The Use of Phytoplankton as Water Quality Indicator Together with Basic Water Quality for Reservoirs of Eastern Thailand
Abstract
Reservoirs are one of the most important freshwater sources for consumption, agriculture and industrial plants. But because of the closed water system, so the water in reservoir could not be circulated in/outside. This could lead to the water deterioration if the pollutants were contaminated. This research aimed to use the phytoplankton as an indicator of essential water quality at 3 reservoirs, Bangphra, Dokkrai and Nongplalai reservoir located in the eastern region of Thailand. The study period was 5 months (August – December 2020) and the monthly sample collection was carried out from the total of 9 stations. The phytoplankton samples were collected and then analyzed the dominant genus using the microscope. Some parameters of water samples were also investigated including DO, BOD, chlorophyll, nitrate, ammonia and phosphate. The water quality levels were analyzed by AARL-PP Scored method using the 3 dominants genus of phytoplankton and the AARL-PC Score method was also used. All results indicated 3 divisions, 21 genus of phytoplankton, including division Cyanophyta 9 genus, Chlorophyta 6 genus and division Chromophyta 6 genus. The results also indicated the water quality levels by AARL-PP Score method in BangPhra, DokKrai and NongPlaLai reservoir in the range of "moderate to pollute" to " pollute" (Meso-Eutrophic to Eutrophic condition). By AARL - PC Score method, the results of water quality levels were found to be in the range of “clean – moderate” to “moderate” (Oligo-Mesotrophic to Mesotrophic condition) which were one level difference. From the results in overall, the phytoplankton could be used as a basic indicator of water quality for reservoirs. However, the increasing number of water sample collections and inlet stations should be considered for the accuracy improvement. The results could also be used as the primary database in water quality management for the reservoir.
