The present study examined some physico-chemical characteristics (temperature, pH, total hardness, dissolved oxygen (DO), total dissolved solid(TDS), conductivity, transparency, biochemical oxygen demand (BOD), acidity and alkalinity) and some heavy metals (Fe, Zn, Cu, Cd, Cr and Ni) concentration of Stubbs Creek, Ibeno, Akwa Ibom, Nigeria between August 2014 and July, 2015. Six sampling stations (Mkpanak, Okpot Ikot, Ebana Mbri, Esit Eket, Okpuk and Ikot Ebia Anam) in Stubbs Creek were selected. Water samples were analyzed using APHA-AWWA-WPCF methods while heavy metals in the water samples were digested and determined using UNICAM 939 Atomic Absorption Spectrophotometer (AAS). The mean values of water parameters of Stubbs Creek are: temperature (27.22 ± 0.230C); pH (6.83 ± 0.13), DO (3.86 ± 0.20 mg/L), BOD (2.84 ± 0.11 mg/L), conductivity (522.23 ±69.12 µScm-1), TDS (288.83 ± 39.50 mg/L), transparency (0.86 ± 0.05m), alkalinity (95.51± 6.44mg/L), acidity (97.03±7.45) and total hardness(12.11±1.55).Only TDS, conductivity, alkalinity and total hardness showed significant (p<0.05) spatial variation across the sampling stations. However, the values of temperature, TDS, conductivity, alkalinity and total hardness indicated significant seasonal variation. Similarly, there were no significant (p<0.05) spatial and seasonal variation in the values of heavy metals recorded across the sampling stations. All the physico-chemical parameters and heavy metals in this study are below the maximum permissible limit recommended by WHO. The result showed that Stubbs Creek is less polluted at present and safe for the biota. However, responsible use of the water bodies by all and sundry should be maintained in order to preclude problems common with effluents discharge.

Developing countries like Nigeria are faced with increased in generation of domestic, industrial and agricultural wastes, with a large percentage moving. This study evaluates the physico-chemical and some heavy metals concentration in three common species of fish from Tungan Kawo reservoir Kontagora, Nigeria; using standard methods between (July 2018 – February 2019); at four different sampling stations of human activities on the water. Five heavy metals were evaluated (Lead, Copper, Manganese, Iron and Chromium) in the fish samples. Phosphate (0.4 – 2.5) mg/L, Nitrate (3.2 – 7.5) mg/L, Temperature (27 – 32.4) 0C, Dissolved Oxygen (2.4 – 5.2 mg/L), Conductivity (81 – 125 µS/cm), Biochemical Oxygen Demand (1.9 – 4.4 mg/L), Alkalinity (mg/L) and Total Dissolved Solids (117 – 198) ppm were within the standard for drinking water and survival of fish.  However, the pH (6.3 – 9.8) was above the standard for NIS and WHO drinking water but can support aquatic life. Iron (0.64 ± 0.072 mg/kg) was the most highly concentrated in Synodontis clarias while lead (0.01 ± 0.013 mg/kg) was the lowest in Oreochromis niloticus and Coptidon zillii (formerly Tilapia zillii. This current finding indicates that the water is safe for both aquatic life and domestic purpose but not suitable for direct human consumption without being properly treated. However, there is the need for regular monitoring of the heavy metals load in this water body and the aquatic organisms because of the long term effects

A physico chemical and microbiological study of the ground water of some villages of Surat district of Gujarat state (India) has been made. Physico chemical parameters such as colour, odour, taste, temperature, pH, electrical conductivity, TS, TDS, total hardness, total alkalinity, calcium, magnesium, iron, sodium, potassium, chloride, sulphate, nitrate, fluoride and silica were determined. In microbiological study, total coliforms, E. coli, sulfate reducing anaerobic bacteria, pseudomonas aeruginosa, yeast and mould were investigated. Samples were taken from ten sampling points in ten different villages viz. Parvat(S-1), Kharvasa(S-2), Bonand(S-3), Vesu(S-4) Amroli(S-5), Kadodara(S-6), Chalthan(S-7), Variyav(S-8), Gaviyar(S-9) and Bhairav(S-10). Samples were taken four times in year in the month of May, August, November and February to check the seasonal effects. In village Gaviyar, Gujarat Water Supply and Sewerage Board has set up a treatment plant to supply good quality potable water in few surrounding coastal villages. In all other cases samples were taken from bore-well. Here study reported is for samples taken in May-2004 and August-2004.For colour, iron, sulphate, nitrate, fluoride and silica, instrumental methods like spectrophotometry were used. “Hach-Odyssey spectrophotometer” which has facility to store calibration curves and which can display the value for that parameter directly was used. In present study programmes of “Hach” with their reagents were used while some programmes were prepared by us using our reagents. This is an excellent instrument and results of this instrument are validated by USEPA. Sodium and potassium was determined using flame photometer. It was found that some water samples have higher TDS, chlorides, total hardness and total alkalinity than the permissible limits. In all cases samples were not found to contain significant quantities of bacteria and water was palatable from this point of view.

