*The DNR is seeking public comments on proposed rules that would 
establish requirements to protect and manage the water quality of Iowa’s 
surface waters.* **

Recently, the DNR began to compile research related to toxicity of total 
dissolved solids, chloride and sulfate. The purpose was to update and 
develop criteria for these parameters to better protect aquatic life 
based on new scientific information.

People can comment on the proposed rules orally or in writing at seven 
public meetings, listed alphabetically by town:

· Atlantic: 10:00 a.m. July 15, Atlantic Public Library, 507 Poplar St.

· Clear Lake: 11:00 a.m. July 16, Clear Lake Public Library, 200 N. 
Fourth St.

· Des Moines: 1:00 p.m. July 9, fifth floor conference rooms of the 
Wallace State Office Building, 502 E. Ninth St.

· Dubuque: 11:00 a.m. July 13, Dubuque Public Library, 360 W. 11th St.

· Iowa City: 6:00 p.m. July 13, Iowa City Public Library, 123 S. Linn St.

· Orange City: 11:00 a.m. July 7, Orange City Public Library, 112 Albany 
Avenue SE

· Spencer: 6:00 p.m. July 7, Spencer Public Library, 21 E. Third St.

The proposed changes would:

    * Establish numerical water quality criteria for chloride, for the
      protection of aquatic life
    * Establish numerical water quality criteria for sulfate, for the
      protection of aquatic life and livestock watering
    * Remove criteria for total dissolved solids and associated
      implementation procedures.
    * Revise the default hardness level used for hardness-dependent
      chemical criteria
