Capturing how the well behaves right after pumping starts is essential. Drawdown can change very quickly at the beginning, as the aquifer and well respond to the new flow rate. Recording measurements every minute during the first hour provides a detailed, high-resolution record of that rapid change, helping you identify the initial drawdown trend and any fluctuations caused by well efficiency or aquifer response. Once the first hour has passed and the rate of change slows, you can switch to longer intervals—every 10 minutes—to continue tracking the curve without overloading data collection. This approach gives a precise early profile and a practical, steady later profile, which is why measuring every 1 minute initially, then every 10 minutes, is the best method.
