Install fiber optic cable to detect groundwater upwelling in small section of Newtown Creek Canal in New York City. The site has DNAPL contaminants.

At a New York study area 1.2 acres of sediment were monitored for evidence of groundwater seeps using a fiber optic distributed temperature sensor (DTS). A fiber optic cable was installed and monitored, providing 1.0 kilometers of cable laid out in six transects, each approximately 140 m in length and separated by 5-8 m. The DTS system recorded sediment temperatures at half-meter intervals every 20 minutes in September, 2019, yielding approximately 1.5 million temperature measurements during the study. Temperature data was analyzed through a suite of analytical methods to identify potential groundwater discharge locations.

本研究在纽约一处1.2英亩的沉积区域开展，采用光纤分布式温度传感器（fiber optic distributed temperature sensor, DTS）监测地下水渗出的相关证据。研究团队布设并监测了一条总长1.0千米的光缆，该光缆分为六条测线，单条测线长度约140米，测线间距为5至8米。该DTS系统于2019年9月以每20分钟一次的频率，以0.5米为间隔记录沉积物温度，本次研究共获取约150万条温度测量数据。研究团队通过一系列分析方法对温度数据进行处理，以识别潜在的地下水排泄点位。
