Questioning Results

Because all of the pH tests we gathered seemed very basic, we decided to take a test of the water inside Anderson Residence Hall at Whitman College, in Walla Walla very close to testing site 4.

We found the water there to have a pH of 6.
According to the test which we used, an ideal pH is between 5.5 and 6.5.
Because the water we tested in Anderson has been approved for our drinking, we have assumed that the pH of 6 is indeed correct.

Because we have deemed that the pH levels we tested of Mill Creek are indeed correct, we now are questioning why the creek is so basic. What different causes are there? This has pointed us in a new direction for our research.

Riley will continue doing research on the effects of stormwater pollution, while Marra will now be focusing on the specific sources in Walla Walla. Hopefully she will be able to find more information regarding why Mill Creek is so basic.
