Read the City's water quality protection publications.
We have developed a watershed viewer, so it is easy to find out what watershed you live in and to find out its Environmental Integrity Index score.
Contact Sara Heilman, email or phone 512-974-3540. Allow at least 2 hours for field trips (caving and creek testing). Bus fees will be reimbursed.
Contact Sara Heilman email or phone 512-974-3540. Our training kit contains 6 sets of the following kits: Dissolved oxygen, pH, TDS, nitrate, and E. coli. The kit may be checked out and we provide training for your students if required. You may also request one free complete test kit.
Water test kits are available for teachers and classes for educational use. General use kits may be requested through Keep Austin Beautiful
Contact Sara Heilman for specific information about your school's watershed, maps and curriculum on non-point source pollution and land use.
Part 1 View the presentation, then illustrate your concept of point source and non point source pollution
Part 2 Use the information on the site Protecting Water to answer the questions on the student sheet.
Part 3 A. Spills data
Follow directions on the student sheet and answer questions 1-6
B. Contour maps Permitted business data Use the contour map of your watershed, 2000 land use map of your watershed, and the data to answer questions 7-8.
Part 4 Use information from the Watershed Viewer Follow directions on student sheet and answer questions 11-16.
Land use and Water Quality in your Watershed
Goal Students learn how land use affects water quality.
Objective Students will:
Time Two to three, 45 minute class periods (may need another class period to finish research)
Science TEKS Biology 2(A, C, D) Environmental Systems 2(A,C,D); 4(C); 5(A,B,F); 8(A,D) Aquatic Science 2(A,D,E); 3(B,D); 5(D); 8(A,B,C); 10(C)
Watershed - An an area of land that drains water into a particular creek, river, lake, or aquifer. Water drains downhill, so hills, ridges and other high points define the boundaries of a watershed.
Land Use - the human activity or economic function associated with a specific piece of land; the way the land is used in a watershed (e.g. residential, industrial).
Headwaters - the source of a creek or where the creek begins.
Mouth - the point where a creek enters a larger body of water.
Runoff - water that flows over the surface of the land into a creek, river, or lake; may carry a variety of pollutants.
Pervious Surface - a land surface such as grass or soil which allows water to filter through the ground.
Impervious Surface - a land surface such as a road, parking lot, sidewalk, rooftop, or other surface that does not allow water to filter through.
Point Source - a single identifiable source that discharges pollutants into the environment (e.g. sewer, ditch, pipe).
Non-point Source Pollution - pollution that cannot be traced to a single point because it comes from many individual sources or a widespread area.
