Abstract Background:The study conducted a comprehensive assessment of the quality of selected groundwater sources around the liquid waste treatment plant of Ahmadu University Teaching Hospital Shika, Nigeria. Water samples were collected from four (4) hand-dug wells following standard procedures, ten (10) physicochemical parameters and seven (7) heavy metals were analyzed.Results: All the physicochemical parameters studied were within the WHO specified limits except for DO which was less and turbidity which was higher. Heavy metals were found in the all the groundwater sources that were studied. However, the concentration of some heavy metals exceeded the specified limits recommended by the World Health Organization (WHO). The heavy metal presence in the groundwater sources may be connected to human activities such as waste disposal containing these metals around the groundwater sources and liquid waste from the hospital which can may have seeped into the wells.Conclusion: By implication, this study shows that the hand-dug wells were not safe for drinking. It is recommended that wells be sited away from dumpsites and waste treatment plants and effluents from waste treatment plants should also be properly treated before their subsequent discharge into the environment. This study has generated a baseline data that will be useful in monitoring heavy metal pollution.

This summary presents the cleansing and dismantling operations currently realized on the CEA center of Saclay (CEA-Saclay). It was initiated at the beginning of the 2000 years a cleansing and dismantling program of the old Nuclear Licensed Facilities (NLF). Currently this program relates to the Hot Laboratories (Laboratoires de Haute Activite´: LHA) and the old workshops of the Liquid Waste Treatment Plant (Station des Effluents Liquides: STEL).

This summary presents the cleansing and dismantling operations currently realized on the CEA center of Saclay (CEA-Saclay). It was initiated at the beginning of the 2000 years a cleansing and dismantling program of the old Nuclear Licensed Facilities (NLF). Currently this program relates the dismantling operations to the Hot Laboratories (Laboratoires de Haute Activité: LHA) and the old workshops of the Liquid Waste Treatment Plant (Station des Effluents Liquides: STEL), the dismantling preparation of ULYSSE reactor and the dismantling studies to the Solid Waste Management Plant (SWMP; Zone de Gestion des Déchets Solides) and the OSIRIS reactor.

The quality of environment especially the water bodies need to be improved on the pollution load of the household wastewater, which in general still does not have a liquid waste treatment plant. Electrocoagulation used in this research because of the simple and efficient method. The aim of study to know the ability of electrocoagulation method for reducing the concentration of COD and TSS in the wastewater from household textile industry.  The sample was taken from the residual wastewater of textile dye (sarung) with a liquid waste requirement of 36 liters. The data for the analysis is the initial and final parameters data were COD and TSS. The electrodes were used aluminum (Al) as an anode and iron (Fe) as a cathode. The research variations were used the number of electrodes and the voltage. The results showed that the treatment of 4 electrodes with 12volt voltage could reduce the COD concentration up to 76% and TSS up to 85% in household wastewater of household textile industry. Keywords: COD, electrocoagulation, liquid waste, TSS

Biosorption is a new waste treatment technology that can eliminate toxic heavy metals. Biosorption can be considered as an environmentally friendly alternative technology to treat industrial liquid waste that is economically proper to use. One of them is biosorption that utilizes the microorganisms’ absorption ability, especially bacteria that can absorb heavy metals in waters, such as Enterobacter agglomerans. This research aimed to determine the ability of E. agglomerans in reducing heavy metals pollution in local river. The research employed the measurement of the effect of lead (Pb) to E. agglomerans growth using Optical Density (OD) at wavelength 600 nm. The colony numbers were calculated using a standard curve. While the ability of E. agglomerans to reduce heavy metals concentration in liquid media was measured using AAS with a wavelength of 240 nm. The results showed that lead affected the growth of E. agglomerans. The OD value has a negative relationship with the concentration level of Pb. The ODs were decreased from 2.867 to 1.242, using Pb level from 0 ppm to 20 ppm. Therefore, it proved that E. agglomerans could reduce heavy metals concentration in local river in Central Java Province. This research was the first report on E. agglomerans activity on heavy metal in contaminated water. This result can be used as a reference for industrial sites near the river to treat their wastewater before discharging it to the river body to preserve its water purity.

Animal Sluaghterhouse (RPH) liquid waste contains organic matter, suspended solids, and colloid materials such as fat, protein, and cellulose with high concentrations that fall into the category of complex wastewater. RPH X is a RPH that uses Water Waste Treatment Plant (WWTP) in treating wastewater, although it has been equipped with WWTP there are still some problems in RPH X. The purpose of this research is to describe wastewater treatment and content of BOD, COD, TSS, NH3-N, pH and fatty oil at waste water in inlet and outlet of IPAL RPH X, Jember District. This research is a descriptive research. Technique of data collecting done by observation, interview, and laboratory test. The average of wastewater content test result in RPH X Jember Regency at inlet and outlet of IPAL is at safe limit of quality standard according to East Java Governor Regulation Number 72 Year 2013 except COD parameter at inlet that is equal to 277,6 mg / L. The average percentage of content in liquid waste in RPH X decreases from inlet to WWTP outlet except the pH parameter.
