River Network’s Habitat Blog helps river advocates stay up-to-date on news, tools, and resources related to legal, policy and technical developments related to restoration and protection of river and wetland habitats. The blog is updated regularly by Merritt Frey, Habitat Program Director, and Gayle Killam, Habitat Program Deputy Director. We also welcome your comments and guest bloggers.
Our Partners are some of the smartest, wittiest and most interesting people we know...and we're not just saying that. Check out what some of them have to say via their blogs.
The Environmental Working Group has launched a new and very impressive database on drinking water violations and reporting around the country. The user-friendly system allows a user to search by zip code or supplier and then view extensive data in a non-technical format.
The National Drinking Water Quality Database covers 48,000 communities in 45 states and the District of Columbia. The data demonstrates that more than 300 pollutants were found in our tap water, and the database website goes on to say:
More than half of the chemicals detected are not subject to health or safety regulations and can legally be present in any amount. The federal government does have health guidelines for others, but 49 of these contaminants have been found in one place or another at levels above those guidelines, polluting the tap water for 53.6 million Americans.
Environmental Working Group also used their data to rate large (serving more than 250,000 people) drinking water systems based on three factors. No systems in the Intermountain West showed up in the ten "top-rated" systems. Three systems did make the ten "lowest-rated" systems list, and all of them were in Nevada -- Las Vegas, Nevada (Las Vegas Valley Water District); Reno, Nevada (Truckee Meadows Water Authority); and North Las Vegas, Nevada (City of North Las Vegas Utilities Department).
To see the rating for all the large systems reviewed, check out this list. For example, Phoenix (City of Phoenix Water Services Department) comes in at #53, Albuquerque (Albuquerque Bernalillo County Water Authority ) at #51, Tuscon (Tucson Water) at #66 and Salt Lake City (Salt Lake City Department of Public Utilities) at #80.
