As a major part of the 2006 World Water Monitoring Day in Hong Kong campaign, the
20 participating schools are required to carry
out sampling tests for different water sources by the use of the five no. of test kits provided.
The participating schools had attended a briefing on 3 October 2006 regarding the selection of test
sites, use of the test kits and reporting requirements before starting the sampling tests. Many of
the schools chose to perform their tests in the small streams lying within catchment areas around
local impounding reservoirs such as Tai Lam Chung and Plover Cove, or streams in their schools'
nearby. The choice of these test sites was in line with the objective of the World Water Monitoring
Day, ie to monitor the conditions of different raw water sources. The test results showed that the
pH of water in these test sites was within the range of 6 to 8, the dissolved oxygen level ranged
from 4 to 8 ppm while the turbidity was less than 40JTU in general. It can be concluded from these
test results that the quality of water was free from serious pollution. Examples of good reports
can be found by clicking here. Selected photos
of the reports are available in the Photo Gallery.
