Federal regulations require Paradise Irrigation District to sample for lead and copper in your drinking water every three years and then the state reviews those samples for compliance. Based on the sampling results, there is no rea-son for concern. The samples show no lead and only minimal results for copper—and those levels are well below the action level for con-cern. However, if you are concerned about lead and/or copper in your water, you may wish to have your water tested. Information on lead and copper in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or a Quick Reference Guide at https://nepis.epa.gov/Exe/ZyPDF.cgi?Dockey=60001N8P.txt or call the district at 530/877-4971.
New regulations require the district to test for lead in the drinking water at all Paradise public schools or if requested.

 Chemical Year Sampled Violation Action Level Public Health Goal* Amount Detected at the 90th% Schools requesting sampling Sites Above Action Level
 Copper (ppm) 2017 No 1.3 0.3 0.01 0 0 of 30
 Lead (ppb) 2017 No 15 0.2 ND 0 0 of 30

Sample locations are selected based on a review of building permits for single-family structures with copper pipes with lead solder installed in the early 1980’s (between 1982 and 1985 if available), which are considered most vulnerable to lead and copper leaching into the drinking water from household plumbing. There are no sample locations available with lead pipes or lead service lines.
