"l'he lvater supplied to Capitol Whter's s)'stem cornes from deep wells. Some of the well rvater is treated with the addition of a small arnounl of food grade phosphate. The purpose of this action is to sequester some of the minerals that occur in some of our rvells. This effort should help in keeping our u'ater clear, Later in this report is a map shoning the boundaries of this u'ater system and the locations of the r,vel.ls serving this area. Ir.{ost all drinking w'ater (including bottled rvater) can contain small amounts of various contaminants. The presence of contaminates does not necessarily indicate a health risk.

This means present laboratory testing procedures cannot reasonabll,' detect some contaminants belorv certain Ievels. When a contaminant is listed as a non-detect (ND), it can mean trvo things: it is either non-present. or the present testing systern is incapable of detecting this malerial at this lo'*v level. Some people, becatse of certain t5,pes of health problerns. may be more susceptible to certain contaminants than the general populace. Immune-compromised persons such as persons rvith cancer undergoing chemotherapy! persons rvho have underyone organ transplants, people ,'vith IItViAids or other immune system disorders, sorne elderly, and infants can be panicularl."- at risk from inf'ections. These people should seek advice about drinking \&'ater from their health care providers.

MICROBIOLOGICAL Colitbrrn bacteria are naturally present in the environment found in the intestinal tract of bottr animals and humans. Colilbrrn bacteria alone are not pathogenic, Howevel their presence indicates that other disease causing bacteria rnay be present. Because of this, they are refbrred to as "indicator organisms". Tlvo specific types of coliform bacteria, which indicate that the rvater may be contan:inated with human or animal waste. are Fecal Coliform and Escherichia Coli (E. Coli). These bacteria can cause food-borne and water-borne outbreaks of intestinal discomfort. Capitol Yy'ater Corporation collects ten samples a month (120 per year) to comply with the Safe Drinking Water Act. If any of the tests shor.v fecal coliforrn,E. Coli are present, our customers must be notified. Occasionaily this does occur and a second test is performed, This second test nrost often is not positive and no notification is required. Our system was in compliance r.r'ith the M.C.L.'s established for this monitoring in 2014. TURBIDITY Turbidify- is a measurement relating to clarity of the water, General deep rvell \r$'ater is not aftected by the conditions lhat cause turbidit,v to occur. Capitol \later Corporation has not had any problems concerning this issue. CRYPTOSPORIDIUM Cryptosporidium is a parasite that can live in tlre intesrines of humans and animals and is most con::monhi found in st{face rvaters. Drinking '"vater w,ith this parasite present can cause an illness that produces symptoms of severe intestinal distress. No cryptosporidium has been found present in Capitol S/aler Corporation's water. p.4 O9j5:12 a.m. 07-02-2015 | 5 206 (x)51 Jul 02 15 03:40p Capitol Water Corp.208 375 0951 \VA]'ER SERVI C E I MPROVEN,TENTS 1. W'e are continuing the follou,ing program: A.S.R. (Aquif'er Storage Recovery) is a project that has enabled Capirol Water to maintain adequate rvater pressLrre durirrg the lrot nronths ol'July arrd August.

Most generally,9094 of the rrvater put into the uell can be extracted during higli demand usage. A.S.R. Project continues to help u'ith the high u,ater usage during the nrondrs of high demand (generally July and August). We are continuing this technique. 2. Very limle, if any, grorvth in the system willoccur during 2015. 3. We continue to replace 2" galvanized mains in 2015-. 4. We will continue injecting phosphate in the u,ater al most of our rvell sites. Where the rvater requires phosphate, the wells are equipped with proper injection equripmerrt to nreer the uecessar,v arnonnl of the sequestering additive. 5. We continue to upgrade our pumping equiprnent & electronics in an effion to provide adequate & consistent rvater pressLlre. WATER QLTALITY PROBLEPIS THAT OCCUR 1. Discolored waler. generally rusry colored, occasionally occurs and is usLrally caused b;.' hydrant flushing or a break in a uater main. An1.' sudden increase in flow rate will corrtribute to this annovance. To clear this conditiorr, it is best to wait about 30 minutes then run the cold rvater tap in the bathtub. Ifthisdoesn'tclearthervatercallCapitollrVaterat3T5-0931forfurtherinstructions. 2. listed belorv. Air in the rvater/milky n ater is a condition that could occur for several reasons and are A. Cold water that is elevated in tcmperature. This allor.vs dissolved oxygen to be released and the rvater becomes milky B. Overheating of hot 'rvater systems, generally hot rvater heater. C. \tater reacts wilh the zinc that is associated with galvanized pipe (generally nerv hornes). D. Cold ryater drarvn from the lrousehold tap, when tlre water is released from a pressure environment. the dissolved oxygen is released and causes the rtater to become rnilky. E. Air orrl.v cornes frorn tlre tap. Tlris is caused by the water table at a rvcll falling belorv the pump bou'ls. Hopefully this doesn't happen very often because it rvill ru[n the n'ell pump. If this happerrs, please callCapitol \\'ater at 375-0931 and [et us know t]ris is occurring at y'our residence or business so we can adjust the pump.
