Nitrates are a chemical product of sewerage breakdown. In Canada, the safe limit set for nitrates in drinking water is 10mg/L. In much higher amounts, nitrates have been known to cause infant death. Savary Shores well-1 water had been stable for 8 years at average 3.47mg/L, and well-2 for 3 years averaged 1.98mg/L. In 2017, both readings jumped inexplicably to averages of 4.76mg/L and 2.45mg/L. To monitor the situation, SSID's Operator is now taking nitrates tests monthly. Since the spike, nitrates levels have declined. These Nitrates Tables will be updated monthly.
