<END_TASK>
<USER_TASK:>
Description:
 You can download water chemistry of an entire HUC.  It downloads wells and springs and major ions by default, unless specified otherwise.
Step1:  Standardize the headers and units in the results file.
<ASSISTANT_TASK:>
Python Code:
chem = wa.WQP(16020301,'huc')
Explanation: You can download water chemistry of an entire HUC.  It downloads wells and springs and major ions by default, unless specified otherwise.

pipr = wa.piper(Piv,var_col='TDS')
stream = wa.WQP(16020301,'huc',siteType='Stream',sampleMedia='Water',characteristicName='Specific conductance')
Explanation: Standardize the headers and units in the results file.
