Laboratory Evaluation of the Leaching of Organics From Fabric Material

Abstract

Samples of fabrics made for collapsible potable water storage tanks by five manufacturers were used to evaluate leaching of organics under three test conditions: control medium (pH = 8.3) at 20°C; low‐pH medium (pH = 5.8, Cl2 = 10 mg/L); and control medium at 50°C. The extraction procedures were basically those described in National Sanitation Foundation standard 61. Results indicated the presence of trace amounts of organic compounds, but the concentrations were well below existing health standards. The type and magnitude of the organics depended on the material used and the test conditions.
