(REV 5-2040) (FA 6-940) ( 141 ) SECTION 923 (Pages 848 - 849) is deleted and the following substituted : SECTION 923 WATER FOR CONCRETE 9234 General Requirements . Water for use with cement shall be clear and free from oil , and injurious amounts of acid, alkali , chlorides , organic matter, and other deleterious substances . It shall not be salty or brackish . If it contains quantities of substances which discolor it or make it smell or taste unusual or objectionable or cause suspicion, it shall not be used unless approved by the Department . LL Water sources permitted include potable water supplies that are approved by a public health department, open bodies of water, well water, reclaimed water, and recycled water. Reclaimed water shall be as defined in Chapter 62 - 610 , F . A . C . Open bodies of water are defined as naturally occurring rivers , lakes , and ponds . Recycled water includes wash water from mixer washout operations (stored in a lined settling pond) . All other sources of water not listed above shall be considered recycled and reclaimed water . Recycled and reclaimed may be used only to sprinkle the coarse aggregate stockpiles and for batching concrete meeting the requirements of Section 347 , 923 -2 Evaluation of Water for Concrete. 923-2 . 1 General : Water from potable water supplies approved by a public health department may be used without additional testing. The concrete producer shall provide test data of water samples from other sources . To determine chemical properties , use a laboratory accredited by the National Environmental Laboratory or Construction Materials Engineering Council Accreditation Program . To determine physical properties , use a laboratory accredited by the Construction Materials Engineering Council Accreditation Program or Cement and Concrete Reference Laboratory, 923 -2 . 2 Initial Sampling and Testing Frequency : Open bodies of water and well water shall be initially sampled once prior to use . Recycled and reclaimed water shall be tested once per week for four weeks initially, and thereafter once per month for four months prior to its use , provided that the results of the test samples comply with all the applicable limits . Failing test results will result in restarting initial sampling and testing . 923 -2 .3 Production Sampling and Testing Frequency : Open bodies of water and recycled water shall be tested monthly. Well water and reclaimed water shall be tested once every three months . If the last eight consecutive well water and reclaimed water samples meet the requirements , then the sample frequency may be reduced to one sample every six months , as approved by the Department . If a well water or reclaimed water sample fails once the frequency has been reduced, then the sampling frequency shall revert back to once every three months . 923 -3 Chemical Requirements . 923 -3 . 1 Testing : All chemical analysis or tests shall be performed in accordance with the test methods listed in Tables 1 and 2 or Standard Methods for the Examination of Water and Wastewater. - 210 - FPID ( S ) : 423186 - 1 - 58 - 01 71, x
