Real Time
Water Quality InformationDescription and History of ProgramThe Water Resources Management Division (WRMD) established the first near real time water quality (RTWQ) monitoring station on Leary?s Brook in St. John?s on November 5, 2001. This was implemented as a pilot station to test the feasibility of acquiring water quality information in a near real time mode.
The instruments are capable of directly measuring the following water quality parameters: The instruments use the above directly measured parameters to compute the following parameters: The
RTWQ stations are located in conjunction with Hydrometric stations so near
real time streamflow and climate information is also available. The
RTWQ stations are programmed to sample the water quality every hour with
the exception of urban sites like Leary's Brook which is sampled more
frequently. Every
three hours the RTWQ stations transmit this information through satellite
to a central repository in Maryland, USA. Water quality data is retrieved
from this central repository every two hours starting at 12:30am using the province?s Automatic Data Retrieval
System (ADRS), which automatically collects, processes and displays this
information. A
graphic depicting the system is available.
Provisional
Near Real time Water Quality and Streamflow Data displayed on these pages
are obtained from a network of gauges maintained under the Provincial RTWQ
monitoring program and the Canada-Newfoundland and Labrador Hydrometric
Network Agreement. Voisey?s Bay Nickel Company Limited looks after the
routine operational maintenance of the three stations in Labrador. Due to the volume and frequent updating of the data available on this Web site the Water Quality and Streamflow data is PROVISIONAL and has not undergone quality control checks. These data may be subject to significant change. Some of the factors that may affect the stage-discharge relationship and other water quality measurements include:
Data
are reviewed on a regular basis by WRMD personnel to ensure accuracy. Each
station record is considered PROVISIONAL until the data has undergone
Quality Assurance/Quality Control. Before
using this data in making decisions that concern personal or public
safety, substantial monetary expenditures, or other operational
consequences, users must carefully consider the provisional nature of the
information. Information
concerning the accuracy and appropriate uses of these data or concerning
other hydrologic data may be obtained by contacting Amir Ali Khan, WRMD,
