Pollutant Loading from Low-Density Residential Neighborhoods, Califorina

Bale AE, Greco SE, Pitton BJL, Haver DL, Oki LR. Pollutant loading from low-density residential neighborhoods in California. Environmental monitoring and assessment. 2017 Aug;189(8):386. doi: 10.1007/s10661-017-6104-2.

This paper presents a comparison of pollutant load estimations for runoff from two geographically distinct residential suburban neighborhoods in northern and southern California. The two neighborhoods represent a single urban land use type: low-density residential in small catchments (<0.3 km2) under differing regional climates and irrigation practices. Pollutant loads of pesticides, nutrients, and drinking water constituents of concern are estimated for both storm and non-storm runoff. From continuous flow monitoring, it was found that a daily cycle of persistent runoff that peaks mid-morning occurs at both sites. These load estimations indicate that many residential neighborhoods in California produce significant non-storm pollutant loads year-round. Results suggest that non-storm flow accounted for 47-69% of total annual runoff and significantly contributed to annual loading rates of most nutrients and pesticides at both sites. At the Southern California site, annual non-storm loads are 1.2-10 times higher than storm loads of all conventional constituents and nutrients with one exception (total suspended solids). At the Northern California site, annual storm loads range from 51 to 76% of total loads for all conventional constituents and nutrients with one exception (total dissolved solids). Non-storm yields of pesticides at the Southern California site range from 1.3-65 times higher than those at the Northern California site. The disparity in estimated pollutant loads between the two sites indicates large potential variation from site-to-site within the state and suggests neighborhoods in drier and milder climates may produce significantly larger non-storm loads due to persistent dry season runoff and year-round pest control.

California Drowning in the Swamp of SB 32 Emission Goals

“The emissions reduction leadership role for California championed by the L A Times is touted despite the fact that our state doesn’t have the foggiest idea of how it can achieve its SB 32 emissions goals nor does it have any idea of how many tens of billions it will cost nor care at all about how the state will end up dictating how all Californians must live their lives.” click here

California’s Unsustainable Infrastructure the Result of an Unsustainable State Government

“The Federal Energy Regulatory Commission (FECR) forensic audit of the Oroville Dam Spillway crisis project found that failures were due to inadequate California Department of Water Resources (DWR) maintenance, repair of cracks, thin concrete slabs, poor drainage, and use of weathered rock.” click here

California Republicans Stray over to the Dark Side

 

California’s cap and trade approach is simply not sustainable. It’s like shooting yourself in the foot.  

“A small group of California Republican legislators are reversing their opposition to AB 32 — the “Global Warming Solutions Act” — and embracing California’s controversial climate change policies.” click here

California Climate Protesters Resist Reality

These “resistance” protestors are simply resisting reality and common sense.

“Approximately 5,000 activists rallied in San Diego on Saturday as part of approximately 300 coordinated sister marches across the United States to call on the Trump administration to take action on climate change.” click here

California Drought Moves Through the Central Valley

“The U.S. Bureau of Land Management has allocated100 percent water deliveries to Central Valley water districts for the first time in a decade, as the 80-degree weather this weekend causes risk of rapid snowmelt flooding.” click here
