WWALS sent EPA some comments on groundwater, which is very important here above the Floridan Aquifer in south Georgia and north Florida.
WWALS also signed on to comments by Waterkeeper Alliance and SELC, but SELC wrote almost nothing about groundwater, and there was more to say than was in the WKA comments. Those other comments are on the WWALS website.
The WWALS comments should appear on regulations.gov, Docket number EPA-HQ-OW-2021-0602, with Comment Tracking Number kzd-8bdc-p6xf, after EPA finishes reviewing it. Here they are in PDF and inline below.
