Lead and Copper Water Sample Results
The San Dieguito Water District is providing you with the lead and copper test results on the water sample collected at your location. Please share this notice with everyone who uses or drinks the water.
The results at: St. John’s Catholic School
Lead 0.56 ug/L and Copper 640 ug/L.
The maximum contaminant level goal (MCLG) is the level of a contaminant in drinking water below which there are no known or expected risks to health. MCLGs allow for a margin of safety. The regulatory limits for lead and copper are called action levels. An exceedance occurs when the concentration of the lead or copper in more than 10 percent of the tap water samples exceeds an action level.
- The MCLG for lead is “0” and the action level is 15 ug/L (or .015 mg/L).
- The MCLG and action level for copper is 1,300 ug/L (or 1.3 mg/L).
Lead or copper action level exceedances will trigger corrosion control treatment or other requirements. We will notify all water users if our system exceeds the lead action level. For more information regarding lead and copper visit ww w.e 1a.0 ov/safewater/1ead or
