• In this study, a method for the simultaneous determination of two steroid hormones, 17β-estradiol (E2) and estriol (E3), and a hormone mimicking polycarbonate, bisphenol-A (BPA), was developed and validated. This was thereafter used for the determination of the levels of the hormones in surface water collected around some livestock farms. The sensitivity of the method allowed the LODs and LOQs of the hormones and mimic hormone in the range 1.14–2.510 and 3.42–7.53 μg/L, respectively. The results revealed wide variability in the concentrations of E2 and E3, while BPA was not detected at any of the sampling stations. The concentration of E3 ranged between <1.14 and 45.5 μg/L ( N  = 120) in station 2 water. The highest concentration of E2 (15.7 μg/L, N  = 80) was observed in water from station 1. The varied concentrations may be connected with the nature and sources of release, inconsistencies in analyte distribution due to dynamics of water flow pattern and the physical/chemical properties of the receiving water bodies.
