unable to obtain reading as the it has exceeded the numerical margins. (b) A flow meter measuring the rate of flow through the filter system with an appropriate range readable in gallons per minute (GPM) and accurate within ten percent actual flow shall be provided. The flow indicator shall be capable of measuring from one-half to at least one and one-half times the design flow rate. The gauge shall be located after the filtering equipment and in such location on the return line, so as to measure the total amount of water returning to the pool according to the manufacturer’s installation specifications. Facility is to install an appropriate flow meter.

Observed high alkalinity levels(unable to obtain reading) and low calcium hardness level. EHS informed PIC who contacted the CPO.

Observed chlorine level that were too high; unable to obtain a reading. a) During operation, disinfectant levels are less than the minimum level specified in DPH Rule 511-3-5-.17. If the level of the disinfectant used is not specified in DPH Rule 511-3-5-.17, the disinfectant must be approved and kept at levels determined necessary by the health authority. EHS informed the PIC who contacted the CPO. Per CPO, he will come by again to address the issue.

Observed combined chlorine levels being high as a byproduct of high free chlorine levels. (1) Disinfectant Levels (a) Free chlorine, ppm in pools not using cyanuric acid or a stabilized chlorine compound use (b),1.-5.EHS informed the PIC who contacted the CPO; Per CPO, he will come by to address the issue.

Observed flow meter not working; unable to obtain reading as the it has exceeded the numerical margins. (b) A flow meter measuring the rate of flow through the filter system with an appropriate range readable in gallons per minute (GPM) and accurate within ten percent actual flow shall be provided.

Facility is to install an appropriate flow meter.

Observed high alkalinity levels(unable to obtain reading) and low calcium hardness level. EHS informed PIC who contacted the CPO; per CPO, he had added acid to the pool this morning and he will come back by to address the issue.
