Local Water Supply Plan Template –July 8, 2016 15 Table 8. Information about source water quality and quantity monitoring MN Unique Well # or Surface Water ID Type of monitoring point Monitoring program Frequency of monitoring Monitoring Method See SPRWSP ☐ production well ☐ observation well ☐ source water intake ☐ source water reservoir ☐ routine MDH sampling ☐ routine water utility sampling ☐ other ☐ continuous ☐ hourly ☐ daily ☐ monthly ☐ quarterly ☐ annually ☐ SCADA ☐ grab sampling ☐ steel tape ☐ stream gauge Water Level Data A water level monitoring plan that includes monitoring locations and a schedule for water level readings must be submitted as Appendix 2. If one does not already exist, it needs to be prepared and submitted with the WSP. Ideally, all production and observation wells are monitored at least monthly. Complete Table 9 to summarize water level data for each well being monitored. Provide the name of the aquifer and a brief description of how much water levels vary over the season (the difference between the highest and lowest water levels measured during the year) and the long-term trends for each well. If water levels are not measured and recorded on a routine basis, then provide the static water level when each well was constructed and the most recent water level measured during the same season the well was constructed. Also include all water level data taken during any well and pump maintenance. Add rows to the table as needed. Provide water level data graphs for each well in Appendix 3 for the life of the well, or for as many years as water levels have been measured.

If known, provide the name of specific resources that may be impacted. Identify what the greatest risks to the resource are and how the risks are being assessed. Identify any resource protection thresholds – formal or informal – that have been established to identify when actions should be taken to mitigate impacts.
