AdEdge’s
treatment technology has been installed in a number of unique applications and
locations. In February 2012, AdEdge was contacted to help
remove arsenic and manganese from the drinking water supply of a rural
community in New Mexico.
The San Antonio Mutual Domestic Water Consumers Association
(MDWCA) is one of approximately 200 such organizations around the state of New
Mexico. Elevated arsenic and manganese levels in this system, which serves 855
residents and handles 80,000 gallons per day, led operators to contact AdEdge
for a treatment solution. Before AdEdge stepped in, the MDWCA was experiencing
an arsenic level of 0.014 mg/L and a manganese level of 1.10 mg/L—well above
the EPA’s maximum contaminant levels of 0.010 mg/L and 0.05 mg/L, respectively.
New Mexico is no stranger to water quality concerns. The
Sanitary Projects Act was passed in the state in 1947 as a response to a public
health crisis. Dangerous water practices were occurring, primarily in rural
areas, with citizens obtaining drinking water from sources that were often
unsanitary, such as ditches and shallow wells.
In an effort to deliver safe drinking water to these
communities, the Sanitary Projects Act authorized and encouraged the creation
of MDWCAs, which have the authority to construct and operate water facilities
around the state.
At the San Antonio facility, AdEdge installed a 150
gallons-per-minute APU26
skid-mounted system consisting of three, 42-in. diameter vessels with a
multiple media filter. The treatment system includes chlorine and ferric
chloride chemical feed modules, with ADGS+
coagulation/filtration media with an anthracite cap to remove the
contaminants. The media is all ANSI/NSF 61-certified by the Water Quality
Association. AdEdge’s H2Zero Backwash Recycle system then treats and manages
the contaminated backwash water.
The San Antonio system was started up in June 2012 and has successfully reduced the
arsenic and manganese levels well below the EPA’s maximum contaminant levels.
