Cross-Connection Control: Public Notification

  • Backflow of herbicide into Mississippi system results in "do not drink" warning (Clarksdale Press Register, April 6) which was later changed by the state to a boil water alert?
    Commentary: The back story of this incident is illustrative: A farmer drops the end of a water hose into a herbicide mixing tank at the same time as a pressure drop in the system siphoning Roundup into the system. The "do not drink" notice went out until flushing was complete, then the "boil water" notice was issued to cover uncertainty until the bacti results all come back clean.

Water Treatment Residuals: From Troublesome Sludge to Desirable Commodity

 McGuire Malcolm Pirnie Environmental Consultants offers specialty services to assist utilities in managing water treatment residuals (WTRs). We can assist utilities with recycle audits, Filter Backwash Recycle Rule (FBRR) compliance, arsenic residuals management, selection of innovative dewatering methods, and optimization of existing WTR facilities. Most importantly, we can help utilities determine the unique chemical and physical characteristics of their WTR, evaluate and recommend options, and establish a viable beneficial use program.

For more information on these services, please contact Jim DeWolfe at jdewolfe@pirnie.com or visit mcguireinc.com/wtr. Mr. DeWolfe was honored with the Ivan M. Glace Award by The Water Works Operators’ Association of Pennsylvania (WWOAP).

 

Lead

  • Report: Durham, NC, lead tests done in good faith (Durham Herald Sun, April 6)
    Commentary: Almost buried in the discussion of an outside review panel's report on Durham's lead testing was the news that the city thinks they know what caused the increase in lead levels. "...Water Management Director Terry Rolan said that when his plant operators started using the chlorine/ammonia mix, they also boosted the alkalinity of the city's water in line with industry practice to keep ... from causing taste and odor problems. They assumed that the increased alkalinity would, if anything, help prevent lead from leaching out of household plumbing... But after a child ... came down with lead poisoning last spring, they ... found an EPA report that warned higher alkalinity could reduce -- by half -- the effectiveness of the chemical Durham uses to minimize pipe corrosion. 'None of us recognized the problem until we started looking, digging into the problem,' Rolan said, adding that once officials read the EPA report, plant operators lowered the water's alkalinity slightly and tripled the amount of corrosion inhibitor they use."
  • Canadian city says "standing water test" for lead is not the standard (Prince Albert Daily Herald, April 5)
  • Elevated lead levels found in 9 of 56 samples collected at North Carolina school (Winston-Salem Journal, April 7)
