The analytical laboratory places a total of 2 ml of nitric acid-in some of the 1 liter bottles to reduce the pH to below 2. On an annual basis an extra preserved bottle will be, filled with .groundwater and-the pH measured lir the bottle.. It is ed that the pH will be-below 2: If it is not the field technician will add nitric acid in measured amounts until the pH,is below 2. This added quantity of acid will be placed in all the preserved botdcs-duzing the folio rounds until it is checked airy the fbHo ear:S Ie� � monitoring again "Y. anxP FH" - _canfirnied.:at.the•.: laboratory and recorded.

For *eUs withdb t dedicated pumps, the samples=' =nsfcrxcd from the barer,through a f&cr apperatus, into the ropriate e . The filter#Vxatus consists of a PrCSSM vessel,a ed - pressutm pump, and a fitter cartridge. Water frgm the bailer is Placed in the pressum vessel snd enough air pressure(via the hand pmmp)is applied to force water through the filter cartridge into the sample bottles. The pre== vessel is washed in Alconox, steam cleaned, and rinsedwith deicni=d water between wells_ A new fihw cartridge is used at each well. Simples will. be ed with a unique sample identification number, project i cation number?sample location,and date and time sampled. Samples will be transported to the contract laboratory under strict chain-of-custody procedures.. 83849-F41L2314R325 A-9 July 14,2044 2000 Kkbt d*r'rte.
