Integral Index of Water Quality: A New Methodological Proposal for Surface Waters
نویسندگان
چکیده
A methodology is proposed aimed at defining an integral index of water quality in surface waters that incorporates the information for five variables currently used to independently measure condition Cupatítzio River, Michoacán. The considered were current by CONAGUA, concentration metals, biodiversity as assessed through BMWP index, microbiological values Escherichia coli, and level toxicity. was applied 17 sites along Cupatitzio riverbed dry season 2017. Each variable assigned a rank, which standardized scale 1–10 subsequently multiplied weight (W) numerically represented degree importance influence each factor had terms pollution. These factors depended on anthropic area, with value 5 indicating method most significant impact 1 least. (IIWQ) calculated arithmetic sum considered, generating single value. It intervals 15 points minimum 150 maximum. Five levels proposed: excellent, good, fair, bad, very bad. results showed that, studied, majority (ten) fair category, ranging from 69 95 points; six good category (96 122 points); only one bad (42–68 points). With application this incorporating already described, it possible assess conditions River adequate suitable its uses different socioeconomic activities destined.
