Private well owners and water testing

THE IMPORTANCE OF WATER TESTING YOUR PRIVATE WELL

Water test­ing is crit­i­cal­ly impor­tant to under­stand the qual­i­ty and safe­ty of your home’s water sup­ply.  Accord­ing to the EPA, rough­ly 2.3 mil­lion peo­ple in the New Eng­land area get their water from a pri­vate well.  That’s about 20 per­cent of the region’s pop­u­la­tion. Dif­fer­ent areas of the coun­try often have dif­fer­ent water prob­lems and recent stud­ies show that methyl-ter­tiary-butyl ether (MTBE), radon, and arsenic have con­t­a­m­i­nat­ed a num­ber of pri­vate wells in New Eng­land.

The good news?  Through knowl­edge, exten­sive data, and cut­ting edge tech­nol­o­gy, water treat­ment com­pa­nies and cer­ti­fied labs can keep you in the clear when it comes to safe and healthy water. As a home­own­er, there are some things you can do to ensure the best pro­tec­tion of your well once you have water test­ing per­formed.

Keep up with the latest

If you own a pri­vate well, it’s in your best inter­est to stay cur­rent on recent ground­wa­ter stud­ies and com­mon region­al prob­lems.  At the very least, be aware of con­t­a­m­i­nants found in neigh­bor­ing prop­er­ty. To be on the safe side, the EPA rec­om­mends year­ly water test­ing for col­iform bac­te­ria, nitrates, total dis­solved solids, and pH lev­els or any oth­er poten­tial con­t­a­m­i­nants that you sus­pect your water sup­ply may be sus­cep­ti­ble to.

You can’t be too cautious.

In cer­tain sit­u­a­tions, water test­ing more than once a year may make sense. Don’t hes­i­tate to call a local expert in any of the fol­low­ing sit­u­a­tions:

  1. Some­one in the house­hold is pregnant/nursing
  2. There are unex­plained ill­ness­es
  3. You see a change in water taste, odor, col­or or clar­i­ty
  4. Any part of your well sys­tem is replaced, repaired or tam­pered with
  5. Near­by new con­struc­tion or exca­va­tion that may have impact­ed ground water aquifer flows

Be aware of other problem sources

The EPA has an exten­sive list of com­mon sources of poten­tial ground water con­t­a­m­i­na­tion. Water can be com­pro­mised by any­thing from under­ground fuel stor­age tanks to swim­ming pool chem­i­cals to near­by live­stock. Even adja­cent com­mer­cial or indus­tri­al areas with air­ports, laun­dro­mats, gas sta­tions, asphalt plants or met­al­work­ing shops, to name a few, could poten­tial­ly con­t­a­m­i­nate ground water.

This infor­ma­tion is not meant to make you para­noid as your water could be per­fect­ly fine even in high­er-risk areas. Just be informed and be pre­pared. The best way to detect health relat­ed water con­t­a­m­i­nants is by get­ting a prop­er­ly pulled sam­ple to a state cer­ti­fied lab. If you sus­pect any issues with your pri­vate well, need to sched­ule rou­tine annu­al water test­ing, or need help find­ing a cer­ti­fied lab near you that can test your water, call H2O Care at 800–539-1100 or email us at [email protected]

What is salt water intrusion?

Salt water intru­sion occurs in coastal fresh­wa­ter aquifers when the dif­fer­ent fresh­wa­ter and salt water den­si­ties allow the intru­sion of ocean water into the fresh­wa­ter aquifer. These areas typ­i­cal­ly sup­port pop­u­la­tions where the ground­wa­ter demand from these aquifers exceeds the recharge or replen­ish­ment rate of fresh water. This can become more like­ly when the water is being used for in-house use as well as lawn irri­ga­tion. Irri­gat­ing with salty water will destroy grass, trees and plants.

Aquifers are nat­u­ral­ly replen­ished by pre­cip­i­ta­tion and sur­face waters that sat­u­rate into the ground and work their way through the soil, rocks, etc. to the water table. The encroach­ing sea­wa­ter will encounter an area known as the zone of dis­per­sion, where the fresh­wa­ter and salt­wa­ter mix. This inter­face moves back and forth nat­u­ral­ly because of fluc­tu­a­tions in the recharge rate of fresh­wa­ter back into the aquifer.  The illus­tra­tion below gives an illus­tra­tion of what this salt water intru­sion looks like.

THE SOLUTION

There are many homes with pri­vate wells near coastal areas where there is no access to pub­lic water sup­plies, because of dis­tance to the water dis­tri­b­u­tion sys­tem or oth­er rea­sons.  When the well expe­ri­ences salt water intru­sion, the proven and test­ed tech­nol­o­gy to desali­nate the water is reverse osmo­sis, a mem­brane tech­nol­o­gy that was invent­ed in the 1950s specif­i­cal­ly for sea water desali­na­tion.  A sys­tem designed to treat the water at the point of entry into the home will cor­rect this salt water intru­sion.  In fact, the water in the toi­lets will be of high­er qual­i­ty than what most peo­ple drink out of their taps!
