County’s letter to TCEQ

The morning after the Commissioner’s Court unanimously passed a Resolution opposing the Denali permit application, Judge Paul Pape sent this strongly worded letter to the TCEQ. Kudos to the Court for standing up to this ill-conceived proposal! Well done, one and all!!

Another citizen speaks

At Monday’s Commissioner’s Court session, Chris Denison read this comment that was submitted to the TCEQ regarding the Denali Permit Application.

The area of Bastrop County being considered for sewage dumping is underlain by a rock unit called the Calvert Bluff Formation. This unit consists of layers of sands, shales and lignites, sometimes cut by sand-filled channels. All of the aquifer sands are connected to some extent, vertically and laterally. Water wells can produce from the layered sands at fairly low rates, but if you are fortunate enough to have a well that produces from a channel sand, copious amounts of water can be produced.

The Calvert Bluff dips (is inclined) to the southeast at about 100 feet to 200 feet per mile. For example, I have property on Lone Star Road, to the southeast of the intended dumping area, and I am producing water from a sand at 300 feet. That sand comes to the surface somewhere between 3 and 6 miles away, which is where the sludge will be dumped. That is where my aquifer sand is recharged.

Surface water soaks into the ground and slowly moves through the aquifer, spreading vertically and laterally, reaching my well possibly years to decades later. Any pollutants on the surface of the recharge area will be transferred into the aquifer and will eventually reach my well. Hundreds of household wells down-dip from the proposed dumping area are potentially at risk.

As an illustration of what will happen, during WWII what is now Livermore Labs in California was an airbase. On grassed areas of the airbase, oil-coated aircraft engines were washed with carbon tetrachloride (dry-cleaning fluid), which “disappeared”. Decades later, a plume of contaminated groundwater is moving towards Livermore City water wells.

Sewage sludge is notorious for containing pharmaceuticals flushed down toilets and heavy metals, including lead, mercury, arsenic and cadmium, from various household cleaning products. Complex molecules from the pharmaceuticals will break down, but the surviving molecular fragments and the heavy metals will be washed into the aquifer. I will have to pay for tests to determine when the pollutants reach my well. When this toxic chemical soup eventually appears, I will not be able to use the water in my house, for my animals, or for irrigation. What do I do then - move?

Sludge exposes a stink

More Harm than Good

From Mother Earth News Biosolids: More Harm than Good two interviews with David Lewis by Lidia Epp.

Introduction

David Lewis, Ph.D., formerly a senior-level research microbiologist at EPA-ORD, was terminated by EPA for publishing two articles in Nature that raised concerns over the 503 sludge rule. He currently serves as director of research for the Focus for Health Foundation. Dr. Lewis kindly agreed to an interview for the MOTHER EARTH NEWS blog addressing the issue of agricultural use of sewage and industrial sludge, aka – biosolids. He is one of the most prominent scientific voices in the growing opposition to biosolids land application. Dr. Lewis’ publications are frequently cited as an example of solid, unbiased scientific evidence of the danger posed by this practice.

A Whistleblower’s Story

How EPA Faked the Entire Science of Sewage Sludge Safety

Introduction

US EPA’s 503 sludge rule (1993) allows treated sewage sludges, aka biosolids, to be land-applied to farms, forests, parks, school playgrounds, home gardens and other private and public lands. According to a recent EPA survey [1], biosolids contain a wide range of mutagenic and neurotoxic chemicals, which are present at a million-fold higher concentrations (ppm versus ppt) compared with their levels in polluted air and water (1). Biosolids contain all of the lipophilic (fat-soluble) chemical wastes that once polluted our rivers and lakes , but which now settle out at sewage treatment plants and become concentrated in sewage sludges. Most biosolids contain ppm concentrations of heavy metals, including chromium, lead, and mercury. They contain similarly high levels of polycyclic aromatic hydrocarbons (PAHs) and semi-volatiles, such as bis (2-Ethylhexyl) phthalate, Benzo(a)pyrene), and polybrominated diphenyl ether congeners (PBDE flame retardants). Most biosolids also contain pathogenic agents and ppm levels of many common drugs, including ciprofloxacin (Cipro), carbamazepine (Tegretol, Equetro), and fluoxetine (Prozac).

While working at EPA Dr David Lewis published evidence that teenager Shayne Conner (of New Hampshire) died and other neighbors were harmed from living near land applied with sewage sludge (Lewis et al 2002[2] ). He furthermore became involved after dairy herds of two Georgia farms (McElmurray and Boyce) were poisoned after grazing on sludged land. He testified in lawsuits following each incident, against his employer (EPA), which is where many of the following depositions were obtained. The following article is an excerpt from Chapter 4 (Sludge Magic) of his new book (Science for Sale: How the US Government Uses Powerful Corporations and Leading Universities to Support Government Policies, Silence Top Scientists, Jeopardize Our Health, and Protect Corporate Profits [3] ).

The lawsuits referred to are Lewis v. EPA 1999; Lewis v. EPA 2003; and USA, ex rel. Lewis, McElmurray and Boyce v. Walker et al. 2009.

The depositions below piece together an unprecedented and coordinated multi-agency scientific scheme involving EPA, USDA, local and city municipalities, Synagro Technologies (a waste management company), various universities, and the National Academies of Science.

The effort was intended to misleadingly present sewage sludge as scientifically safe, to hide the evidence that it was not, to deliberately misreport the contents of municipal sludges, and smear David Lewis with a scientific misconduct charge after he blew the whistle.
