An Environmental and santiary survey was carried out on 585 houses and 36 wells in Gunseo Area, Okcheon-Gun, Choongbook Province.
As a survey on sanitary environments of houses, number of rooms they were using, artificial lightening method, house heating method and sanitary measures in the kitchen were checked.
Sanitary environments of drinking water sources were also investigated.
Other tested items with water samples were hardness, pH, and chloride ion, and the results were summarized as follows:
1. 38.1 % of all subjected households were using 2 rooms and 29.4%, 3 rooms.
97.0% of all households were lightening their houses with oil lantern and those who were using elec
