- (a) Well yield shall be measured periodically during well construction when there is a readily observable change in yield.
- (b) A well shall be flushed or surged to remove debris and by-products of the construction process.
- (c) A well constructed in unconsolidated materials shall be surged or pumped to develop yield and remove fine soil particles.
- (d) The final yield shall be measured for all new wells, after development, and indicated on the well completion report.
- (e) For wells yielding more than 5 gallons per minute (GPM), yield measurement shall be for a minimum of 15 minutes.
- (f) For wells yielding 5 gallons per minute or less, yield measurement shall be for a minimum of 30 minutes after dewatering the hole and until the flow has stabilized.
