Corrective Action Plan to reduce the arsenic level in our water
The
following plan was put together with inputs from our water system operator.
We have developed
a two step plan moving forward. The goal is to reduce the As V levels in our
distribution system to comply with the current standards.
Our first
step is to replace our Manganese Dioxide greensand filter media. By replacing
the filter media, it is anticipated this will reduce the pentavalent arsenic
levels in the distribution system. BRMWC
has received a quote from Dougherty Pump for this job. The job entails removal
of the media from the existing tanks, cleaning of the tanks, install and
commissioning new manganese dioxide (NSF 61 approved) media and monitoring arsenic
levels post filtration. This effort should be completed by the end of June
2017.
The second
step will be to refurbish Well #2. This job will be completed by Dougherty
Pump. It is anticipated to have this completed around April 2018. The scope of
this job is the same as the refurbishing of Well #1.
As a side
note, last year BRMWC refurbished its 125,000 gal. water holding tank. (Dec
2015 – Nov 2016). BRMWC also had well #1 refurbished by having it brushed,
cleaned and test pumped. Pumping date is being provided. It also shows a low
reading of arsenic levels. The arsenic levels recorded from Well #1, since Sept
16, 2016, have not exceeded 10 ug/L.
If both
projects go as planned we hope to be in compliance by early 2018.
Thank you
for reviewing BRMWC corrective action plan and working with us to bring this
arsenic problem under control.
