Mr. Mike Inform Page 2 of 3 The contents of the septic system were pumped into a 1,200-gallon tank for storage on site. The septic tank was triple rinsed and pressure washed. All wash water was transferred to the storage tank. Ground Zero collected a water sample from the storage tank on October 21, 2004. Appropriate containers were delivered under chain of custody protocol to Argon Laboratories in Ceres, California and Alturas Analytics, Inc. of Moscow, Idaho. Samples submitted to Argon were analyzed for total petroleum hydrocarbons as gasoline (TPHg) using EPA Method 8015B, benzene, toluene, ethylbenzene, and xylenes (BTEX) using EPA 802113, and volitile organic compounds (VOCs), expanded to include acetone, by EPA 8260. Samples submitted to Alturas were analyzed for methamphetamines by HPLC/MS/MS, total phosphorus by SM 4500 PF, iodide and chloride by EPA 300.0, and pH by EPA 150.1. The wastewater sample contained elevated levels of VOCs, inicuding TPHg at 2,800 micrograms per liter(µg/L), benzene at 6.3 µg/L, and chloroform at 230 µg/L,all of which are above drinking water standards. Methamphetamine was detected at 0.26 micrograms per milliliter (µg/ml), although no drinking water standard has been developed for methamphetamine. Analytical results are summarized in Table 1. A copy of the laboratory reports are included in Attachment A. Proposed Scope of Work In order to determine if contaminants are present in the soil at levels that might pose a health threat or risk to groundwater, Ground Zero propose to collect six (6) soil samples pursuant to EHD's request. One soil sample will be collected two feet below the septic tank, one two feet below the distribution box, and one two feet below each end of the two septic leach lines. Each of the borings will be advanced using a hand auger, and soil samples will be collected using a drive-sampling device containing clean brass sample tubes. Samples to be analyzed will be immediately capped and preserved in an iced cooler at a temperature of approximately 4° Centigrade. Upon completion, the borings will be backfilled with native soil. A site sketch (from the septic tank permit) showing the proposed boring locations in relation to the septic system is included as Figure 2. Soil samples will be submitted to a state-certified hazardous waste testing laboratory for analysis of TPHg using EPA 801513, BTEX using EPA 802113,VOCs (including acetone) by EPA 8260B, and methamphetamines by EPA Method HPLC/MS/MS. In order to remediate the contained water waste, Ground Zero proposes to transfer the contents of the 1,200-gallon tank to a large open top container. The container will be placed in a secure location where the water can evaporate. Ground Zero will obtain authorization from the San Joaquin Valley Air Pollution Control District(APCD) prior to initiating evaporation. Ground Zero has calculated the total mass of VOCs in the wastewater to be less than 0.05 pounds, which is well below the 2 pounds per day permit requirements for uncontrolled emissions established by APCD. After all the water evaporates the resulting sludge will be analyzed. The sludge samples will be submitted to a state-certified hazardous waste testing laboratory for analysis of TPHg, BTEX, VOCs including acetone,methamphetamines, and total and fecal coliform bacteria.
