Diaminochlorotriazine (DACT) Screen ($35)
Detects argicultural chemicals called
triazines. Triazines are a class of herbicides that include atrazine,
simazine, and cyanazine. The DACT screen is an approximate test that is
performed as an inexpensive alternative to a more detailed test. It is
a useful first step in determining whether your water is being impacted
by pesticides and below health-based standards for triazine type
Nitrogen and Phosphorus (N/P) Containing Pesticides ($132)
This test is for those who have a reason to suspect contamination
(other than atrazine). We recommend homeowners have their water
tested for nitrate (see "Homeowner Package") before choosing this test. These pesticides
are more commonly used in Wisconsin agriculture. Again, this test
doesn't cover all pesticides.
Chloroacetanilide Herbicide Metabolites (CAAMs) - ($100)
These chemicals are from herbicides (alachlor, acetochlor, and
metolachlor) that have replaced atrazine. While these parent herbicides
normally degrade in the top soil, they form ethane sulfonic acid (ESA)
and oxanillic acid (OA) degradates which can penetrate to groundwater.
They have been found in groundwater in many of the agricultural areas of
the state of Wisconsin.
At this time, there is little known regarding the health
implications of drinking water contaminated with these chemicals. The
only DNR regulatory standard that exists is for Alachlor ESA. It has a
standard of 20 ppb.
