Karkheh river is located in southwestern of Iran. Industrial and agricultural activities around the river contaminate it through its path. Water quality modeling from upstream of Shoosh city to downstream was simulated by QUAL2K model. In this study, we investigated how best to manage the quality of Karkheh river to be done. Nine parameters including BOD, COD, DO, PH, turbidity, nitrate, phosph...

Low levels of fecal indicator bacteria (FIB) were recently detected in two reclaimed water open-air ponds used to irrigate a golf course located in Northeastern Spain. The aim of this study was to evaluate the feasibility of a biochemical fingerprinting method to track the origin of fecal contamination in water with low FIB levels, as in the aforementioned ponds. We also aimed to determine whet...

Broiler transport coops soiled with Campylobacter-positive feces have been shown to facilitate cross-contamination of broilers. Washing and sanitizing coop surfaces do not always effectively eliminate bacteria. The objective of this study was to examine drying as a means of lowering bacterial numbers on transport coop flooring. Small squares (5 x 5 cm) of fiberglass flooring from transport coop...

Strategies are sought to reduce the impact of nonpoint sources of pollution, including fecal bacteria, and meet TMDL criteria. Vegetative filter strips (VFSs) are one such strategy. VFSs were found to be effective in removing abroad range of constituents from beef feedlot runoff pretreated by a settling basin. The first 30 m provided most or all of the reductions found within the 150-m VFSs stu...

Background; Providing Safe drinking water is a prime concerninany community. This analytical study was carried out to evaluate the microbial quality of drinking water in rural areas of northeastern Iran. Methods;The water microbial quality was determined in all villages (a population of 53047 people), in 3 rounds and based on 3 measurements, i.e. Total Coliform, Fecal Coliform, and Heterotro...

Abstract The Ciliwung River receives loads from various sources of pollution along the border, both agricultural waste, industrial and domestic waste. wastes that enter river cause a decrease in water quality. This study aims to determine quality status Jakarta segment based on Pollution Index (PI) Pesce-Wunderlin Water Quality (WQI). Monitoring was carried out February-September 2021 at 18 obs...

The aim of the study was to evaluate the presence of pathogenic viruses in the Moselle River and to compare the usefulness of thermotolerant coliforms and somatic coliphages as tools for river water quality assessment in terms of viral contamination. Thermotolerant coliforms and somatic coliphages were enumerated by standardized methods in 170 samples of river water drawn from five sampling sit...
