The shallow test passed the <br /> minimum County requirements. <br /> 6.5 The test conformed to SJC Policy EH 02-02 (correct depth,diameter,2" gravel,6" water <br /> refill,correct readings recorded). The percolation test conformed to San Joaquin County Policy <br /> EHD 02-02. <br /> 6.6 Complete Percolation Test Form (including readings) was provided with REHS <br /> verification signature. The rate was correctly calculated using the last reading.
