Nitrate (N03l level of drinking and irrigation water sources in AI-Qassim Region-Central Saudi Arabia was Investigated. The obtained analytical results indicate that there is a considerable variation in NOl' level between the municipal network water supply and domestically produced bottled water on one hand and well water on the other hand. The mean of NO; level of the latter (69.7mgL·') is above the maximum permissible level (45 mg L") set by the local and international standards and guidelines. Of the 40 well water samples examined only 23 (57%) comply with the guidelines set for the maximum permissible level set by most of the standards. Statistical analysis (Correlation) revealed a Significant reciprocal relationship between depth of well and NOli- level (P< .01, R2=0.293).
