Data and Information Type: | PHYSICAL/CHEMICAL MONITORING |
Data Used to Asses Water Quality: | Fish were sampled for tissue analysis at one location from Mile Long Pond. A total of 3 out of 12 samples exceeded the USEPA fish tissue criterion for human health. The average wet weight mercury concentration in fish tissue was 0.17 ppm for all 12 samples collected. The number of fish collected per sample, the measured mercury concentrations in fish tissue, and the number of exceedances are, by species: Brown Bullhead- 1 sample, 0.04 ppm, no exceedances; Carp- 1 sample, 0.32 ppm, 1 exceedance; Largemouth Bass- 5 samples, 0.18-0.31 ppm (average 0.24 ppm), 2 exceedances; Sunfish Hybrid- 5 samples, 0.06-0.17 ppm (average 0.09 ppm), no exceedances. All 12 samples were collected from fish with total lengths greater than 150 mm, which represent fish most commonly caught and consumed by sport fishers and their families. |

Water Quality Objective/Criterion: | All waters shall be maintained free of toxic substances in concentrations that produce detrimental physiological responses in human, plant, animal, or aquatic life. The objective applies regardless of whether the toxicity is caused by a single substance or the interactive effect of multiple substances. |

Evaluation Guideline: | The USEPA Fish Tissue Residue Criterion for methylmercury in fish is 0.3 mg/kg (0.3 ppm) for the protection of human health. This is the concentration in fish tissue that should not be exceeded based on a total fish and shellfish consumption-weighted rate of 0.0175 kg fish/day. (USEPA, 2001) |

Temporal Representation: | Fish samples were collected during two sampling events on 6/10/2003 and 8/1/2003. |
Environmental Conditions: | Significant gold mining activity occurred during the Gold Rush era at areas nearby and upstream of Mile Long Pond (USGS, 2005). |
QAPP Information: | Data quality: Good.. Quality control for sample collection, preparation, handling, and analyses were conducted in accordance with the Surface Water Ambient Monitoring Program Quality Assurance Program Plan (Puckett, 2002) with the following exception: instead of wrapping fish in Teflon sheets before being frozen and transported to the laboratory, the fish were wrapped in aluminum foil (dull side to skin). This wrapping method should not have affected mercury concentrations. Quality control procedures for selection of target fish species and compositing of samples followed the General Protocol for Sport Fish Sampling and Analysis developed by OEHHA (Gassel and Brodberg, 2005). |
