Information on Sodium Levels in GU Drinking Water

Sodium is an element that is naturally occurring and is essential for life.  Sodium is naturally present in our reservoirs, and in some of our reservoirs it is at a higher level than others, possibly due to stormwater runoff from the roads.  At various times, ranging from the spring to the fall, it is advantageous to blend water from one of our reservoirs into our main reservoir to improve certain aspects of the water quality.  Unfortunately, that reservoir is one of the ones which has a higher sodium content from road salting, and this will sometimes cause our tap water to have sodium in excess of the 28 mg/L notification level (our maximum level this summer is 30 mg/L).  As required, we publish a notice in our billing statements to let our customers know this.

For most of our customers, this will not be an issue, but for customers who have been put on a very restrictive diet (less than 500 mg of sodium per day) this may be something they will want to discuss with their doctor.  To put things in perspective, 30 mg/L of sodium is equal to 7 mg of sodium in an 8 ounce glass of water; in comparison, an 8 ounce glass of 1 % milk contains 104 mg of sodium.  So if you have any concerns about sodium in drinking water please consult your physician, but for most people on a normal (i.e., non-sodium restricted) diet, Groton Utilities water would not be of concern.

Storm Preparation

house in a stormWith Tropical Storm Fay approaching there are certain things that everyone can do to be as prepared as possible should a storm hit the region.

Prepare for a Storm:

  • Have candles and flashlights available for emergency light, and a battery-operated radio for weather reports and other information. Make sure you have matches and fresh batteries, too.
  • Create an emergency kit with essential items such as food, water and communication devices. It should include non-perishable food, water bottles, medicine and supplies. There should be enough items to survive at least 72 hours.
  • If you see that a major storm is coming be sure to charge all your cellphones and tablets as well as any backup batteries you may have.
  • Please note: Customers with special medical problems such as having oxygen requirements should have a backup plan.

During an outage:

  • If all your power suddenly shuts off, the main breaker in your electrical breaker box may have tripped. You can restore power simply by moving the switch to “off,” then back to the “on” position. Check your fuses, too, if you have them.
  • If your area is without power, or you see any downed wires, call Groton Utilities at (860) 446-4000. Call us if you see damage to electrical equipment, or anything out of the ordinary such as trees or branches on wires. Do not go near any wires. Even a downed wire may be dangerous.
  • Keep refrigerators and freezers closed. Contents should be safe for at least 24 hours. Turn off your appliances. When power is restored, turn them back on gradually.
  • Don’t worry. We respond to outages immediately and continue to work until all customers have power. Once you’ve called, please resist the temptation to call back. However, if your neighbors have their electricity back and you’re still out, you should call again. In the case of a full hurricane, your patience would certainly be most appreciated.
