In this article, we report the results of the work carried out on the Verde River, a predominantly urban river located in the city of Ponta Grossa, Paraná, Brazil. Developed in three stages, it aimed to evaluate the water quality through physical-chemical parameters, the presence of caffeine as a chemical tracer, and the compound Triclosan (TCS), considered a pollutant of emerging concern. An attempt was made to identify possible polluting sources along the river. Samples were collected at 4 points from the spring region, with sampling upstream and downstream of a Sewage Treatment Plant (STP). The physical-chemical parameters were determined in situ, through portable analysers, as well as in the laboratory, in this case, through analyses using molecular absorption spectroscopy. For the determination of TCS and Caffeine, high-performance liquid chromatography (HPLC) was used, preceded by a pre-concentration step in the solid phase (SPE), and the techniques were implemented after validation. The physicochemical evaluations of the surface samples showed a decline in water quality after the STP. Mean total phosphorus concentrations of 1.0 mg∙L −1 (±0.4), as procedure, with the STP in the process called bypass. Obtaining quality data from Verde River is important for the protection of the environment and af-fects the health of the population.

A series of treaties between Lebanon and Syria on the use of the Orontes (‘Assi) River’s flows emerged in the mid-1990s, being reformed twice to result in a finalized 2002 agreement allocating Lebanon 96 million cubic meters (MCM) out of 403 MCM as measured at the Hermel Bridge gauge. Focusing on the area south of Ar-Rastan, Syria, this article seeks to explore these treaties’ treatment of groundwater, ultimately demonstrating that it is not sufficiently accounted for. This allows for intensive groundwater abstractions—which may be beyond the aquifer’s recharge rate—to be undertaken in Syria. The paper concludes with recommendations to better manage the basin’s groundwater resources, which include improving groundwater data, using these data to calibrate improved hydrologic models, and a renegotiation of the treaty to better account for groundwater use.
