HELLO, everyone , my name is shiepng Fu. I’m glad to introduce my project “”
Department of Civil Engineering
University of Texas

2. Austin,1990
Austin,2000
In the last 10 years, the growth of the population in austin is almost double. The city of austin experienced a great . Urban construction and urban could cause groundwater hydrological process change. 2My project is to investigate the impact of urbanization on the quality of ground water.

3. Site locations for monitoring wells
This picture is the map of the city of Austin And it is also the base map of my project. And these red spots are the monitoring wells in austin.
Data source: City of Austin

4. Data Source: City of Austin
This figure shows the collected data about ground water quality in the city of Austin from 1986 to It was observed that the year of 1998 has the most comprehensive data. So, in my project the year of 1998 was used as the representative to evaluate the ground water quality.
Data Source: City of Austin

5. Parameters for Water Quality
Fecal Coliform
Total Phosphorus
pH value
In the project, 3 parameter were chosen to characterize the water quality.

6. Fecal Coliform

7. fecal coliform mean concentrations in Austin, Texas in 1998 and early 90’s

10. Trend Analysis of fecal coliform of 1998

11. Total Phosphorus

12. current total phosphorus concentration distribution
Concentration (mg/l)

13. Total Phosphorus Animation
Total Phosphorus Concentration (mg/l)

14. pH value

15. current Ph value distribution

16. Data source: Lower Colorado River Authority
Discharge points

17. In Summary
The groundwater quality degraded with the growth of population.
By using GIS, Total phosphorus and fecal coliform concentration are readily observed to be significantly related to the waste discharge, but pH value is not.

18. Work in progress
Find Population Density Data associated with the area that has relatively worse groundwater quality
Find land use data associated with the area that has relatively worse groundwater quality

19. Thank you
