“…For this purpose, a resistivity meter (SYSCAL, direct current by IRIS INSTRUMENTS) was utilized. The multinode, multi-electrode acquisition system comprises 10 channels, a current transmitter powered by a power converter, allowing the generation of substantial voltage differentials from a 12-volt battery [18].…”

This research addresses potential saline intrusion in a coastal tourist city such as Puerto Vallarta, a significant tourist hub on the Mexican Pacific coast, where water production and consumption are close to the equilibrium point. Overexploitation and proximity to the ocean threaten its sources of supply. The objective is to explore the possible saline intrusion that occurs when salt water mixes with groundwater sources for human consumption. Various factors, such as the overexploitation of aquifers, highlight the need for effective management of water resources in coastal tourist cities due to the growing pressure on this resource by the population and visitors. The study commences with an exploratory analysis of a water extraction source located in the Pitillal River basin, with suspicions of elevated chloride levels. Employing hydrogeophysical analysis to measure the electrical resistivity of subsurface materials, the research determines their characteristics and distribution. Results indicate low resistivity at 14-20 meters depth, associated with water containing chlorides. On-site verification reveals a concentration of 301 mg/L of dissolved chlorides, surpassing the recommended 250 mg/L for human consumption according to the World Health Organization and the Official Mexican Standard. Therefore, ongoing studies in other nearby sources are crucial to assess contamination risks and enhance strategies for water use efficiency or explore new sources, ensuring sustainability and water security in the region.

Duckweed (Lemna minor L.) has attracted considerable attention in the scientific field due to its nutritional contribution and capacity to phytoremediate waters. Therefore, the objective of the study was to analyze the chemical composition of the macrophyte (Lemna minor) from natural environments. Chemical compounds and Weende composition were determined from the plant, and the fresh weight gain was observed in different types of water (deep well and bovine slurry), waters that were subjected to physical-chemical analysis. The chemical analysis of the macrophyte resulted in the presence of 1.42 mg.g-1 of total chlorophyll; 2.35 mg.kg-1 of ascorbic acid; tannin content less than 2.50 mg.kg-1; 45.34 mg.kg-1 of phenols; also the presence of alkaloids, phenols and reducing sugars in the chemical screening. The Weende analysis indicates a composition of: 89 % of dry matter, 30 % of crude protein, 4 % of gross energy, 3.2 % of ether extract, 15 % of ashes, 32 % of nitrogen-free extract and 10 % of fiber. The fresh weight gain of Lemna minor obtained in water contaminated with bovine slurry increased significantly 13 g.day.m3 and 5 g.day.m3 in deep well water. The physical-chemical properties of the water improve their quality 16 days after treatment with this aquatic plant with respect to the initial analysis. This macrophyte exhibits remarkable phytoremediation properties to absorb, metabolize and stabilize various pollutants effective in the purification of contaminated waters.
