One way to fix this problem is to install heavy duty septic tanks, connect washing machines to the tank, install a pipeline from the resident's septic tank to a holding tank, or connect it to Austin's city sewage. Drain fields need to be put in, and pesticides and herbicides should be restricted to help preserve Westcave. Livestock One major threat to the quality of water in the Westcave watershed is livestock contamination from cattle ranching. This is not only a problem at Westcave. If there is more demand for cattle, then there will also be more manure.
Manure washes into watersheds after heavy rainfall.
This can be a problem at Westcave since there is cattle ranching in the area. We could designate more land for cattle so there won't be too many head of cattle in one place. If we do this, it will be a small first step in keeping the whole world's water clean. If we all do a little, it will help a lot. When you raise animals in a small area, the manure builds up, and it runs off into lakes and rivers.
