River water quality measurement in Ecuador

A monitoring program enabled the evaluation of water quality and the simulation of the pollution dynamics of the rivers in the Joya de los Sachas and Francisco de Orellana cantons in Ecuador. One used the WQI (water quality index) and the pollution indices ICOMO (organics contamination), ICOSUS (suspended solids), ICOMI (mineralization), ICOTRO (trophy system), and ICOpH (pH Index). The mathematical model operates with several input parameters, including dissolved oxygen, fecal coliforms, the biochemical oxygen demand (BOD5), turbidity, total solids, total phosphorus, pH, total nitrogen, suspended solids, alkalinity, conductivity, temperature, and the concentrations of nitrates, nitrites, and phosphates. WQI values were obtained from ICO pollution indices. The pollution of the Sacha area is significant, WQI = 0.292, which represents an advanced degree of pollution since increased BOD values correspond to a high load of organic pollutants. They can originate from household, agricultural,..., Study Area
The study area of this project included the experimental farms of the examined components in the Parishes San Carlos, San Sebastián del Coca, Tres de Noviembre, San José de Guayusa, the Joya de los Sachas and Francisco. Investigated were the experimental farms of Orellana components, in the Province of Orellana, which correspond to an area of 1205.6 km2. Four reference points have been selected for sampling on the Sacha River and on the Basura River experimental estates.
Methodology
To assess the water quality and simulate the pollution dynamics of the rivers in the Joya de los Sachas canton for agricultural use, preservation of aquatic life, and recreation, one sampled and characterized river water at the monitoring points. Subsequently, one performed calculations and analysis of quality indices WQI, ICOMO, ICOSUS, ICOpH, ICOTRO, and ICOMI.
Sampling and characterization of monitoring points
 The sampling points were selected by considering the use of oil, anthropogenic ..., , # Water quality by applying IQA and ICOs

#### **Description of the data and file structure**

The main goal of the authors' experimental effort for which the data was collected: to establish a monitoring program for checking whether the physical, chemical, and biological characteristics of rivers near the project area represent a climate-smart production system. Also, one aimed to determine synergies between mitigation, adaptation, and food security measures implemented since 2017 by the Causana Yachay Group. For establishing such synergies, one should document whether they meet the requirements for agricultural use, conservation of aquatic life, and recreation.

One evaluated the quality of river waters via mathematical models that revealed the approximate quality parameters at points where the water was monitored starting in October 2019 until February 2020. Models were used to simulate the dynamics of pollutants and compare different rivers. ...,
