    Abstract: This article attempts to appraise the groundwater water quality of Pariya, Nigeria. Water samples was collected from 10 different borehole sources in the study area and analysed for the physicochemical factors such as pH, TDS, Total Hardness, Calcium, Magnesium, Sodium, Potassium, Chloride, Sulphate, Lead, Fluoride, Iron, Bicarbonate and total coliforms. The results of physicochemical quality was compared with the WHO standards. It was found that the physicochemical quality was within the permissible limits. The bacteriological analyses indicated the occurrence of total coliforms above the standards. It was recommended to adopt basic treatment by boiling before ingestion to safeguard against water borne diseases

    Tropical peat swamp forest (PSF) is one of the most endangered ecosystems in the world. However, the impacts of anthropogenic activities in PSF and its conversion area towards fish biodiversity are less understood. This study investigates the influences of water physico-chemical parameters on fish occurrences in peat swamp, paddy field and oil palm plantation in the North Selangor peat swamp forest (NSPSF), Selangor, Malaysia. Fish and water samples were collected from four sites located in the peat swamps, while two sites were located in the paddy field and oil palm plantation areas. Multivariate analyses were used to determine the associations between water qualities and fish occurrences in the three habitats. A total of 1,382 individual fish, belonging to 10 families, 15 genera and 20 species were collected. The family Cyprinidae had the highest representatives, followed by Bagridae and Osphronemidae. The most abundant species was Barbonymus schwanefeldii (Bleeker 1854), while the least abundant was Wallago leerii Bleeker, 1851. The paddy field and oil palm plantation area recorded significantly higher fish diversity and richness relative to peat swamp (p0.05), but was significantly different from the peat swamp (p<0.05). However, no water quality parameter was consistently observed to be associated with fish occurrences in all of the three habitats, but water temperature, NH3-N, Cl2, SO4, and EC were at least associated with fish occurrences in two habitats studied. This study confirmed that each habitat possess different water quality parameters associated with fish occurrences. Understanding all these ecological aspects could help future management and conservation of NSPSF
