Since 1993, several wells have been found to be contaminated in Randolph Township, New Jersey. As a result, the local health department believed there was a need to develop an ordinance that would protect the health of private well users. Samplings of 1,488 private and nonpublic wells in Randolph Township were used to provide the basis for the ordinance proposal. Questionnaires were mailed to homeowners, and samples were collected to be evaluated for the presence of volatile organic compounds (VOCs), coliform bacteria, and other inorganic water quality criteria. Several VOCs were shown to be present in the residential water supplies, with more than half of them being chlorinated hydrocarbons. These chlorinated hydrocarbons are generally utilized in industry, at service stations, and as cleaning agents for septic systems; they were detectable within one quarter of a mile from stationary sources or industrial areas. Similar trends were seen for coliform bacteria and other inorganic products. The health department advised residents at sample sites when contamination was found.
自1993年以来,新泽西州伦道夫镇的几口井被发现受到污染。因此,当地卫生部门认为有必要制定一项条例,以保护私人水井使用者的健康。对伦道夫镇1488口私人和非公共水井进行采样,为该条例提案提供依据。向房主邮寄了调查问卷,并采集样本以评估挥发性有机化合物(VOCs)、大肠菌和其他无机水质标准的存在情况。结果显示,居民供水系统中存在几种挥发性有机化合物,其中一半以上是氯代烃。这些氯代烃通常用于工业、加油站以及作为化粪池系统的清洁剂;在距固定源或工业区四分之一英里范围内即可检测到。大肠菌和其他无机产物也呈现出类似趋势。当发现污染时,卫生部门会通知采样点的居民。
