A total head drop of approximately 0.13 feet was measured during the entire test duration <br />(approximately 61/2 hours). <br />2. Due to the very low infiltration rate observed, there were no repeated stages during testing. <br />3. The pre-soak period is intended to saturate the soil and is not taken to be the long-term <br />infiltration rate. <br />4. The estimated field measured infiltration rate is 0.23 inches per hour. <br />6 <br />Stage # <br />8 <br />10 <br />PIT-2 Infiltration Rates <br />12 <br />Baker Heights Redevelopment <br />Everett, Washington <br />GWENGINEERS �TF!gurelI3 <br />
