Utilities that use the lime‐soda ash process to soften water frequently receive bulk shipments of granular lime in the form of calcium oxide (CaO) in large rail cars. Not all of the lime product received is usable calcium oxide. To determine the percentage of available CaO in the product, core samples should be taken from at least eight different locations in the rail car in accordance with AWWA Standard B202‐77. This month's Gimmicks and Gadgets describes a core sampling device which provides an effective and inexpensive means of taking lime samples from rail cars. Materials needed and construction specifications are discussed.
