The Toxicity of Groundwater

Help! My Pet/Cat or Dog is drinking the groundwater out of my Sump Pit.

The Toxicity of Groundwater
It’s always a good idea to keep your sump pit empty and keep it covered. Pets should not be allowed to drink sump pit water as all kinds of bacteria and chemicals can leach into the groundwater, it might look clean, but it could contain heavy metals, like lead, cadmium, or nickel. These are known to cause cancer!

California Prop 65 and other States clean water acts

The Safe Drinking Water and Toxic Enforcement Act of 1986 requires that the Governor revise and republish at least once per year the list of chemicals known to the State to cause cancer or reproductive toxicity.

Ground water can also contain all kinds of bacteria 


Leptospirosis organisms are bacteria that thrive in wet climates. Wild animals, particularly deer and rodents, and some domesticated animals (cows, sheep and pigs) can be leptospirosis carriers. Although infected, these mammals maintain good health while shedding leptospirosis organisms in their urine.

Dogs can contract leptospirosis by drinking from water sources contaminated with urine from an infected animal. Puddles that have formed from rain runoff certainly qualify as such a source. A 2002 study on the prevalence of canine leptospirosis in the United States and Canada revealed that disease prevalence correlates with the amount of rainfall. The more rain, the more dogs diagnosed with leptospirosis.


Giardia organisms are microscopic protozoa that live within the intestinal tracts of a variety of domesticated and wild animals. The infectious (contagious) forms are shed within the feces and readily contaminate water sources. This is one of the main reasons it is recommended that drinking hikers and backpackers drink only filtered water. A 2012 study documented that dogs who attend dog parks are more likely to test positive for giardia than those who do not attend dog parks2.

The most common symptom caused by giardiasis in dogs is diarrhea. Vomiting and loss of appetite may also occur. The diagnosis is made via stool sample testing. A handful of medications can be used to rid the intestinal tract of giardia. Metronidazole and fenbendazole are the two most commonly used.
