Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer undergoing chemotherapy, p".ion, who haue undergone organtransplants, people with HIV/AIDS or other immune system disorders, some eiderly, and infants can bJparticularlyat risk from infections. These people should seek advice about drinking water frorntheir health .u.. p.orid..r.EPA/Centers for Disease Control (CDC) guidelines on appropriate means to lessen the risk of infection byCryptosporidium and other microbial contaminants are available from the Safe Water Drinking Hotline(800-426-4791).

Drinking water' including bottled water, may reasonably be expected to contain at least small amounts of somecontaminants. The presence of contaminates does not necessaiily indicate that water poses a health risk.

On source 235 l0l0-004 GPW there were 3 HIGHS: (1) the source is within 1,000 feet of highway and (2) the agricultural land coverover the aquifer is over l\oh and, (3) there are l0 or more septic systems and/tr any'sewer lines within 500 ft. of thewell head protection area (WHPA) or there is a high density of septic systems (more than 30) in the WHpA. Wealso had one moderate ranking for each well that indicates there is at least I registered pesticide applicator in theWHPA but not within 500 Ft. of wellheads. All other assessments were considered LOw.

I [it' rttlu'ter lrf.tll'iul"itrq tl atcl- (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs,springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presenceof animals or from human activity. Contaminants that may be present in source water include:\licrohilrl e qlnt:lniirtan{r, such as viruses and bacteria, which may come from sewage treatment plants, septicsystems, agricultural livestock operations, and wildlife.Ittltrgltnic ciutirtiuirulnts, Such as salts and metals, which can be naturally occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining or farmingllerticitles :ttttl lte n"bie itles, which may come from a variety of sources such as agriculture, urban storm waterrunoff, and residential uses.{}rg:trlic cittrlliic:li eontitiltirlants, including synthetic and volatile organic chemicals, which are by-products of industrialprocesses and petroleum production, and can also come from gas stations, urban storm water runoff, and septic systems.I{ntlioactir c c,utttrtnlitt;trtts, which can be naturally-occurring or be the result of oil and gas production and miningactivities.Itt ol'tict'{lr cr:sute iit.lt t:rp lrater is vlfir tqr rll'iuli, EPAprescribesregulations which limitthe amountof certaincontaminants in water provided by public water systems. The US Food and Drug Administration (FDA) regulationsestablish limits for contaminants in bottled u ater u'hich must provide the same protection for public health.Radon: Radon is a radioactive gas that you can't see, taste or smell. It can move up through the ground and into a homethrough cracks and holes in the foundation. Radon can also get into indoor air when released from tap water fromshowering, washing dishes, and other household activities. It is a known human carcinogen. Breathing radon can lead tolung cancer. Drinking water containing radon may cause an increased risk of stomach cancer. Presently the EPA isreviewing a standard for radon in water.tr.cirtl: If present, elevated levels of lead can cause serious health problems, especially for pregnant women and youngchildren. Lead in drinking water is primarily from materials and components associated with service lines and homeplumbing. This water system is responsible for high quality drinking water, but cannot control the variety of materials usedin your plumbing components. When your water has been sitting for several hours, you can minimize the potential for leadexposure by flushing cold water from your tap for at least 30 seconds before using water for drinking or cooking. Do not usehot water for drinking and cooking. If you are concerned about lead in your water, you may wish to have your water tested.Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from theSafe Drinking Water Hotline or at http://www.epa.gov/drink/info/lead/index.cfm.

Water Quality ffiata TableThe table belorv lists all of the drinking water contaminants that we detected during the calendar year of this report. Thepresence of contaminants in the rvater does not necessarily indicate that the water poses a health risk. Unless otherwise noted,the data presented in this table is from testing done in the calendar year of the report. The EPA or the State requires us tomonitor for certain contaminants less than once per year because the concentrations of these contaminants do not changefrequently.

Please note that the New Hampshire Department of Environmental Services has issued the Tilton-Northfield Water District waivers for testing onSynthetic Organic Contaminants (SOCs) for 2012.

2012 was another very busy year of more improvements and upgrades. We replaced the Granite Street rivercrossing by directional drilling under the river with a new 12' water main improving fire flows throughout the system.This project continued with the replacement of the aging 6'main with a new 12' main all the way up Granite Streetto Summer Street in Northfield. ln cooperation with NHDOT and the Town of Northfield's project to replace theroadway, we also replaced an older 2" main with a new 6" main up Bean Hill Road for 520', ending with a newhydrant. ln another joint effort we replaced 300'of 2" walet main on Birch Drive in Tilton while Tilton Sewer wasreplacing their main. We have repaired many of our 2" main lines this year where leaks were discovered on CofranAve., School St., Arch St., Vine St., Howard Ave., and Cedar St. Every repair strengthens the system, reduceswasted water and maintains better service to our users.

As a continued part of our maintenance plan we flush all hydrants within the system twice annually to help maintainwater quality and ensure proper hydrant operation. We also completed the plans to install a SCADA (supervisorycontrol and data acquisition) System. lnstallation was completed in January of 2013. This system allows constanton line monitoring ol all our important infrastructure throughout the entire system to improve our ability to provideyour water supply with minimal interruptions and to maintain the highest water quality and fire flows possible. lnNovember we did a process called .lce Pigging' at the Route #140 well site. lt is a new technology which entailscreating an ice slurry, injecting it into a fire hydrant, and turning on the downstream water to push the slurry thru themain which scours the inside of the water main removing mineral scale from the inside of the pipe and is releasedout of a upstream hydrant. This is the latest technology in removing any buildup in a water main in a cost effectiveand environmentally friendly manner and was very successful.

We have also continued with replacing some aging equipment needed for working on repairing the system. Thisyear we replaced our tow behind air compressor, jack hammer, and our small asphalt paving roller we use for watermain break patches as planned for in our budget for equipment replacement reserve. We have made improvementsat our facility at 14 Academy Street, siding the barn and extending a carport at the end to protect the backhoe fromthe weather.

We have hired a new employee, Matthew Garcia. Matt is a licensed plumber and is currently studying to obtain hisWater Operator and Distribution license. We would like to take this opportunity to welcome Matt to the WaterDistrict. We are looking forward to a long and successful relationship.

As always, our goal - first and foremost - is water quality for the District users. We encourage you to attend ourmeetings; we thank you for your support and look forward to working for you.
