Coliform Contamination Source Found!

Short Story?  Prudence Island’s water problems come directly from the wells.

On August 27, 2019, and September 24, 2019 Indian Spring Well #4 was tested and coliform was present.  On September 24, 2019, coliform was also present in the Army Camp well.

As always, the official state records can be found at: https://dwq.health.ri.gov:8443/DWW/

But the most interesting information is in the screen shot below:

When coliform is detected in the water, a “Level 2 Assessment” must be performed to attempt to identify the source of the contamination.  This time, video from the Indian Spring well taken in 2013 was reviewed, and finally the defect was identified.  This means that coliform from Indian Spring well #4 could be the explanation for many of the contamination problems over the last several years. (The full L2 report is available, but see the image below for the relevant excerpt.)

It also means that the boil water order will probably have to extend until the well defects are corrected, or treatment is installed.  (And while the likely Indian Spring defect has been identified, the presence of coliform in Army Camp well remains a mystery… stay tuned for the next L2A…)

  1. I’m not a water professional but speak from homeowner experience. Drilled a well for a new house. Driller called to say he had good news and bad. Good news I have 36 gal per minute. Bad news: it’s full of iron and manganese. But we can filter it out. I installed a reverse osmosis and it back flushed once a day. They drain the tanks once a year and you should see the crap they dump out. I feel
    Filtration is the route to take with big blue.

    1. Would you be willing to share which neighborhood this is in (I’m guessing just south of the ferry dock)? The PIWD has some interest in developing a new well in hopes that treating the water from a new source would be cheaper than removing the iron and manganese from the Indian Springs wells. If they drill a new well, and it either doesn’t produce enough water, or produces water that is also high in iron, we’re right back where we started, so it would be best to avoid your area.

      Thanks!
