Health
Effects & Description |
| Final
Rules |
| Filter Backwash Recycle Rule |
Gastrointestinal Illness, Cryptosporidiosis:
Requires treatment of filter backwash water
that is recycled within the treatment process. |
| Arsenic Rule |
Skin/Bladder Cancer, Cardiovascular
Disease, Reproductive/Developmental Effects:Set
a new Maximum Contaminant Level (MCL) for
arsenic. (Under review) |
| Unregulated Contaminant Monitoring
Rule |
Requires monitoring of selected
contaminants to develop occurrence data. |
| Radionuclides Rule |
Genetic Mutations, Kidney Toxicity,
Cancer: Revised some radionuclide MCLs, added
an MCL for Uranium, and included radionuclides
in the Standardized Monitoring Framework. |
| Public Notification Rule |
Revises the regulations for
notifying the public of SDWA regulation violations. |
| Lead and Copper Minor Revisions |
Developmental Delays, Kidney
Damage, Gastrointestinal Distress: Changes
to the Lead and Copper Rule |
| Interim Enhanced Surface Water
Treatment Rule |
Gastrointestinal Illness, Cryptosporidiosis:
Modifications to the Surface Water Treatment
Rule to improve operation performance of drinking
water treatment plant to remove cryptosporidium
and other microbiological contaminants. |
| Stage 1 Disinfectants and Disinfectants
By-Products Rule |
Bladder Cancer, Reproductive
Effects: Sets MCLs to reduce disinfectant
and disinfectant by-products that may be found
in the treatment plant and distribution system. |
| Consumer Confidence Rule |
Requires community water systems
to create an annual report that provides information
on sources, source protection, detected contaminants,
health effects and water system contacts. |
| Variance and Exemptions Rule |
Sets the terms and conditions
under which a water system could get permission
to exceed an MCL on a temporary basis. |
| Long Term 1 Enhanced Surface Water Treatment
Rule and Filter Backwash Rule |
Gastrointestinal Illness, Cryptosporidiosis:
This rule is basically the same as the Interim
Enhanced Surface Water Treatment Rule, only
it applies to systems serving populations
under 10,000. |
| Groundwater Rule |
Gastrointestinal Illness: Regulations to protect groundwater sources from microbiological contaminants. |
| Long Term 2 Enhanced Surface Water Treatment Rule |
Reduce illness from microbial pathogens, specifically including Cryptosporidium |
| Stage 2 Disinfectants/ Disinfection Byproducts Rule |
Reduce cancer risks from byproducts that form during drinking water treatment. |
| Proposed
Rules |
| Radon Rule |
Lung Cancer, Stomach Cancer:
Proposes an MCL for radon in water and includes
an alternative MCL based on mitigating radon
in indoor air. |
