| Contact DWP for a special monitoring schedule when positive results are found. | |||
| Radiological Monitoring - Revised | |||
| 1. Initial Monitoring Requirements | |||
| Radioactivity - Section 64442 | MCL*** | EPA Method | Frequency |
| Gross Alpha * | 15 pCi/L | 4 quarters initial monitoring | |
| Radium-226 * | 5 pCi/L | When GA > 5 pCi/L** | |
| Radium-228 * | Radium-226 & -228 | 4 quarters initial monitoring | |
| Uranium * | 20 pCi/L | When GA > 5 pCi/L** | |
| Man Made Radioactivity - Section 64443 | |||
| Tritium | 20000 pCi/L | Not Required | |
| Strontium | 8 pCi/L | Not Required | |
| Gross Beta | 50 pCi/L | Not Required | |
| * If the results from the first two quarters of initial monitoring are below the detection limit for purposes of reporting | |||
| (DLR), the final two quarters of initial monitoring may be waived. | |||
| ** If the gross alpha (GA) activity is more than 5 pCi/L, analysis for uranium may be used to obtain the radium-226 activity | |||
| (Gross alpha - Uranium = Radium-226). If Gross alpha - Uranium > 0, call the DWP for further instructions. | |||
| If Gross alpha - Uranium < 0, report only the Gross alpha and Uranium results. If the GA activity is more than 15 pCi/L, | |||
| analysis for uranium must be performed. | |||
| *** Contact the Tehachapi District Office if the MCL is exceeded. | |||
| 2. After initial monitoring outlined above has been completed, the subsequent monitoring frequency will be | |||
| based on the initial monitoring results as follows: | |||
| If Gross Alpha is | Less than 3 pCi/L | Then | Monitoring Frequency is One Sample Every Nine Years |
| * If the gross alpha activity is below 3 pCi/L, and the sample was not analyzed for radium-226 and uranium, the monitoring | |||
| frequencies for Ra-226 and U would be 1 sample every 9 years because at this level gross alpha particle activity can | |||
| be substituted for Ra-226 and U. In this case, a sample collected once every nine years and analyzed for gross alpha | |||
| activity would satisfy the radiological monitoring requirements for gross alpha, Ra-226, and U. | |||
| If Gross Alpha is | > 3 and < 7.5 pCi/L | Then | Monitoring Frequency |
| If Radium-226* is | > 1 and < 2.5 pCi/L | Then | is |
| If Radium-228 is | > 1 and < 2.5 pCi/L | Then | One Sample |
| If Uranium* is | > 1 and < 10 pCi/L | Then | Every Six Years |
| * If the gross alpha activity is between 3 and 5 pCi/L, and the sample was not analyzed for radium-226 and uranium, the | |||
| monitoring frequencies for Ra-226 and U would be 1 sample every 6 years because at this level gross alpha particle | |||
| activity can be substituted for Ra-226 and U. In this case (GA between 3 and 5 pCi/L), a sample collected once | |||
| every six years and analyzed for gross alpha activity would satisfy the radiological monitoring requirements for gross | |||
| alpha, Ra-226, and U. | |||
| If the gross alpha activity is more than 5 pCi/L, the sample must be analyzed for Ra-226 or U. | |||
| If Gross Alpha is | > 7.5 and < 15 pCi/L | Then | Monitoring Frequency |
| If Radium-226* is | > 2.5 and < 5 pCi/L | Then | is |
| If Radium-228 is | > 2.5 and < 5 pCi/L | Then | One Sample |
| If Uranium* is | > 10 and < 20 pCi/L | Then | Every Three Years |
| * Because the gross alpha activity is more than 5 pCi/L, the sample must be analyzed for radium-226 or uranium. | |||
| If the gross alpha activity is more than 15 pCi/L, the sample must be analyzed for U. | |||
| The monitoring frequencies for gross alpha, radium -226, radium-228, and uranium may be different. |
