Media-specific sampling criteria are organized by the sampling medium. E-1727 is the designation used for soil sampling criteria, guiding how soil samples are collected when assessing lead hazards. This includes where to sample (areas where children play and around foundations), how deep to collect (to capture the surface soil most likely to be contacted), and how many samples to combine to obtain a representative result. The other media have different criteria codes, so referencing E-1727 points to soil rather than air, dust, or paint chips. That’s why soil sampling criteria is the correct interpretation.
