For this study. 42samples of excreta. 42 samples of soil and 26samples of vegetables were drawn out of the conventional privys while 26samples of excreta. 26samples of soil and 26samples of vegetables out of the three septic tank privys from five villages in Chun Song County. Kang Won Province for the period from 22th August to 13th October, 1984. The major findings are as follows 1. Posi tive cases of helminthes are f ound 41 out of 42 (97.6 %) excreta of the conventional privys whereas those from the three septic tank privys are found 2 out of 26(7.7 %). Average numbers of helminthes from the excreta 0 1 the conventional privys are 4.4 whereas those from the three septic tank privys are 1.1 2. Positive cases of helminthes are found 33 out of 42 (78.6%) soil of the conventionaJ privys whereas those from the three septic tank privys are found 20 out of 26 (76.9.%). However, this difference does not reveal statistical significance (P >O.O l). Average numbers of helminthes from the soil of the conventional privys are 2.~1 whereas those from the three septic tank privys are 1.7 and the difference in total number of helminthes reveals statistical significance (P <0.05). 3. Positive cases of helmin~hes from vegetable samples drawn out of the conventional privys are founcl 13 out of 2fì (50.096) whereas tbose from the three septic tank privvs arc tOllnd 1 () out of 26 (:38.5 06).
