Total Coliform Not to exceed a specific limit more than once within any 30-day period. limit is 23 MPN/100 mL and reported value was 79.4 MPN/100 mL at EFF-001. |
Both high total coliform sample events were preceded and followed by sample results of 1 MPN/100 mL or less. After the second event a polymer pump was noted as malfunctioning and may have been overdosing polymer. The polymer pump was immediately replaced and total coliform results are back to normal levels. |

Total Coliform Single Sample Maximum limit is 240 MPN/100 mL and reported value was 248.9 MPN/100 mL at EFF-001. |
The chlorine contact tank was offline for cleaning and maintenance the day before this sample was collected. Total coliform was < 1 MPN/100mL for 9 days prior to this sample and was also <1 MPN/100 mL for 19 days after this sample was collected. System operation was reviewed in detail and the fact that no other samples before or after the sample in question may suggest that the sample was compromised during the collection process. |

Total Coliform 7-Day Median limit is 2.2 MPN/100 mL and reported value was 3.0 MPN/100 mL at EFF-001. |
Suspected cause is higher than normal TSS loading into the treatment plant with suspected toxicity that reduced the effectiveness of the biological treatment and sand filters.
Actions taken:
1. Reviewed and maintained residual chlorine level (7.1 to 11.1 mg/L) and the CT value (842 to 1,347 mg/L-min) in recycled water at adequate levels.
2. Identified that coliform was associated with sand filtration (which was removed system from service) and only operated microfiltration (MF) treatment.
3. Thoroughly cleaned, disinfected, and flushed sand filters remove any accumulated biological growth.
4. Soaked sand filters overnight with 2,500 mg/L free chlorine solution, and then thoroughly mixed sand to ensure no foreign material remained.
5. Clean, power washed, and disinfected upstream flocculation basin, channels, and wetwell.
6. Increased coliform sampling to 2-3 times per day to verify effectiveness of cleaning efforts.

Deficient Reporting |
Visual observations of the surface water conditions are required whenever a surf zone sample is collected. Surf zone sampling occurred on September 9, 2020 but one of the staff lost/misplaced the Visual Observation Form for that day. |
In response to the Visual Observations Form that was misplaced after the September 9, 2020 shoreline sampling event, the San Elijo Joint Powers Authority (SEJPA) has investigated the incident and instituted corrective actions to make sure this does not happen again. Chris Trees states that in the 11 years that he has been Director of Operations, and the 20 years that Mike Thornton has been the General Manager, this is the first time that one of these forms has been misplaced; thus, SEJPA has properly collected and filed this information over 1,000 times without incident.
A Corrective Action Report was initiated and the investigation recommends that an electronic copy of the form (photo) is created in the field as soon as the last sample is logged and this electronic copy will be texted or emailed to the Laboratory Manager prior to returning to the laboratory. When the staff responsible for sampling has returned to the office, the original hard copy will be brought in with the samples and submitted to the Laboratory Manager for review. Once the hard copy is reviewed and signed in the office, the hard copy will be scanned and saved electronically on the SEJPA computer network. The original copy with signatures will be filed in the laboratory binder and retained in accordance with the document retention policy. |

*As of 5/20/2010, the Water Board's Enforcement Policy requires that all violations be classified as 1, 2 or 3, with class 1 being the highest. Prior to this, violations were simply classified as Yes or No. If a 123 classification has been assigned to a violation that occurred before this date, that classification data will be displayed instead of the Yes/No data.
