See the tiny balls of white stuff next to the edge of the turf grass? Those re pellets of chemical fertilizer spilled on the impervious surface of the sidewalk by the fertilizer applicator. The first rain event that comes long, in turn, washes these pollutants into the nearest storm drain. From there, they travel (along with a lot of other gunk) into the watershed's principal receiving streams and lakes. In this case, that's Lake Champlain. No wonder the lake's water quality is worsening -- all in the name of the great all-American lawn.

Vermont government and cleaning up Lake Champlain
Gov.Peter Shumlin can start by asking counties and municipalities within them to stop the clearing of forests and the subsequent conversion of that land to crap like parking lots, driveways and even lawns, all of which contribute a hell of a lot of nutrient pollution to Lake Champlain via its tributaries (Winooski River, Otter Creek, Mississquoi River, Lamoille River, etc.). Then, having declared that water quality means more than a developer's bankroll, we can all start restoring the natural landscape - the landscape that's critical toward filtering surface waters and, ultimately, to cleaning up the big lake's water. So, come on,folks. Let's get going on this. Here's Vermont Public Radio's take on the governor and the lake.

Surprise: We all live downstream
I’ve lived and worked in many
watersheds in my 60-plus years.
There’s the Rio Grande in New Mexico;
the Platte River in Nebraska; Lake Champlain (once at Plattsburgh Air Force
Base on its west side, in New York State, and now on the east side, in
Vermont); Lake Thunderbird and the Canadian River in Oklahoma; the Snake River
in Idaho; and the Lower Ocmulgee in central Georgia.
They all have lots in common, much of
it on the negative side of the graph, unfortunately: The loss of natural land
to sprawl and the gougers, diggers, bulldozers, chainsawers, polluters, dam
builders, graders and asphalters of urban America.
My home in Vermont is – like yours in
Pennsylvania – actually in several watersheds. First is the Winooski River (I
live a half-mile from it). Second, and much larger, is the Lake Champlain
watershed, which is international and multi-state in scope.
“We all live in a watershed,” reads the
election campaign-style lapel button I got from the Puget Sound Partnership in
Washington State some years ago.
That conservation outfit is correct. We
do.
The EPA gives us this definition: “A
watershed is the area of land where all of the water that is under it or drains
off of it goes into the same place. John Wesley Powell, scientist geographer,
put it best when he said that a watershed is: ‘that area of land, a bounded
hydrologic system, within which all living things are inextricably linked by
their common water course and where, as humans settled, simple logic demanded
that they become part of a community’."
Many residents of metro Hazleton
(oftentimes called “Greater Hazleton”) live in the Chesapeake Bay watershed,
but neighbors in Carbon County reside in the Lehigh River watershed, part of
the Delaware River’s watershed.
Roads, homes and other human activities
have altered the composition of forests across the Chesapeake Bay watershed
(and all the others, too), reducing tree cover and fragmenting those forests
that still exist.
Fragmented forests are less resilient
to disturbances and more prone to negative influences like wildfires and
invasive species. The ongoing loss of trees and entire forests, with financial
profit the true motive, toughens and heightens cost and the cleanup and
restoration.
But just because some thousands of
acres are (thankfully) owned by a public agency, the Hazleton City Authority,
as watershed land, does not mean Pennsylvanians need not worry about the
ecological health of that land or, even more so, the diminishing naturalness of
other land, private or public, elsewhere in the same watershed.
The logging of hardwood trees relates
poorly to the goal of healthy watershed land and the replenishment of
groundwater.
The Chesapeake Bay Program: “Forests
are critical to the health of the Chesapeake Bay. Large stands of trees can
protect clean water and air, provide habitat to wildlife and support the
region’s economy.
“But human activities have altered the
watershed’s forests, reducing tree cover and fragmenting forests that still
exist. Conserving and expanding forest cover is a critical, cost-effective way
to reduce pollution and restore the Bay.”
Streams across the United States are
suffering a decline in health, as human development alters stream flow and
pushes pollutants into the water. It’s a sad commentary on our times when one
can stand on the shore of a major Chesapeake tributary (like the York River at
Yorktown) and watch as rainwater polluted with the blue sheen of automobile
engine oil dribbles into the current and out into the Bay. I’ve watched that
process, a bunch of times.
The Bay Program (www.chesapeakebay.net/issues): “There are two broad categories of chemical contaminants
that can be found in the Chesapeake Bay and its tributaries: metals and
organics.
Mercury is the most common metal found
in the Bay watershed.
Common organic chemical contaminants
include:
-
- Polychlorinated
biphenyls (PCBs), which act as a flame retardant in electrical equipment.
Though their production has been banned since 1977, PCBs still pose a risk to
humans and wildlife because they persist in the environment.
-
Polycyclic aromatic
hydrocarbons (PAHs), which form when gas, coal and oil are burned. PAHs are
common in areas with high rates of development and motor vehicle traffic.
-
Organophosphate
pesticides (OPs), which are mostly herbicides and insecticides used in
agriculture. OPs can affect functioning of the nervous system.
-
Storm runoff from
cities, towns and suburbs picks up oil, pesticides and other chemicals as it
flows across lawns, roads, and parking lots and into nearby streams and storm
drains. This type of pollution is significant and difficult to control.
Protecting the sources of our clean drinking water does not fit well with
the selling of saw timber or the building of a road to get the truck in and the
cut out. Every municipal water agency in Pennsylvania could preclude all sorts
of problems, some of which I’ve discussed, by buying and protecting natural
lands.I call it Wild Nature and it’s where good water and a lot more come from.
