Among 216 samples from the reservoir, most contained acceptable levels of micro-organisms and none contained toxic substances. In some of the samples, however, there were higher than acceptable levels of pollution from materials including heavy metals and ammonia. Samples containing pollution were mostly taken from the area near the shore in Dinh Quan District.
Based on these results, the provincial authority has asked departments, industries and localities to continue supervision to prevent fish breeding in pools, dams and channels along Tri An Reservoir. Authorities also urged serious measures to be taken in cases of improper licensing for the use of land surrounding the lake and pollution-producing activities.
