The <br />compliance monitoring water samples are part of the amended permit requirement (Incas Mine <br />Amendment AM-002) for both surface and underground water. The 1998 compliance water samples <br />have the following sample identification: <br />location & number location 8 number <br />underground water surtace water date sample <br />year Adit 1 Lower Compliance taken <br />1998 98103001 98103002 Oct 30, 1998 <br />Water sample identification is by 8 digits of numbers.
