An herbicide used on rights-of-way and crops.
In Florida, Dalapon was reported by 78 community water systems serving about 282,972 people. Every reported reading was at or below the federal legal limit. It was measured by 1,559 systems in all, so it was detected in 5% of the systems that tested for it.
The highest reading relative to the limit was at Hidden Acres Estates in Highlands County, at 2% of it.
Where it comes from: Runoff from herbicide used on rights of way.
Enforceable. A utility must stay at or under this.
Health-based, not enforceable. Often lower than the limit, sometimes zero.
California has not published a PHG for this substance.
Health effects the EPA associates with it: Minor kidney changes.
Water at or under the legal limit meets federal safety standards. A reading above a health goal is not the same as being unsafe, and health goals are set purely on health without regard to cost or treatability. Both are shown so the margin is visible either way.
