New RCAP Videos on Distribution System Water Quality, Hydrants, and Chlorine Residual

New RCAP Videos on Distribution System Water Quality, Hydrants, and Chlorine Residual

I am delighted to share with you three new RCAP videos on drinking water operations best practices for maintaining compliance and protecting public health.  Please see descriptions below. These videos were produced through our EPA NPA1 regulatory compliance cooperative agreement.

In a couple weeks, we’ll distribute the two remaining videos in this series, which address coliform sampling and valve exercising and maintenance.

Please let me know if you have any questions.

Best regards,

Joy

Protecting Distribution System Water Quality https://vimeo.com/134849908

Just because you produced high quality water at the treatment facility doesn’t mean that your job is done. Maintaining water quality throughout your distribution system is also essential. Studies have shown that over 1/3 of waterborne illness originated from problems in the distribution system. Water quality in the distribution system can degrade for a variety of reasons including contamination from an uncontrolled cross connection, contamination during storage, or high water age leading to degradation of water quality. Events such as a main break or loss of system pressure can also allow contaminated water to enter the distribution system.

 

So as an operator what should you do? This video will discuss 6 items for you to consider to protect water quality in the distribution system. For more information about distribution system water quality and other topics, visit our website at www.rcap.org.

 

Hydrant Inspection and Flushing https://vimeo.com/134771413

This video will cover basic inspection and flushing of a fire hydrant. All fire hydrants in a water system need to be inspected on a regular basis. Inspection is needed to ensure a high degree of confidence that hydrants will perform properly in an emergency. A number of circumstances can affect a hydrant’s performance, including vandalism, accidental damage, wear and tear, and mechanical malfunction. Hydrants may also be flushed periodically to improve water quality. For more information about hydrant inspection and other topics, visit our website at rcap.org.

 

Measurement of Chlorine Residual – https://vimeo.com/134882448 

This video will cover taking a good chlorine sample and methods for analysis. Effective measurement of chlorine residual is essential for protection of public health. The presence of the residual not only provides disinfection, it also serves and an indicator of water quality. Loss of residual can be an indicator of a water quality problem.

 

Chlorine residual may be measured for compliance or non-compliance purposes. While the analysis will remain the same, how you collect the sample may differ. This video will discuss measurement of chlorine residual using a colorimeter and a handheld spectrophotometer.
