JUN 13 '96 02:39PM SJ_1 :OMMUNITY-DEV. P.4/6 <br /> in environmental microbiology I am concern far the lona term publ_:c <br /> health effects horses or other large domestic animals cou'.d have car. <br /> dr inking water systems in this area. My area of expertise covers <br /> groundwaters and in fact' am the developer of laboratory and =ie_d <br /> methods used by California and other states to determine wh cr_ <br /> ground .gat-ars are under the direct influence of sur=ace grater arid <br /> t heratore subject to contamination by the mir_roorganisms mentioned <br /> above. We are now convinced that man and his domesticated animals <br /> are more closely linked in the spread of disease then ever before, <br /> Dartic .zIarly with regard to protozoan parasite such Giardia and <br /> 'rvntasNordium (GIC) and certain gastrointestinal bacteria such as <br /> F. co=i 057 :K7. New emerging protozoans par.asit3s sucl as <br /> c-, ^Zostoria and Micresmoridium my also be carried by dorrastic <br /> animals and possess the same potential to be spread by t;ie watez <br /> routs. Protozoans parasites such as G/C survive in the envircrimerr.t <br /> including ground waters) for longer periods of time. The;,;, are <br /> protected from environmentalt <br /> assaults by the cysts and oocysthey <br /> produce dur::ng fecal. excretion. The oocysts of Cr"tosnordium and <br /> ?re known the be totally resistant to chemical disinfection <br /> including all fortis of chlorination. As an example, the surf ace <br /> water used by the city cf Tracy (Delta Mendota Canal) rear the <br /> airport (5 miles west of this parcel) is grossly contaminated with <br /> these parasites and is known in California as one cf -he -.gorse <br /> source -water drinking water sites in the state. Extensi a <br /> incluc ing ccriventional filtration and chlorination 'is requircad t, <br /> the S=ate to deal with this type of contamination Even :with this <br /> treatment, I art certain that Crvtitosoordium oocysts will be found <br /> in the f_nisned water once the national EPA Information Ccllect_cr <br /> :ule (_CR) requires the monitoring in of this and ether, organlzin In <br /> surfaca water and ground water under the influence of suriaca <br /> wa tar. This mcnitcring will start early next year and will cost <br /> ;;a-er ,;tiI-4ties and the nation $+60, 000 , 00G . At the present <br /> the ZCR is the number one priority at EPA and is prcceeding aheaJ <br /> in spit=_ of major budget reductions . <br /> In conclusion, I feel that the paszurj.ng of horsy or <br /> large animals :mown to be irfacted with parasites or bacterimL mL <br /> infactious to humans should be prohibited or at lease :rjitygated tD <br /> insure -hat i_r igatior. water is retained with?n the con:°ines of tha <br /> property away from any well water source.