The protection of our environment from pollution by various industrial wastewater discharges is of great importance that each Industry treats its effluent to meet acceptable limit/design means to reclaim water from industrial effluents for re-use. The study aimed at reclaiming water from wastewater by assessing the performance of two cellulose adsorbents using the fixed-bed column method to treat pharmaceutical/metal wastewater. The study was carried out by determining the physico-chemical and microbiological parameters of wastewater quality before and after treatment using fixed-bed column. Effluent samples were collected and analyzed according to standard methods. The range of percentage reduction in pollution load with respect to treatment time: 30, 120, 360 and 1440 min was 45-52%, 55-64%, 31-43, 25- 45%, 41- 44%, 55-73%, 48- 51%, 48-54%, 56-71% 13-31%, 45-52%, 47-67% from the metal effluent using nanocellulose adsorbent while 14-24%, 18-23%, 4-10%, 28-46%, 16-20%, 24-42%, 14-32%, 42-57%, 32-52%, 36-47%, 37-56%, 8-53% from the pharmaceutical effluent using oxidized cellulose adsorbent for colour, turbidity, conductivity, total hardness, Nitrite, Phosphate, Ammonia, Biochemical Oxygen Demand, Chemical Oxygen Demand, total solids, total suspended solids and total dissolved solids respectively. Up to 99.9 % was achieved by the adsorbents in the removal of biological contaminants. The study concluded that the celluloses adsorbents showed promising potentials as one-point adsorbent that can be used for water reclamation from wastewater by its ability to remediate both physico-chemical and bacteriological contaminants.

Water plays a key role in the survival, growth and reproduction of aquatic organisms. Therefore maintaining good quality of water physico-chemical parameters would ensure optimum productivity of aquatic fauna. The study evaluated water physical and chemical parameters (temperature, hydrogen ion concentration (pH), conductivity, dissolved oxygen (DO) and biochemical oxygen demand (BOD) of Bodo Creek. Sample was collected for 5 months (July 2020 – November 2020) at locations previously studied (before-spill baseline studies, 3 years, 5 years, and 7 years after-spill); by using the sampling methods used in previous studies. Spatially, there was no statistically significant difference in temperature (p > 0.05 = 0.997), pH (p > 0.05 = 0.496), DO (p > 0.05= 0.34) and BOD (p > 0.05 = 0.644). However, the difference in conductivity between the stations was statistically significant (p < 0.05 = 0.006). On monthly basis, there was a significant difference in temperature (p < 0.05 = 0.000) and pH (p < 0.05 = 0.005). In contrast, there was no statistically significant difference in conductivity (p > 0.05 = 0.633), DO (p > 0.05 = 0.559) and BOD (p > 0.05 = 0.75). Most of the physico-chemical parameters were not within the WHO recommended levels for the survival of aquatic lives, indicating a high level of environmental pollution in Bodo Creek. This study provides dataset for future evaluation of the water physico-chemistry of Bodo Creek.

Pollution resulting from unsustainable agricultural and urbanization activities in the Ruhezamyenda and Bunyonyi catchments are threatening lake Bunyonyi. These have led to high chemical oxygen demand (COD), electrical conductivity, turbidity, pH, iron (II) concentration and low dissolved oxygen (DO5). In this study we have investigated the how COD, turbidity, pH, concentration of iron, total suspended solids, total nutrients and DO5 of water changed with distance in lake. Water sampled from different distances in the lake filtered using Whatman paper at ambient temperatures was tested for COD, electrical conductivity, turbidity, total nutrients, iron, hardness and DO5. COD was 20.8±.0.03mg/L to 16 ± 0.03mg/L; total hardness was 16.5±0.2 mg/L to 18.6 ± 0.3 mg/L total nitrate was 103.5± 2 mg/L to 88 ± 3 mg/L; total phosphate was 100.8 ±.2.5 to 87± 3 mg/L; high TSS values from 3.4 ± 0.1 mg/L to 2.5 ± 0.1 mg/L showed contamination of water. As pH decreased from 8.3 ± 0.03 to 7.6 ± 0.04 revealed that bases were getting removed. The turbidity dropped from 25.7 ± 0.3 NTU to 20 ± 2 NTU due settling down of sediments. Iron (II) concentration ranging from 1.1± 0.1 to 0.8± 0.1 mgL-1 . Dissolved oxygen decreased from 7.9 ±0.3 mg/L to 4.8 ± 0.2 mg/L indicating surface water can uphold life of aquatic organisms. Total hardness ranged from 0.22± 0.05 to 0.19± 0.05 mg/L Electrical conductivity was high and ranged from 130± 5 to 150± 5 µS/cm indicating presence of electrolytes. Lake Bunyonyi water is not greatly polluted, but requires to be safe guarded against poor unsustainable agricultural practices, sewage draining from towns, schools and hotels in nearby settlements.
