Trends in Groundwater System Compliance

In the Winter 2011 issue of Ground Water Monitoring & Remediation (31, Vol 1), published by the National Ground Water Association, the USEPA provides an update on compliance in the article, “Trends in Groundwater System Compliance”. The article was written by Chuck Job from EPA headquarters and here are some of the highlights:

Public Water Systems are consolidating, there has been an 8.5% decrease in the number of PWS’s in the ten years from 2000 to 2009
The number of health based violations (MCL or treatment techniques) has increased 40% in the same period.
The health based violations don’t take the Groundwater Rule into account because it had not been implemented in many systems by 2009
More than 90% of the groundwater system health based violations are from total coliform, nitrate, and arsenic.
In 2009, over 88 million US residents on Public Water Supplies were served by groundwater.
The arsenic rule changes, lowering the MCL from 50ppb to 10ppb, was implemented in 2006, in 2005 there were 23 systems with arsenic compliance violations, in 2009 there were 621.
Systems serving 500 people or less have most of the total coliform (86%), nitrate (84%), and arsenic (68%) violations.

This information and other details about PWS compliance can also be found on EPA’s website at:

Time for a Field Trip!

The new Waterworks museum in Boston tells "important regional stories about clean water, health, people, brilliant engineers, and magnificent architecture" through exhibitions and educational programs on engineering, architecture, social history, and public health.

We love seeing how partnerships in the private sector - and between the public and private sectors - can build these important resources and facilities for public education.
