abstract
The importance of knowing the water quality status with the use of macroinvertebrates diversity gives an establishment to proper practices to prevent pollution in Surigao River, Surigao City, Philippines. Riparian, Channel, and Environmental Inventory were used in describing the vegetation of the three-sampling stations. The occurrence of macroinvertebrates was supported by selected physicochemical parameters, WQI, and ASPT. RCE scores for the three sampling stations were good, very good, and fair. physicochemical parameters were within standard limits of DAO 2016-08 except for pH and temperature for station 1. WQI results, stations 1 and 2 were "rather dirty-water average," while station 3 was "dirty" Stations 1 and 2 were rated as "moderate," while station 3 had a rate of "very poor in ASPT. There were 13 aquatic macroinvertebrates collected from the 12 families, including Annelida (9%), Arthropoda (30%), and Mollusca (61%). There was an absence of EPT and station 2 was the most diverse. Constant monitoring, particularly for the improvement of riparian zones, heavy-metal tests, and microbiological parameters, should be conducted to relieve and manage the existing problems of water quality status.
