- HAA5 and HAA9 are byproducts of chlorine treatment, a common method of disinfecting water supplies. They can be filtered out using carbon filters (See below).
Let’s look closer at what’s in Greenwood water.
What’s in Greenwood water?
Here are the top 3 chemical compounds in your water and what health issues they can potentially cause:
- Haloacetic acids (HAA5) – Potential effect: Cancer
- Haloacetic acids (HAA9) – Potential effect: Cancer
- Total trihalomethanes – Potential effect: Cancer
These are three of the 13 contaminants analyzed by the Environmental Working Group (ewg.org).
These 3 contaminants are rated as exceeding EWG Health Guidelines.
Does Greenwood have Lead contamination?
Yes, Greenwood has lead in its water. The most recent Lead samples collected from 2016 through 2018 showed concentrations up to 4.0 parts per billion (ppb).
The legal limit for lead is 15 parts per billion. Being well-below this level is a good thing.
- Concentrations between 3.8 ppb and 15 ppb put a formula-fed baby at risk of elevated blood lead levels. Read more about the symptoms of Lead in water.
There is no safe level of lead for humans.
- The good news is that 99.99% of the lead can be filtered out.

Conclusion – What Can You Do?
Information about water quality in Greenwood can be surprising.
But there’s no reason to lose hope. There are things you can do in your home as well as things you can do at a community level.
- Use Berkey filters with activated carbon to filter out at least 77% of contaminants in your drinking water.
- To filter out 11 of the 13 contaminants, consider a Reverse Osmosis Pentair water filtration system for your house.
- These are more expensive than pitchers to purchase, but are much more effective.
- They have the benefit of filtering out heavy hitters like:
*Chlorination is an effective method of disinfecting/treating drinking water. You can then use a water filter to reduce the effects of chlorination byproducts to get the safest, cleanest water possible.
