A

water treatment plant relies on
the abilities of many individuals to take on various roles to
ensure the production of safe
drinking water. These roles cover a variety
of responsibilities and some of them may
involve the monitoring of continuously
collected sampling data, analysis and data
interpretation.
Water treatment plants in Ontario must
routinely sample and test for numerous
microbiological, chemical, and radiological parameters as mandated by the
Safe Drinking Water Act through Ontario
Regulations 170/03 and 169/03. Turbidity,
pH, and chlorine residuals must also be
monitored. Operating authorities can
send these samples to contracted, certified labs or they can choose to set up and
certify in-house labs to perform their own
tests. To meet regulatory requirements
as well as optimize plant performance,
facilities must work towards the development of well-structured programs
with standard operating procedures and
training in an effort to continuously seek
improvement. A good quality assurance
and quality control program is defined
by scientifically sound, legally defensible
data of known and documented quality standards. The effectiveness of the
12 | O N T A R I O P I P E L I N E | FALL 2018

program will rely on clearly defined objectives, well documented procedures and
support and buy-in from operational staff
and management.
So, what is quality assurance? It is continuously monitoring the reliability of
results and the control of quality through
the use of good equipment, analytical
grade reagents, and standard operating
procedures.
What is quality control? This is broken
down into two steps: 1) the accuracy, which
is the degree of difference between an
observed or tested value vs. the known
value of the standard; and 2) the precision, which is the ability to consistently
reproduce similar measurements under
the same conditions (one sample analyzed
more than once achieving the same or similar result).
A well-developed quality control and
quality assurance program will support the
production of good data. Good data and
good data interpretation support good
process control decisions. Inadequate or
poor quality data leading to poor process
control decisions can lead to adverse water
conditions, non-compliance orders, and
low team morale.
One key component of the QA/QC program is the development and maintenance

of standard operating procedures (SOPs).
To this end, an organization compiles a
detailed, step-by-step set of instructions
for handling daily complex operations. The
goal of these procedures is to help maintain
a level of performance that is both uniform
and efficient, while at the same time minimizing the potential for miscommunication
or non-compliance with industry guidelines and regulations. Normally, in any facility you don't always identify the need for
an SOP until you are faced with a new challenge, or an incident has occurred and part
of the corrective action is the creation of a
new SOP. It is always best to be proactive
and develop an SOP prior to an incident to
avoid unnecessary failure or system upset.
It is encouraged as part of this program to
start with an SOP that provides direction
to support the structure of the program i.e.
what is expected of staff, and what task by
task steps are required.
To support the creation of a new SOP, it
is always important to get input and commitment from all staff, as the individual
developing the SOP may not have all the
required details to make it successful. Staff
involvement will also support buy in. Once
an SOP is developed, one or more staff
should be identified to make sure that all
the components are well communicated.
