The number of samples that drinking water systems are required to take is often perplexing to operators. At the risk of oversimplification, samples can be grouped into two camps - source and distribution.
Source samples are taken to determine what contaminants may be originating from the well or springs, etc.
Distribution samples, DBP and Lead/Copper, are taken to determine what may be happening to the water as it “ages” in the pipes, as it makes its way to your customers (Total Coliform (bacteria) samples are also distribution samples, and I’ll talk about these in a future tip).
Since the temperature of the water can play a role in what takes place, warmer water tending to make things worse, Disinfection-by-Products (DBP) and Lead/Copper samples must be taken during the time of year when the water tends to be the warmest - for us, the third quarter of the year. If you are required to take DBP samples (because you chlorinate your water), or it’s the year that you need to take Lead/Copper samples, then you have until the end of this month to git ‘er done.
If you are uncertain as to whether either of these are due this year, you can check your sampling monitoring report at waterlink.utah.gov
DUNCAN, Okla. – Staff from the Texas Rural Water Association and the Louisiana Rural Water Association have begun providing assistance to the small water and wastewater utilities affected by Hurricane Harvey. As flood waters recede, these water professionals are beginning to assess systems, provide emergency power generation and provide assistance with repairs.
TRWA has already provided generators for the Mauriceville Special Utility District, the City of Smiley, Cape Carancahua Water Supply Corporation, River Oaks WSC, Nueces County Water Control & Improvement District #4 and the City of Woodsboro. Texas Rural Water is providing hands-on assistance to 27 systems so far and has contacted over 200 more.
They also helped coordinate assistance between members through the Rural Water Emergency Assistance Cooperative.
“We received a lot of offers from non-impacted systems to provide man power and equipment to systems in need,” said TRWA Executive Director Lara Zent.
In one example, Jonah SUD sent personnel and equipment to assist Holiday Beach WSC with locating leaks, repairing lines and closing off meters to damaged structures.
LRWA Circuit Riders are helping locate and repair leaks caused by heavy rain and flooding.
“The systems in Southwest Louisiana have been constantly getting more rain,” said LRWA Executive Director Pat Credeur. “There is some flooding in the low-lying areas of Cameron, Vermillion and Calcasieu Parishes.”
Rural Water will provide updates as more information becomes available.
