MUM has several dozen water filter systems around campus. See the lists below.

The University maintains three types of water filter system on campus: 6-stage reverse osmosis (RO) machines, 2-stage whole house filter systems, and 1-stage systems.

• A 1 stage system has a single filter, which reduces chlorine taste and odor, particles larger than 0.5 micron, and lime scale.
• A 2-stage system has two filters, which eliminate sediment, MTBE (a gasoline additive often found in groundwater), VOCs (volatile organic compounds), lead, cysts, and most chlorine.
• The 6-stages of the RO machines include the following: (1) activated carbon filter, (2) micron filter, (3) first ultraviolet light, (4) reverse osmosis, (5) post carbon filter, and (6) second ultraviolet light. These systems remove almost all chlorine, arsenic, fluoride, nitrate, sulfate, sodium, lead, other metals, and total dissolved solids (TDS), and they reduce soluble organic compounds (SOCs), including pesticides; dioxins; and volatile organic compounds (VOCs), including chloroform and petrochemicals.

Here are some detailed specs on the pre-filters and carbon filters we use on campus. These come from http://www.filtersfast.com.

The Culligan CW-F string wound polypropylene whole house filter is designed to reduce extra fine sand, dirt, silt, rust, and scale particles.

• 10 Micron Rating
• Reduces sand, rust, sediment, silt, dirt and scale particles
• Flow rate: 10 GPM @ < 1 psi
• Temp Range: 40 - 165 F

The Pentek CBR2-10 Under Sink Carbon Filter with lead-reduction media filters lead, VOC's, extra-fine sediment, bad taste & odor, and chlorine taste & odor from your drinking water.

• .5 Micron Rating
• Temp Range: 40 - 165 F
• Flow Rate: 0.5 - 1 GPM
• NSF Standard 42 Test and Certified
• Removes chlorine taste & odor, cysts, lead, VOC, MTBE and extra fine sediment
• Removes 99.95% of Cryptosporidium and Giardia Cysts

Dining hall cooking water goes through a special 3-stage system that eliminates more chlorine than a 2-stage system.

We monitor the water filter systems on campus and change the filters when needed according to taste. Below is a list of campus water filter stations:

6-stage systems that include reverse osmosis (RO)

• Argiro: northeast corner of cafe--student use only
• Golden Dome Market: planned

Everybody's has several 6-stage RO machines and charges 19 cents per gallon for water from these machines. For those who wish to add minerals to RO water, Everybody's carries ConcenTrace Trace Mineral Drops, which can remineralize water for about 10 cents a gallon.

Slow flow 2-stage systems (best type of on-campus system)

• Hirises: sink in basement laundry room
• Frats 106, 109, 110, 111, 112, 150: sink next to basement laundry area
• Vastu dorms: kitchen sink
• Hildenbrand
  • sink in south wing laundry room on middle floor
  • sink in south wing laundry room on upper floor
  • sink in north wing laundry room
  • sink in north wing basement bathroom basement kitchen sink
  • sink in south wing basement kitchen
• Henn Mansion: kitchen sink
• Headley Hall: kitchen sink

Fast flow 2-stage systems (not as good as slow flow 2-stage but better than 1-stage)

  • hot water dispenser in south dining hall northeast corner
  • cold and hot water dispensers in north dining hall
• Mens Dome: drinking fountain
• Ladies Dome: drinking fountain

The 1-stage and 2-stage water filter systems on this page are maintained by MUM Facilities Management. The RO machine in the Argiro cafe is maintained by an outside company under contract to Student Government. The RO machine in the Golden Dome Market is maintained by an outside company under contract to MUM.
