* Australian Drinking Water Guidelines - 2011 (ADWG).

NA - Not Applicable
NG - No Guideline Value

# Although we aim for 100% compliance, the ADWG recognises that occasional exceedances may occur. Where there are sufficient sample results from a 12 month period, the 95th percentile statistic should be used to determine performance against the guideline value. Any exceedance requires immediate investigation and corrective action as agreed with SA Health.

# Prior to calculating % compliance for health related chemicals individual results are rounded to the same number of significant figures as the guideline value in the ADWG (as prescribed in the ADWG and agreed with SA Health).
