r <br /> lead or iron rather. There were no hits at all. This year they did the testing <br /> ire-house with the lab personnel from grater pollution with Stearns <br /> Wheeler doing the actual write-up. What happened was that on six of the <br /> wells the iron was sky high It care down to the fact that they had to pay <br /> to re-sample. They sent one to Barnstable county and the ether to an <br /> independent lab. What happened was that they didn't have the right media <br /> filter. <br /> Mr. Farrington understood the process because he used to do it. They <br /> filter it in the field because they are looking for dissolved metals. <br /> Mr. Santos added that Mr. Huefelder at the county noted that some of the <br /> samples showed some floating solids and that was probably what the <br /> problem was, That was the only reason why he was asking. He stated that <br /> it was probably no big deal.. <br /> Mr. Harrington added that they were looking for the dissolve factor. When <br /> you test the drinking water you don't actually filter that because they <br /> want to know what the total exposure is for the individual. When they do <br /> the sampling in the field. You have to do a nitric acid wash in between the <br /> testing. You can contaminate all of your filter and everything, which is no <br /> fun because if you don't do it right nitric acid is very nasty acid to work <br /> with. That was what he used to do in the field. Nobody else in the <br /> company would do it. You can send your sample to the lab. They will filter <br /> it for you. But, they charge extra to do it. He was the only one who would <br /> do it for the company and filter it in the field. It was not that hard to'do as <br /> long as you have some decent protocol and get used to doing it. They <br /> were looking for dissolve faction but they were not filtering it. <br /> Mr. Santos agreed that they were not doing it right in the field. He wasn't <br /> trying to be a pain. He just wanted to ask a few questions. <br /> Ms. Grady noted that they don't say why the pH would be all off like that. <br /> Why would it be so acidic? <br /> Mr. Santos added that there could be a high acidic content in the natural <br /> soils sometimes. You could have therm low or high. It depended on the <br /> make up of the soil. It should be at 6.5 with y being a neutral. <br /> Ms. Grady noted that it was 5.77 and 6,28, <br /> Ms. Warden noted that the amount of iron could affect the pH. <br /> Mr. Harrington added that the acidity stripped the iron and the manganese <br /> off of the soil. That is why you get high amounts in the ground water. For <br /> 1 <br />
