| Details: | Left a voice mail about 5 follow up samples for spring source and posted the following via us mail: RE: E. coli at Anderson Mountain Spring (pws 05549) Lisa Cornell: A sample taken on 12/13/22 at the spring source of Anderson Mountain Springs showed the presence of E coli. My primary hope in this communication is that you can give fellow consumers a sense of the risk that the presence of E. coli represents. Of secondary interest is outlining the follow-up rules triggered by the E. coli that was found. Risk Communication Interest: E. coli is a bacterial organism associated with fecal contamination often found in surface water. Chlorine disinfection can make a water source free of bacteria, but with surface water also comes risk of parasitic and viral pathogens. Lab analysis for coliform sample showing no coliform present is not indicative of the presence of parasitic and viral organisms. After the 12/13/22 sample showing E coli present makes now a good time to communicate or recommunicate the risk of other pathogenic organisms to households using Anderson Mountain Springs water. Enclosed is a template boil notice. You may find some language in the document helpful for a written communication. What the Rule says in Brevity: The rule says if E. coli is found in a pre-treatment source sample to follow-up with 5 additional source samples within the next ten days. If each of those 5 samples are clean of E. coli you would return to the quarterly scheduled routine coliform sampling. If any of those samples shows E. coli present it means in a timely way: (1) Working with someone representing state Drinking Water Services to make a site visit to the spring and direct correction of any hazards found; or (2) Providing 4-log viral disinfection; or (3) Finding a new [safer] water source; and (5) Providing legal risk communication to households using the water. Call 541-266-6720 to discuss (1) effective risk communication or (2) understanding ter |
