,A water system is required to conduct quarterly monitoring less
frequently than quarterly under the Stage 2 Disinfection By-products
Requirements they must begin monitoring in the calendar month -
ANSWERS-Recommended in the Initial Distribution System
Evaluation (IDSE) report
A water system that is required to sample quarterly must make
compliance calculations at the end of? - ANSWERS-The fourth
quarter

How are samples for lead and copper analyses collected from services
that have a lead service line? - ANSWERS-First flush the volume of
water between tap and lead service line, then collect the sample
When can a water system that meets the lead and copper action levels
for two consecutive six-month periods, reduce the number of samples
and reduce the frequency of sampling at the same time such that they
, only sample every 3 years? - ANSWERS-When the 90th percentiles
for lead and copper are 0.005 mg/L and 0.65 mg/L, respectively

reduction in the number and frequency of sampling, unless the State
has approved a different sampling period, shall conduct lead and
copper sampling during which months? - ANSWERS-June, July,
August, and September
A small water system has met certain criteria and has been granted a
waiver and thus a reduced frequency for monitoring lead and copper.
How often with this waiver does it have to monitor? - ANSWERS-
Once every 9 years

because it exceeded the lead and copper action level, what parameter
must be measured every two weeks at each entry point to the
distribution system? - ANSWERS-pH
Each day following a routine sample monitoring result that exceeds
the maximum residual disenfectant level for chlorine dioxide, the
water system must collect from the distribution system how many
samples for analyses of chlorine dioxide? - ANSWERS-3
