There are very few laboratories capable <br /> of performing such tests and costs of such tests are high. The follow- <br /> ing are two testing laboratories capable of performing such tests: <br /> 1. Wahler & Associates <br /> P. 0. Box 10023 <br /> 1023 Corporation Way <br /> Palo Alto , CA 94303 <br /> Mr. Richard Volpe - 415/968-6250 <br /> 2. Terra-Tek <br /> 420 Wakara Way <br /> Salt Lake City, UT 84108 <br /> Mr. Scott Butters - 801/582-2220 <br />
