OPTIMAL WATER STORAGE STUDY OF MULTIFUNCTIONAL WATER-COMMODE CONTAINERS

Abstract

Data are presented on potability of a single source tap water stored in fiber drums lined with polyethylene, laminated polyethylene-cello phane and polyvinyl films, and on comparative storability in these liner materials of tap waters from 10 different geographical areas. Total storage period for both cases was 300 days with intra-period inspections. Storage conditions were 45 to 99 F, 20 to 90% relative humidity, indoors and dry. While all waters were considered potable under emergency conditions, by taste panel tests and chemical and bacteriological analyses, those stored in the laminated and vinyl films had a disagreeable tasts. Only 4 mil polyethylene is considered an acceptable liner for this extended period. No significant differences were found in the comparison tests of the 10 different source waters, with the exception of those from Chicago and Houston. Fiber drums and 4 mil polyethylene liners are considered satisfactory for storage of potable tap water under the conditions used. Storage cost data are presented.
