The sample was <br /> reanalyzed after a compliant standard, however the ending check was outside the <br /> limit (high) . Since similar results were observed, the first analysis is <br /> reported. <br /> 06913 TPH-DRO(C10-C25)Water w/ SiGel n.a. 91 50 ug/l 1 <br /> The observed sample pattern includes #2 fuel/diesel and an additional <br /> pattern which elutes later in the DRO range. <br /> 01750 Calcium 7440-70-2 92,900. 70.2 ug/l 1 <br /> 01754 Iron 7439-89-6 606. 52.2 ug/l 1 <br /> 01757 Magnesium 7439-95-4 43,800. 13.5 ug/l 1 <br /> 01762 Potassium 7440-09-7 753. 50.3 ug/l 1 <br /> 01767 Sodium 7440-23-5 114,000. 2,170. ug/l 5 <br /> 06256 Total Hardness as CaCO3 411-34-1 412,000 200 ug/l 1 <br /> 07058 Manganese 7439-96-5 244. 0.84 ug/l 1 <br /> 08014 Boron 7440-42-8 1,070. 9.4 ug/l 1 <br /> 00201 Alkalinity to pH 8.3 n.a.
