This Nanoose (Area E) Water Monitoring will see expanded data collection within the geographical area, resulting in a higher resolution understanding of groundwater and surface water characteristics in Nanoose. This will enable more accurate water budget calculations that look at supply, demand and resulting stress level. Ultimately this information will be used to support sustainable development decisions and protect water resources over the long term.
In 2016 a water monitoring plan for Area E as a whole was developed; click here to see the report. In the summer of 2017, 5 new volunteer observation wells will be added within the area, to fill spatial gaps in groundwater level data. A streamflow monitoring station has also been added on Nanoose Creek as of February 2017.
B1 â€“ the RDN well on Parker Road â€“ pumping history is as follows:
Water levels in the bedrock wells, particularly in the summer months, are influenced by the cumulative effect of all bedrock wells pumping in the vicinity.
Water levels in the overburden (sand and gravel) wells do not appear to react to pumping in the bedrock aquifer.
The next data download will take place in the early spring, to observe how aquifer levels respond over the winter season.
Further background info:
The purpose of the 72 hour pump test was to intentionally stress the well in order to understand the connection and response in other nearby wells. This is standard professional practice in well assessment procedures. The 72 hour pumping test was run at 105 US gpm, which is a much higher rate than a community well would ever be operated at. The test was successful in identifying relationships between wells that will allow us to determine safe, sustainable operating rates for the well that will not significantly impact the functioning of neighbouring wells.
Please note that short term deviations in conductivity readings in the proposed community well during the 72 hour test is largely due to instrumentation errors and re-calibration resulting from flow velocity changes at the beginning and at the end of the test.
Also note that during the 72 hour pump test, all data loggers were reprogrammed to collect water level readings at 1 minute intervals. Therefore if the water level graph looks different in the wells between Oct. 19-26, it is for this reason; there are more data points being recorded and so more pumping events are observed in the graph.
Notes from meetings with the residents of the Parker Road area:
Results of the first year of monitoring (April 2015 - April 2016) provides a baseline understanding for the 15 wells in the Parker Road area. This analysis is included in the report: "Rating and water quality of the proposed community well at 2729 Parker Road after a 72hr Constant Rate Test; and results of 1-year Baseline Monitoring of 15 Wells".
