dc.description.abstract	Nitrite (NO2) is usually found in a number of the very few less than on nitrate, because it is not stable with the presence of oxygen. Nitrite salts are used as inhibitors corrosion process in industry. Nitrite parameters were measured using the spectrophotometric Portable DR 2010, with a wavelength 507 nm. Measurement results expressed in mg/L. Nitrite levels obtained by range of 0,004 mg/L-0,011 mg/L. From the results of the analysis can be made that the nitrite levels in each well water meets standards Indonesian Government Regulation No. 20 of 1990, dated June 5 of 1990 on the control of water pollution.	en_US
