migration into ground waters. <br />• Biosolids produced for lawns and gardens in Colorado have been <br />composted. This additional processing reduces the nitrogen content to <br />low levels. This product is used primarily for its organic matter as a soil <br />amendment and for the micronutrients such as copper and zinc. Rec- <br />ommendations for loading rates are on the bags or can be obtained from <br />the producer when the compost is purchased in bulk. <br />What Role Does the Colorado Department of Public <br />Health and Environment Play in Ensuring the <br />Quality and Safety of Biosolids? <br />The Colorado Department of Public Health and Environment regu- <br />lates the quality and use of biosolids through its Biosolids Management <br />Program. It also administers and enforces the National Pretreatment <br />Program that the Clean Water Act mandates. Pretreatment, or source <br />control, programs establish strict rules for industries that discharge <br />pollutants such as copper, zinc, or other metals or toxins to a publicly <br />owned wastewater treatment plant. Compliance by industry and strict <br />enforcement of the pretreatment program by state and local authorities <br />ensures that the wastewater treatment processes are working effectively, <br />thus improving the quality and safety of biosolids. <br />How Do I Find Out More <br />About Biosolids? <br />As Colorado's population grows, so will the amount of biosolids <br />produced. Finding alternatives for biosolids use depends greatly on the <br />acceptance of this valuable product by Colorado citizens. The Colorado <br />Department of Public Health and Environment, the U.S. Environmental <br />Protection Agency, and others working with biosolids recycling invite you <br />to take an active role in learning more about the wastewater treatment <br />process and the generation and recycling of biosolids in your community. <br />For further information about biosolids please contact: Bob Brobst, <br />USEPA VIII, 999 18th St., Suite 500, Denver, CO 80202, (303) 312-6129, <br />or Wes Carr, Colorado Department of Public Health and Environment- <br />Water Quality Control Department, 4300 Cherry Creek Drive South, <br />Denver, CO 80222-1530, (303) 692-3613. <br />0 First Printing: 1995 <br />Revised 2002
