Abstract
The Water Resources Management Division of the Department of Environment and Conservation performs routine water sampling to measure the physical and chemical parameters of select water bodies in Newfoundland and Labrador. Ionic concentration parameter measurement is performed during routine water sampling to complement some of the key indicator parameters measured in real time at these select water bodies. The collection, laboratory analysis and measurement of water samples is a time consuming process. Some of the common conducting ions measured during routine sampling are sodium, calcium, chloride and sulphate. These conducting ions can be estimated using continuously measured specific conductance after observing the effect of flow. The estimated measurement will help identify whether any local stressors are affecting the quality of water at a given point in time and hence save time and resources in performing routine sampling. This can also be applied in remote locations where routine sampling is not feasible. This paper compares four water bodies on the island part of Newfoundland and Labrador and estimates the ionic concentration using continuously measured specific conductance.
Highlights
The Water Resources Management Division (WRMD) of the Department of Environment and Conservation (ENVC) of the Province of Newfoundland and Labrador (NL) has established a near real time water quality (RTWQ) monitoring network throughout the province where key indicator water quality data are collected continuously
The grab sampling is part of the Quality Assurance/Quality Control (QA/QC) protocol for NL RTWQ program which is used to compare the accuracy of the real time parameters against those measured at an accredited laboratory
This paper shows that it is possible to optimize the resources and sampling time resulting in overall cost and time savings under the RTWQ Program using real time ionic concentration estimation
Summary
The Water Resources Management Division (WRMD) of the Department of Environment and Conservation (ENVC) of the Province of Newfoundland and Labrador (NL) has established a near real time water quality (RTWQ) monitoring network throughout the province where key indicator water quality data are collected continuously. Percent saturation and total dissolved solids are two additional parameters calculated from DO and SC These key indicator parameters provide significant information to better understand the water quality of a particular water body. The collection, shipping and analysis of grab samples in the laboratory require a significant amount of time to measure the ionic concentration of the sample contents and provide the results
