Japanese authorities have been pumping that water into a vast array of tanks on-site: currently over a thousand tanks, and adding around one new tank per week. Now, Japanese authorities are preparing to release that water into the Pacific Ocean. Before they do that, they'll treat the water to cleanse it of radioactive contaminants.

Tire wear particles pollute the environment, the air we breathe, the water run-off from roads and has compounding effects on waterways and agriculture. Tire waste does not naturally degrade and instead builds up in the environment, and may interact with other pollutants as well as biological organisms. Water Research 139, 83-100.
Algae have the potential to produce large volumes of fuel per unit area of production on marginal lands using saline water unsuitable for food crops. Thus, algal biofuels could expand transportation energy supplies, without significantly displacing land and water resources that would otherwise have been used for food production.
An international study of 10 global cities found that a balance of geophysical factors (climate, access to resources, and gateway status) and technical factors (power generation, urban design, and waste processing) determine the greenhouse gas emissions (GHGs) attributable to cities. Reviews by Decker et al. and Kennedy et al.
It should be noted that none of these values explicitly consider local factors promoting GHG emission other than water depth (e.g., The University of Leicester researchers carried out the first comprehensive literature review of the scale of greenhouse gas emissions from oil palm plantations on tropical peatland in Southeast Asia.
