A standard operation procedure and a pilot water testing for herbicides in northwest Harris County, Texas

Herbicides are used to control the growth of weeds along highways, power lines, and many other urban locations. Exposure to herbicides has been linked to adverse health outcomes. This study was initiated to pretest for the presence of herbicides in multiple water sources near intersections in a corridor in the Northwest Harris County (specifically in the Highway 6/FM 1960, North Freeway 45, US 290 and S 99 corridor). Roadside water and tap water samples were collected and analyzed for herbicides using the established Environmental Protection Agency (EPA) Method 515.4: "Determination of Chlorinated Acids in Drinking Water by Liquid-Liquid Micro-extraction, Derivatization, and Fast Gas Chromatography with Electron Capture Detection." A standard operating procedure (adapted from the US EPA Method 515.4) was developed for subsequent, larger studies of environmental fate of herbicides and non-occupational exposure risks. Preliminary testing of 16 water samples was performed to pretest the existence of trace herbicides; all concentrations that were greater than the minimum reporting limits of each analyte are reported with a 99 percent confidence. This study failed to find concentrations above the limits of detection of the method in any of the samples collected on June 15, 2008. However, this does not indicate that the waters around the NW Harris County are free of herbicides and metabolites. A larger and repeated sampling in the region would be necessary to make that claim. ^

Editorial: The Impact of Welfare Reform on Families

On the horizon a huge wave is building, about to crash down on the poorest most hard pressed families in our country. The impact of welfare reform on families and on those who serve them will be profound The degree to which families and workers will be adversely affected is to date not fully understood. Yet as my son concluded, "...basically, if you are on welfare you had better win the lottery or learn to swim in the treacherous waters of poverty!" (C. Sallee, personal communication, November, 1996). We are also informed by looking back at the Elizabethan Poor Laws of 1601 where we find the origin of welfare reform. Orphanages, the responsibility of relatives, poorhouses and awarding relief work to the lowest private sector bidder, all introduced in the beginning of the welfare state, are key components of the current reform. The Personal Responsibility and Work Opportunity Act of 1996 washes away the entitlements and rights created during this country's greatest depression, leaving exposed the stark selfishness of the junk bond 1980's.
