A. Yes, it would, because in some cases I was involved, we were talking about wellwater. And in some of these wells they have not used chlorine and they have failed.90. Q. Okay. So the existence of chlorine is a factor which affects the speed ofthe process?A. That is correct.91. Q. And then, assuming there is chlorine, the level of chlorine is a factor thatwould affect the speed of the process?A. That is correct.92. Q. And the existence and level of various minerals would affect the speedof the process?A. Some minerals, yes.93. Q. And just out of curiosity, could you give me two or three?A. Minerals? The more common ones you find in potable water is iron and you findsometimes copper, but even the titanium, which is used as a pigment, can be anotherfactor. There are a number of metals that will, basically, accelerate the degradationprocess.94. Q. Okay. And I take it that whether the water circulating is hot water or coldwater affects the speed of the process?A. The circulation certainly would, hot water certainly would, because temperatureis a factor in the acceleration of these reactions.

95. Q. Right. So, typically, houses are divided into hot and cold water lines.A. Yes, of course.96. Q. So that will matter in terms of which one is likely to go first?A. That is correct.97. Q. And then, within either, I guess, the relative temperature of the cold andhot water ... in other words, there is hot and hotter ... the temperature atwhich any given house runs its hot water will have an effect on the process?A. An increase of temperature always will have an effect of speeding the reaction.98. Q. All right. The stress to which the pipe has been subjected, I take it, willbe another factor?A. That is another factor that does accelerate degradation, yes.99. Q. And in these systems, stress can come, for example, from the degree towhich the pipe is bent?A. Yes.100. Q. And stress can come, for example, by the degree to which the pipe andfittings are crimped together. That is another form of stress within ...A. That is a form of stress, yes.
