Summary

The Safe Drinking Water ActSafe Drinking Water Act The main federal law that ensures the quality of Americans' drinking water. The SDWA sets the framework for the UIC Program to control the injection of fluids. EPA and states implement the UIC Program, which sets standards for safe injection practices and bans certain types of injection. (SDWA) requires closure of all large capacity cesspools (LCCs). In 2017, EPA announced an agreement with the County of Hawaii to close seven LCCs that serve the Pāhala and Nāʻālehu communities on the Island of Hawaii. The County will replace the cesspools with wastewater treatment systems approved by the Hawaii Department of Health. The Pāhala Community Large Capacity Cesspool Replacement Project is one of the projects covered by the agreement.
