To the Editor,

Each year by July 1, water authorities must provide customers with a Consumer Confidence Report on the quality of water they produced for the previous year.

These are required by the Federal EPA. EPA standards must be met for water quality and if they don’t, they must give you detail about the contaminant.

I studied the report from the South Granville Water & Sewer Authority and wondered why a class of water contaminants was missing from it. Microscopic water pathogens which include parasites, bacteria and viruses were missing. Some of them are parasites like one called cryptosporidium, a microscopic creature that causes gastrointestinal illness (diarrhea, vomiting, cramps).

EPA believes that there is “sufficient information to conclude that cryptosporidium may pose a risk to human health.” SGWASA detected this cryptosporidium in our “finished water” but failed to report it on the annual report.

I contacted the state Department of Environmental Quality and asked them if SGWASA should have reported on this parasite. DEQ emailed me back that SGWASA should have reported the detection of cryptosporidium in the CCR. They have contacted SGWASA and advised them to revise the 2018 CCR so that it contains that information.

I have looked at the Kerr Lake Regional Water System Customer Confidence Report for 2018 and it indicates four EPA violations for water quality for that period. They already have two more violations for this year; one for each quarter. People in Oxford have received notices about that. In their report, Kerr Lake Regional System also indicates they are concerned about cryptosporidium and they “encourage immunocompromised individuals to consult their doctor regarding appropriate precautions to take to avoid infection.” That seems to indicate they have that parasite in their “finished” water also. I mention Kerr Lake System to indicate general water concerns in Granville County.

You might also like to see the list of EPA contaminants that they regulate where you can see the water pathogens listed in pink color. This list might also help you understand the SGWASA 2018 water quality report. That can be seen at:
