Latest News

• Pre-assembled PRS Monitoring Stations Now Available. To save water utility personnel time and money, the Rundle-Spence Company of Wisconsin now assembles and ships PRS Monitoring Stations. In addition, the stations are more streamlined and less expensive than the earlier models. The Rundle-Spence Company is independent of Process Research Solutions. The PRS Monitoring Station design was published for all to use; Rundle-Spence is fullfilling a need that has arisen from interest in proactive distribution system water quality monitoring.
• Proactive Detection and Response are Key in Lead and Copper Rule Compliance. Lead and Copper Rule issues are tackled using PRS Monitoring Stations as described in the January 2011 issue of Opflow.
• Webcast on Proactive Detection and Response in Lead and Copper Rule Compliance. An American Water Works Association webcast was aired on January 26, 2011 on 'Distribution System Water Quality Concerns'. Results of the Process Research Solutions distribution system monitoring protocol were demonstrated as one of three presentations.
• Water Utility Monitoring Consortium and Tailored Collaboration Grant for 2012. We are beginning organization for leading a group of water utilities into routine distribution system monitoring for 2012. As additional resources for the project, a Water Research Foundation Tailored Collaboration grant will be applied for. If you are interested in joining the group please contact us at info@processresearch.net
• Water Utility Monitoring Consortium for 2011. The water utility consortium for 2011 distribution system monitoring is now underway.
• Corrections to Daily Reporter February 14, 2011 article. Process Research Solutions (PRS) appreciates the article on biofilms in buildings' plumbing systems which weighed heavily on work performed by PRS. However, there are some erroneous statements that people have been inquiring about. The corrections are as follows:
  • PRS did not identify the type of microorganism or microorganisms that caused the elevated copper in the Door County Justice Center. A previous consultant to Door County made an identification of one type of microorganism. PRS, instead, uses an indicator of microbiological activity. The test has some shortcomings but is the only inexpensive test available. The indicator has proved itself to be a good quantitative guide to biofilm issues in many PRS projects. In some past projects, PRS has worked with a microbiologist to identify the microbiological species involved. Sometimes, there are dominant players in a problem. However, overall, there are typically various types of microorganisms involved in a microbiological problem with different species living together symbiotically. No matter what, the answer is cleaning, disinfection, and monitoring.
  • The Brown Deer investigation into pinhole leaks in copper pipes took place in 2002 and 2003. The water provider to Brown Deer and their consultant did not agree that the problem was microbiological as reported in a Milwaukee Journal Sentinel June 12, 2006 article. Nevertheless, Brown Deer went with PRS' findings that it was a microbiological problem. The Village boosted disinfection and cleaned pipes with uni-directional flushing. The problem was resolved as indicated by lowered microbiological activity in the distribution system, cessation of pipe leaks, and greatly lowered unaccounted-for water loss. This was reported in an article in Materials Performance in June 2006.
