North County RC&SL Public Works/Solid Waste <br />First Semiannual 2024 Groundwater Monitoring ©2024 COUNTY of San Joaquin. All Rights Reserved. <br /> <br />The groundwater flow velocity was 34 ft/yr was calculated as follows: <br /> <br /> V = 10,100 ft/yr (0.001 ft/ft) <br /> 0.30 <br /> = 34 ft/yr <br /> <br />Second Quarter 2024 <br />Between wells G-7 and G-12 <br />The hydraulic gradient (0.005 ft/ft) was calculated by dividing the difference in <br />groundwater elevations between wells G-7 and G-12 by the horizontal distance between <br />the two wells (1,700 feet). <br />The groundwater flow velocity was 168 ft/yr was calculated as follows: <br /> <br /> V = 10,100 ft/yr (0.005 ft/ft) <br /> 0.30 <br /> = 168 ft/yr <br /> <br />Between wells G-10 and G-7 <br />The hydraulic gradient (0.0001 ft/ft) was calculated by dividing the difference in <br />groundwater elevations between wells G-10 and G-7 by the horizontal distance between <br />the two elevations in the direction of groundwater flow (2,100 feet). <br />The groundwater flow velocity was 3.4 ft/yr was calculated as follows: <br /> <br /> V = 10,100 ft/yr (0.0001 ft/ft) <br /> 0.30 <br /> = 3.4 ft/yr <br /> <br />Between wells G-10 and G-9 <br />The hydraulic gradient (0.001 ft/ft) was calculated by dividing the difference in <br />groundwater elevations between wells G-10 and G-9 by the horizontal distance between <br />the two elevations in the direction of groundwater flow (2,200 feet). <br />The groundwater flow velocity was 34 ft/yr was calculated as follows: <br /> <br /> V = 10,100 ft/yr (0.001 ft/ft) <br /> 0.30 <br /> = 34 ft/yr <br />
