Investigation on Giardia and Cryptosporidium Contamination in Rural Drinking Water in a City

Objectives To investigate the status of Giardia lamblia (G.lamblia) and Crytosporidium parvum (C.parvum) contamination in source water and finished water from waterworks in Jintan, and to provide basis for the management of public health.

Methods The basic situation of 12 rural waterworks was investigated in Jintan from August to September in 2013, and one source water sample and one finished water sample was collected from each waterworks. Water samples were detected by immune-magnetic separation fluorescent antibody method based on GB/T 5750.12-2006.

Results The detection rate of G.lamblia in source water was 25.0% (3/12), and no C.parvum was detected.No G.lamblia and C.parvum was detected in finished water.

Conclusions The contamination of G.lamblia in source water in this area was positive. A light contamination of G.lamblia and C.parvum in source water could be removed by conventional processes of water treatment in waterworks.
