Data Used to Assess Water Quality: |
Water Board staff assessed Water Quality Monitoring Program data for Mountain Home Creek to determine beneficial use support and the results are as follows: 1 of the 6 samples exceeded the Statistical Threshold Value (STV) water quality threshold for E. coli. The STV is based on a 10% exceedance rate that is calculated monthly. |

Data Used to Assess Water Quality: |
0 of the 1 samples collected by SWAMP RWB8 Monitoring for Mountain Home Creek exhibited toxicity. A sample may have multiple toxicity test results, but will only be counted once. A sample is defined as being collected on the same day and the same location. The following organisms and parameters were utilized for the toxicity tests: Ceriodaphnia dubia for Young/female, Ceriodaphnia dubia for Survival. |

Objective/Criterion Reference: |
Water Quality Control Plan, Santa Ana River Basin |
|
Evaluation Guideline: |
The sample is toxic when the response of the organisms exposed to the sample is significantly different (worse) than the response of the organisms exposed to the laboratory control based on statistical hypothesis testing. An exceedance is counted when the significant effect code is “Significant; Less Similarity,” which means that the sample result is significantly different than the control result, and the percent effect is greater than the evaluation threshold. The default evaluation threshold is 20% unless otherwise stated. |

Toxicity is defined as a statistically significant effect in the sample exposure compared to the control using EPA-recommended hypothesis testing. The t-test is used to determine if there is a statistically significant decrease in organism response in the sample as compared to the control. |
