A percolation test Is a est me o to <br /> dete e the suitability of the soils. Please see the next section for percolation test results. <br /> LGenerally speaking, sandy soils have much greater potential for percolation than fine-grained or <br /> clayey soils. <br /> L <br /> 8 <br /> L '004 <br /> L <br />
