Groundwater pollution has increased as a result of poor waste disposal practices in developing countries. The purpose of this study was to determine the levels of physicochemical parameters and heavy metal concentrations in order to investigate the impact of dumpsites on groundwater and soil quality in Erinfun community. Four (4) water samples were collected hand dug well and four (4) soil samples designated Ss1 to Ss4 were collected at distances of 10, 20, 30 and 40 m, respectively, away from the waste dumpsite. Physicochemical parameters and traces such as odour, colour, taste and temperature, as well as Biochemical Oxygen Demand, Chemical Oxygen Demand, Dissolve Oxygen, Total Dissolve Solid, pH, and chloride were measured in collected water samples. Collected soil samples were also analyzed for heavy metals such as Magnesium, Zinc, Iron, Chromium, and Lead. All the physical parameters of the water samples analysed were found not to be within the acceptable limit of World Health Organization and Nigerian Standard of Drinking Water Quality standards. The chemical constituents tested were within the acceptable limit of World Health Organization and Nigerian Standard of Drinking Water Quality except for the Biochemical Oxygen Demand, Chemical Oxygen Demand and Dissolve Oxygen of water samples 1 and 2, respectively. The concentration of trace metals in water sample test were within health limit except for Magnesium and Iron which has the highest concentrations in water sample 1 at 10 m away from dumpsite (61.00 mg/l and 0.46 mg/l). Consequently, open dumpsites are discouraged, and constructed standard landfills with appropriate monitoring guidelines are recommended.

Habitat that is often found in betta fish is freshwater such as shallow waters, rice fields or tributaries. This study aimed to determine the effect of marine water giving on the survival rate of betta fish (Betta sp.). This research conducted at the Biology Laboratory of UIN Sunan Kalijaga, Yogyakarta in October 2019 with experimental research methods. The design used is RAL (Rancangan Acak Lengkap) with 5 treatments. The dose used is treatment with a dose of treatment A 0%, treatment B 25%, treatment C 50%, treatment D 75%, and treatment E 100% with maintenance for 6 days. Measured variables include life span, behavior (ethology), and water quality. The results showed that the life span of betta fish treatment A can live for 144 hours (still alive), treatment B can live for 144 hours (still alive), C treatment 8 hours 21 minutes, treatment D 2 hours 20 minutes, and treatment E 50 minutes. The observations of the treatment behavior A was calm, treatment B was active, treatment C was active, treatment D was aggressive, and treatment E was aggressive. Water quality used in the study is in the temperature range of 29o C-30o C and pH 6-8. The conclusion of this study is betta fish can survive at 25% marine water dose, while 50% -100% (absolute) treatment cannot survive, due to several factors.

The objective of the present study was to evaluate the quality of the pretreatment (in natura) and posttreatment water in the city of Jundiaí-SP. It also aims to evaluate the effectiveness of the water treatment of the municipality. Three sampling points were evaluated in the city: the source of the Jundiaí-Mirim River (p1), the accumulation dam located in the City Park (p2), and the posttreatment tap water from the distribution network (p3). The evaluation of the physicochemical parameters (dissolved oxygen-DO, hydrogenation potential-pH, orthophosphate-, nitrite-, nitrate-, ammonia-NH3 , turbidity and temperature) and microbiological (thermotolerant coliform-CT) was performed with the use of Alfakit® Ecokit II. Nonconformities were observed only in relation to the microbiological parameter: p1 presented 2,2 x 103 CFU/mL and p2, 1,8 x 103 CFU/mL; CONAMA Resolution 357/05 establishes up to 2 x 102 CFU/mL for class I. Tap water is in compliance with the reference values established by the Ministry of Health Ordinance 2914/11. The methods used were effective to certify good quality of the water after the rigorous treatment done by the DAE company, however additional studies are suggested for the identification of possible contaminants in the region.

Giardia Cysts

A total of 64 beach water samples with various bacteriological quality (Grades 1 to 4) were analysed for their bacteriological and parasitological contents (E coli and Giardia cysts respectively). Results indicated that Giardia cysts were detected in less than 10% of the Grade 1 beach water samples with E coli concentrations of <24/100mL. For Grades 2, 3 & 4 beach water samples, Giardia cysts were found, respectively, in 85, 50 and 64% of the samples. Except for one beach water sample which had an unusually high concentration of Giardia cysts (23 cysts/L), they were generally present at moderate concentrations (<10 cysts/L) in all other beach water samples. Despite moderate levels of Giardia cysts present in beach water of different grades, the potential health risk faced by swimmers bathing in local beach water needs to be carefully assessed as Giardia is known to have a low infectious dose.
